Instrumentation and Monitoring

 

"WJE uses a wide variety of nondestructive evaluation methods and state-of-the-art instrumentation to assess the condition of structures and maintain their integrity over time."

— Robert Hannen, Associate Principal

Distress and deterioration are not always plain to the naked eye. Conversely, visible damage does not always correlate to more serious, widespread issues. Knowing the internal condition or long-term performance of a structure or component is vital to developing appropriate maintenance plans and repair strategies. WJE engages a full suite of state-of-the-art instrumentation and monitoring capabilities to test and measure structures over time and from the inside out.

WJE engineers and architects have instrumented and measured thousands of structures in the laboratory and in the field with strain gages, displacement instrumentation, accelerometers, environmental monitors, and other sensors. WJE has developed, installed, and maintained large continuous monitoring systems, featuring wireless networks, interactive web and video feeds, database archival systems, and automated alarm systems. These techniques and tools provide WJE the detailed information needed to evaluate structural behavior and measure the performance of repairs and retrofits.

Through a data-driven approach to deterioration and distress conditions, WJE engineers and architects give clients a fuller understanding of their structures and can work toward achieving improved performance and increased service life.
