Services
Building Envelope Investigation
Our forensic engineers conduct comprehensive assessments of building envelopes to identify moisture intrusion, thermal inefficiencies, and structural vulnerabilities. Using infrared thermography and ASTM-standardized testing, we diagnose root causes of failure in roofing systems, waterproofing membranes, and facade components. Recommendations prioritize cost-effective solutions that extend building lifespan while maintaining code compliance and energy efficiency standards.
Roof Design Consulting
We develop customized roofing solutions balancing performance, aesthetics, and budget considerations. Our designs incorporate sustainable materials and energy-efficient systems while addressing specific environmental challenges. From historic preservation to new construction, our team creates detailed specifications that ensure long-term durability and compliance with current building codes and industry standards for commercial and institutional structures.
Building Enclosure Commissioning
Our commissioning process verifies that all building envelope components meet design specifications and performance requirements. Through systematic testing of air barriers, waterproofing systems, and thermal controls, we ensure proper integration of roofing, windows, and wall assemblies. This proactive approach prevents costly failures by confirming system integrity before final project completion and occupancy.
Thermal Imaging Analysis
Certified thermographers use advanced infrared imaging to detect hidden moisture and thermal anomalies in building envelopes. This non-destructive testing method identifies heat loss patterns and insulation deficiencies across roofing systems, wall assemblies, and foundation elements. Results guide targeted repairs that improve energy efficiency and prevent structural damage from undetected water intrusion.
Construction Observation
Our field engineers monitor construction progress to ensure adherence to design specifications and industry standards. Through regular site visits, we verify proper material installation, workmanship quality, and compliance with project documentation. This oversight extends from foundation waterproofing to final roof membrane installation, ensuring completed systems perform as designed while maintaining budget and schedule parameters.
