Bridge Inspection

At MAP Infra Group, we take pride in our exceptional bridge inspection capabilities. Our inspectors maintain NHI certifications and are fully versed in the National Bridge Inspection Standards (NBIS), AASHTO guidelines, state DOT regulations, and Element Level Bridge Inspection procedures and requirements. We have developed comprehensive in-house guidelines and summary manuals to ensure consistent and thorough inspections across all structures.

Our commitment to excellence is reflected in the meticulous approach we take to each project. We provide well-trained inspectors, technical support, electronic report distribution, and safe and innovative field equipment to ensure our clients’ specifications are met without compromise.

We conduct detailed load analyses of structures and recommend load posting reductions or repairs as necessary to maintain structural integrity and public safety.

Beyond conducting hands-on bridge inspections, we also evaluate each structure and provide both short-term and long-term maintenance and repair recommendations. This holistic approach assists bridge owners in developing effective asset management strategies, maximizing the lifespan and value of their infrastructure investments.
