Structural Stamping Services
Apex Grid Engineering provides structural stamping services across 49 states and the District of Columbia — structural drawings and calculations reviewed in responsible charge by licensed structural engineers and sealed for permit. Foundations, floor and roof framing, lateral force-resisting systems, and connection details are engineered for each state's governing loads — wind, seismic, snow, expansive soils — with a traceable load path from roof to foundation on every sealed set. Veteran-owned, 10+ licensed professional engineers, and plan-check correction support included on every stamping scope.

What structural stamping covers
Foundation plans and details coordinated with the geotechnical report, floor and roof framing, the lateral force-resisting system, anchorage and connection details, and the sealed structural calculations behind them. The engineer of record confirms the load path is complete and traceable before anything is sealed — that continuity is the first thing a plan reviewer checks.
- Foundation design with geotechnical coordination
- Floor, roof, and lateral framing with connection details
- Sealed calculations with a traceable load path
- Plan-check correction responses on sealed sheets
Engineered for each state's governing loads
Structural stamping is never generic: Gulf Coast projects are engineered for hurricane wind, California and Pacific Northwest work for seismic, northern states for snow and frost, and expansive-clay regions for foundation movement. Each state page below details the local loads, soils, and plan-review expectations the sealed design answers to.
Review-and-seal, not stamp-for-hire
Apex Grid's structural engineers define the scope, review the design basis, and perform or verify the structural work before sealing. Drawings from other firms are sealed only after independent responsible-charge review — unverifiable structural documents are not sealed, and the project team is told exactly what is missing.
Licensed coverage: 49 states plus the District of Columbia
