This project called for the demolition of an existing structure and the rebuild of a new eight-level, 151-stall parkade for Public Works and Government Services Canada. Also included in the project scope was a new generator for the adjacent Alvin Hamilton Building.
Demolition was completed using a specialized hydraulic jaw crane to minimize disruption to the adjacent building tenants. (This same equipment was used in New York during the 9/11 cleanup efforts.) The demolition removed all parts of the existing parkade except for the piles and exterior foundation walls. The structure is also supported by bell and friction piles, concrete foundations, and a structural slab. The interior and exterior concrete is cast in place.
The new parkade includes an elevator, secure parking on the lowest level, and other basic features. PCL added value by devising a unique traffic rail design to increase aesthetic appeal, save the client money, and keep the project on schedule.
