Wright & Burnside Business Campus - Building 'B'

2012 TCA Tilt-Up Achievement Award - Office Division

Article tools: Coming soon!

Building 'B' is the first building of the Wright and Burnside Business Campus in Dartmouth, Nova Scotia, a 15-acre site which will include park space, walking paths, basketball court/exercise area, and a community garden. The architectural concept for the building, a three-story Tilt-Up construction with one level of underground parking, was to shift the third story of the building five feet from the front to the back which dictated the sequencing of the construction.

First, the foundation was constructed to provide a one-story parking garage. The footprint of the parking garage exceeded that of the building above which required reinforced concrete beams to support two- and three-story panels at the rear of the building. The main floor was then constructed with steel columns, girders and joists and concrete slab over a steel deck.

Eight-inch-thick two-story Tilt-Up panels with a height of 28 feet-9 inches were constructed on casting beds along with two three-story panels with a height of 40 feet-9 inches. These panels were erected on top of the foundation walls and braced to the main floor structure. Four panels with an overall height of 44 feet-9inches were also erected to form the elevator shaft that extended several feet beyond the roof. The steel structure forming the second and third floors was then erected and the concrete floors completed while the remaining panels were constructed.

Twelve-inch-thick three-story panels with an overall height of 41 feet-2 inches were then erected at a 5-foot offset from the two-story panels along the rear half of the building. These panels were temporarily braced to the third floor of the building until the roof diaphragm was completed.

Three small spandrel panels were also erected, one to complete the elevator shaft and one on each side to bridge the gap between the two-and three-story panels. The building is symmetrical and boasts 24-foot-wide windows. Additional features complementing the Tilt-Up panels include curtain wall glazing and composite panel canopies.

About the TCA

Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
