As-Built Verification
What is As-Built Verification?
Structures with missing plans, undocumented repairs, or suspected construction errors can be difficult to evaluate. BDI’s as-built verification services set out to uncover the truth about how these structures were built in a minimally invasive way, empowering engineers and owners to act confidently and decisively without having to rely on assumptions or risk harming the structure or the traveling public.
What Can We Do
BDI applies traditional inspection and advanced nondestructive evaluation (NDE) techniques to determine critical information for new and existing structures. Our team provides expert guidance to define the appropriate NDE scope, always selecting the best tool for the job. Depending on the makeup of the structure and the nature of its unknowns, BDI offers a variety of services to help quantify critical structural information.

Steel element size configuration including web thickness, presence of shear studs (core concrete deck on steel), inspection of pins, hangers, anchorages, and welds, section loss of steel cables. (See Steel Structures for more information on NDE methods)
What We Deliver
Beyond standard narrative reporting and conclusions, BDI provides:
BDI delivers detailed visual inspections with comprehensive documentation to support structural evaluations, maintenance planning, and compliance tracking. Our process ensures clear, actionable insights through high-quality imagery and expert analysis.
BDI leverages its engineering expertise and knowledge to develop comprehensive reports containing charts, diagrams, and statistics that offer fast and effective communication of results to support decision making.
Understanding the need for our work to be integrated with existing documents and processes, BDI develops its own CAD or works with client-provided CAD to overlay the results of its findings on the structures under investigation.
BDI offers engineering services to evaluate your structure based on the findings of the as-built verification investigation, from related capacity calculations to full evaluation services.
