Services
Geotechnical Engineering
Our geotechnical engineering services provide comprehensive foundation design and subsurface analysis for commercial and residential projects. We conduct site-specific exploration programs to assess soil conditions and develop appropriate foundation systems. Our engineers deliver cost-effective solutions that ensure structural stability while meeting regulatory requirements.
Subsurface Exploration
We design and implement subsurface exploration programs to identify soil composition, groundwater conditions, and potential geotechnical risks. Our methods include borings, test pits, and in-situ testing to gather accurate data for foundation design and construction planning.
Construction Observation
Our team provides on-site construction observation for foundation work, earthwork, and ground improvement activities. We verify compliance with design specifications, perform compaction testing, and offer real-time solutions for unexpected subsurface conditions during project execution.
Soil Testing Services
Our ASTM-certified laboratory conducts comprehensive soil testing including moisture content, density, shear strength, and hydraulic conductivity analysis. We follow standardized procedures to ensure accurate data for engineering decisions and provide testing services to other consultants and agencies.
Foundation Design
We specialize in designing shallow and deep foundation systems tailored to site-specific conditions. Our approach considers soil bearing capacity, settlement criteria, and structural requirements to deliver safe, cost-effective solutions for residential and commercial developments.
