 United States Navy
Fracture Critical, Above Water and Underwater Bridge Inspections
Infrastructure Engineers was selected for a second cycle
to perform bridge inspections in Guantanamo Bay Cuba, through their on-call contract with the US Navy. Two of the bridges on the military base are fracture critical. Since there are no bridge access vehicles on the base, Infrastructure Engineers’ engineer-climbers will utilize rope access techniques to complete a hands-on inspection of the structures. In addition, these same inspectors, who are also commercially certified (ADCI) divers will perform the underwater inspection of the bridges. Access to the base is difficult and requires weeks of planning to insure that all equipment and personnel arrive without delay so that the work can be completed. Having engineer-bridge inspectors, who are trained in rope access techniques and commercially trained in diving, provides an advantage for inspecting challenging structures by reducing costs to clients like the US Navy.
