To confirm compliance with our engineering recommendations, we are commonly retained to perform testing and inspection services during construction. Our field technicians and inspectors maintain current certifications including ICC, NICET, ACI, and Caltrans.
Our laboratories maintain current accreditations including:
• AASHTO AMRL
• CCRL
• DSA
• USACE
• Caltrans
Testing on soil, aggregate, asphalt concrete, and Portland cement concrete is performed in accordance with published test procedures such as ASTM, Caltrans, USACE, AASHTO or the governing building code. We typically provide construction inspection services in the following areas:
