Master Locators was part of a construction project of new buildings at the Cedar Crest Lehigh Valley Hospital. Master Locators provided pre construction services on this project.
Master Locators started off this project by locating the outside vault walls and wall thickness, which took two full days of air vacuum excavation work. Prior to conducting the vacuum excavation, Master Locators placed a One Call to come mark out any public utilities that might be inside the walls. Because the vault was rectangular, four test pits were required to expose the outer walls; one test pit per wall. To obtain the wall thickness, Master Locators used a laser measuring device and a tape measure to locate the distance from the manhole lip to the inner wall of the vault. Master Locators calculated the wall thickness by subtracting the inner dimension from the outer dimension during vacuum excavation. Master Locators saw cut through the concrete and used vacuum excavation to remove the dirt present, and repaired it with cold patch after after the outer wall of the vault was exposed. The total time for exposing and repairing these vault walls was two days. During the excavation, a representative if PIDCOCK was on site to collect vertical and horizontal survey information.
Master Locators provided Quality Level A Data to locate a UGI gas line that was located in front of the Jaindl family pavilion. This required one day of vacuum excavation to locate and expose the utility. Prior to conducting the vacuum excavation, Master Locators placed a One Call to locate the line, and coordinated with UGI representatives to mark out and confirm the location of the suspected gas line. During the excavation, a representative if PIDCOCK was on site to collect vertical and horizontal survey information.
Within the 14 acre area of the scope of work, Master Locators scanned for all locatable utilities and performed test pits to provide Quality Level A data on the existing utilities. Following locating the utilities, Master Locators provided surveying and AutoCAD services to incorporate all field findings into an existing client provided AutoCAD basemap.
Master Locators returned to the same site a second time to provide further vacuum excavation services on the same project, this time for the purpose of locating a tunnel. We saw cut and exposed a trench approximately 3 feet 4 inches long x 1 foot 6 inches wide to expose the side of the tunnel. We exposed the edge of the tunnel running under the water line. Our technicians felt the edge of the tunnel but could not expose to confirm as a visual. Per the client’s request to get a depth on the tunnel, we exposed the tunnel at a depth of 8 feet 6 inches.
