Factors affecting engineering costs in Orange include drive-thru canopy size and dual-lane configurations, grease interceptor installations requiring floor structural modifications, second-story dining areas requiring elevated floor systems, and existing building conversions requiring extensive structural analysis.

**Challenge 1: Heavy Kitchen Equipment Loads** Commercial kitchen equipment including fryers, grills, hood systems, and walk-in coolers create concentrated floor loads exceeding standard commercial construction requirements.

**Solution:** We design reinforced concrete floor slabs with increased capacity for kitchen areas. Floor systems typically support 150-250 PSF live loads accommodating heavy equipment. Equipment locations coordinate with structural design providing proper support. Seismic anchorage meets California requirements preventing equipment displacement during earthquakes protecting operations and safety.

**Challenge 2: Drive-Thru Canopy Wind Loads** Drive-thru canopies create exposed structures subject to significant wind loads while providing weather protection for customer vehicles and menu board equipment.

**Solution:** Our canopy designs use steel or aluminum framing with proper wind resistance for Orange County coastal and inland wind conditions. Foundation systems resist overturning forces from lateral loads. Canopy structures support menu boards, lighting, and payment systems with proper seismic bracing. Column placement accommodates vehicle circulation and clearances.

**Challenge 3: Grease Interceptor Integration** Health code requirements mandate grease interceptors for commercial kitchens requiring floor penetrations, structural support, and proper drainage slopes creating structural coordination challenges.

**Solution:** We design floor systems accommodating grease interceptor installations with proper structural framing around openings. Floor slopes direct drainage to interceptors and floor drains. Structural coordination with plumbing systems ensures compliant installations. Access provisions allow interceptor maintenance without structural interference.

**Challenge 4: High-Traffic Floor Durability** Fast food restaurants experience intensive foot traffic, equipment movement, and cleaning operations requiring durable floor systems resisting wear and moisture damage.

**Solution:** Our structural designs specify appropriate concrete mixes and surface treatments for restaurant environments. Floor slabs include moisture barriers protecting against water intrusion. Proper drainage slopes prevent water accumulation. Joint design and spacing minimize cracking maintaining floor integrity through intensive operations.
