Highlights of our structural design include:

• Collaborating with the project team to evaluate alternate structural systems
• Selecting a cast-in-place concrete structure to provide thin floor profiles with future flexibility and accommodate a future topping slab for radiant heating
• Creating a REVIT model used for spatial and production coordination
• Preparing core-and-shell permit drawings and helping obtain city approval
• Designing transfer girders at Level 9 to support a two-story, set-back penthouse structure and at Level 2 to span drive lanes and parking below
• Detailing grade beams and caisson foundations to clear the property line, while permitting columns to be located adjacent to it
• Specifying materials and procedures for exposed concrete topping slabs to accommodate hydronic heating and achieve the desired polished finish
• Designing a suspended hybrid steel/concrete structure over a large opening

We also consulted on the building enclosure, including:

• Blind-side waterproofing, including developing details to integrate it with the positive-side waterproofing and vapor barrier
• Window wall system, including participating in a laboratory mockup, observing field testing, and helping resolve field conditions to mitigate leakage
• Aluminium composite material (ACM) panel cladding system, including developing details to integrate it with the window wall system
• Air/vapor/thermal barriers to maintain continuity and transition to wall openings
• Balcony and roofing systems, featuring vegetative trays, pavers, and ballast
