The Challenge


Located in Philadelphia, St. Joseph’s University required Master Locators to perform a majority of our services as part of an extensive project for new construction plans. We traveled to City Avenue where we coordinated traffic control to ensure the safety of all road work. For this project, we handled private utility locating, CCTV pipe inspection, coring and vacuum excavation. The purpose of these services were to confirm the location of utilities that could potentially conflict with proposed inlets and new construction plans, open manholes that were previously unable to be opened, locate the water main under the proposed median, and video inspect the main trunk line to check the condition of the pipes. Through our services, St. Joseph’s University was able to move forward with their construction project.

How We Did It


We started the project by doing core drilling on proposed excavation locations in the right lane of City Avenue to ensure the core bore repair process was followed properly. Following the coring, our air excavation crew performed test holes along City Avenue and 54th Street. The size, depth, material and direction of the lines were confirmed for water lines, communication lines, sanitary sewer, gas lines and electric lines. It was a massive lift that required test holes on approximately 64 utilities that may have conflicted with proposed inlets and new construction, but our team was able to confirm the utilities using ground penetrating radar (GPR) and electromagnetic Scanning (EM). 

To complete the project, Master Locators performed CCTV pipe inspection services on catch basin outlets where the cleanout doors were already opened or were accessible to be opened. We inspected the condition of the catch basin with a push camera, recorded each run, and took pictures. Video inspection services were performed on the main trunk line to check the condition of the pipes and mark the location of lateral pipes. A crawler camera was used to inspect storm and sewer lines, which were were found to be heavily congested with mud and debris.

We provided the client with a field drawing, test hole data sheets, VPI report, engineering report and field service report along with a mark out of all locatable utilities.
