ConnDOT Biennial Bridge Inspection/Evaluation of Highway Bridges and Sign Supports


Since 2004, HAKS has been providing biennial inspection and evaluation services on up to 250 bridges per year throughout Connecticut. These projects consist of routine and in-depth inspections, including mechanical and electrical inspections of movable bridges; bridges over Amtrak, Metro-North, and other railroads; inspection of overhead sign supports; and analysis of bridges and signs, mast arm inspections, and quality assurance of bridge inspections performed by others.

Tasks include coordination and scheduling; maintenance and protection of traffic; review of inspection files; 100% hands-on inspection of fracture-critical members and fatigue-prone details; non-destructive testing; preparation of Structural Inventory and Appraisal sheets; Element-Level evaluations; documentation of structural conditions in an inspection report using InspectTech software as well as CADD drawings using MicroStation and Bluebeam; and repair recommendations.

During Year 2 of our current five-year assignment (2016-2021), we are finalizing the initial inventory inspections on the Pearl Harbor Memorial (“Q”) Bridge, which carries I-95 over the Quinnipiac River in New Haven. These twin structures are the first extradosed bridges in the US. Previously, we performed semi-final inspections of the two main bridges as well as other structures in the I-95/I-91 Interchange in New Haven.  

Previous contracts included inspection and engineering for the 1.2-mile deck truss Gold Star Memorial Bridge, for which we performed routine and in-depth inspections and monitored frozen rocker bearings, performed gusset plate analysis, developed and installed strain gage monitoring to determine stresses on truss members, and analyzed the results. ConnDOT subsequently implemented emergency replacement of the affected rocker bearings. Our detailed inspection of the Arrigoni Bridge led to an emergency declaration for replacement of the concrete-filled steel grid deck in the two main 660-foot tied arch spans.
