- Inspection and Testing
Plans for a new station were already underway when a fire destroyed the existing station.
The Leighton Solution.
Leighton completed a geotechnical exploration to provide subsurface data to develop foundation design. Liquefaction analysis of the soil profiles was conducted using CPT data and a site-specific peak horizontal ground acceleration. We determined that the potentially liquefiable soils are relatively thin and overlain by relatively thick non-liquefiable material, so surface manifestation of liquefaction in the form of sand boils and ground fissures is expected to be low. The new fire station was designed to be supported on a shallow, mat foundation system.
During construction, Leighton provided geotechnical observation and testing of building pad preparation, site grading, trench backfill, and placement of aggregate base and asphalt concrete. Leighton also provided special inspection and testing of concrete, high strength bolts, fireproofing and welding.
