Services
Geotechnical Engineering
Our geotechnical engineering services include subsurface investigations using advanced tools like the Marchetti-type flat plate dilatometer (DMT) to assess soil properties. We provide foundation design recommendations, groundwater analysis, and construction risk evaluations. Our ISO-certified laboratory ensures accurate data for infrastructure projects.
Environmental Assessments
We conduct Phase I and II Environmental Site Assessments (ESAs) to identify contamination risks and prepare Records of Site Conditions (RSCs). Our team specializes in hazardous material identification, remediation planning, and compliance with regulatory standards for property redevelopment.
Materials Testing
Our CCIL-accredited laboratory performs testing on soil, concrete, asphalt, and construction materials. Services include field compaction testing, concrete strength analysis, and asphalt mix evaluation to ensure compliance with engineering specifications and building codes.
Pile Driving Analysis
We offer dynamic pile testing using Pile Driver Analyser (PDA) technology and WEAP/CAPWAP analysis. Our services ensure deep foundation integrity through real-time monitoring and load capacity verification for structural stability.
Building Envelope Diagnostics
Our team inspects roofing systems, concrete structures, and vapor barriers to assess building envelope integrity. We provide condition surveys and maintenance planning for parking garages, bridges, and commercial properties to prevent long-term deterioration.
