What do Structural Engineers do?

We are the people behind the scene who deal with the stress and strain of your house or other structure.  We work with steel, concrete, wood, and masonry.  We make sure that your house can stand up to mother nature whether it be snow, wind, or earthquake.

Unlike the Architect who uses creativity to design your living space, we use our computers to make mathematical models of the basic framing.

The models are then used to determine the loads and stresses on each member. The stresses are subsequently checked to determine if they are allowed by the various design codes.
