Hydraulic Structure Evaluation

Bridge deck preservation is a critical part of any asset management program but it comes with challenges like traffic disruption, complex data collection, and evolving reporting requirements. BDI addresses these with a comprehensive suite of Nondestructive Evaluation (NDE) techniques that provide vital information to bridge owners such as location and extents of defects and underlying deterioration mechanisms, while minimizing impact to the traveling public. Whether supporting planned maintenance, emergency response, or compliance with DOT mandates, BDI delivers timely, actionable insights. With over 100 million square feet inspected for 24 state DOTs, we bring proven expertise, scalable solutions, and trusted project management to every bridge deck evaluation.

What Can We Do?

BDI applies traditional evaluation and advanced nondestructive evaluation (NDE) techniques to extract critical information to deliver advanced insights into hydraulic structures. Our team provides expert guidance to define the appropriate NDE scope, always selecting the best tool for the job.

Throughout all investigations, we seek to gather information required for you to make informed decisions. Depending on request results could include:

  • What can we do?

Configuration

Condition

BDI can determine dimensional data, including concrete or steel thickness, steel reinforcement layout and depth, and other dimensional data using a combination of Visual inspection, UT/UTT, Phased Array, GPR and HRI. In addition BDI determines loading conditions and configurations special to hydraulic structures such as Post-tensioned trunnion anchor rod in situ force (ADM)

BDI will work with owners to determine the extent of condition assessment required to make informed decisions and tailor an approach based on this. Regardless BDI can determine a variety of information including:

  • Location and extent of delamination, previous repairs, voids, spalls, defective welds, cracked welds, and other defects in line with relevant industry standards using GPR, HRI, SounDAR, IR, MIRA, UPV, SE-IR, UT, UTT, Phased Array, MT, and MFL.
  • Precursors to deterioration and potential for corrosion of reinforcement using GPR, HCP, and ER.
  • Trunnion Deadman Anchor Rod Integrity using ultrasonic wave from a single transducer (straight-beam, angled-beam, phased array - Photos 5

    • What We Deliver

    BDI delivers comprehensive evaluation packages that include detailed visual inspection documentation, high-resolution condition maps, and aggregate statistics with result tables derived from both NDE and visual methods. These deliverables provide clear, actionable insights to support structural assessments, maintenance planning, and compliance with industry standards.
