Pre-Construction Locating Services in Minneapolis, MN

Groundbreaking day is the wrong time to find out what’s under a site. All Clear Locating Services provides pre-construction locating throughout Minneapolis and the Twin Cities metro — a full, site-wide sweep for private and underground utilities, scheduled ahead of your excavation timeline so nothing gets discovered mid-dig.

Unlike a single-line locate, pre-construction locating covers the entire footprint of a project: the full lot, not just the trench line for one addition. That matters for new builds, home additions, and full-lot developments, where crews from multiple trades will be working across the same ground over weeks or months.

We coordinate directly with your project timeline, and for projects that need permit-ready documentation, we pair the locate with RTK GPS utility mapping so your engineer and every subcontractor are working from the same verified data.

This kind of locate is also different in how it’s scheduled. A single-line locate can often be booked a day or two out. A pre-construction sweep needs to be planned into your project timeline early enough that permitting, engineering, and the first day of excavation aren’t waiting on us — which is why we work directly with builders and developers to lock in a date well before the crew mobilizes.

What Is Pre-Construction Locating?

Pre-construction locating is a comprehensive, site-wide utility sweep completed before groundbreaking, rather than a locate limited to one specific trench or work area. It’s built for projects where:

  • Multiple areas of a lot will be disturbed over the course of construction
  • Several trades or subcontractors will be excavating at different points in the timeline
  • Permits or engineering plans require documented underground conditions
  • The site has an unclear history of past private utility installations
Why Schedule Pre-Construction Locating Before Groundbreaking
  • Fewer mid-project surprises. Finding a private line after excavation starts means a stop-work delay. Finding it beforehand means it’s just part of the plan.
  • More accurate budgeting. Known underground conditions reduce the risk of change orders once digging starts.
  • Smoother permit and inspection process. Documented locates support the underground conditions sections of many permit applications.
  • One locate for the whole project. A full-site sweep means every trade works from the same marked ground instead of scheduling separate locates as work moves across the lot.

What We Look For During a Pre-Construction Sweep

A full-site sweep goes beyond the immediate footprint of the planned structure. Depending on the property, we’re checking for:

  • Private lines left over from a previous structure, driveway, or outbuilding on the lot
  • Irrigation and invisible fencing that may not appear on any survey or plat
  • Utility easements and crossings that affect where equipment can safely operate
  • Older septic or well infrastructure on lots that have since connected to city service
  • Any conflict between the planned excavation and existing private utility routes

Catching these before groundbreaking is the entire point — it’s far cheaper to redesign a trench route on paper than to redirect a crew that’s already mobilized.

Our Pre-Construction Locating Process
Step 1 — Project & Site Plan Review

We review your excavation plan, site boundaries, and known utility records to understand the full scope of what needs to be located before anything is marked.

Step 2 — Full-Site Utility Sweep

Using electromagnetic detection and GPR, we trace and mark private and underground utilities across the entire project footprint, not just a single planned dig area.

Step 3 — Documentation & RTK GPS Records

On request, we log utility positions with RTK GPS mapping, giving your engineer, permit office, and subcontractors a shared, survey-grade reference for the site.

Step 4 — Coordination With Your Excavation Timeline

We schedule around your groundbreaking date and can return for follow-up verification as different phases of the project move forward.

Who Needs Pre-Construction Locating

New Home Builders

Ground-up residential builds need the full lot cleared before foundation and utility trenching work begins.

Additions & Remodel Contractors

Additions, garages, and major remodels often disturb ground that hasn't been touched — or documented — since original construction.

Developers

Multi-lot residential and commercial developments need consistent, documented locates across every parcel before phased construction begins.

Municipalities

Public infrastructure and roadway projects use pre-construction locating to identify private utility crossings before public work starts.

FAQS

A standard locate typically covers one work area or trench. Pre-construction locating covers the entire project footprint before groundbreaking, so every trade is working from the same cleared ground.

We recommend scheduling as soon as your excavation timeline is set, ideally a week or more before groundbreaking, though we work to accommodate tighter schedules when possible.

Yes. We can provide site documentation and, on request, RTK GPS-mapped records suitable for permit applications and engineering coordination.

Yes. We regularly support developers who need consistent, documented locates across multiple parcels ahead of phased construction.

We can return to extend coverage to new work areas or re-verify marks as your project evolves — just let us know as plans firm up.
