An associate of LCR&A was directly involved with the initial design and testing of instrumentation systems for three adjacent spans of a segmental box-girder bridge being built in the downtown area of the city of San Antonio, Texas. Innovative instrumentation systems were developed for measuring span deflections and forces in external tendons. A battery-operated, multi-channel, automated data acquisition equipment was designed and tested for each instrumented span, to ensure the long-term reliability of the instrumentation system.
