WEST SYLVAN MIDDLE SCHOOL
Seismic Upgrades • Portland, OR
Structural Seismic Retrofit & Roof Diaphragm Reinforcement
West Sylvan Middle School seismic retrofit project involved comprehensive structural seismic upgrades across 70,000 square feet of roof area in Portland, OR. KB Contracting executed roof diaphragm shear sheathing, structural chord strapping, and timber-to-masonry ledger hold-down anchoring to meet modern Oregon seismic resilience codes.
Our specialized seismic framing crews performed structural modifications with surgical precision during school recess periods, installing heavy steel hold-downs, structural plywood shear panels, and continuous rim blocking without disrupting facility operations.
