Services
Forensic Structural Engineering
We investigate structural failures and material defects using non-destructive testing and advanced diagnostics. Our engineers analyze concrete, masonry, and steel systems to determine root causes of distress, corrosion, or collapse. Clients receive actionable repair recommendations aligned with code requirements and budget constraints.
Building Enclosure Commissioning
Our team evaluates building envelopes for water leakage, air infiltration, and thermal performance issues. We conduct hygrothermal modeling, field testing, and construction-phase quality assurance to optimize durability and energy efficiency for new and existing structures.
Geotechnical Forensics
We diagnose foundation settlement, pavement failures, and slope instability through subsurface exploration and laboratory testing. Our geotechnical experts develop remediation plans for problematic soils and provide construction monitoring to ensure site-specific solutions.
Non-Destructive Testing
We employ impact-echo testing, infrared thermography, and ultrasonic methods to assess structural integrity without damaging materials. This approach identifies hidden defects in concrete, masonry, and steel systems while minimizing client disruption.
Hygrothermal Analysis
Using WUFI software, we simulate heat and moisture transfer in wall and roof assemblies. This analysis informs vapor retarder placement, condensation risk mitigation, and energy-efficient retrofit strategies tailored to climate-specific conditions.
