Type: Center-Bearing Swing Span
Location: Hackensack, NJ
Owner: Bergen County
Stafford Bandlow Engineering personnel were responsible for the design and engineering services of this swing span highway bridge in Hackensack, NJ. The bridge was completed, commissioned and placed into service during September 2012, prior to Hurricane Sandy.
Sandy did extensive damage to the bridge electrical systems and SBE was called in by Bergen County to lead the recovery efforts for the bridge. SBE was tasked with surveying and testing the electrical systems to determine the condition of the existing system and evaluate what damage had been caused and what equipment could be salvaged for re-use.
SBE determined that a proportion of the damaged equipment could be salvaged and prepared specifications and procedures for refurbishments. SBE also tested the salvaged equipment and developed specifications for necessary replacement equipment. The refurbishment of the salvaged electrical equipment consisted of:
- Refurbishing motors including; re-winding and re-baking of the motor insulation
- Motor control equipment including; the replacement of motor starters, rewiring and replacement of control system relays and contactor coils and the replacement of damaged enclosures, junction and pull boxes.
In addition to the refurbishments and replacement of equipment, new cabling and raceways were reinstalled, equipment relocated, and the installation hardened to ensure system integrity and protection from similar future storm damage. The redesign work included relocation of equipment to increase their elevation and ensure they would remain above the revised one-hundred-year storm elevation under future catastrophic events.
