Location change for OGMA spring seminar

April 19, 2012  By Ontario Glass and Metal Association

April 19, 2012 – The Ontario Glass and Metal Association has announced a change of location for its upcoming spring seminar, First Canadian Place Tower Re-cladding – Redefining an Icon. The seminar will now be held at Tremco Canada at 50 Beth Nealson Drive in Toronto.

The First Canadian Place tower, constructed in 1975, is the
tallest office tower in Canada. Halsall Associates led the
pre-construction design team charged with re-cladding the distinctive
marble facade to address durability and safety concerns with the
deteriorated marble. Over the past two years, the marble has been
replaced with laminated glazing, renewing the image of the tower in what
has been the largest re-cladding project in Canada. The project is the
largest use of triple laminated glass cladding in North America.
Halsall will present evaluation of the existing building envelope and
design of the new cladding, with a focus on design challenges and the
balance between performance, durability, constructability and future
maintenance requirements.

The design and construction team making this project a success are Moed
de Armas and Shannon Architects (design architects), Bregman and Hamann
Architects (architect of record), Halsall Associates (pre-construction design engineers and project managers), Sota Glazing (glazing contractor for the tower), Ferguson Neudorf Glass (glazing contractor for the podium), Viracon (glazing fabricator), Clifford Restoration (demolition and building envelope restoration contractor for the tower) and
EllisDon (general contractor).

Please note: The construction aspect of the project will likely be presented in a future OGMA seminar in the months to come.
