A Structural Site Survey (SSS) is performed by a professional engineer to study all exposed and accessible structural elements, including wall studs, floor beams, floor joists, roof system, foundation system, lateral resisting system, and deck framing system. This allows the engineer to best utilize the existing structural elements during the design phase to reduce construction cost for our clients.

The information gathered during Structural Site Surveys, also known as structural as-builts, is incorporated by a licensed engineer into the Structural Drawing Sets and Calculations during the design phase.
If we are not the engineer on record (EOR) of your project, our engineer will provide the SSS markup in PDF format.

SF Bay Engineering performs Structural Site Surveys for projects involving existing structures, including but not limited to Remodeling, Addition, Legalization, ADU, Basement/Garage, Retaining Wall, Foundation, Seismic Retrofit, Deck, Staircase, Pergola and Structural Repairs.
