Intelligent Infrastructure Systems is working with the Burlington Country Bridge Commission to design a permanent global Structural Health Monitoring (SHM) system to assist with the Commission’s goal of indefinite preservation for critical infrastructure.

The Commission’s signature long-span structures crossing the Delaware River include the Tacony-Palmyra and the Burlington-Bristol Bridges. The Tacony-Palmyra Bridge connects the Tacony section of Philadelphia, Pennsylvania, and Palmyra, New Jersey and is nearly a mile long, including a 550-foot steel tied arch span and a 260-foot bascule span. The Burlington-Bristol Bridge connects Bristol, PA and Burlington City, NJ and is 3,144 feet in total length with a 540-foot main-span through truss that lifts 75 feet vertically to accommodate large ships. The Riverside Delanco Bridge carries Route 543 across the Rancocas Creek and includes the Commission’s third type of movable structure: horizontal swing bridge.

The design of the SHM system for each bridge will begin with a meeting including Commission Staff and the Engineer of Record to define the desired monitoring requirements, including bridge performance metrics they would like to have monitored. Once consensus regarding the monitoring requirements has been reached, Intelligent Infrastructure Systems will then commence with the preliminary design of the SHM system that includes detailing the type and location of sensors, location of conduit, and identification of enclosures to be used for data acquisition purposes. The next phase of the project - final design of the SHM system - will include the specification of sensor requirements (e.g., material, operation, resolution, accuracy), attachment details, conduit type, and specification of data acquisition and fiber optic networking hardware needed. The design will re-use existing instrumentation deployed as part of the existing SHM system on each bridge, where possible, and anticipate the requisite data interpretation required to translate measured responses into actionable information. The designed system, once installed, will be integrated into the ongoing iCOMPASS project being completed for the Commission that will see the development of web-based portals for viewing of relevant SHM data by Commission staff.
