Highlights
THE BOTTOM LINE
GPRS safely mapped multiple substation locations for utilities and mapped all underground infrastructure including the grounding grids with zero ground disturbance, providing clearance for safe excavation and construction for the customer without the risk or expense of potholing in a brownfield.

PROJECT APPLICATION
Provide accurate existing subsurface condition documentation, locate the substation grounding grids, and provide clearance for construction excavation in dangerous brownfield environments
ASK
Provide accurate existing condition documentation, identify, and map existing utilities and the grounding grid inside each brownfield substation prior to construction
Task
Provide accurate existing condition documentation, identify, and map existing utilities and the grounding grid for each brownfield substation prior to construction
PROBLEM
- There were no accurate as-builts or records of prior utility findings for the brownfield substations
- Team member safety was the paramount concern due to unknown subsurface infrastructure and the additional risk of brownfield excavation
- The state-provided 811 public utility locating service did not locate private utilities on the substation sites
- It was important to know the exact location of the grounding grids to avoid striking it and damaging the substation's electrical infrastructure
Solution
- GPRS provided comprehensive and accurate utility infrastructure maps and existing subsurface condition documentation
- Private utilities were located and the location of public utilities were confirmed to provide accurate maps and dig clearances
- Locating each grounding grid eliminated the risk of a strike that could damage substation electrical infrastructure and cause injury
- There were ZERO utility or grounding grid strikes on the project
Benefits
- On Time: We kept the project moving with our rapid response, reducing downtime
- On Budget: There was no damage to utilities, saving the client from expensive damage reparation costs
- Safety: GPRS kept all team members safe by preventing dangerous utility or grounding grid strikes during excavation
- Reputation: With no utility strikes on the project, the customer maintains their good reputation
