TORONTO – Centennial College is opening the doors to its trailblazing A-Building ─ Canada’s first LEED Gold, zero carbon, mass timber, higher-education building. A-Building, formerly known as A-Block, establishes a new gateway to Centennial’s flagship Progress Campus in Scarborough that supports Indigenous ways of being and teaching. An Indigenous Working Group made vital contributions to Indigenous elements of the build as the College worked with Colliers Project Leaders, EllisDon Construction, DIALOG and Smoke Architecture to deliver the approximately $112-million project. Spanning six storeys and more than 130,000 square feet, the expansion was accompanied by a 15,000-square-foot renovation. …Black Spruce from Chibougamau, Quebec, figures prominently in the mass timber structure of the A-Building, with generous wood exposures showcased through its cross- and glue-laminated columns, beams and floor slabs throughout. “…there were so many contributors and everyone really wanted to emphasize the first-of-its-kind mass timber structure,” said Dan Beadle from EllisDon Construction
