Culture


We believe that Senior Leadership should lead through mentorship; that Junior leaders lead through new ideas and engagement. While check-listing can be a quantitative support tool, quality comes from a solid understanding behind engineering decisions. We can be differentiated by many factors but most certainly by the strength of our commitment to your project goals. Ultimately, we understand that we don't meet our goals if we don't meet yours.

Design Philosophy:


We believe that the effective integration of engineered systems into Architecture involves a complimentary approach to suit the aesthetic purpose and the functional needs of a project. The engineering should add value and moderate the use of financial and natural resources in the most practical way possible. The design needs to balance all of the factors involved.


There isn't a singular way to approach all design projects; to choose a prescriptive approach on a wholesale basis means that any given project doesn't achieve our client's goals and may be over-engineered or under-performing. While there is a role for cookie cutter designs, in many cases that's too easy of an approach when your project depends on multiple factors.
