RBC Utilities

By the time most teams start thinking seriously about underground utilities, grading, access roads, and laydown areas are already set. That order of operations is backwards. Utility corridors should shape those decisions, not get squeezed in around them.

What Belongs in the Plan Before Grading Starts

Utility corridor routing, decided alongside grading and access, not after it.
Depth and clearance requirements for every scope sharing a corridor, so nothing has to be relocated mid-project.
Locate requests submitted early enough that conflicts surface during design, not during excavation.
A realistic sequence for how water, sewer, storm, and conduit will actually be installed relative to grading and paving.

Bringing a Utility Contractor In Before the Dirt Moves

Loop in the utility contractor while the site plan is still being drafted, not after it's approved.
Confirm corridor routing and depth against grading, access, and laydown plans before they're finalized.
Submit locate requests as soon as the utility layout is stable enough to act on.
Sequence utility installation against grading and paving, rather than assuming they can run independently.
Revisit the plan if site conditions during early grading differ from what the design assumed.

‍

NC 811 locate requests should go in as early as the utility layout allows, since conflicts found during design are far cheaper to resolve than ones found during excavation.

What Happens When Utilities Are an Afterthought

Grading and access roads built without leaving room for utility corridors, forcing costly rework.
Locates requested only once excavation is scheduled, instead of during design.
Utility installation squeezed into whatever sequence is left after every other trade has claimed a slot.
Depth conflicts discovered in the field because corridor planning didn't account for every scope sharing the trench.

Compare RBC's notes on directional boring vs. open-cut trenching, commercial conduit installation, and storm drain pipe installation once method selection becomes part of the early planning conversation.

Questions Civil Teams Ask During Early Planning

How early is too early to bring in a utility contractor?

There's rarely such a thing. A utility contractor reviewing a draft site plan can flag corridor, depth, or access conflicts while they're still just lines on paper, not field problems.

Does early utility planning slow down the site plan approval process?

Generally the opposite. Catching conflicts before submission avoids the resubmission cycles that actually add time to approval.

What does RBC Utilities look for in an early site plan review?

Corridor routing relative to grading and access, depth conflicts between scopes sharing a trench, and whether the sequencing assumed in the plan is realistic in the field. That review is part of how RBC Utilities keeps Carolinas developments moving once construction starts.

‍

The Bottom Line

Underground utilities planned after grading and access decisions are locked in almost always cost more to install and take longer to fix when something doesn't fit. Planning the corridor first changes that.
