Washington DC Utility Locating Projects that Penhall Worked On
Scan first to avoid hitting electric lines
Recently, a local plumbing company hired Penhall Technologies to locate an electric line that was struck during digging operations. The client didn’t scan the area initially, so the contractor needed to know where the line entered the building and where to shut it off. The total area of the utility scan was 30’x110’. Within that area, the analyst found (12) electric lines and (1) water line. The analysts used the Sir 3000 with a 400 MHz antenna to scan the areas and followed up by performing sweeps with our electromagnetic detection device (RD 8000), which will pick up any live power or communication lines.
Penhall Technologies reveals man holes that were previously unknown to help customer find out issues regarding their water supply
Last week, Penhall Technologies had a utility locating job in Washington, D.C. at the National Mall. The water supply to one of the concession stands on the Mall was turned off or blocked. The client had hired numerous companies to come out and investigate, but they could still not figure out what was causing this. The analysts’ job, was to locate the water line and map out the different directions it was heading. The client wanted to know the direction of the blockage, to know where to inspect for damage. Using spray paint, the analysts accurately marked out the water line in numerous directions. We verified our results because the lines led to numerous manholes with water line markings. These client had no previous knowledge of the manholes.
