Scope & limitations
Educational template only. Compare with commercial utility corridor for a similar corridor pattern.
- Setting
- Fleet depot–style paving: aged asphalt, multiple prior trench restorations, active vehicle circulation limited to weekend windows.
- Objective
- Reduce strike risk along a proposed feeder trench by imaging suspect utility crossings and prior patch zones—complementary to applicable public locates.
- Methods
- GPR grids and tie lines across the trench centerline; frequency selected for expected asphalt/build-up thickness; marks at interpreted conflicts with photo context.
- Constraints
- High dielectric contrast from patch mixes masked one shallow target—called out as lower confidence until correlated to a handhole sketch in the limitations section.
- Outcome
- Stake-ready crossing zones plus PDF appendix suitable for the electrical contractor’s dig briefing; explicit interpretive conditions language.
- Lessons
- Early CAD or PDF overlay of trench versus existing islands speeds mark interpretation; EV trench projects often benefit from slab-exit photos even when the scope is “outdoor only.”
