Project Description

Atria II & III - 2007 Parking Garage Repairs

In Mid July 2007 Albatech Building Restoration Inc. started 2007- Atria II & III Parking Garage Rehabilitation Program.

The Parking garage at 2225 and 2235 Sheppard Avenue East is a 2 level underground structure with one suspended level and one on grade parking level located directly below the two 17 storey high-rise commercial office buildings incorporating retail and office occupancies constructed in circa 1987 (Atria II) and 1990 (Atria III). The total area of this garage is approximately 488,600 square feet, of which 254,845 square feet is suspended slab. The parking garage extends out past the building above creating a podium deck/garage roof slab above. The structural system of this garage is cast-in-place reinforced concrete construction. The suspended slab is a 2-way slab, approximately 12” thick with drop panels  supported by a combination of columns, foundation walls and shear walls. Access to the garage is from the entrance/exit on the east end of the garage.
