Sacramento Utility Locating Projects that Penhall Worked On

Penhall Technologies locates electrical and water lines

Recently, Penhall Technologies was hired to perform private utility scanning for an engineering firm. The client had been tasked with the demolition and upgrade of large diesel fuel tanks. These provide power to air traffic control relay stations for the Federal Aviation Administration (FAA). Penhall Technologies was asked to locate any major electrical and water lines that were in the area to be cut. The analyst went above what was asked by mapping out any of the grounding grids that were running through the area in addition to the utility markings. This allowed the demolition process to be sped up, keeping the project ahead of schedule and on budget.

Identify all vital utility lines before removing and installing a new playground

Penhall Technologies executed the underground utility locating and provided the customer with a written field report for their records.

Locate and identify patterns of private water lines on residential property

Find and mark PVC pipe connected to buried septic tankA private homeowner in the Napa Valley had a block in PVC line that ran to a septic tank but was not confident in its direction or pattern. The customer called 811 and was instructed to contact a private utility locator. Penhall Technologies completed the survey using GPR and marked out the entire length of the pipe and allowed the customer to trench and replace it successfully.

Practice safe trenching for pipeline work by locating all utilities first

locating utilities before proceeding with constructionIn Sacramento, a general contractor needed to have approximately 14,000 square feet scanned to identify any and all underground utilities prior to trenching for pipeline work. Penhall Technologies completed the work with the use of GPR and RD technology. The utility locating allowed the customer to avoid hand digging to identify utilities and accelerated the projected project completion time.

Ensure that vital utility lines are marked and not hit before undergoing demolition

Prior to the parking lot demolition, the casino wanted to avoid damaging any underground utilities. Penhall Technologies identified which utilities were present and accurately marked their location and direction.
