safely and cost-effectively
To Our Valued USA Customers,
Dear Canadian Readers,
2005 was an exceptional year for
PERI worldwide and in particular
for PERI in the United States.
Our revenue in the U.S. for 2005
was up by over 30% from 2004.
This dramatic increase in our
business is most evident in our
logistics operations which handled 110,000 tons in 2005 which
is a 38% increase over the previous year. To fulfill the increasing demand for PERI’s formwork and shoring systems we
have invested a considerable
sum in additional equipment for
our rental fleet.
Across Canada, more and more
construction undertakings are
becoming progressively complex
while schedules and safety requirements are more demanding
than ever. As our industry continues to evolve, the demand for
more innovative, cost effective
systems and reliance on safe,
dependable service providers
becomes ever increasingly
essential.
In 2005 we have also begun construction of a new distribution
yard in Orlando. This ten acre
facility will service the southeastern U.S. and the Caribbean.
In addition, PERI opened its new
corporate headquarters building
in December which is situated
adjacent to the Baltimore distribution yard.
In this issue of PERI scope we
profile eight jobsites in the U.S.
that illustrate the range of projects on which PERI is involved.
We are excited to introduce the
Climbing Panel Protection (CPP)
system which is being used for
the first time in the U.S. on The
Regatta project in Chicago. This
system provides for an unparalleled level of safety for the construction of highrise towers.
We recognize that our success
over the past year and our continued growth are only possible
with your trust in our products
and service. We truly value your
business and look forward to serving you in 2006.
PERI’s success in Canada is a
result of our ability to effectively
provide constant product improvement and innovations, such as
our new Climbing Protection
Panel (CPP), along with our many
services which include complete
engineering services, site support and safety training as well
as formwork preassembly, logistics support and scaffold erection and dismantle services.
We’re proud of our achievements and our PERI scope publication provides us with an opportunity to demonstrate the many
innovations and reliable services
we provide to the numerous construction professionals in our
industry, across North America.
In this issue of the PERI scope,
we highlight a selection of diverse projects from across the

Paul Treacy, Concrete Superintendent:
“Implementing the PERI Climbing
Protection Panel and the SKYDECK slab
system has allowed us to work safely and
extremely efficiently even in high winds.”
The Lakeshore East development area in Chicago is a 26 acre
parcel of land located on the
South bank of the Chicago River
at Lake Michigan. This area will
be a host to over 25 new structures in the next few years. The
Regatta building marks James
McHugh Construction`s third project at Lakeshore East, along
with the Lancaster (see PERI
Scope 2005).
This 466 ft (142 m) building will
sore 44 stories in the air and provide over 700,000 ft2 (65,000 m2)
of living space with over 325
condominium units.
One of the interesting features
of this structure is the curved
curtain wall facing Lake
Michigan. This unique structure
provided itself with the ideal
opportunity for PERI to supply
the new Climbing Protection
Panel (CPP).
The CPP system encloses the
work enviroment, providing a
comfortable and safe working
area. The system ensures delays
due to weather are minimized
and production levels are increased by eliminating the need to
work on a ledge of a 44 story
building. The CPP is lifted by a
crane and simply connected to
the slab via a bracket. The system uses a plywood backing
connected to steel supports,
making it easy to attached any
necessary signage. An ideal platform for advertising and providing a weather tight system at
the same time.
PERI also provided the VARIO
wall formwork system, the SKYDECK modular slab formwork
system, the Automatic Climbing
System (ACS) and QUATTRO
columns for this project.

The Climbing Protection Panel CPP
Working Safer and Quicker 44 Floors High
The Climbing Protection Panel, better
known as the CPP, allows laborers to work
100% efficiently, without the discomfort
of high winds, extreme weather and associated falling hazards. The enclosed
system was designed to ensure a high
level of safety against falling objects and
reduce delays associated with high winds
and poor weather conditions.
Incorporating PERI’s know-how on this
project enabled James McHugh to keep
schedule a priority. The main placing boom
located in the middle of the floor was designed to be carried by the Automatic
Climbing System, eliminating the extra
crane time needed to move the system
separately.

The VARIO wall form incorporated with
the ACS-G (Automatic Climbing System
Gallow) system was designed to allow the
slab and wall to be poured simultaneously.
The wall panels were hung on a gallow
system allowing units to be moved independent of the slab.

University Club Tower, Milwaukee, Wisconsin
Automatic Climbing System ACS
Helps Free Up Crane
Findorff was awarded the construction of the 36-story
University Club Tower in
Milwaukee with the intent of
building this structure only 25
feet away from two adjacent
buildings. With space being a
premium on the site and only
having room for one tower
crane, it was decided that only
PERI Formwork Systems could
supply the necessary solutions
needed for this job.
Incorporating the SKYDECK slab formwork
system as well as ACS reduced the required crane time.
ACS is designed to climb with hydraulics
set on a rail which is attached to the
concrete wall.
PERI‘s ACS (Automatic Climbing
System) was chosen for this project because Findorff wanted to
run the shear walls ahead of the
horizontal slabs. Using standard
ACS-R brackets, PERI supplied a
solution which reduced overall
man power and eliminated the
need for a crane. PERI also incorporated a placing boom from the
center core on the ACS system,
offering another significant
reduction in required crane operation. The design of this overall
system allowed Findorff to form,
strip and climb without the use
of the crane in a four day cycle.
PERI supplied Findorff with a
supervisor that stayed on the
University Club Tower job for six
weeks, helping the crew to set
up the system, teach them the
advantages of the system and
ensure operations were carried
out in a safe and efficient
manner.
The modular SKYDECK slab formwork
system eliminates the need for a crane.
High production rates can be achieved
using this aluminum system.
Clifford Gorn, Superintendent:
“Findorff‘s decision to use the PERI
Formwork System has been a wise one.
From the first time I was introduced to it,
until now, we have received incredible
field service and a product on the cutting
edge in the industry.“

The cantilevered SLT 375 mainbeam used
on the SKYDECK system, allowed the
client to effectively and safely work on the
slab edges.
Contractor:
Hoffman Construction, Portland, OR
Field Service:
PERI Woodland, WA
The Willamette Riverfront area in
Portland, Oregon will become a
host to over 15 structures similar
to the “Block 30” Condominium
project. These twin towers will
house mainly condominiums,
with office and retail space
located on the bottom floor.
The 60,000 ft2 (5,600 m2) floor
plate of this project includes two
buildings with approximately
11,000 ft2 (1,000 m2) footprint per
floor.
In order to achieve a six day pour
cycle, Hoffman Construction
elected to use the patented
PERI SKYDECK slab formwork
system for the floors and the
TRIO Shaft system for the cores.
The PERI SKYDECK system uses
a drophead technology which
allows the shores to stay in place
during the stripping procedure.
This saves in labor costs during
the erection and dismantle stages and reduces equipment
requirements as only the level
being formed is required.
Using a modular decking system
on this project also allowed
Hoffman Construction to eliminate the need for custom solutions
for the cantilevered balcony
design on this structure. Using
standard components, PERI was
able to provide the client with an
effective design using a cantilevered SLT 375 mainbeam on the
SKYDECK system, providing a
safe and efficient work environment for any finish work required
on the slab edge.
SKYDECK main beams and panels have
been stripped. The temporary props remain
until the correct load-bearing capacity of
the slab concrete has been reached.

Kiewit Western Co. was awarded this contract with an expectation to deliver an architectural
finish on all exposed structures.
In order to accomplish this task,
PERI was brought on board to
supply a forming system that
would allow Kiewit to stay on
schedule while delivering a
superior product. For this project
PERI supplied the VARIO wall
formwork system for those sections requiring exceptional finish
as well as the TRIO wall formwork system which allowed
Kiewit to meet their deadlines.
For the air traffic control tower,
PERI supplied the proven KG
Climbing Bracket along with the
VARIO wall formwork system.

chosen for this project because of the
capability to attach a trailing platform, thereby allowing the client to perform any
finishing work after the pour has been
completed.

The VARIO wall formwork
system is comprised of
wooden girders, steel
walers and plywood, so
box-outs and reveals can
be simply screwed onto
the plywood.
An architectural colored
finish with reveals is the
finished product when
using the VARIO wall formwork system.
The KG climbing bracket was used to carry the 17 ft
(5.20 m) VARIO panels. Using the KG system allowed the
client to move the entire system without removing the
wall panel from the climbing system during the jump
phase. This increased production and reduced crane time.
Another advantage of the KG system is the ability to roll
the panel away from the wall while attached to the bracket. The KG system has a roll back distance of 30 inches
(75 cm) allowing easy access to the formwork panel for
cleaning.

McAllister Academic Village, Phoenix, Arizona
SKYDECK and TRIO - Modular Systems
Offer Labor Savings
Arizona State University will offer
freshmen for the fall semester in
2006 the opportunity to live in
the new McAllister Academic
Village. This new facility will
house upwards of 2,000 students, providing them with
586,000 ft2 (55,000 m2) of
academic and residential space.
Concrete Structures Inc. have
been tasked to deliver the 5 concrete structures on this site. In
order to meet and exceed the
scheduled deadlines, it was their
decision to use PERI to supply all
slab and wall forming systems
for this project.
Utilising the modular SKYDECK slab formwork system helps keep the project on
schedule. PERI also offers engineering
service as well as site support to ensure
maximum performance of the system. A
short learning curve, coupled with detailed
information on erection techniques helps
keep the system performing above expectations. SKYDECK is constructed out of
aluminum to reduce worker fatigue and
increase overall production time.
Adam Arenivas, General Foreman (left)
and Damien Rustebakke, Project
Manager: “A large selection of available
equipment from PERI offers a competitive
edge in this hot market.”
PERI supplied the modular
SKYDECK slab formwork system
and the modular TRIO wall
system in order to ensure labor
savings through simply designed
systems. The learning curve for
using these two systems proved
to be minimal. Using a modular
system allows for flexibility on
jobsites along with repetition.

Scottsdale Waterfront Residences, Scottsdale, AZ
Modular SKYDECK Slab Formwork System
Used on Difficult Floor Layout
The Scottsdale Waterfront
Residence project located in
Scottsdale, Arizona presented a
situation in that Opus West construction needed a slab system
that could adapt to the difficult
floor layout designed on this
structure. Every floor of this building had a changing floor layout.
For this project, PERI Formwork
Systems supplied over 65,000 ft2
(6,000 m2) of SKYDECK slab
formwork system. The advantage
of the system is seen when
using it on a difficult floor layout.
The modular panels can be rearranged into the necessary configuration easily and quickly. The
perimeter area of the slab was
formed using the UNIPORTAL
system. This allowed the contractor to fly smaller units and therefore keep on schedule.
Another system supplied to this
project was the TRIO column
formwork system. Columns
varied from 18“ x 18“ (45 cm x
45 cm) to 30“ x 48“ (75 cm x
120 cm).
This difference in column
size was easily overcome by
using only one system (TRIO
Column) for this project.
Norm Crawford, General
Concrete Superintendent:
„Using the light weight
SKYDECK system we were
able to increase our productivity and stay ahead of our
aggressive schedule. We
especially like the great versatility and experienced a
very short learning curve in
using this system. The technical support and site supervision we have received
from PERI‘s team has been
above and beyond anything
experienced before from a

University of Texas, San Antonio Parking Structure
Pre-Assembled Beam Formwork
Helps Achieve High Level of Production
The University of Texas at San
Antonio has several construction
projects in progress at the
moment of which a two level,
630 car, student parking
structure is currently being built
by U.S. Structural Concrete Inc.
of San Antonio. This structure
consists of approximately
100,000 ft2 (9,290 m2) of slab
work and approximately
33,000 ft2 (3,065 m2) of beam
work per level.
The difficulty of this project was
seen in the tight scheduling for
completion.
With formwork equipment only
expected on site for mid May,
the concrete work needed to be
completed by end of July,
leaving only two and a half
months to finish the concrete
work.
The special beam system designed by PERI offered a
solution with no tie (dry tie at bottom) and minimal
shoring requirements.
Using MULTIPROPs along with the GT 24 girder, large
loads are carried from the 36 inch (91 cm) deep beams.
In order to solve this problem,
PERI delivered a pre-assembled
beam formwork system allowing
the client to achieve immediate
levels of high production with an
architectural finish. Using
rentable components, PERI was
able to design an integrated
beam system along with the

Chocolate Condominiums, Calgary, Alberta
PERI UNIPORTAL Table System
Helps Achieve Four-Day Cycle
One of the main difficulties seen
in the Chocolate Condominium
project was the ability to keep a
four day pour cycle with a safe
and efficient slab formwork
system. To achieve this, Elite
Formwork Inc. decided to use
the PERI UNIPORTAL table
system. By using this system,
tables ranging in size from 16 ft
x 26 ft (4.80 m x 8.00 m) were
effectively flown by using the
self leveling C-Hook. The advantage of this system was seen
when forming the 16 ft (4.90 m)

KG Climbing Bracket Offers Safety and Ideal Working
Conditions for Architectural Concrete Work
One of the challenges faced in
constructing the 20 storey
Westgate Condominium Tower
was the exposed architectural
exterior walls. In order to produce the level of finish required
for this building, Elite Formwork
Inc. used the KG Climbing
Bracket along with an extension
for the finishing platform. Using
this system allowed the contractor to perform the required finish
work after the pour had been
completed and the form jumped
to the next lift.
Another critical aspect of the job
was the ability to pour all vertical
work within a 12 hour window.
To achieve this, the client also
used the TRIO wall formwork
system.
Combining the SKYDECK slab
formwork system and the UNIPORTAL table system, Elite was
able to achieve the level of production required for the 8,700 ft2
(800 m2) footprint.
Another system used on this
building, was the TRIO Shaft

request, PERI supplied the TRIO
modular wall formwork system.
By simply screwing the 4 inch
(100 mm) liner to the back of the
panel an architectural „stonelike“ finish was achieved.

MULTIPROP tables measuring 8 ft x 23 ft (2.40 m x 7.00 m)
are sent to the site pre-assembled at the PERI facility.
The next phase of this project
consisted of a 5 ft (1.50 m) thick
solid concrete deck. PERI supplied pre-assembled tables using
wooden GT 24 girders and SRZ
steel walers placed on top of
MULTIPROP towers. The advantage of the system was seen in
using the MULTIPROP towers.
They were assembled on the
ground and then simply raised
into place. The pre-assembled
tables were then placed on top
of the erected towers. Aecon
Civil was able to achieve a high
level of production using this
method of construction.

Royal Ottawa Hospital, Ottawa, Ontario
MULTIPROP System Saves Over One Week
in Construction Process
In November 2004, the construction phase began for the $148 million dollar construction program for
the Royal Ottawa Hospital. The
additional facility will be designed
to accommodate over 200 patients
from surrounding areas. Bellai
Brothers Construction Ltd. was
awarded the contract to supply the
concrete work for this 399,000 ft2
(37,000 m2) facility. In order to keep
this project within the scheduled
timeline, Bellai needed a quick
system which would allow them to
shore high bays and areas with
column capitals. The PERI modular
SKYDECK slab formwork system
was chosen for this project as the
proven aluminum MULTIPROP was
the ideal solution to form these
high floors. Using the MULTIPROP
in conjunction with the MULTIPROP connector, Bellai was able to
assemble the high bay towers on
the ground and use a crane to lift
the entire section in place. This significantly improved the schedule
and created a safe environment as
workers were not required to climb
the system to install separate pieces. This MULTIPROP tower was
used to shore a cantilevered roof
support. This tower reached a
height of over 63 ft (18.90 m).
The maximum number of
MULTIPROPs on site consisted
of over 8.500 MP 480’s. This
was another vital component in
choosing PERI for this job. The
availability of equipment was crucial in meeting deadlines.
In shoring such heights, PERI’s
engineering team were able to
calculate the loading conditions
imposed on this system, ensuring a safe and efficient product
and working environment for
those around the structure.
SKYDECK panels were used on the top of
these high MULTIPROP towers. Panels
were safely placed from above.
64’ (19.51 m)
Using standard MRK frames ensures the tower is
able to carry the necessary
loads imposed on the
system.
The MULTIPROP is designed to be stacked on top of one another efficiently and
effectively using the MPV-2 Connector.
Shown above, two MULTIPROP 480‘s and
two MULTIPROP 625‘s have been connected to reach a height of 63 ft (18.90 m).

“We were able to build this massive structure on the ground and safely
tilt it into place with the crane. It only took four hours to build four bays,
which would have taken us one week with a conventional system.“
The PERI MULTIPROP
can be used as table or
tower system.
The MULTIPROP frames
can be fixed on the outer
or inner tubes. A built in
measuring tape ensures
the correct height.
Height extensions can be
done fast and without any
tool using the connector

Molson Indy, Toronto, Ontario
PERI UP Scaffolding
Keeps Molson Indy Race on Schedule
The Molson Indy has celebrated
20 amazing years of world-class
racing in the city of Toronto. Since
1986, over three million fans have
experienced the three-day event
making it one of the most anticipated spectator events year after
year.
Jim Tario,
Race Operations:
“In 20 years, I have seen a
lot of different systems,
however, I can say that
PERI always gets the job
done on time, on budget
and with safety in mind.“

Sheraton Hotel, Toronto, Ontario
PERI’s GT 24 and PERI UP Scaffolding
Keeps Lobby Open During Construction
The lobby renovations at the
Sheraton Hotel in downtown
Toronto, Canada was a challenge
for the PERI scaffold team. The
contractor decided to go with
PERI because of the look and
minimal obstructions due to design. The contractor also had a
challenge because while the
lobby and front entrance renovations were planned they had to
phase the work to allow minimal
inconvenience to the hotel
guests and employees.
Using the PERI UP scaffold
system and the GT 24 girder to
allow large spans and create an
aesthetically pleasing platform to
allow the contractor to work
above while business went on as
usual for the hotel.
PERI provided all labor to install
and dismantle all of the PERI UP
scaffold in the lobby and in the
front entrance. PERI completed
the project ahead of schedule
due to the engineered PERI UP
modular scaffold system.
The lobby functions were not disturbed
through an engineered scaffold solution
which minimized any obstructions.
Scott Gregory, Superintendent:
“The GT 24 worked well as they allowed
my crew to span large distances between
shores. The system also allowed me to
run two jobs (one above and one below) at
the same time which cut my time in half.”

Safe and Productive Working Conditions
despite Large Building Heights
PERI CPP Climbing Protection Panel
The safety of site personnel is the highest
priority for all those in charge of site operations. Furthermore, experience shows that if
site personnel are able to work under safe
conditions productivity increases. This fact
has led PERI’s engineers to develop a wide
range of safety features such as the new
PERI CPP Climbing Protection Panel system.
The top three floors are always completely
enclosed by climbable protection panels. The
solid plywood facings prevent falling and give
reliable protection against wind and weather.
The climbing protection panel is permanently
and safely connected (even during climbing
operations) at the front of the slabs by
means of climbing rails and shoes.
Climbing takes place in cost-effective units
which are, of course, matched to the crane
capacity. Thus secure and, at the same time,
comfortable working conditions are created,
and no objects, such as tools or debris can
fall off. All work on the external facade can
then follow quickly which accelerates the
construction progress. Site crews are also
protected against falling and the vagaries of
the weather. This leads, in the end, to a tremendous increase in productivity.

“We are very impressed with the safety and wind protection of PERI‘s CPP platform system. I‘ve been working
with PERI for the last 5 years, and find PERI‘s formwork
systems to be very adaptable. With PERI ACS Formwork
and CPP platform, you get speedy results at the end of
the day.“
