The Bow Project

March 2013

Safer. Smarter. Tyco

Profile of a Unique Project

• The Bow Building is the tallest building in Western Canada at 58 stories. It has replaced the Calgary Tower as the prominent landmark on the Calgary Skyline.• It was recently named the world’s 4th most spectacular Corporate Head Office building by Emporis, a global provider of building data.

Design Features

The Bow has several design features that make it unique in North America . Some of these features include:• Its crescent shape which creates a floor plan that

maximizes views and access to natural light • The orientation of the building. The atrium extends the

full height of the SW face to harness the sun’s energy to augment heating requirements to the rest of the building

Design Features

The view to the SW

4

Design Features

• The Bow Building utilizes a “Diagrid” structural system. The diagonal and vertical frames not only provide superior structural efficiency, but also create a striking graphical presentation on Calgary’s skyline

5

Design Features

Sky Gardens

• There are 3 “sky gardens” which function as an indoor park environment - with trees, vegetation and seating

6

Design Features

• The floor plates within each section do not extend to the exterior of the building allowing views downward into the garden atriums within each ‘tranche’.

• The building is in fact built like 3 separate buildings placed one on top of the other – 3 “tranches”

7

Design Features• Many of the offices have windows that open to the atrium

and there are in fact 1506 operable glass vents that let in outside air also

Building Facts

The site:• Area covers the majority of 2 city blocks • Below grade parking structure is 6 levels (x 2) and

holds 1390 vehicles and 420 bicycles and extends under 6th Ave to the former site of the York Hotel where the 2nd tower will be constructed.

The building:• 58 stories high • 1.9 mil sq ft of rentable space – approx 32,000 sq ft per

floor• 2 retail floors and 4 mechanical floors

9

Construction Facts

• The largest steel project ever built in Canada (45,000 tonnes of steel)

• The concrete foundation was the 3rd largest continuous concrete pour in the world (took 3 days and 500 people)

• 82,500 sq meters of glass panels (the equivalent of 10 football fields)

• 1.6 million pounds of sheet metal used for the mechanical systems

• 1,000,000 conduit runs with 232 individual transformers for electrical requirements

10

Challenges

1. Size & Scope of Project:• Largest building in Western Canada• 5 year + Construction Project• Construction Logistics:

• Moving people and equipment into the building and up and down floors:• 300+ electricians• 22 trades • more than 100 sub-trades• >2000 trades people on site at any given time

11

Challenges

2. Unique building design:• Curved building with unique building finishes• Massive floor plate (32,000 sq ft per flr.)• Sky gardens (2+ story high atriums with plants)• Inside office windows that open to atrium• Outside windows that open to the outside• Raised sub-floor with removable tiles

12

Impact on Fire Systems: (Size & Scope)

Fire Alarm System Logistics:• 34 Fire alarm

“nodes” networked together on a fibre backbone

• 20,000 fire alarm devices

Fire Alarm Node

Central Riser L4 (2010)

Size & Scope

• 80 kilometers of sprinkler pipe• 560 sprinkler hose valves and 128 control valves• Just under 30,000 sprinkler heads

14

Size & Scope

Fire Alarm System Logistics:• The Annunciator

panels seen here each include over 2km of wire in a 3’ x 7’ x 1’ enclosure and over 2900 point addresses including both switches & LEDs

Overcoming Challenges

21

Overcoming the Challenges

• Pre-fabricated Fire Alarm Termination Cabinets with termination points for each node. SimplexGrinnell communication cards prewired on a back plate to facilitate a “plug & play” connection point on site.

22

Overcoming the Challenges

Plug & Play I/O Termination Panel

23

Overcoming the Challenges

• Sprinkler Fabrication Shop able to cut pipes to fit in elevators

• ‘Round-the-clock’ deliveries of sprinkler pipe to avoid traffic issues and to work around other trades for crane & skip time

ConclusionTestimonial from Western Electrical Management:

“We commend Simplex Grinnell (SG) in their performance as the fire alarm system supplier for the Bow project under some challenging conditions including an

.

The personnel assigned to the project within SG’s office and onsite were very co-operative and demonstrated a both during the construction, verification, and testing stages of the project contributing to this project’s success for the owner, construction manager, and ourselves as the electrical contractor.

Many thanks and we would be honored to work with Simplex Grinnell on future endeavors.”
