Structural engineering letters and engineer-of-record transition support are available when an existing-building question needs documented responsibility.
Existing Building · Seismic Retrofit
Seismic retrofit improves the earthquake resistance of existing buildings that were designed to earlier, less stringent seismic codes. Apex Grid provides engineering evaluation of existing seismic systems and designs targeted retrofits — shear walls, moment frames, diaphragm connections, and foundation improvements — that improve performance to current standards or project-specific objectives.
A condition assessment documents the current state of a building's structural system or MEP systems — identifying defici…
A large percentage of existing building projects have no drawings on file. Engineers work through this all the time — us…
Field verification collects the physical data about an existing building that engineering design depends on — member siz…
