Projects That Perform

Real geotechnical and civil engineering projects across Southern California — from hillside foundations to urban stormwater systems.

Geotechnical

Hillside ADU on Steep Terrain

Beverly Hills, CA

Geotechnical investigation and deep foundation design for an accessory dwelling unit on a steep canyon-facing hillside.

Slopes up to 1:1 (H:V); 24-in. drilled piles to 20 ft into bedrock; 80 pcf soil-creep lateral load

Geotechnical

Post-Wildfire Residential Rebuild

Altadena, CA

Rapid-response geotechnical investigation for a single-family home rebuild in a wildfire burn zone.

Dense alluvial fan soils (115 pcf); Very Low EI (12); rapid mobilization after the Eaton Fire

Geotechnical

Seven-Story Urban Multifamily

North Hollywood, CA

Geotechnical investigation with liquefaction analysis, mat foundation design, and infiltration feasibility for a 7-story, 35-unit apartment building.

Mat foundation on liquefiable soils; 3.7 in. total settlement (static + seismic); infiltration prohibited

Geotechnical

Townhome Duplex Development

Garden Grove, CA

Geotechnical investigation with complex stratigraphy characterization, liquefaction analysis, and groundwater evaluation for a four-unit townhome development.

8 distinct soil layers in 50 ft; mapped liquefaction zone — analysis confirms low susceptibility and zero seismic settlement

Geotechnical

Freeway Corridor Infill Apartments

San Diego, CA

Geotechnical investigation with liquefaction analysis, corrosion testing, and foundation design for a 3-story apartment on a constrained freeway interchange lot.

Rose Canyon Fault Zone (0.89 km); Caltrans CT 643 corrosion testing; 1.7 in. total settlement (static + dry-sand seismic)

Civil

High-Density Urban Apartment — Civil Package

San Diego, CA

Hydrology report, stormwater planter design, and Water Pollution Control Plan for an 8-story, 53,773 SF urban infill apartment.

Zero net runoff increase (Q₅₀ = 1.41 cfs); 7 planter boxes with underdrains; full WPCP

Geo + Civil

Triplex & ADU with Basement Garage

Orange, CA

LID stormwater compliance report for a 5-unit residential development with subterranean parking on a liquefaction-prone site.

DCV = 243 cu-ft; liquefaction zone — infiltration prohibited; 100% capture via lined bioretention

Civil

Coastal Residential Rebuild with LID

La Jolla, CA

LID stormwater compliance report for demolition and rebuild of a single-family home with pool and basement on a compact coastal lot.

WQV = 214 cu-ft on 0.17 acres; dual planter box system (186 SF); 100% capture as Standard Project

Civil

Three-Story Apartment Complex — Grading
