Master Locators traveled overseas to the beautiful, tropical Caribbean island of Saint Martin as part of a restoration project. The Flamingo Resort on the island had been devastated by Hurricane Irma and was in the process of restoring and rebuilding areas that had been destroyed. Master Locators performed concrete scanning services, private utility locating services and CCTV pipe inspection. In total, Master Locators scanned 27 areas between the two buildings.
How We Did It
The client needed us to locate, or confirm the lack of, utilities beneath a parking lot area designated for the onsite housing for construction personnel. We used concrete scanning to aid structural engineers in assessing the integrity of slabs in the resort buildings. We also located utilities in and around the two resort buildings. Inside the resort, we scanned an area of approximately 4’x4’ in the location of some electrical panels. As a result of the concrete scan, we were able to locate and mark the rebar pattern and conduit found in the concrete.
The next part of the project required our team to provide utility locating services using ground penetrating radar (GPR). We used GPR to penetrate under several different surfaces including sand, asphalt, and concrete. We located communication, electric, and storm lines, and two other unknown utility lines running through the scope. Since the water lines and gas lines were made from plastic, they were unlocatable in the area. Additionally, GPR did not penetrate the asphalt and concrete surface areas well; however, our technician was able to locate a water line for approximately 50 feet.
We then used a CCTV push camera for the purpose of locating a utility line and checking for any potential blockages and location. Our technicians pushed the camera through the main sanitary line to determine the location of the line coming from the pump station and running to the hotel. During the inspection, there appeared to be a second line, but it could be accessed with a 10 foot PVC pipe in a sewage pit. Through our video inspection services, we scanned the entire area around the hotel and proceeded to scan another part of the resort for the main electric line and water main.
