Services
Materials Testing
Our materials testing services evaluate concrete, cement-based materials, polymers, and metals using advanced techniques like petrography and scanning electron microscopy. We provide ASTM and AASHTO-compliant testing for durability, chemical composition, and structural integrity. Clients rely on our data for forensic analysis, quality control, and failure prevention in construction projects.
Structural Engineering
Structural engineering services include analysis, design, and risk assessment for buildings, bridges, and industrial systems. We perform static and dynamic testing to ensure compliance with safety standards and regulatory requirements. Our experts address fatigue, corrosion, and environmental degradation to optimize structural longevity.
Building Science Consulting
Building science consulting focuses on energy efficiency, sustainability, and envelope performance verification. We assess mechanical systems, building codes, and environmental impacts to create high-performing structures. Services include commissioning and forensic analysis for moisture intrusion or thermal inefficiencies.
Concrete Analysis
Concrete analysis covers mix design, durability testing, and failure investigation for cast-in-place and precast structures. Our experts develop high-performance solutions like ultra-high-performance concrete (UHPC) and fiber-reinforced concrete. Petrographic examinations identify issues such as alkali-aggregate reactions or sulfate attack.
Nondestructive Evaluation
Nondestructive evaluation uses ultrasonic, radiographic, and vibration analysis to assess structural integrity without damage. We deploy portable equipment for on-site testing of bridges, rail systems, and industrial facilities, providing real-time data for maintenance and safety decisions.
