WE MAKEBUILDINGSSTAND UP

Structural design, seismic retrofit and forensic review for buildings that carry real load. Every drawing is sealed in-house by the engineer who ran the numbers — no subconsultants, no hand-offs, no surprises at inspection.

FOUR
THINGS
WE DO

Anything outside this list, we will tell you honestly and point you at someone better.

01

STRUCTURAL DESIGN

Steel, concrete and heavy timber from schematic through sealed permit set. We size it, we draw it, we stamp it.

02

SEISMIC RETROFIT

Unreinforced masonry, soft-story and mid-century frames brought up to current code without gutting the building.

03

FORENSIC REVIEW

Cracking, deflection, corrosion. Field investigation, load testing and a report that holds up in a deposition.

04

SITE SUPPORT

Shop drawing review, RFI turnaround inside 48 hours, and an engineer on site when the pour is scheduled.
