When there are uncertainties surrounding a structural, architectural, or materials issue, testing is a crucial step toward understanding its scope and source. Traditional testing methods, though often effective, can be physically intrusive, time-intensive, and costly. Alternately, nondestructive evaluation methods allow for the assessment of as-built conditions, material properties, and distress in a component or system without altering or damaging its form. These methods can be used in lieu of or as a supplement to traditional testing to provide valuable information while minimizing the extent of destructive testing.
WJE has pioneered the use of nondestructive evaluation methods such as ground penetrating radar, impact echo ultrasonic testing, half-cell corrosion potential surveying, and infrared thermography in civil, structural, and architectural investigations. WJE’s depth and breadth of experience evaluating thousands of structures and materials using nondestructive methods is unmatched.
From identifying complex reinforcement placement and internal flaws in nuclear power structures to detecting air leakage and moisture infiltration in historic building envelopes, WJE offers a wide range of nondestructive evaluation options to efficiently diagnose issues that otherwise may require expensive and disruptive exploratory openings and testing to detect and correct.
In addition to minimizing costs and time spent out of service, nondestructive evaluation techniques allow WJE engineers to gain a broader understanding of a structure’s condition and performance—information WJE uses to develop better targeted and more effective recommendations for clients.
