The State Place Condominium Project, Chicago, IL
Innovative Box Culvert Solution
for Balconies
A major residential development
is currently going on in the Southern section of downtown Chicago. The project consists of 4
residential structures, of which
there is a 24-story tower and 34story condominium buildings. A
total of 243 condominiums will
be finished by the fall of 2004.
In order to achieve this aggressive construction schedule, PERI
developed a Box Culvert System
that would allow both walls and
balcony to be poured simultaneously producing an architectural concrete surface. Each unit
could be moved by a single crane pick, thereby ensuring efficient cycling time.

The Shoreham, Chicago, IL
The Shoreham is one of the first
two high rises being constructed
on the Lake Shore East Development area in downtown Chicago,
IL. This 49-story condominium
tower is designed with floor to

of exposed concrete with two
sets of recessed balconies. PERI
was awarded the contract to
supply the forming solution for
the walls, decks, core structure
and facade.

Walls and Slabs Poured Monolithically Using
ACS-G – The Automatic Climbing System with Gallow
The various systems supplied by
PERI included SKYDECK for the
underground parking levels,
MULTIFLEX for the upper levels,
TRIO and custom DOMINO for
the interior walls and VARIO
including ACS-G for both core
structures and the KG 240 climbing bracket for the external shear walls. The ACS-G (gallow)
system was designed with the
internal panel having an offset,
thereby allowing the wall and floor to be poured monolithically.
This design feature enabled the
client to pour various floor
heights by simply adding extension splices to the top of the
VARIO panel.

The exterior ACS-R platforms
supplied by PERI were capable
of lifting more than 30 tons, enabling McHugh Construction to
use intricate steel forms with
ease. By using the lightweight
DOMINO Wall Formwork system
on the inside of the perimeter
walls, PERI provided McHugh
with a fast, flexible and safe forming solution. The wall formwork system was designed to
allow James McHugh Construction to sequence either the wall
or slab construction independent
of one another. This ensured a
flexible product that would permit them to adjust the pour
sequence accordingly.

12’11“(3.96 m)
Broadway 655 is the first office
tower built in downtown San
Diego in 12 years. It consists
of two underground and three
above grade levels of parking,
5,500 ft2 (510 m2) of retail space
and 20 levels of class A office
space.
In order to complete this project
on time, Webcor Builders ordered 6,120 ft2 (568 m2) of VARIO
wall formwork and ACS climbing
units to raise the formwork without the use of the crane. The
ACS configuration selected was
ACS-R (regular) units for the
exterior formwork and ACS-P
(platform) units for the interior
formwork. The advantage of this
configuration is that there are no
over wall obstructions thus permitting the installation of pre-tied
rebar which is critical for the construction of a heavily reinforced
core in a seismic zone. The rebar
is safely and efficiently set from the
upper access platforms (level +1)
of the interior ACS-P units.
In order to keep the construction
sequence flexible, the interior
and exterior ACS units are climbed independently. Furthermore,
the two interior ACS-P units and
the six exterior ACS-R units can
be climbed separately thus allowing an efficient flow of work
during the construction cycle.
Ben Smetak,
Structures
Superintendent:
“The ACS system was
incredibly versatile and
easy to use. The climbing
operation was fast, accurate and efficient. I am very
happy we chose PERI for
this job.“

Residential and Community Facility St. Marks Avenue, Brooklyn, NY
Easy to Use Slab Forming System and Engineering Service
for Higher Efficiency on-site
The St. Marks Avenue Associates
residential and community facility
includes a 2 storey building with
2 floors of underground parking.
The parking garage slabs and
partly the second floor and third
floor slabs of this project had to
be constructed as 1’11“(0.6 m)
thick waffle slabs with a 3 ft x 3 ft
(0.9 x 0.9 m) grid spacing. The
contractor needed a slab formwork system, which could handle
both, the waffle slab at the parking garage levels and the flat
slab at the typical floors, without
switching systems in the middle
of the project. SKYDECK Ply was
used because it was able to
handle all the tasks required.
The 7’ 4“ x 7’ 11“(2.25 x 1.5 m)
grid achieves efficient support
spacing but could randomly be
changed if dictated by any
obstacles. Even sloped areas
such as the parking garage
ramps used the SKYDECK Ply
system.
The position of the props is
already determined by the
prop grid of SKYDECK. This
helps increase erection speed.
Any normal plywood can
be placed on the SKYDECK
Ply system, no matter
whether a certain structure
is to be formed on the soffit. When using narrow filler strips over dropheads
the plywood can be reused
directly after early striking.
Francisco Vásquez,
Superintendent:
“The simplicity of PERI´s SKYDECK Ply
system and great site and engineering
service helped us to work fast and safely
from day one.“

Hyatt Hotel Convention Center, Denver, CO
PERI Provides Versatility, Efficiency, and Safety
Needed to Maintain 4-Day Floor Cycle
For this project, PERI supplied
RUNDFLEX, TRIO, KG with
rollback and QUATTRO VARIO
column forms.
34 ft (10.4 m) architectural
columns formed using the
QUATTRO VARIO Column
System.
The new Hyatt covers approximately one city block in downtown
Denver. This concrete building
will provide 1,100 rooms with
three levels of parking space,
bringing the building to a height
of over 489 ft (149 m). The core
of this structure was built using a
combination of TRIO and RUNDFLEX. The major advantage of
this system was the ability to
form a circular wall with a straight
wall using only one standard
connection device (BFD).
Along with the QUATTRO VARIO
column formwork system, J.A.
Walker Company was able to
form various column dimensions
using only one system.
Derrick Walker,
Senior Superintendent:
“When performance counts, PERI is the
right choice. They gave us the versatility,
efficiency and safety we needed to maintain our 4-day per floor cycle.”

7 World Trade Center New York, NY
Unique Solution – Climbing Inside
a Steel Structure with PERI ACS
The 7 World Trade Center Tower
is the first building to be built at
“Ground Zero“ in New York City.
In order to meet the requirements
of having the highest possible
level of fire resistance and safety
against a terrorist attack, the first
80 ft (25 m) of the 7 WTC is designed with massive reinforced
concrete. This structure has a
95 x 69 ft (29 x 21 m) reinforced
concrete core which forms the
“load-bearing backbone” of the
entire building.
A special consideration on this
project is that the steel construction precedes the concrete core.
Thus, during the design of the
wall formwork operations this
gave rise to some special considerations: i.e. limited space of
only 20‘’(50 cm) when stripping
the PERI VARIO external wall
formwork. The formwork has to
be raised as the reinforcement
placed from an outside access
area. This is carried out by using
electric chain hoists which are
attached to specially-designed
gallows. The PERI specialists
positioned these on the elevated
working platforms on level +1.
Due to the fact that the steel
structure runs through the entire
core, the formwork for the area
where the reinforced concrete
and steel structure meet, had
to be designed with low dead
weight. Only in this way is it
possible for the construction
crews to efficiently carry out
manual forming. Altogether,
14,634 ft2 (1,360 m2) of PERI
VARIO formwork is being used
for the construction of the core
walls. PERI’s formwork utilisation
made a fast and efficient contribution to ensure a cost-effective
construction progress.

Waste Water Treatment Plant, Colorado Springs, CO
Versatile Radius and Wall Forms Save Costs on
Waste Water Treatment Facility
Western Summit, a specialty
builder of Waste Water Treatment facilities has used PERI as
its formwork system supplier for
several years. On this jobsite in
Colorado Springs, CO, over
20,000 ft2 (2,000 m2) of TRIO
were used. This system was
chosen because it can be easily
configured to fit the 20 different
structures that were to be formed. The ease of erection was
another contributing factor in the
decision to use TRIO because
the pool of skilled labor is an
increasing problem. Both the
radius wall system (RUNDFLEX)
and straight wall system (TRIO)
utilizes the same connection
device (BFD), therefore eliminating confusion and erection time
on a jobsite.
Scott Hill (left) and Larry McKinney,
both Civil Superintendents:
“We have found the RUNDFLEX radius
forms and TRIO wall forms so versatile
and efficient that we have purchased both
systems,“ stated Larry McKinney.
RUNDFLEX is sent to the
site flat and then adjusted
in the field to the required
radius. This saves transportation costs, because the
full volume of the shipment
can be utilized. It also allows the radius of the formwork to be changed on site
to fit the various structures
required.

Cited as one of Cincinnati´s
“Nationally Significant Buildings“
the National Underground Railroad Freedom Center was created
to comemorate the enslaved
fugitives who sought freedom
during the 1800´s. The Underground Railroad was a symbolic
term given to the routes enslaved African Americans took to
gain their freedom from prosecution. Former slaves and other
“free“ individuals acted as conductors by aiding fugitives to
their freedom. This 19th century
freedom movement challenged
the way Americans viewed slavery and freedom.
In order to recognise this chapter
in history an $ 110 Million Learning Center has been built in
downtown Cincinnati, Ohio.

Versatile Products and Precision of PERI Prove
Successful on new Quebec Hydro Project
PERI’s “Ready-for-use“ Service
Assembly Team: PERI Germany and PERI Toronto
PERI GRV system, utilized for the tunnel roof.
The formwork employed
had to be versatile
enough to meet the
strict tolerances specified by Hydro Quebec
(1/8”, 3 mm) while being
able to withstand enormous concrete loads
from slabs up to
10’(3.05 m) deep.
PERI pre-built these
complex elements in the
controlled environment
of the pre-assembly
facility. This enabled not
only time and labour
savings in assembly and
erection requirements at
site but also assurance
of a high precision
finished product.
Hydro Quebec, one of Canada’s
leading power supply companies,
continues with its aggressive
program to meet the increasing
demand to provide more clean
power to its many customers
throughout North America.
PERI has been chosen by AECON Civil (Montreal) as the formwork and access scaffold provider for the Toulnustouc Hydro
Electric Power Project.
After struggling through a long
and difficult power “black out” in
2003, Hydro Quebec increased
its commitment to supply a huge
grid including major cities in both
Canada and the US.
Due to the confined space inside
the tunnel at the roof area, crane
access was not available to
maneuver the forms. As part of
the complete project services,
PERI’s engineering department
developed a scheme for man
handling the large elements into
position without the use of any
cranes.
The PERI team of
assembly experts prearranged the entire roof
form in the assembly hall
to assure proper fit for all
the elements.
The form for the front
section of the tunnel
was also pre-assembled
at PERI’s shop.
The form was engineered to be able to be
transported to site in
complete elements for
faster erection on the
space restricted site.
The TRIO Wall Forming
System was used to
quickly, safely and efficiently form the lower portion of the tunnel walls.
Increasingly, contractors are demanding pre-assembled and transportable formwork elements such as slab tables, special column
formwork, RUNDFLEX elements or customized formwork.
At numerous logistics centers, PERI provides this service in
state-of-the-art assembly halls. Here, well-trained and highly qualified personnel work with optimally-designed machines and equipment which ensures cost-effective solutions even for the most unusual architectural requests.

SKYDECK was used for shoring the massive podium of
this phase of the project. The
large prop spacing means
more room for moving formwork equipment or storing of
construction materials.
Michael Chartrand,
Superintendent:
“Using SKYDECK & TRIO on this project
was ideal, as it allowed faster cycling of
the formwork from one building to the
other, which reduced material and cost.”
Montreal Subway Tunnel (Phase S-04), Montreal, Quebec
PERI’s Wide Range of Versatile Equipment Delivers The
Best Formwork Solution at Montreal’s new Subway Line Project
For the expansion of Montreal’s
subway grid, PERI´s engineers
designed a system which allowed the contractor to maneuver
the formwork through the confined underground space of the
tunnel using mostly standard
components.
Utilizing GRV walers, GT 24
and MULTIPROPs, this simple
Tunnel System met the required specifications for versatility
and high quality of concrete
finish.
A hinged section of the system
allowed the tunnel form to be
moved in two separate pieces.

“Using PERI’s formwork on such a confined
site, demonstrated the flexibility of the
system to maneuver inside the right angled
tunnels both very easily and quickly.”

The painting of the elevated water tower in
Barrie was a challenge for the contractor due
to the fact that a large automobile dealership
was directly below. Thus, Dupont Painting
required a versatile scaffolding system to
create an enclosure ensuring that no sand
from the sandblasting operation would fall
down and damage the new vehicles below.
Dupont Painting used the PERI UP scaffolding system which rode to a height of approximately 150 ft (45 m). This worked well with
the PERI UP scaffolding in that it created a
complete enclosure. A beam and plywood
platform just below the tank was installed to
contain all debris from sandblasting in the
enclosure.
The highly ridged construction and the basic push pull
ties designed from simple
stock items made the overall structure an efficient
and safe work environment
even with the 62 mph
(100 km/h) winds that was
experienced during the
project.
Overall access was incorporated through one of the
PERI UP scaffold bays with
the PERI UP STAIR
System.

“The 150 ft high PERI UP
scaffolding system worked
very well. The plywood
platform just below the
tank and the complete
enclosure contained all
debris from sandblasting.
We then attached hoses to
the floor of PERI’s deck
and all debris was swept
into the hoses and down
to the ground into large
garbage bins.”

Safer Working Conditions – Reduced Costs
PERI FB 180 Working and Safety Platform
A versatile working and safety
platform has to fulfill different
requirements: a safety handrail
system, working, forming and
reinforcing scaffold. The new
PERI FB 180 Platform can achieve all this with just one folding
platform, one intermediate platform and well engineered accessories.
Large uniform bracket spacing 8‘2‘‘(2.50 m) and few
parts result in considerable
savings in labor and material costs. The finishing platforms are simply attached
to the wall using a simple
bracket.
With a width of 5‘10‘‘(1.80 m)
the FB 180 is the right working
platform for forming and placing
reinforcement. It is designed for
formwork up to 17‘8‘‘(5.40 m) in
height and offers sufficient space
for a working scaffold.
