The province’s concrete industry has once again recognized the innovative use of this principal construction element with the presentation of the 2017 Ontario Concrete Awards.
The Toronto Transit Commission’s (TTC) subway station at York University took home top honours in three categories: architectural merit, material development and innovation, and structural design innovation.
“On behalf of everyone at the TTC, I’m pleased that the hard work that has gone into designing and building the York University station has been recognized with these notable awards,” TTC chair Josh Colle said in a statement to the Daily Commercial News.
“The six new stations on the Line 1 extension were designed with both form and function in mind. We look forward to the opening on Dec. 17.”
The York University station, designed in accordance with the Toronto Green Standard, is located on the Keele campus. Two covered entry wings rise on the north and south sides of the common.
A lightwell provides daylight into the concourse and facilitates campus views. A roof structure links the two entrance pavilions and the lightwell, explains an awards description.
Glazing on the east side of the entrance structure provides natural light down to the concourse level. A major design element is the metal “cool” roof over the upper concourse and common entrances.
In terms of materials, specialty concrete mixes and construction techniques were used throughout the project. Elements include “V” columns and a “waffle beam” slab, the main roof slab/focal point. The V columns are HSS steel hollow-core columns structurally reinforced with rebar and studs which get encased in concrete, the release highlights.
The team included architect of record Adamson Associates, engineer of record Arup Canada, general contractor EllisDon Civil Ltd., forming contractor Avenue Building Corp. and material supplier St Marys CBM.

The LEED Gold building at the University of Toronto Scarborough is “strongly rooted” in sustainable design solutions. The 110,000-square-foot building has a cast-in-place concrete structure. To improve energy efficiency, six precast concrete earth tubes were designed in different configurations to help temper incoming fresh air. The majority of the labs feature the concrete structure as exposed ceilings and columns. The team included Diamond Schmitt Architects, Read Jones Christoffersen Ltd., EllisDon Corp., Avenue Building Corp., UCC Group Inc., St Marys CBM and DECAST Ltd.
The awards were scheduled to be presented at a banquet Nov. 29 held in conjunction with the World of Concrete Pavilion, part of The Buildings Show.
