Seismic Structural Engineering

What This Engineering Scope Covers

• Seismic design category determination per ASCE 7
• Lateral force-resisting system design — shear walls, moment frames, braced frames
• Diaphragm and collector element design
• Seismic anchorage for mechanical, electrical, and plumbing equipment
• Non-structural component seismic anchorage design
• Seismic retrofit for existing buildings — ASCE 41 procedures
• Soft-story retrofits for multifamily wood-frame buildings
• Unreinforced masonry building seismic evaluation
• Mandatory seismic retrofit program compliance — Los Angeles, San Francisco, Oakland
• Seismic design for high-seismic zones — California, Pacific Northwest, New Madrid

How Apex Grid Handles This

Apex Grid Engineering is a multi-discipline firm with multi-state PE coverage confirmed per project. We provide seismic structural engineering as a standalone service or coordinated with structural, MEP, civil, and geotechnical engineering under one contract. Our engineers produce PE-stamped permit packages that building departments accept — and we respond to plan check comments as part of the scope.
