The Bow Parkade Modifications
Constructed in the early 1950s, the Bow Parkade is an existing six-level parking facility located in downtown Calgary, taking up half of the block between 2nd and 3rd Street.
Constructed in the early 1950s, the Bow Parkade is an existing six-level parking facility located in downtown Calgary, taking up half of the block between 2nd and 3rd Street.
To accommodate the footprint of Phase 1 of the Brookfield Place Calgary project, three bays of the existing parkade had to be demolished.
Because the parkade is an important revenue generator, work had to be performed with no parkade closures other than reapplying the waterproofing membrane.
The scope of work included a new parking ramp, stairwell, elevator shaft, reinforcement of the existing framing elements, and enhancement of the seismic resisting system.

KEY CONSIDERATIONS
Challenge One
Since the parkade was an important source of revenue, the owner mandated that it had to remain open during the partial demolition and reinforcing of the existing structure.
Solution One
Entuitive worked closely with the owner, architects, and contractors to ensure the existing structure remained stable and safe during partial demolition. Temporarily changing the traffic flow pattern was necessary to achieve this.
Reinforcing the existing structure required minimal head room intrusions, involving external steel plate reinforcing of the existing concrete slab and beams.
