Precast insulated wall panels were chosen to meet a critical customer requirement - NORTEL Networks needed to have their building erected and functional as quickly as possible to meet their own product production / scheduling requirements. Construction took place in mid-winter. The selection of precast prestressed insulated wall allowed rapid enclosure of the building thus allowing interior construction to continue free from the harsh winter elements.

The exterior finish on the panels was chosen by the architect and contained several feature reveals to facilitate/encompass a customized unique appearance. An off-white finish was chosen with two textures &endash; smooth sandblasted and exposed aggregate. Coloured accent strips were fastened to the precast panels.

The building's exterior walls were erected in two phases, enabling work on the Phase I interior to take place in conjunction with the installation of Phase II insulated wall panels. This was vital to meet the timeframe established by NORTEL Networks.
