Structural engineers specialize in the design of buildings, including residential housing.

Whenever there are modifications or repairs done to existing construction, or framing for additional space, a structural engineer will be part of the picture. Their services also are needed for altering roof structures, such as adding trusses.

Structural engineers can be contracted through the architect or builder, but often the homeowner contacts an engineer directly. When doing so, it's important to make sure the structural engineer is registered, professionally licensed through the state.

What Does a Structural Engineer Do?
The structural engineer will make a site visit to evaluate the desired modifications, look at original structure plans, and assess the impact. Depending on the project, he'll do some measuring, and possibly some surveying, particularly if perimeter drainage issues are involved or if soil has washed away from the foundation.

Each construction project requires a structural engineer to employ different research. Factors such as wind speed, snow loads and occupancy loads must be considered along with the plans detailed in the architectural drawings.

What Should You Discuss with a Structural Engineer?
Before the site visit, homeowners should know exactly what kind of construction project they want as well as how quickly they would like it done.
