EXECUTIVE SUMMARY
Constructed in 1957, with a major addition in 1971, Severna Park High School in Severna Park,
Maryland is well maintained and structurally sound. However, it does not provide an optimum
teaching and learning environment for the students of Anne Arundel County. As it exists, the facility
does not meet the current Educational Specifications requirements for a standard Maryland high
school in several categories of program and area. Overall, the physical learning environment at
Severna Park High School is deficient due to a lack of space, inflexibility of the existing spaces, a
dearth of natural light in classrooms, aging building systems, and a sprawling layout. Site safety and
vehicular circulation are difficult to manage as buses line up in the same lanes as parents and wind
through the staff parking lot.
This study was commissioned to assist the Board of Education in assessing its options to improve
Severna Park High School’s facility to meet the approved Educational Specifications. Following
AACPS’s established protocol for feasibility studies, five options were evaluated. Due to the
significance of considering relocating the existing stadium to fully assess Option E - Complete
Replacement On-Site, an alternative on-site replacement scheme was evaluated and is presented in
this study as Option F.
Conclusions:
1. Option A – Do Nothing
In this no cost option, no work would occur on site, or in the building. This option establishes a
base line for comparison to other schemes.
2. Option B – Patch and Paint
This minimum approach will repair some deferred maintenance items and provide a fresh coat of
paint throughout the existing facility. Building and life safety concerns will not be addressed.
Building systems will not be updated or replaced. No site improvements will be made to improve
circulation and safety. Students will remain in the facility during the maintenance work.
3. Option C – Revitalization
Building and life safety issues will be corrected in the existing building. Additions will be
constructed to provide new spaces for a gymnasium, physical education department, auditorium,
theatre, music, some classrooms, and food service areas. Portions of the existing building are
required to be demolished to accommodate the additions. New windows, doors, casework, and
finishes will be provided in the remaining areas of the existing building though no significant
structural changes will be made. Thus, deficiencies will remain with regard to the area
requirements of the Educational Specifications. Site improvements will include a separate lot for
bus stacking. Relocatable classrooms will be required as students will remain in the facility
during construction.
4. Option D – Modernization
This option completely renovates the existing building so that with additions, the facility will
comply with all requirements of the Educational Specifications and current codes. The building
efficiency is equivalent to Revitalization as the general floor plan is the same and remains
expansive. Site circulation and safety are improved with the creation of a separate bus stacking
Page 3 of 112
Feasibility Study
lot. Relocatable classrooms will be required as students will remain in the facility for the duration
of construction.
5. Option E – Complete Replacement On-Site ‘A’
A new facility designed in accordance with the Educational Specifications will comply with
current building, life safety, and accessibility codes and standards. Designed to achieve the
United States Green Building Council’s (USGBC) Leadership in Energy and Environmental Design
(LEED™) Silver certification, the new building will provide a safe, healthy, and inspiring learning
environment. To accommodate the existing stadium, the building will be constructed in phases
and located on existing play fields. Students will remain in the existing building during
construction of the new building, but will also have to occupy the first phase of the new building
while the second phase is under construction. Site safety and circulation will be improved.
6. Option F – Complete Replacement On-Site ‘B’
Similar to Option E, this new building will comply with the Educational Specifications, current
codes, and be designed to achieve USGBC LEED™ Silver certification. Relocation of the stadium
in this option allows for the design of the most compact floor plan which optimizes building
efficiency, requires the shortest construction timeframe, minimizes disruptions to school
operations, and allows for optimal solar orientation to maximize daylighting in classrooms. Play
fields and courts are grouped together efficiently. Site safety and circulation will be improved
with full separation of vehicular circulation patterns.
Following, on page five, is a comparison of overall building area, estimated construction cost, and
40-year life cycle operational cost between the options. Refer to Appendices A and B for detailed
analyses of the construction costs and life cycle costs presented.

Feasibility Study
INTRODUCTION
This feasibility study was conducted for Anne Arundel County Public Schools. The Study Committee,
included educators, planners, parents, community members, architects and engineers as well as a
participant from Maryland State Department of Education.
The existing State Rated Capacity of the facility is 1,805 and the current Full Time Enrollment is
1,923. Projected Full Time Enrollment in 2016 is 1,819 with a State Rated Capacity of 1,993 upon
completion of renovations to bring the facility in to compliance with the approved Educational
Specifications.
The focus of this study is to evaluate design options for five approaches to modify Severna Park
High School. These are as follows: No Changes; Patch/Paint; Revitalization; Modernization; and
Replacement School.
GWWO, Inc./Architects would like to thank the members of the Severna Park High School Study
Committee for their time and effort in helping to develop this study. The Committee’s input and
creativity has proved invaluable in understanding and addressing the needs of Severna Park High
School.
Methodology / Process
The Study Committee completed multiple tasks to develop this Feasibility Study. The process
involved multiple meetings to identify project goals, evaluate and identify approaches and individual
schemes. Additional tasks, including field investigations; review of drawings of the existing building;
code/ADA analysis and preliminary reviews were conducted by the Architect/Engineering team to
determine the impact of the existing building systems on the various schemes.
Based on the above analysis, the Study Committee developed advantages, disadvantages and costs
associated with each of the schemes. The Committee then evaluated these factors to consider how
each scheme addressed the project goals and facility needs of Severna Park High School.
AACPS System Goals:
GOAL I – ACADEMIC ACHIEVEMENT
All diploma-bound students will reach high standards, as established by Anne Arundel County Public
Schools and state performance level standards in English/Reading/Writing/, Mathematics, Science
and Social Studies. Achievement disparities among all No Child Left Behind (NCLB) groups of
students will be eliminated.
GOAL II – SAFE AND SUPPORTIVE LEARNING ENVIRONMENT
All students will be educated in a safe, positive, and supportive learning environment with a focus on
security enhancements that support system-wide safety and discipline standards. AACPS will
eliminate disparities among all No Child Left Behind (NCLB) student groups in the referral,
suspension, and expulsion rates for violation of the Code of Student Conduct.

HISTORY
Severna Park High School is a two story masonry building of 296,191 GSF located at the
convergence of Robinson Road and Benfield Road in Severna Park, Maryland. The original building
was constructed in 1957. A major addition in 1971 included a new media center, classrooms, minigymnasium with support space, and new administration offices. In 1982 the cafeteria was
expanded. Other renovations have included HVAC improvements, boiler replacement, roof
replacement, science lab renovations in 2003, and installation of an artificial turf field in 2008. Toilet
rooms were upgraded to meet requirements of the Americans with Disabilities Act (ADA). However,
the remainder of the building has not been renovated to comply with ADA codes.
There is currently one relocatable classroom on site which houses a music class.
The existing building is not known to be historically significant, but the school and local community
take great pride in the high school.
Most of the existing finishes in the school are original. Many of the interior materials, such as
casework, masonry walls, and doors, are in good condition. A good portion of exterior brick veneer
on the original building however is deteriorating due to water infiltration.
The site is just over 40 acres and has approximately 485 parking spaces. The following athletic
facilities are on site: football field, bleachers, tennis courts, practice and multi-purpose fields,
baseball field, softball field, and basketball courts.

the property is 03-000-00477223. The
site is comprised of several properties
WEST SEVERNA PARK
purchased by the Board of Education of
Anne Arundel County beginning in 1956 and ending in 1977. Deeds for the property can be
found at the Anne Arundel County courthouse at Liber/Folio’s 1052/207, 1107/ 578,
1155/413, 1222/298, 2804/720, 2812/ and 2953/181.
The property is bounded by an Anne Arundel County Recreation and Parks property known
as Cool Pond Park and/or the Jennings Road recreational area (which also currently contains
a portion of the High School’s baseball field and the softball field) and a single family home
residential development known as Wicklow to the east. Robinson Road, Benfield Road and
several single family home residential developments known as Severna Gardens, West
Severna Park and Evergreen Estates to the south. A single family home residential
development known as Severna Forest is located to the west and a single family home
residential subdivision is also located to the north.
1.2
Site Circulation and Parking
There are two access points into the
site. The main entry is located along
Robinson Road and allows for bus and
a majority of the vehicles to access the
school. A loop road is located
approximately 100’ into the site along
the left hand side of the drive. This
loop road parallels the front of the
school and is approximately 650’ long.
The secondary access is via a lighted
intersection at the convergence of
Benfield Road, Evergreen Road and
Robinson Road and allows for access
into the main student parking area.

Feasibility Study
Pedestrian access mainly occurs off of Benfield Road and Robinson Road along the entire
property frontage and requires pedestrians to cross vehicular drives to gain access to the
building. The concrete walks and paving throughout the site are in poor condition.
There are three distinct parking areas indentified on site. The main student lot is located off
of the signalized intersection to the west of the building and allows for the parking of 228
vehicles (4 Handicap). The location of this lot is also conducive to parking for sporting events
occurring at the stadium field, tennis courts and/or any of the turf fields. Additional
vehicular access from this lot to other paved areas on site is not available. The second large
parking area is located to the far east of the school and is accessed via the main drive. This
parking lot is mainly used by faculty and visitors and allows for the parking of 203 vehicles
(12 Handicap). There is a third and smaller parking lot located east of this parking area
adjacent to the existing basketball courts which allows for the parking of 54 vehicles (0
handicap spaces). Both of these lots are somewhat conducive to parking for sporting events
that occur at the baseball and softball fields. Vehicles were noticed parked in the service
yard but no striped spaces were observed.
The school is currently served by 26 buses which enter the site via the main entry drive.
Stacking for the buses is awkward and requires the buses to meander through the main
parking lot along the perimeter parking lot drive, eventually ending up at the loop road in
front of the school. The buses begin stacking at the egress of the drive and then continue
stacking along the loop road, back along the perimeter parking lot drive isle located closest
to the school eventually ending at the tech wing. The perimeter drive within this parking lot
is signed one way requiring vehicles that enter to do so directly into the parking bays. Once
in the lot vehicles have the option of driving approximately 300’ and making a left into an
expanded parking area, making a u-turn and exiting or entering the main loop road, or
continuing straight to the tech wing. The remaining two drive isles within the expanded
parking area are both signed two way. The smaller parking area can also be accessed off of
the perimeter drive approximately 575’ into the site. This parking area is not signed although
by design it appears that vehicles proceed in a one way manner looping around the lot in a
right to left manner. The student lot is also signed one way with the entrance into this lot
being directly in the middle requiring vehicles to make a either a left turn or right turn
immediately upon entering the site. Once in the left hand or right hand parking area, drivers
must continue through in a loop to park or exit.
Emergency vehicle access does not meet current code. Although there is perimeter access
around the front and eastern side of the building there is no access that would meet current
standards for the rear and/or western side of the building and/or site.
Consideration should be given to creating a safer environment for vehicles and pedestrian
traffic, while also separating the bus traffic from the main vehicular traffic. In addition,
complete perimeter emergency vehicle access should be added to allow for fire vehicles to
access the building and ambulances to access any of the outdoor sports fields.
1.3
Zoning Information
The school property is currently zoned R-5, single family residential. The properties
surrounding the school site to the north, south, east and west are also zoned R-5. The

Site Topography
The site topography generally slopes away from the building in all directions. The building
floor elevations vary between 63.5+ at the main building, to 62.25+ at the media center, to
60.9+ at the tech wing (approximate elevations adjusted to NAD 83). Elevations along the
front (south) of the building range from 63.0+ to and elevation of 56.0+ within Robinson
road with slopes between 0.5% - 2.5%. Elevations along the parking side (east) of the
building range from 62.0+ to an elevation of 46.0+ behind the existing basketball courts.
Slopes within both the staff parking lot and student parking adjacent to the basketball court
are at 1.5% with slopes of 5.0% - 20% in the wooded areas surrounding the basketball
court and associated parking. Elevations at the rear (north) of the building range from
62.0+ to an elevation of 30.0+ located in the forested (outfall) area east of the existing
grassed ball fields with slopes ranging from 1.5% - 20%. Elevations along the track side
(west) of the building range from 63.0+ to an elevation of 54.0+ along the far corner of the
property adjacent the track. In general terms the site was essentially constructed with three
distinct plateaus. The first containing the school, associated parking and grassed ball field,
the second containing the baseball and softball fields and the third containing all of the
remaining sports fields.

LEGEND WATER SEWER STORM GAS ELECTRIC 1.6
Utilities
Water
The site is currently served by a 6” public water line with two fire hydrants located along the
front of the school. One hydrant is located adjacent to the drop off loop road and
gymnasium and the other adjacent to the student parking and grassed ball field. The 6”
waterline is served via an 8” line located within Robinson Road and the meter is located
within the grassed area between the drop off loop and Robinson Road. A smaller water line
tapped from the main building also serves the concession building located adjacent to the
stadium and all of the natural turf fields are irrigated. Any new construction will most likely
require the existing system to be looped around the building and additional fire hydrants
installed to meet current fire code.
Sanitary Sewer
The site is currently served by a public gravity sanitary sewer system. There is a small 6”
gravity line that leaves the building adjacent to the existing cafeteria. Based on our review
of the as-built documents it appears that this line was installed in 1982 and serves the
existing kitchen. This line connects into a manhole located within Robinson Road. The
remainder of the building is served by a gravity system with lines ranging from 6” to 8” and
leaving the building at various points around the building. All of these lines eventually tie
into an existing 8” public line that is buried under the school’s grassed multi-purpose fields.
Page 14 of 112
Feasibility Study
The public line enters the site off of Cottonwood Road adjacent to the existing tennis courts,
it then turns and heads in an easterly direction under the fields and then exits the site in the
wooded area north of the existing baseball field. It should be pointed out that the site was
initially served by a private septic system. As-built documents indicate that an existing
50,000 gallon septic tank was abandoned in place behind the school. The school’s original
septic fields were located in the area that is now utilized for the three multi-purpose fields.
Storm Drains
The site is currently served by a closed storm drain
system. Storm drain pipe sizes range from 6” to 48”.
The site is split into two distinct drainage areas. The
first drainage area is approximately 12+ acres and
contains a large portion of the building including
everything with the exception of the rear classroom
and tech wing, the student parking area, main loop
drive and entry. Stormwater within this drainage
area is conveyed in a southerly direction offsite into
a system located within Robinson Road. The second
and much larger drainage area contains the
remainder of the building and site. These areas include the rear classroom and tech wing,
the faculty and visitor parking lots, the stadium, tennis courts and all of the sports fields. A
public storm drain system was installed through the site in the 1970’s; this 48” storm drain is
located under the three existing grassed multi-purpose fields and picks up all of the drainage
area mentioned above in addition to portions of Benfield Road and a majority of the Severna
Gardens subdivision. The total drainage area being conveyed through this public system is
approximately 60 to 80 acres. The outfall for this system is located within the forested area
east of the grassed multi-purpose fields. During our field review which occurred on a warm
sunny day with little to no rain preceding, a constant flow of water was noted exiting the 48”
pipe at the outfall. Based on the level of scouring noted on the concrete it appears that this
flow remains constant and has done so for many years. A request has been made to have
the existing 48” pipe investigated via scoping and video tape in an attempt to determine the
source of the water flow.
Gas, Electric, Cable, Telephone
The site is served via a 3” gas line which enters the site from Benfield Road, traverses the
student parking lot and grass field and then enters the building in the courtyard between the
existing gymnasium and media center. During our field investigation several old gas valves
were noted along with a very large vault. Based on our discussions with the building
superintendant while on site it was unclear whether the meter is located in the vault or
inside the boiler room.
Electric enters the site at the far southeast corner of the property nearest to the visitor
parking. The electric is overhead to a pole located near the entrance to the secondary
parking area located adjacent to the basketball courts. From this pole the electric service is
underground through the faculty parking lot to the east side of the building. See the
mechanical, electrical section of this report for additional information regarding the gas,
electric, cable and telephone.

Feasibility Study
Stormwater Management
Although on site construction has occurred at various points since the school was initially
constructed the site does not contain any stormwater management facilities. A large pond
does exist north of the site adjacent to Thomas Way in the subdivision known as Cool Pond.
This facility was constructed in the early 1980’s and should account for stormwater quantity
management for the large drainage area discussed above. The drainage area to this facility
which traverses the site is a total of 116 acres.
Any new construction that occurs will be required to meet the requirements established by
the Stormwater Act of 2007. These guidelines establish a process by which new
construction needs to utilize sustainable or environmental site design (ESD) to the maximum
extent possible to satisfy water quality requirements. ESD’s include but are not limited to
micro-bioretention, dry and/or wet swales, rain gardens, etc. Attempts should be made to
provide for impervious disconnects and to allow for adequate open space to construct
multiple smaller facilities throughout the site to satisfy these requirements. Based on our
preliminary review of the soils information it appears that infiltration of stormwater should
be achievable on site and cursory conceptual layouts have been reviewed to provide areas
for ESD’s to the maximum extent possible.
1.8
Floodplains, Wetlands and Waterways
The site is not located within the 100 year floodplain as delineated on FEMA flood insurance
rate map 240008-0020-C. The site is located in zone C which means an area of minimal
flooding. A review of NWI mapping indicates the headwaters of a wetland area which is
located within the forested area north of the existing baseball field.
In addition to the continuous flow of water noted in the existing storm drain section of this
report additional discussions have occurred during the committee meetings which also
indicate wet areas during various times along the north side of the site in the vicinity of the
existing grass multipurpose fields, tennis court and track. Additional historical as-built
documentation review performed did not indicate any previous wetland, underground
stream, etc.
A request has been issued to have the Maintenance Department scope and video the
existing storm drain line in an attempt to further determine the source of the water. An
environmental features assessment and if required, wetland delineation should be performed
at the early stage of design of the project.
1.9
Landscape, Trees and Forest Conservation
Landscaping throughout the site consists of lawn and sporadic planting. The planting areas
are mainly concentrated at the front of the school within the open space located between
Robinson Road and the main loop road in addition to an area located between the rear of
the classroom wing and the tech wing. Plantings in both of these areas consist of mature
deciduous trees, several of which are very large. The western and northern sides of the site
Page 16 of 112
Feasibility Study
are heavily buffered from the adjoining residential homes by a combination of evergreens
and deciduous trees. Areas north of the existing baseball field are heavily wooded and lead
to the County owned property (Jennings Road Recreational Area) and portions of the site
around the existing basketball court and small parking lot are also wooded.
There are no documented forest conservation easements on site. Any construction
exceeding 40,000 SF will require compliance with the Maryland Forest Conservation Act. A
forest stand delineation should be completed at the beginning of the design phase of the
project to determine the quality of all on site forested areas and to determine if any of the
mature trees qualify as specimen trees. During this time a forest conservation worksheet
should be completed to more adequately determine the forest conservation acreage required
based on the construction option chosen. On site afforestation may likely be required and
could possibly be met at various locations on site. If it is determined that the selected
construction option chosen will not allow for adequate on site afforestation then a fee in lieu
to the County will be required to meet these regulations.
1.10
Site Entrance
There are two entry drives into the site. One
entry point is a signalized intersection at the
convergence of Benfield Road, Evergreen
Road and Robinson Road. This entry allows
for access into the main student parking lot
located west of the building and 700’+ from
the building’s main entry. The second entry
point is 1000’+ easterly heading towards
Governor Ritchie Highway (Maryland Route 2)
and is 300’+ from the building’s main entry.
This entrance allows for access to the
remaining parking (faculty, visitor and
student) in addition to access for the bus
drop off. A loop road is located approximately
100’ into the site that parallels the building as
it heads to the west; the loop road is 650’+
long and allow for egress of the bus traffic.
1.11
Practice Fields /Athletic Fields / Athletic Courts
The stadium track/field is located at the far western corner of the property. The stadium
field was upgraded to artificial turf in 2008. Lighting around the stadium field is very
outdated. It also appears that the bleachers were recently upgraded, although the seating
on the visitor side is much larger than the home side. There are currently 8 tennis courts
located immediately behind the stadium field. The school’s practice field is located between
the school building and stadium field adjacent to the student parking. There are 3 natural
turf multi-purpose fields located east of the tennis courts immediately behind the building.
The school’s baseball field and softball field are located along the east side of the building on

County owned property and neither
of these fields is lighted. The
basketball courts consist of three full
courts which are located east of the
main parking lot. The court paving
and fencing around the courts is in
poor condition. The school also has
a fenced area for child development
measuring approximately 100’ x 85’
which is located along the side of the

Roof:
The existing roofing is a 4-ply built-up membrane with
aluminum coating on tapered insulation which was
installed in 2000. The overall condition is generally
good although there are existing leaks at various
penetrations. Coping appears to be in good condition.
Replacement of the roofing will be required within five
years.
Exterior Walls:
The original building and additions are brick veneer
on concrete block backup. There is no cavity or
insulation in the walls of the original building. Seals
around stucco panels that replaced original windows
have allowed water to penetrate the envelope in a
significant amount of area. This continuous water
penetration has resulted in failing cast stone sills,
rusting shelve angles, and deterioration of mortar.
Repair of these items is critical. Emergency egress
panels within the in-filled area are located in each
classroom.

Structural System
Severna Park High School is a one/two story structure comprised of a variety of structural
framing systems, including steel frame, cast in place concrete, load bearing masonry, open
web steel joists, and precast plank.
Existing structural drawings for the original building are dated 1957 with subsequent
additions or renovations in 1971, 1982, 1996, 1997 and 2003. Existing structural drawings
indicate that the structure was designed for a roof live load of 30 pounds per square foot.
The 1971 structure classrooms were designed for a live load of 50 pounds per square foot,
corridors for a live load of 75 pounds per square foot and toilet for a live load of 50 pounds
per square foot. The 1971 and 1982 additions were designed for a floor live load of 100
pounds per square foot.
The building is supported by a shallow spread footing foundation system, designed for an
allowable bearing pressure of 4000 pounds per square foot for 1957 building and an
allowable soil bearing pressure for 1971 and 1982 are not available on the drawings.

Existing Conditions
Based on our limited visual observations, the existing structure appears to be in a good
condition.
Observations of the underside of the gypsum roof decks were made in a limited number of
areas. In all instances the deck appeared to be in good condition. It should be noted
however, that AACPS’s experience at other schools undergoing re-roofing or major
renovations has uncovered areas of gypsum roof decks that have deteriorated due to water
infiltration requiring replacement of the deck. The same unforeseen condition is possible
here.
The masonry load bearing walls appear to be in good condition. There were spalling,
cracking, exposed joint reinforcement and loose mortar joints observed at the brick veneer
and window sill at various locations (Photos 1, 2 & 3). In addition, cracks in the terrazzo
floor were observed at the cafeteria and adjacent corridor floor (Photo 4), but not in other
corridor floors. Also, observed settlement at the plaza level pavement, loose rails and
spalling at the retaining walls outside the Gymnasium (Photos 5 & 6).
A lack of an overflow drain or scupper at small area of Part-C roof was observed. In addition,
at the basement mechanical room, leakage was observed through the metal hatch located at
the ground level.
All in all, we found the structure to be in a good condition. Based on our visual observations,
which were limited to those areas that were accessible, we saw no indications of anything
that would cause any concern with respect to the structural integrity of the structure. The
building appears to be structurally sound.

Mechanical Systems
2.4.1 History of Mechanical System Installations and Retrofits
The original drawings for the building were completed in 1957. The original HVAC design for
the building was a central heating plant of three boilers supplying hot water to convectors
and unit ventilators throughout the building. Offices were heated with wall to wall
convectors and classrooms were heated and ventilated with unit ventilators. Piping to units
is located in crawl spaces below the first floor. Toilet rooms and storage areas are
exhausted by powered roof fans. Upper floor corridors were ventilated by gravity roof
ventilators. Shop classrooms and arts and crafts classrooms were located on the upper
floors and ventilated by powered roof fans located directly above the space.
In 1971 additions were made to the building. These included a mini gym and support
spaces for the main gymnasium in Area A, a new media center building in Area G, and
additional administrative spaces in area B. The new gymnasium areas are heated by central
station heating-ventilating air handling units. The administrative area is heated and cooled
by three roof top gas fired/packaged DX multi-zone units. Perimeter areas of the
administrative section are heated with convectors on the wall. Incremental conditioners
were installed on the stage support areas. Many classrooms had unit ventilators removed
and new incremental conditioners installed. In the basement of the media center building a
water cooled chiller connected to a cooling tower outside the building and constant volume
terminal reheat air systems were installed. These provide heating and cooling to both floors
on the media center and supporting rooms. The perimeter areas of the building had
convectors to provide additional heating. During these renovations boiler #2 and #3 were
replaced.
In 1993 many of the unit ventilators were replaced. Two of the new unit ventilators (in the
Management and Foods Classrooms) were ceiling mounted horizontal units with split new
roof mounted condensing units.
In 1996 the roof top units on the administrative portion of the building were removed along
with much of the associated ductwork and replaced with new rooftop units. The unit
ventilators for the painting classrooms and the P.E. classroom were also removed and
replaced with new incremental units. All incremental units in the classrooms of Area B were
replaced. The air handling units serving the auditorium were designed to be replaced;
however, it appears that this did not occur since the original design remained when the air
system was reconfigured later. Unit ventilators in the surrounding music rooms were
replaced. The existing cooling tower and chiller were removed and replaced.
In 1982 a cafeteria expansion occurred; a new packaged gas fired DX cool rooftop unit was
installed at this time. There is no mechanical documentation for this period.
In 1997 the science classroom area was renovated, the incremental units were removed,
two new packaged constant volume roof top units with duct mounted hot water heating
coils, and several split systems were installed.
Page 26 of 112
Feasibility Study
In 2000 boilers #1, #2, #3 were removed and replaced by two new boilers. All pumps in
the boiler room were replaced as well as the expansion tanks.
In 2002 the kitchen hood was replaced and a new hood, fan, and make-up air unit was
installed.
In 2003 the mechanical equipment serving the auditorium was removed. Two new energy
recovery units with heat recovery wheels were installed to serve auditorium.
2.4.2 Heating Water
Description:
The majority of the building is heated from the
hydronic heating water system. Two nominal 500
horsepower fire tube boilers exist in the boiler
room. The current boilers were installed in 2000
and are the third set of boilers since the original
plant construction in 1957. The boilers are dual fuel
and can be fired on #2 fuel oil or natural gas. We
are unsure if the school is utilizing an interruptible
natural gas service in order to capitalize on the dual
fuel capability of the boilers.
The heating water is circulated through 20
individual heating water zone pump systems. The
portion of the heating water system which services
Area G of the building utilizes a primary-secondary
pumping arrangement. 16 of the 21 pumps were
replaced in the year 2000. The pumps that were not
replaced are all located in Area G and date back to
the original 1971 construction.
The major portions of the heating water piping
system were constructed with the original building
in 1957 and the major addition of 1971. Some runouts have been replaced with the replacement of
the terminal units throughout the years. However,
the majority of the piping is 53 years old with the
next largest portion being 39 years old.
Dual Fuel Fired Boilers
Fuel Oil Pump & Controls
The expansion tanks were replaced in 2000 during
the boiler replacement. All the hydronic specialties
which are not directly attached to the 16 replaced
pumps are original.
2.4.2.1 Condition:
The boilers and the pumps in the boiler room are
relatively new and appear to be in good condition.
The pumps in the Area G mechanical room are

Feasibility Study
operating but are aged significantly beyond their
rated useful life. The condition of the piping is
unknown; however, the majority of the heating
water piping in the building has exceeded its rated
useful life.
2.4.2.2 Efficiency:
Boilers: Fire tube boilers were once considered
highly efficient but have been exceeded by modern
condensing type boilers. While rugged, these
boilers have a maximum efficiency of 85%.
Condensing type boilers can reach operating
efficiencies of 95%+ (if operating in the
condensing water temperature range).
Pumping Systems: The pumping systems are all
constant volume and thus are inefficient. The
pumps operate with a constant energy draw
circulating a constant flow rate regardless of the
heating load. Modern energy efficient hydronic
systems utilize variable flow with variable
frequency pump drives. The use of the constant
flow arrangement should be discontinued.
2.4.2.3 Recommendation:
The hydronic heating system is subservient to
overall HVAC system configurations. The two
boilers have 15 years of remaining rated useful
life. The selection of a replacement HVAC system
should not focus solely on reuse of these boilers
since there are higher efficiency heating
alternatives. The reuse of the boilers should be
considered in one of the four HVAC system options
that would be studied in a life cycle cost analysis.
However, these boilers may be more valuable
being relocated to another school in need of a
boiler retrofit rather than their reuse at this facility.
Continued long term reuse of the original 1957
piping should be avoided unless the condition of
the piping can be documented through destructive
testing; and even in that case only the largest sizes
should be reused. Reuse of any of the year 2000
replacement pumps should be dependent upon an
overall HVAC system selection and the pumps
capacity.

Feasibility Study
2.4.3 Chilled Water
2.4.3.1 Description: Area G of the building, the Media
Center Addition, utilizes a chilled water system
consisting of a 275 ton Carrier water cooled
centrifugal chiller, a single frame mounted end
suction chilled water pump and condenser water
pump, and an induced draft cross flow cooling
tower located in a pit in the court yard. The
cooling tower is has a masonry screening wall
installed on three sides, but a large non-masonry
access area on one side. The tower is not
provided with any attenuation features. The
result is that mechanical noise from the cooling
tower can be heard in the court yard and is very
disruptive. The Area G mechanical room is
provided with a refrigerant leak detection and
evacuation exhaust system per ASHRAE
Standard 15.
2.4.3.2 Condition: The chiller, pumps, and cooling tower
were all replaced in 1996. All appear to be in
good working order. The chiller has 9 years of
remaining rated useful life. The cooling tower
and pumps have 6 years of remaining rated
useful life. The cooling tower lacks proper sound
attenuation. The requisite emergency breathing
apparatus associated with the refrigerant leak
detection system has been removed from the
site; its absence is a life safety hazard.
2.4.3.3 Efficiency:
The chiller itself is reasonably
efficient (although not highly efficient); however,
the system as a whole is inefficient for its class.
The primary issue is that the system design does
not address efficiency at partial cooling load
conditions. The chilled water pump is constant
flow and the cooling tower fan is constant
volume. The system lacks the capacity to reduce
pumping energy and cooling tower fan energy as
is typical for current chilled water system
designs. If the system is to remain in place, as a
minimum it should be retrofitted with two way
control valves on the chilled water coils, and a
variable frequency drive (with associated
controls) on the chilled water pump and cooling
tower fan.

Page 29 of 112
Feasibility Study
2.4.3.4 Recommendation: This chilled water system
services a relatively small portion of the overall
building. A full building HVAC retrofit should
utilize a one system type of the majority of the
building. Thus while a chilled water system may
be a viable solution for the overall building; this
chiller and cooling tower in their current
configuration are too small - the system should
be completely reconfigured. It may be possible
to relocate this chiller to a new central chilled
water plant and use this machine in conjunction
with additional chillers. The cooling tower is not
well located and creates acoustical problems in
the court yard; a new cooling tower location for
a much larger plant (under a chilled water plant
study option) should be considered.
2.4.4 Classroom Incremental Units
2.4.4.1 Description: The majority of the classrooms are
conditioned by self contained incremental cooling
units. These units are DX cooling and utilize hot
water heating coils. Each unit is provided with a
large through the wall louver which draws air
into the condensing section for heat rejection
and also exhausts this same air. In addition, a
portion of the louver is dedicated to outside
ventilation air intake. The units installed in Areas
C, D, and E are currently 17 years old and have
exceeded their rated useful life of 15 years. The
units installed in Area B are 14 years old and will
reach the end of their rated useful life in one
year.
Cooling Tower. Noise Enters Court Yard
Through Chain Link Fence.
A Typical Classroom Incremental Unit
The units do not appear to be classroom unit
ventilator grade in that they appear to lack an
air side economizer. Each unit was designed for
an outside ventilation air supply of 250 CFM
which is significantly below the current standard
of 465 CFM per classroom (based upon
occupancy of 30 students and one teacher at a
rate of 15 CFM of outside air per person).
2.4.4.2 Condition: The classroom incremental units are
generally in poor condition. The installation
method of the retrofit installation of the through
wall louver is problematic on multiple fronts; it is
Page 30 of 112

Feasibility Study
unsightly, and is a source of water infiltration
into the building. A majority of the units have
exceeded their rated useful life and are
experiencing failures, including compressors and
fans. The maintenance staff report that the
parts for condenser fans are long lead items.
During our walk through inspection of the
building we found many units which were either
inoperable or operating at a significantly reduced
capacity. By nature self contained DX cooling
units provide poor relative humidity control at
partial cooling load conditions. The units have a
compressor, evaporator fan, and condenser fan
all contained within one housing with little
opportunity for sound attenuation; the result is a
relatively high background noise level (above
classroom NC target levels).
2.4.4.3 Efficiency: In terms of cooling, the classroom
incremental units are particularly inefficient. This
type of unit is not used in modern high
performance educational facilities.

Louver. Note That Rain Easily Penetrates
the Louver.
2.4.4.4 Recommendation: The units should be removed
and replaced with a modern classroom HVAC
system.
2.4.5 Constant Volume Terminal Reheat Air
Systems
2.4.5.1 Description: The spaces of Area G, including the
Media center, are provided with HVAC service
from a constant volume reheat system. The
system is comprised of five constant volume
central station type air handling units, four of
which utilize separate centrifugal return fans.
Each air handling unit has a hot water heating
coil and chilled water cooling coil. The design
drawings indicate that these units provide a
discharge air temperature of approximately 55
degrees. Each individual temperature control
zone is provided with a constant volume reheat
box with a heating water coil and a space
thermostat. In the cooling mode, once the space
temperature is satisfied the supply air is
reheated to prevent overcooling of the zone.
This obviously is an inefficient method of space
temperature control. There does not appear to
One of the Constant Volume Terminal
Reheat System Air Handling Units.

Feasibility Study
be a discriminator control, which would allow for
the discharge air temperature set point to be
reset upward matching the critical zone cooling
load, thus reducing the required reheat energy
load.
2.4.5.2 Condition:
The air handling units are
approaching 40 years old and have exceeded
their rated useful life of 25 years.
The
maintenance staff report that the units have
faulty outside air dampers which tend to cause
coil freezing damage to the water coils. They
report that the fan bearings are in relatively good
condition; however, the overall unit condition
appears to be marginal, with some units missing
panels and shields.
A Return Fan for a Constant Volume
Terminal Reheat Air System
2.4.5.3 Efficiency:
This system type requires the
reheating of air which has been mechanically
cooled in order to prevent over-cooling of
spaces. This is a highly inefficient means of
temperature control.
This system should be
removed and replaced with a modern
educational HVAC system.
2.4.6 Multi-zone Air Systems
2.4.6.1 Description: The administration spaces of Area B
are conditioned by forced air multi-zone systems.
Three rooftop gas fired heating and packaged DX
cooling units service this area. Two of the RTU's
(RTU-1 & 3) have eight zones each and RTU-2
has ten zones. Each zone is provided with a
thermostat and dedicated supply air duct
distribution system. Each RTU has a hot deck
and a cold deck. The controls mix air from each
deck using zone dampers to provide a discharge
air temperature that matches the zone heating
or cooling load. The hot deck and cold deck
discharge air temperature set points are typically
reset to match the heating and cooling load
(respectively) of the critical zones (i.e. a
discriminator control sequence). The rooftop
multi-zone units are currently 14 years old and
have one year of remaining rate useful life.
Whereas the cooling side of the units is

Feasibility Study
packaged DX, these units are not highly energy
efficient. However, the areas they service are
broken into many individual temperature control
zones, allowing the system to modulate its
capacity to provide a fairly high level of occupant
comfort control.
2.4.6.2 Condition: The rooftop multizone air handling units have one year of remaining rated useful
life. The maintenance staff has stated that these rooftop units have been experiencing
problems with the condenser fans.
2.4.6.3 Efficiency: We were not able to ascertain the specific KW per ton energy efficiency;
however the scheduled full load amps of these units in comparison with the rated cooling
capacity is higher than expected for packaged rooftop equipment. Given that packaged DX
system are generally not highly efficient, these units should be considered relatively
inefficient.
2.4.6.4 Recommendation: The area serviced by these multizone units should be retrofitted with a
highly efficient HVAC system in coordination with an overall building HVAC retrofit.
2.4.7 Packaged Rooftop Constant Volume
2.4.7.1 Description: Two science classrooms in Area E
are conditioned by dedicated packaged rooftop
DX air conditioning units with duct mounted hot
water heating coils (one unit per classroom).
Each unit is controlled by a space thermostat.
The units do not have a means to modulate their
cooling capacity at partial cooling load conditions
other than cycling the compressor on/off. This
results in high indoor relative humidities at
partial cooling load conditions.
2.4.7.2 Condition: The units were installed in 1997 and
have two years of remaining service life of their
15 year rated useful life. One of the two units
was inoperable at the time of the building
inspection.
Science Classroom Area Packaged Rooftop
Units
2.4.7.3 Efficiency: The packaged DX cooling system is
inefficient.
These units should be
removed and the classrooms should be provided
with a highly efficient educational grade HVAC
system as part of a total building HVAC retrofit.

2.4.8 Split Systems
2.4.8.1 Description: The building is provided with a
variety of split DX cooling systems, primarily
located in the Science classrooms of Area E.
These include: ceiling concealed indoor, vertical
indoor unit ventilator, and horizontal console unit
ventilator units, each with a paired outdoor
condensing unit. Similar to other DX cooling
units, these are relatively inefficient systems with
have difficulty maintaining indoor relatively
target levels at partial cooling load conditions.
Ceiling Mounted Split System Indoor Unit
2.4.8.2 Condition: The units were installed in 1997 and
have two years of remaining service life of their
15 year rated useful life. The systems were in
various states of operating conditions during our
walk though, with one vertical unit spilling
condensate on the floor. Many of the classrooms
serviced by these units were particularly humid
and had buckling ceiling tiles.
2.4.8.3 Efficiency: The packaged DX cooling systems
are inefficient.
These units should be
removed and the classrooms should be provided
with a highly efficient educational grade HVAC
system as part of a total building HVAC retrofit.

2.4.9 Window Air Conditioners
Several areas of the building have been
retrofitted with window air conditioning units.
These are inappropriate for an institutional
building, are noisy, inefficient, and should be
removed. These areas should be provided with
an appropriate educational grade HVAC system.

2.4.10 Hydronic Terminal Heating
2.4.10.1 Description: The building is provided with a
variety of different hydronic terminal heating
units from the original construction of 1957
and 1971. While the majority of the original
1957 hydronic fin tube heating units have been
removed, some other types of units remain.
The remaining unit types from these two
construction periods include: hot water unit
heaters, cabinet unit heaters, and convectors.
2.4.10.2 Condition: Our inspection was conducted
during the summer so we do not have first
hand information on the operating condition of
this equipment. The maintenance personal did
not report any specific system wide problems
with this type of equipment. All of these units
exceeded their rated useful service life decades
ago.
2.4.10.3 Efficiency:
The efficiency of the actual
terminal units depend on the cleanliness of the
heat exchanger; which should be considered
somewhat as it is expected that internal
surfaces of the heat exchanger are coated with
mineral deposits thus diminishing the heat
transfer capacity of the unit. The system
efficiency is also driven by the combustion
efficiency of the boilers.

2.4.11 Heating Ventilating Units
2.4.11.1
Description: The main gymnasium and the mini-gym are conditioned by central station
type heating ventilating units, capable of providing 100% outside air for summer time
ventilation, and mixing return air with outside air for heating season service. Each unit is
provided with a hot water heating water coil, mixing box, and filter bank. These units are
original to the 1957 and 1971 construction and are currently 53 and 39 years old;
dramatically exceeding their rated useful service lives of 25 years. These units do not
provide air conditioning service. While this is typical for many public school gymnasiums,
the mechanical supply of un-dehumidified air into the gymnasiums, which are interior to
the building's vapor barrier envelope, introduces a very large dehumidification load onto
the adjacent air conditioned spaces.
2.4.11.2
Condition: The units are operating but appear to be worn.
2.4.11.3
Efficiency: The motor efficiencies are low compared with modern premium efficiency
motors.
2.4.11.4
Recommendation: Replace these units and consider air conditioning the spaces as a
means to aid in maintaining the overall school relative humidity level.
2.4.12 Ventilation & Exhaust Systems
2.4.12.1
Description: The building uses a distributed ventilation and exhaust approach utilizing
approximately 78 individual exhaust fans; nearly all of which appear to be original to the
1957 and 1971 construction. Ten fans were replaced in 1980. The fans range in age
from 53 to 30 years old.
The most typical ventilation method for the classroom areas is that outdoor ventilation
air is introduced into the building via the classroom incremental units and is transferred
into the corridors where it migrates to exhaust air intake locations, many of these being
exhaust registers in the corridor ceilings. Although this was a common ventilation
method at the time the building was originally constructed, this arrangement poses a
significant life safety threat since the system could mechanically force smoke from a
classroom fire into the means of egress. This air transfer method is not allowed by
modern building codes and should be discontinued.
The building also uses roof gravity ventilators for what appear to be both intake and
pressure relief service.
The crawl space under the first floor is provided with several side wall brick vents for air
inlets and several open end vertical ducts terminating at the roof level with gravity
ventilators for air discharge.
2.4.12.2
Condition: The general duty exhaust fans are all long past their rated useful life and are
in various states of physical condition. The Art Room kiln exhaust hood is too small to
Page 36 of 112
Feasibility Study
cover all three kilns. The brick vents inlets are in various conditions. The crawl space is
very humid. The gravity vents appear to be in working order.
The general configuration of the ventilation system for the typical classrooms poses a life
safety hazard. The stage exceeds 1,000 square feet in area and is required to be
provided with an emergency ventilation system for smoke control (which is missing).
2.4.12.3
Efficiency: This is a passive ventilation system which does not consume energy.
However, there does not appear to be insulation under the floor, thus the ventilation
system induces a heat transfer load on the building.
2.4.12.4
Recommendation: Nearly all exhaust fans should be replaced. A replacement kiln
exhaust hood should be provided of adequate size to cover all three kilns. The brick
vents inlets are in various conditions; these should be replaced as a whole grouping with
heavy duty vents to provide several decades of continued use. The crawl space is very
humid. The gravity vents could remain in place; consideration should be given to
replacing some roof terminals with power roof ventilator type fans to increase the
ventilation in the crawl space. A radon test should be conducted to determine of the
earth is releasing radon gas into the crawl space. The general ventilation system
configuration poses a life safety concern and should be changed. In addition, a
Dedicated Outside Air System (DOAS) should be incorporated to decouple the treatment
of outside air from space conditioning since there is no relationship between these
functions and it is the primary reason for poor indoor air quality). Provide a stage
emergency ventilation system as required by code.
2.4.13 Kitchen Exhaust & Make-up
2.4.13.1
Description: The kitchen is provided with a gas fired make-up air unit and an upblast
grease exhaust type exhaust fan. These units are provided with basic operational
functioning controls. The system is not provided with the heat sensing controls to
automatically energize the exhaust fan when cooking operations occur as is required by
current code.
2.4.13.2
Condition: The units were installed in 2002 and are in good condition. The make-up air
unit has seven years of remaining rated useful life and the upblast exhaust fan has 12
years of remaining rated life.
2.4.13.3
Efficiency: The motor efficiencies are unknown. The gas fired heater is a conventional
80% efficient type, not a high efficiency condensing type unit.
2.4.13.4
Recommendation: This system should remain in place, but be retrofitted with code
compliant controls.

Electrical Systems
2.5.1 Power
Power Distribution:
Electrical service for the building is provided via several
services in different sections of the building. The main service
is provided via a secondary substation located in a vault next
to the boiler room. The power generation company is ‘PEPCO
Energy Services’ and the power distribution company is ‘BGE’.
According to BGE, total of 3 meters/electric services/accounts
exist in the building. Voltage systems used in the building
are 480Y/277V and 208Y/120V. There is a switchboard with
capacity of 3000A located next to the vault in boiler room
area for the main electric service.
Electrical power throughout the building is distributed via high
voltage and low voltage branch panelboards and dry-type
transformers located in several electrical rooms/closets in
different part of the building. Most of the existing
panelboards/equips seems in a good condition and working
properly. Existing main switchboard in main electric room and
some panelboards are old and have a poor condition.

Interior Lighting:
The lighting systems throughout the building are based upon
the original designs. Most of the fixtures are old. The
additions, which were constructed at different times, vary in
lighting design style and fixture selections. The most recent
addition has a design approach which eliminates the
traditional ceiling, paints the underside of the deck above
black, and suspends troffers or pendant fixtures (depending
on the space). There has been some recent luminaire retrofit
activity in which the older T-12 fluorescent lamps and
magnetic ballasts have been replaced by T-8 lamps and
electronic ballasts. Following are the lighting conditions for
some of the areas:

Corridors: mostly 2X4 recessed fixtures with
fluorescent lamps are used. Many of these fixtures
have been retrofitted with the T-8 lamps and
electronic ballasts. These fixtures seem to be in a
good condition.

Classrooms: different fixtures are used. In most
classrooms fixtures are 1X4 surface mounted with
fluorescent lamps. Light fixtures in most of
classrooms are old and are not in a good condition.

Science Labs Addition: Fixtures in this part are
mostly1x4 and 2X4 with fluorescent lamps. This part
of building was renovated recently and light fixtures
in these areas seem in fair condition.

Emergency Lighting and Exit Lights:
Auditorium Lighting
Emergency lighting in different parts of the building are
provided by wall mounted double-head battery pack fixtures
or ceiling fixtures with battery ballasts. Most of recently
renovated areas have ceiling fixtures with battery ballasts for
emergency lighting.
Exit Sign
Page 39 of 112
Feasibility Study
The existing exit lights throughout the building differ in
appearance and lamping depending upon the age of the
given area of the building and whether the fixture is original
or has been replaced. Generally they are single or double
faced, green LED fixtures. The condition of these fixtures in
renovated areas seems fair.
Power for emergency lighting as part of critical loads is
provided by the existing emergency generator.
Exterior Lighting:
Driveway Lighting
Lighting for parking lots and driveways on the site is provided
by exterior fixtures with HID lamps. Fixtures for Parking lot
areas are mounted on high poles with single or double arms.
Lighting in regular driveways is provided by fixtures with
reflector and lens mounted on top of shorter poles. Some
light fixtures and poles are not in a good condition. It seems
the exterior lighting is controlled via time switch.
2.5.2 Fire Alarm System
Parking Lot Lighting
Existing System:
Building has a conventional fire alarm system with multiple
control panels from manufacturers such as Simplex and
Notifier. Fire alarm control panels are located in different part
of the building. There are 2 main fire alarm annunciator
panels (FAAP) which are located in front of reception area in
the entrance lobby. Both have graphic faceplates showing
building floor plans.
Initiation Devices:
Fire Alarm Control Panel
Fire alarm Pull boxes provided at exit doors. Smoke detectors
installed in some areas of corridors and some classrooms. No

recent years. Existing system includes central control by
TELECOR II, ceiling speakers mostly in corridors, media
center and cafeteria and wall speakers in classrooms and
gymnasium. Call stations are provided in all classrooms. Wall
mounted volume control switches are installed mostly in
office areas. Existing PA system seems generally in fair
condition. Protection cover on some speakers in gymnasium
is broken. Speakers in classrooms are not in a good condition.

2.5.4 Data & Wireless Systems
There are 2 server rooms in school. Each includes data racks
and wireless devices. Small size UPS units are provided to
feed data equipment. Data outlets are provided in
classrooms, most of offices and media center. As part of
science lab addition, complete data network is installed for all
locations in this part of building. Air conditioning systems in
both existing server rooms are not working properly.

2.5.5 Security System
There is an existing security system in school. Existing
security system includes security control panel, security
cameras, motion sensors and other initiation and notification
devices. For outdoor security, wall mounted cameras are
installed outside the building. Also security lighting via wall
mounted outdoor type light fixtures with HID lamps is
provided at the perimeter walls of the building. Inside the
building motion detectors are provided mostly in corridors.
Other security devices are provided in other locations
throughout the building. Security system coverage
throughout the building and system operation needs to be
verified.

2.5.6 Grounding and Lightning Protection System
Existing grounding system includes main building grounding
electrodes, main grounding terminal and ground terminals in
several locations in the building. It appears grounding
conductors and bonding are provided for all panelboards and
equipment.
Existing lightning protection system consists of air terminals
at the roof around the building and related bonded copper
conductors. While the air terminals and bonding to copper
conductors at the roof is visible from grade, the balance of Lightning Protection Air Terminal
the system is concealed. Normally the conductors are
connected to the ground via grounding electrodes.
Regarding the age of the system, complete verification of
both systems including all devices and connections necessary
tests and measurement seems necessary.

EXISTING CONDITIONS
2.6
Plumbing Systems
The building is served by the County water system. The existing 8" water main enters the
front of the site through a meter vault and distributes to two hydrants at the front of the
building. The sprinkler service enters the front of the building at the west end of the
administration wing where an existing water room is located.
The domestic hot water is generated by circulating heating water from the boilers though
tubes of a shell and tube heat exchanger which heats water in the shell of the heat
exchanger. The domestic hot water is drawn out of a large horizontal storage tank through the shell - and back to the tank by in-line circulator pumps. The tank is insulated
and we were not able to locate a nameplate with a size; however, we estimate that the tank
stores approximately 2,500 gallons. The age and capacity of the system is unknown (it was
not documented on the available materials). Natural gas fired water heaters were added in
parallel during the renovation of the science wing in 1997; thus allowing the boilers to be
shut down at the end of the heating season. This installation does not meet current code
requirements. The equipment needs to be modified or replaced and appropriate tempering
valves added to provide tepid water.
Plumbing fixtures all appear to be original or dated and beyond their useful life. The water
closets are floor-mounted, urinals are floor and wall-mounted, and lavatories are individual
wall hung type. Plumbing fixtures no longer meet code requirements for water usage and
are not properly configured for ADA accessibility.
The building has a crawl space throughout, which accommodates accessibility to distribution
and drainage piping for repair, inspection, and replacement. The existing exposed piping in
the crawl spaces can be inspected to determine its condition, allowing significant savings if it
is determined that the piping is in fair to good condition. Since this piping is accessible, a
decision to delay replacement even if only for 5-10 years is not critical because this piping
can be easily replaced. Based on the age of the original building and additions, the existing
water distribution system should be tested for lead content. If tests conclude that lead is
present in unacceptable levels, then the distribution system should be replaced in its
entirety.
Due to the age of the installed plumbing lines, it will be necessary to cut out sections of
sanitary, domestic cold and domestic hot water lines in several locations in the subbasement, and inspect this piping for scale and/or corrosion. The inspection results will
contribute to deciding the scope of piping replacement required during a building
renovation/modernization program.
Minimum recommended actions include:
1.
Replace all domestic water, sanitary and storm piping located outside of existing
crawl spaces.
2.
Replace all plumbing fixtures. New plumbing fixtures will be installed with provisions
for ADA accessibility.
Page 43 of 112

2.7
Feasibility Study
The existing sanitary and storm water piping within the crawl space will be utilized
where deemed possible. All risers and branches to new fixture layouts will be new
piping.
New modular high efficiency gas-fired water heaters should be installed. This
domestic water heating system will serve the entire building and will be equipped
with hot water circulators, expansion tank, and tempering valves as required.
Fire Protection System
The building currently is not protected by a full coverage fire sprinkler system. The media
wing and portions of the existing administration wing are protected with automatic fire
sprinklers. If the school is revitalized, modernized, or replaced, a full coverage sprinkler
system will need to be installed in order for the building to be code compliant. The existing
water service is adequate for flow to supply a sprinkler system; however, a fire pump will
need to be added to boost the pressure for distribution to the extremities of the building. An
alternative to the fire pump may be to feed the site from another section of the grid which
would divide the flow and thereby increase pressure available by reducing pressure drop to
the site during flow conditions. This option should be evaluated by the civil engineer for
feasibility.
Recommended minimum actions include:
1.
Provide a fire pump to boost pressure to the building. The sprinkler service and all
zone valves will be located in a new fire pump room.
2.
Extend systems to all parts of the building for a fully sprinklered facility in
accordance with all applicable NFPA standards. Multiple sprinkler zones will be
provided for the building.
3.
The sprinkler system will be hydraulically designed to minimize pipe size
requirements and to provide an economical distribution system for the building.

CODE ANALYSIS
Accessibility Evaluation:
The existing school is generally accessible in that an accessible ramp at the main entry permits
public access into the school and an elevator installed with the 1971 addition makes the second floor
generally accessible. It was noted that the public entrance to gymnasium is not accessible as there
are exterior steps and no accessible ramp.
A general examination of the existing school found the following areas to be deficient. All must be
further reviewed and addressed during the schematic design phase of this project:
 Accessible entry and exits to and from the school must be added.
 Toilet rooms and stalls must be made accessible, including all plumbing equipment.
 Required clearances at some doors may not be adequate for accessibility.
 Door hardware must generally be replaced with accessible door hardware.
 Height of all pull stations, switches and signage does not comply, and must be fixed.
 Classroom and other public space entries must be reviewed for ADA compliance.
 All egress door swings and clearances must be reviewed and brought into compliance.
 Door closers must be tested, so that force required to open doors is compliant.
 Assistive listening devices will be required in public spaces.
 ADA compliant signage will be required.
Building/Life Safety Code Evaluations:
The existing school is a mixture of concrete masonry bearing wall and steel frame construction types
totaling 296,191 GSF. Only a portion of the building is currently sprinklered. These areas include the
1971 additions of the media center and administration offices. The building can be classified as Type
2C (non-combustible/unprotected) construction in accordance with the 2006 IBC code. The
occupancy classification is Mixed Use, including Educational and Assembly type occupancies. Both of
these classifications must be confirmed with the Anne Arundel County code officials during
schematic design if the Board of Education selects to move forward with either Revitalization or
Modernization.
The existing school is currently non-compliant in terms of area allowed. In the options including
Code Upgrade work, an automatic fire sprinkler system would be added. This will result in the
allowable area limitation being increased. However, given the size of the existing building and the
additions proposed in both the Revitalization and Modernization options, the building will still exceed
the increased area limitations requiring the building be divided into separate fire areas. The
additions will have to be separated from the existing building with a fire wall, making them entirely
separate buildings from a code standpoint.
Special considerations should be given to the following code concerns in future phases:
 The fire alarm system will require upgrading to interface with the new addition(s).
 Assembly uses shall be properly separated from Educational uses.
 Existing Hazardous Materials must be abated.
 Sprinkler system must be installed.
 Fire alarm must be upgraded. Any new fire alarm with the addition must be tied into the
existing system, or the existing system must be replaced.
 Smoke barriers must be installed between the corridors and other spaces.
 A paved fire lane must be installed around the perimeter of the building to enable fire
truck access.

OPTION A: DO NOTHING
Assessment
This is the no-cost option of doing nothing to the existing facility. This option establishes a base line
for comparison to other schemes.
Advantages:
1. School operations will not be disrupted since there will be no construction activities.
Disadvantages:
1. Spatial requirements set forth in the Educational Specifications will not be met by the
existing building.
2. The existing building does not meet current life safety and building codes.
3. The existing building will remain inefficient with regard to energy and water consumption.
4. Maintenance items which have been deferred will remain deferred.
5. Costs will be incurred in the near future to replace many building systems that are reaching,
or are beyond their rated useful lives.
6. Congestion will continue to be an issue in the main corridor during lunch periods and at
dismissal.
7. Bus traffic and parent drop off traffic will remain in conflict.
Page 47 of 112
Feasibility Study
OPTION B: PATCH AND PAINT
ASSESSMENT
This option provides for a minimal repair and painting of the existing facility, incorporating minor
repairs to systems and construction to provide continuing service for the foreseeable future. No
significant changes to the existing structure will be made to conform to the proposed Educational
Specification or to address building and life safety concerns.
Advantages:
1. Most of this work will be completed during summer break and after hours so school operations
will be minimally disrupted.
2. Deferred maintenance items will be prioritized and completed as the budget allows.
3. Exterior brick veneer will be repaired.
4. Interior finishes will be repaired and in some cases replaced.
5. There is no loss of use of the existing stadium and play fields.
Disadvantages:
1. The existing facility falls short of meeting the program, area, and adjacency requirements of the
Educational Specifications.
2. Indoor air quality and comfort will remain inadequate as the existing distribution system will not
be upgraded to meet current standards.
3. Existing window systems will remain and continue to provide only minimal amounts of daylight
in the classrooms
4. Exterior walls will remain uninsulated, thus the thermal performance will continue to be poor in
relation to a new facility and energy consumption will not be improved.
5. Accessibility, building, and life safety code upgrades will not occur. The majority of the building
will remain unprotected by an automatic fire sprinkler system.
6. Costs will be incurred in the near future to replace many building systems that are reaching, or
are beyond their rated useful lives.
ANTICIPATED SCOPE OF WORK
Architectural – Interior
 Existing interior wall finishes will be repaired and painted.
 Floor finishes will be changed out in those spaces where the Educational Specifications call
for a different finish than exists in a space.
 All acoustical ceiling panels will be replaced and the existing suspended metal grid system
will be repainted.
 Interior doors will be refinished. Existing hardware will be repaired where possible. In some
instances, hardware may be replaced.
 Casework in classrooms and offices will be repaired as required.
 Science classroom equipment and fixtures will be replaced as required.

Revitalization of the existing building will reuse most of the existing building though portions will be
demolished to accommodate new additions that are required to meet programmatic requirements of
the Educational Specifications. Spaces within the additions will meet the area requirements of the
Educational Specifications, but rooms in the existing building will not be structurally modified.
Therefore, most classrooms will continue to be either over or under their specified area.

A geotechnical investigation will be conducted during the design phase to determine
foundation recommendations.
If a slab on grade is feasible from a geotechnical standpoint, then a 5” concrete slab on
grade reinforced with welded wire mesh will be considered. Slab on grade will be more cost
effective compared to a framed structure with a crawl space.
However, if the recommendations of the geotechnical report indicate that a slab on grade is
not feasible, and a framed first floor structure be required, 8” precast concrete plank with a
2” lightweight concrete topping slab supported by masonry bearing walls in the crawl space
is a viable option.
Additional deeper foundation walls will likely be required at the juncture of the additions with
the existing to “close off” existing crawl spaces from the backfill.
We anticipate a shallow spread footing foundation system, consistent with the existing
building, will be appropriate. However, this must be confirmed by a geotechnical
investigation.
Mechanical
A. General Overview
The mechanical systems will be designed in compliance with DGS and all industry standards
essentially replacing the entire HVAC system as a means to: bring the system up to current
standards, increase system efficiency, address the user's needs for the next 20+ years, and
improve sustainability. The overall goals of the system retrofit are: provide good indoor air
quality, to be highly energy efficient, to be easily maintainable, to have low first cost as well
as low life cycle costs, and to be cognizant of project construction budget limitations. The
system we are recommending is Active Chilled Beams supplied from Dedicated Outside Air
Systems (DOAS) with a Central Geothermal Water to Water Heat Pump Plant.
B. Ventilation System
The first major component of the proposed overall HVAC system is the Dedicated Outside Air
System (DOAS) which delivers code required outside air directly to the room level. The
purpose of the dedicated ventilation system is to decouple the conditioning of outside air
used for ventilation from the conditioning of room air. The primary advantage of the
decoupling is that the outside air can be properly dehumidified regardless of the sensible
cooling load of the space, assuring improved room relative humidity levels during space
partial cooling load conditions. The use of the DOAS also reduces the operating cost by only
Page 53 of 112
Feasibility Study
Mechanical – continued
requiring the conditioning of the quantity of outside air required to meet the sum of all space
ventilation loads.
C. Overhead Active Chilled Beams
The chilled beam provides heating or cooling on demand on a room by room basis. The unit
has no fan; it uses the induction air principal, driven by ventilation air, to cause 3 to 4 times
the air flow rate of the DOAS ventilation air to be drawn up through the perforated panel in
the center of the chilled beam – across the terminal unit coil – and be discharged with the
DOAS ventilation air out the two linear slot diffusers on the perimeter of the chilled beam.
The hydronic arrangement of the system is four pipe. The chilled beams use the return
chilled water from the DOAS unit.
D. Central Geothermal Water to Water Heat Pump Plant
The main component is a modular water to water heat pump which uses multiple nominal
thirty to seventy ton modules. Each module is an independently controlled (staged) heat
pump capable of producing chilled and hot water. The modular unit as a whole can produce
chilled and heating water simultaneously. The source side of the modular unit is piped to a
geothermal well field which provides a heat source/sink.
E. System Equipment
The system is comprised of:
1. A modular geothermal grade water to water heat pump unit with VME valving using
fifteen 70 ton modules. Basis of design: Multistack
2. Two variable volume frame mounted end suction geothermal well field water pumps with
variable frequency drives.
3. Two variable volume frame mounted end suction heating water pumps with variable
frequency drives. 50 HP
4. Two variable volume frame mounted end suction chilled water pumps with variable
frequency drives, 1,700 GPM, 100 HP.
5. One geothermal well field with approximately 180 wells using a depth of 600 feet, using
1-1/4" SDR-9 in the vertical bore hole and SDR-11 or 15 piping for the horizontals. Wells
to be grouted with high conductivity (1.2) bentonite grout. 3,150 GPM, 100 HP
6. Five 20,000 CFM ERU’s for the DOAS
7. Five 7,500 CFM large space AHU's,
8. Fan coil units for the entry areas (areas subject to very high infiltration loads).
9. A chilled beam(s) for each remaining occupied room. A typical classroom for 30 students
would take three six foot chilled beams.
10. Heating water convectors or hot water unit heaters for restrooms and utility spaces.
11. A DDC Building Management System.
12. Some miscellaneous utility fans (propeller and cabinet type).
Page 54 of 112
Feasibility Study
F. Advantages
Some of the advantages of the chilled beam and modular water to water geothermal heat
pump system include the following:
1. Superior indoor air quality due to:
a. Excellent cooling season relative humidity control.
b. The high ventilation effectiveness due to the characteristics of the induction air
method.
2. The highest degree of zoning with essentially every occupied space being provided with
individual temperature control.
3. Space by space heating or cooling on demand.
4. A reduction in ductwork when compared with a VAV system or ducted water source heat
pump system with DOAS.
5. Very high operating efficiency.
a. Mass energy storage over time for reuse in the building.
b. High efficiency heating and cooling plant at design temperatures (COP = 4+,
EER = 14+). These improve dramatically at partial load conditions due to the
geothermal characteristics.
c. An efficiency improvement from the increased chilled water temperature
difference.
6. While the four pipe system arrangement requires a second piping network inside the
building, the delta Tee of both systems is greater than 500% larger than the first three
options minimizing the cost impact of the additional piping.
7. First cost and maintenance cost savings from the consolidation of all heating and cooling
plant equipment into a single unit. This includes:
a. Savings from centralized compressor maintenance.
b. Savings from the elimination of 85% of the filter maintenance.
8. A first cost and maintenance cost reduction on the electrical power distribution system
associated with the elimination of a water source heat pump unit for each room. This
eliminates: a branch circuit to each unit, several electrical panel boards, a feeder for
each panel board and a switchboard switch for each feeder. Some cost is added back in
for the circuiting to the modular water to water heat pump and extra pumps, however,
all of those units are located immediately adjacent to the main electrical room.
9. Very low background noise levels due to the elimination of a terminal unit fan.

8. Fan coil units for the entry areas (areas subject to very high infiltration loads).
9. A chilled beam(s) for each remaining occupied room. A typical classroom for 30
students would take three six foot chilled beams.
10. Heating water convectors or hot water unit heaters for restrooms and utility spaces.
11. A DDC Building Management System.
12. Some miscellaneous utility fans (propeller and cabinet type).
F. Advantages
Some of the advantages of the chilled beam and modular water to water geothermal heat
pump system include the following:
1. Superior indoor air quality due to:
a. Excellent cooling season relative humidity control.
b. The high ventilation effectiveness due to the characteristics of the induction air
method.
2. The highest degree of zoning with essentially every occupied space being provided with
individual temperature control.
3. Space by space heating or cooling on demand.
4. A reduction in ductwork when compared with a VAV system or ducted water source heat
pump system with DOAS.
5. Very high operating efficiency.
a. Mass energy storage over time for reuse in the building.
b. High efficiency heating and cooling plant at design temperatures (COP = 4+,
EER = 14+). These improve dramatically at partial load conditions due to the
geothermal characteristics.
c. An efficiency improvement from the increased chilled water temperature
difference.
6. While the four pipe system arrangement requires a second piping network inside the
building, the delta Tee of both systems is greater than 500% larger than the first three
options minimizing the cost impact of the additional piping.
7. First cost and maintenance cost savings from the consolidation of all heating and cooling
plant equipment into a single unit. This includes:
a. Savings from centralized compressor maintenance.
b. Savings from the elimination of 85% of the filter maintenance.
8. A first cost and maintenance cost reduction on the electrical power distribution system
associated with the elimination of a water source heat pump unit for each room. This
eliminates: a branch circuit to each unit, several electrical panel boards, a feeder for
each panel board and a switchboard switch for each feeder. Some cost is added back in
for the circuiting to the modular water to water heat pump and extra pumps, however,
all of those units are located immediately adjacent to the main electrical room.
9. Very low background noise levels due to the elimination of a terminal unit fan.

Feasibility Study
APPENDIX E – SUSTAINABLE DESIGN
Replacement options will be registered with the US Green Building Council as a LEED® project and
will pursue LEED® Silver certification (within the range of 50-59 total points). The design will
showcase the incorporation of sustainable techniques and materials. The following outlined
categories follow the divisions of the LEED® for Schools rating system and possible points to
achieve.
1. Sustainable Sites
Integrating building location and sustainable site features will minimize the environmental
impact of buildings on the site. Potential Strategies include:
a. Minimize site disruption, soil erosion, and air pollution associated with construction
activities.
b. Appropriate landscaping for energy conservation.
c. Planting native trees species.
d. Eliminate the use of pesticides in order to promote protection of regional watersheds
e. Examining alternative energy systems such as photovoltaic panels for potential use
as pedestrian walkway shading and weather protection devices in addition to or
instead of roof mounted.
f. No “light pollution” since exterior lighting is installed at a minimum (for safety
requirements) to allow for view of night sky.
g. High albedo roofing to reduce heat island effect.
h. Low-emitting and fuel efficient vehicle parking spots.
2. Water Efficiency
Water harvesting and water conservation are to be implemented.
include:
Potential Strategies
a. Reduce the need for municipally supplied water and carbon cost of treating that
water.
b. Maximize water conservation – students, staff, and community can learn about these
features – educational tool.
i. Eliminate the use of potable water for irrigation.
ii. Low flush toilet fixtures
iii. Low flow aerators for sink faucets
iv. Low flow shower heads
v. Recycled water for mechanical system recharge
vi. Recycle mechanical system condensate.
c. Manage and conserve storm water and reduce storm water runoff
i. Harvesting rainwater for many uses including irrigation.
ii. Designing pervious parking lots and paved surfaces to capture storm water
below paved areas instead of as runoff
iii. Using retention and detention ponds as educational tools
Page 109 of 112
Feasibility Study
3. Energy and Atmosphere
Reduce energy consumption of buildings. Potential Strategies include:
a. Computer energy modeling used to inform the design of the building. Annual energy
savings and yearly operating cost reduction goal should be a minimum of 30% over
the American Society of Heating, Refrigeration and Air-Conditioning Engineers
(ASHRAE) Standard 90.1
b. The building should be zoned and controlled in a way specific to occupancy and use
profiles. These systems will recognize the mass and building characteristics of the
building as well as control logic designed to maximize the return on investment.
c. All building system components selected will be free of chlorofluorocarbons (CFCs)
and hydro chlorofluorocarbons (HCFCs).
d. Daylighting should be present in all classrooms and spaces that are regularly
occupied by students along with intelligent controls of electric lighting that recognize
the amount of useful daylight present in each space.
e. Natural ventilation should be used where possible.
f. Mechanical ventilation should be decoupled from space conditioning to ensure fresh
air and energy recovery independent of space conditioning requirements.
g. The project should incorporate full enhanced building system commissioning to
insure that the design intent will be met.
4. Materials and Resources
Sustainable material choices will reduce use of virgin materials within the building. Potential
Strategies:
a. Storage and collection of recyclable materials within the school.
b. Divert a minimum of 75% of the materials during demolition and construction from
the landfills through recycling or salvaging.
c. Using new construction materials that have a significant percentage of recycled
content.
d. Using materials that are harvested, extracted, and manufactured within a 500 mile
radius of the project site
e. All wood products used on the project are Forest Stewardship Council (FSC) certified
products.
5. Indoor Environmental Quality (IEQ)
Reducing levels of contaminants, increasing filtered outside air and ventilation, and
monitoring humidity all contribute to a more desirable indoor air quality. Potential strategies
include:
a. Smoke free school zone.
b. Classroom spaces will meet a certain STC rating for acoustics - increased insulation,
seals and special acoustic ceiling tiles for better communication between teachers
and students.
c. Low emitting materials including adhesives & sealants, paints & coatings, flooring
systems, agrifiber products, furniture, and ceiling & wall systems.

d. Appropriate ventilation and elimination of chemicals and pollutants such as copy
machines and tracked-in dirt from the exterior.
e. Use outdoor spaces as instructional areas giving students the opportunity for fresh
air during the day.
f. Carbon dioxide (CO2) monitors that inform the building controls to insure adequate
amounts of ventilation where and when needed.
g. Designing electric lights to take advantage of natural light in spaces.
h. A mold free environment.
i. The building additions and renovations or new construction implementing the use of
daylight and views throughout.
j. Individual temperature regulation of rooms to provide adequate comfort for all
occupants.
6. Innovation in Design
Incorporating innovative techniques that are unique to SPHS and setting a precedent for
other LEED school projects in the future. One potential example of an innovation credit for
this project would be:
a. Green housekeeping plan for the school – use of non-toxic cleaning and maintenance
products and environmentally friendly practices.
7. Regional Priority
Severna Park and surrounding Anne Arundel County areas potentially have materials or
regional differences that could result in achieving specific Regional Priority credits. More
research will be done to determine what sets the area apart and where we could achieve
these additional credits.
8. The school as a teaching tool
The school building can be used and incorporated as part of the school day curriculum.
Students will take part in recognizing how the building works and why the various
sustainable features of the building are important for understanding the larger built
environment.

APPENDIX F – BUILDING SECURITY AND SITE
Security will be based on Crime Prevention through Environmental Design (CPTED). These strategies
include:




Natural Surveillance – A design concept directed primarily at keeping intruders easily
observable. Promoted by features that maximize visibility of people, parking areas and
building entrances: doors and windows that look out on to streets and parking areas;
pedestrian-friendly sidewalks and streets; adequate nighttime lighting.
Territorial Reinforcement – Physical design can create or extend a sphere or extend a sphere
of influence. Users then develop a sense of territorial control while potential offenders,
perceiving this control, are discouraged. Promoted by features that define property lines and
distinguish private spaces from public spaces using landscape plantings, pavement designs,
gateway treatments, and “CPTED” fences.
Natural Access Control – A design concept directed primarily at decreasing crime opportunity
by denying access to crime targets and creating in offenders a perception of risk. Gained by
designing streets, sidewalks, building entrances and neighborhood gateways to clearly
indicate public routes and discouraging access to private areas with structural elements.
Target Hardening – Accomplished by features that prohibit entry or access: window locks,
dead bolts for doors, interior door hinges.
