Core offering

Soil Engineering Construction is a Class A Geotechnical Contractor providing full-service design-build geotechnical construction services across California. The firm is vertically integrated, handling in-house engineering, design, permitting, and construction for slope stabilization, landslide repair, shoring, rockfall netting, retaining walls, foundation underpinning, tiebacks, coastal protection, and underground garages. Projects are delivered as turn-key design-build contracts with internal responsibility for all phases from planning through permit finalization.

Product overview

Soil Engineering Construction is a Class A Geotechnical Contractor providing full-service design-build construction services across California. The company operates as a single integrated offering rather than a modular platform, combining in-house engineering, permitting, and construction capabilities. The core portfolio consists of ten interconnected geotechnical construction services: Slope Stabilization and Landslide Repair, Shoring, Rockfall Netting, Retaining Walls, Geotechnical Engineering, Foundation Underpinning, Permitting Services, Tiebacks, Coastal Protection, and Underground Garages. These services work together as a vertically integrated turn-key approach where the same firm handles structural investigation, plan creation, engineering design, permit procurement, construction, and permit finalization.
