Size: 240 Buildings Evaluated
Project Status: Ongoing
In 2009 – 2011, MHP conducted a comprehensive seismic risk evaluation of all permanently constructed buildings for Montebello Unified School District (MUSD). The permanent facilities include over 240 buildings on 28 sites. Building construction dates range from the 1930s to the 2000s, and include wood-frame, masonry, cast-in-place concrete, pre-cast concrete, and steel braced frame.
The project included site visits to observe each building, review of original construction drawings, and evaluation of seismic hazards at each site (strong ground motion, fault rupture, and liquefaction). Lateral force-resisting systems were identified and evaluated, and the seismic risk of each building was established. Preliminary cost estimates were developed to allow the district to include seismic hazard mitigation in their capital improvement plans.
MHP is currently completing the designs for seismic strengthening of eight district buildings. Several buildings will be strengthened on a Voluntary basis, and several will be strengthened on a Required basis and will be submitted for Proposition 1D matching funds.
