Consult & Design

Our goal is optimized design with reduced construction cost. Very often minor adjustments during the preliminary design phases lead to a simplified structural frame, and therefore a cost-effective design.  As well, we have the expertise to assess the practicality of any design, taking into consideration both structural feasibility and City Code allowances.
