Inspection & Lab

Construction Material Inspection & Testing

With our staff of competent engineers, experienced inspectors and knowledgeable researchers, and our certified construction material laboratory, AID is a reliable partner for material QC/QA testing and construction inspection.

Our laboratory is AASHTO-certified for a wide variety of asphalt, concrete and soil tests. In addition to providing standard material testing and construction inspection services, our specialized experts and researchers can interpret the results and provide useful conclusions and solutions. Additionally, we offer traffic control services, available for same-day service throughout the region. We provide services across New Jersey and the Mid-Atlantic surrounding states.
