Structural sheets we stamp
Framing plans, foundation and footing designs, beam and column schedules, load calculations, retaining walls, lintels and headers, connection details, and special-inspection programs — every sheet reviewed against IBC chapters 16–17 and ASCE 7 before it gets sealed.
Calcs or just the seal?
Send complete calculations and we'll review and stamp the set. No calcs yet? Our engineers can produce the structural calculations first, then seal the full package — one team from analysis to permit-ready drawings. Include the geotechnical report when you have one; footing and slab designs ride on it.
What speeds up approval
Clear load paths, stated design criteria (dead/live loads, wind speed, seismic design category), and lateral system callouts on the plans. AHJs reject vague structural sheets — we make sure yours tell the plan checker exactly what the building is doing. Backed by Apex Grid Engineering: 10+ PEs across 49 states.
