The Parking Structure Extension at the Ottawa Macdonald-Cartier International Airport consists of the construction of a four-story extension to the existing four-level airport parking structure. The 287,148-square-foot parkade contains 944 stalls and includes a new prime entry location and roadwork, linkage to the existing circulation system, the dismantling and re-utilization of precast and curtain-wall system (from the existing parking structure), and associated mechanical and electrical work. The new structure is cast-in-place concrete with posttensioned beams and slabs overlaid with a waterproof membrane and asphalt topping.
The project was originally forecast to be completed in December of the same year it was begun but risked running into the following spring, as the colder months of November and December would not allow for waterproofing and asphalt to be done. The decision to remove the reshores from the lower level of the garage three weeks ahead of schedule allowed underground plumbing, grading, and mechanical and electrical services to proceed ahead of schedule. PCL successfully turned over half of the structure six weeks early, allowing the Airport Authority the opportunity to generate additional revenue from the parkade.
