Coordination with pre-engineered building manufacturers and foundation design for the region's expansive soils require specialized expertise.
Seismic Design Requirements
Fontana's location in Seismic Design Category D requires sophisticated seismic design for all steel buildings. The California Building Code prescribes specific requirements for lateral force-resisting systems, including:
- Special moment frames (SMF) with capacity-designed connections
- Height and configuration limitations
- Diaphragm design requirements
- Foundation seismic load transfer
Our engineers apply current seismic provisions and design cost-effective lateral systems that achieve code compliance while minimizing construction cost. Seismic design often represents 15-25% of total structural cost for Fontana industrial buildings, making efficient design critical to project economics.
Foundation and Soil Considerations
Fontana's alluvial soils present variable conditions ranging from dense gravel to expansive clay. Geotechnical investigation is required for all industrial construction, and foundation design must address:
- Potential for differential settlement
- Expansive soil mitigation
- Groundwater conditions
