ESSO PLACE – 55 ST. CLAIR TORONTO

Owner: Bramalea Limited
Architect: The Webb Zerafa Menkes Housden Partnership

This precast concrete and glass clad terraced office building is located on St. Clair Avenue, west of Yonge Street in Toronto. 

The reinforced concrete frame incorporates modified drop panels to frame the thirty by forty-five feet rectangular bays, and reinforced concrete transfer beams and spandrels to pick up the offset columns above, which create the set backs to frame the terraced levels.

The use of large modified drops, over the columns, of this unique structural system minimized the thickness of the slabs to only 91/2 inches normally used for spans up to 30 feet.

A three level subgrade parking structure is located below the office block. The same substructure also provides for a truck loading dock, and receiving area.
