Statewide Bridge Inspections, Load Ratings, and Acoustic Scanning

Under six consecutive contracts dating back to 2009, Consor has conducted 1,000+ NBIS element level underwater bridge inspections statewide. Each inspection includes a report documenting structural deficiencies, scour conditions, and channel conditions, as well as making pertinent repair and maintenance recommendations to ensure the prolonged safe use of the structure by the traveling public. In addition to diving inspections, we have also provided 2D and 3D acoustic imaging services to fully document scour conditions affecting coastal bridges; acoustic imaging of I-526 over the Wando River won the ACEC-SC Engineering Excellence Award. Emergency inspections, performed during and after flood events, have also been provided to assist in maintaining and reopening vital routes for emergency and commercial traffic. Consor has received multiple perfect scores (500 out of 500) for our work on this contract.

In addition to underwater inspection services, Consor provides NBIS routine, complex, and fracture critical bridge inspections under a statewide task order-based contract. Our topside NBIS inspection contract has included more than 1,000 bridges involving some of the highest profile and challenging inspections in the state. Each inspection includes a visual review of all accessible components, including the substructure, superstructure, and top of the deck. We utilize many different methods of access, including underbridge inspection vehicles, hydro platforms, boats, and even rope access. We have been called upon to provide emergency inspection and emergency repair designs as part of the contracts. Numerous load ratings are also performed under these contracts.
