Services
Geotechnical Investigations
Our geotechnical investigations assess subsurface conditions through test borings, rock coring, and infiltration testing. We evaluate soil and rock behavior to inform foundation design, slope stability, and groundwater control measures. Data from these studies supports cost-effective engineering solutions tailored to project-specific challenges.
Foundation Design
We provide shallow and deep foundation design services, including settlement analysis and lateral earth pressure calculations. Our engineers develop customized solutions for residential, commercial, and industrial structures, ensuring stability in challenging soil and groundwater conditions across diverse project types.
Environmental Consulting
Our environmental consulting includes Phase I/II site assessments, remediation planning, and regulatory compliance support. We help clients address soil and groundwater contamination, manage imported/exported fill materials, and navigate environmental liabilities throughout project lifecycles.
Construction Inspection
We offer full-time construction inspection for earthwork, foundation, and retaining wall systems. Our technicians verify material quality, supervise contractors, and conduct field tests to ensure adherence to design specifications and safety standards during all construction phases.
Soils Laboratory
Our in-house soils laboratory performs sieve analysis, permeability testing, and California Bearing Ratio assessments. These tests establish soil design parameters and verify construction compliance with project specifications, supporting accurate engineering decisions and quality control.
