How the work runs
Tenant Improvements
Reconfiguring a commercial space means verifying the existing structure can carry new partitions, mechanical units, and occupancy loads. We assess as-built conditions, design reinforcement where needed, and deliver the stamped drawings required for your building permit and tenant build-out.
Ground-Up Construction
From steel moment frames to concrete tilt-up and wood-frame podium buildings, we engineer the complete gravity and lateral system. Our designs balance constructability and cost while meeting California Building Code and local seismic provisions.
SB 326 & SB 721 Balcony Inspections
California law requires periodic inspection of elevated exterior elements on multifamily buildings. Our licensed engineers perform SB 326 (condos) and SB 721 (apartments) inspections, document findings, and provide the reports and repair recommendations owners need to stay compliant.
