Bridge and Tunnel Maintenance Projects

  • Bridge and Tunnel Maintenance Projects

Quinn’s experienced professionals, combined with an enduring relationship with the Virginia Department of Transportation (VDOT)  is vitally important on such critical projects as bridge and tunnel maintenance and repairs. Our inspectors work with VDOT to identify areas of a bridge that need repair and to accurately measure, inspect and verify costs for payment of the work.  This work may include chain-dragging bridge decks to identify delaminated areas for patching, sounding substructure concrete, inspecting bearings and bridge joints for deficiencies, and reviewing other items such as concrete cracking and railing conditions.

A recent maintenance and repair project for the Hampton Roads Bridge Tunnel (HRBT) included electrical and mechanical systems. A complete inspection of the systems ranged from the  ventilation to the replacement of fire pumps, motors and piping, floodgate rehabilitation, high voltage feeder cable replacement, and Norfolk water main supply line repair. System maintenance and testing included fire main hydrostatic pressure and flow rate testing, portal floodgate operational testing, and electrical switchgear equipment calibration.

Work is also underway on an emergency repair project to rehabilitate the pavement on the northbound lanes of the  I-664 Monitor-Merrimac Memorial Bridge-Tunnel. The project includes joint repair, concrete removal, patching and painting.
