NONDESTRUCTIVE EVALUATION (NDE)

EVALUATING EXISTING STRUCTURES AND MATERIALS WITH INNOVATIVE SOLUTIONS

What is NONDESTRUCTIVE EVALUATION (NDE)?

IDENTIFY VULNERABILITIES, REDUCE RISKS, AND IMPROVE YOUR ASSET MANAGEMENT PROCESSES.

Our structural nondestructive evaluation (NDE) division is equipped with a wide range of specialized and innovative technologies for evaluating the in-situ condition of a structure and materials.

Innovative Solutions

Deck Acoustic Response (DAR) System

Identify delaminations and other defects in bridge decks and other concrete structures with automated acoustic testing. Refined models built on considerable validation data power the high-speed analytics behind the defect mappings that SounDAR produces, ensuring accurate repair estimates and fast turnaround in reporting.

Multiphase Approach to bridge deck NDE

Co-developed by BDI & Infrasense

Aerial imaging by UAV, high-speed vehicle-based structural nondestructive evaluation (NDE) scanning, and traditional testing methods strategically combined to deliver quantitative information for improved asset management.

Structural and Subsurface Spillway Inspection Services

MITIGATING RISK AND MAINTAINING PUBLIC SAFETY BY PROVIDING DAM SPILLWAY OWNERS WITH A FULL ASSESSMENT OF THEIR STRUCTURE

Fusing multiple structural nondestructive evaluation (NDE) techniques and deploying efficient data collections methods, spillway owners can receive a detailed and complete mapping of both the integrity of the spillway structure itself and the geophysical conditions below the spillway.
