What Does a Structural Engineer Do?

Structural engineers are the unsung heroes of the built environment. Every building you enter, bridge you cross, and stadium you visit was designed by structural engineers who ensured it would safely support its intended loads.

Core Responsibilities

Structural Analysis

Engineers analyze how buildings respond to various loads including gravity, wind, seismic forces, and live loads from occupants. They use advanced software and engineering principles to ensure structures can safely resist these forces.

Design Development

Working from architectural plans, structural engineers design the bones of a building—foundations, columns, beams, walls, and floor systems. They select appropriate materials and determine member sizes.

Construction Documents

Engineers produce detailed drawings and specifications that guide construction. These documents communicate the design intent to contractors and serve as the basis for building permits.

Construction Support

During construction, structural engineers review shop drawings, answer contractor questions, and may visit the site to observe critical construction activities.

When Do You Need a Structural Engineer?

You typically need a structural engineer for new construction, renovations involving load-bearing elements, additions, investigating building damage, or any project requiring structural permits.
