Private utility locating in Chicago

Pinnacle Utility Locating is a private utility locating company in Chicago, IL. We find and mark privately owned electric, gas, water, and communications lines that 811 does not cover across Chicago.

Ground penetrating radar

GPR in Chicago scans for non-conductive pipe, voids, and unknown subsurface features when electromagnetic locating is not enough — on parking lots, yards, and unpaved sites throughout Chicago.

Utility mapping & as-builts

Utility mapping in Chicago turns field marks into CAD or GIS so Illinois GCs and owners keep a record instead of re-locating the same site from scratch.

Concrete scanning

Concrete scanning in Chicago maps rebar, conduit, and post-tension cable before core drilling or saw cutting so Chicago interior and structural crews can cut with a clear window.

Damage prevention programs

Damage prevention in Chicago combines 811 ticket review, private locates, and documented marks so multi-site owners get one standard across Chicago instead of surprise strikes.

How we work

A five-stage delivery process

Predictable execution from first ticket review to documented closeout — at every stage.

  1. 01

    Ticket & site review

    We review the 811 ticket, as-builts, and access, then walk the property to confirm what public marks miss before quoting.

    Scope & proposal

    You receive a written scope with methods, coverage area, deliverables, and pricing — typically within 48 hours.

  3. 03

    Field locating

    Crews apply EM, GPR, and concrete scanning as specified and paint APWA color-coded marks on the ground.

  4. 04

    Mapping & records

    Marks are documented with photos, sketches, or CAD/GIS mapping so the next crew is not starting from zero.

  5. 05

    Closeout

    You receive locate records, maps, and a documented closeout your superintendent can file with the job.

FAQ

Chicago locating questions

Who is a licensed utility locating company in Chicago?

Pinnacle Utility Locating is a licensed and insured private utility locating company serving Chicago. Local crews handle electromagnetic locating, GPR, mapping, concrete scanning, and damage prevention to the same national standards we use in every market.

Do you locate private utilities that 811 does not mark in Chicago?

Yes. Our Chicago crews locate privately owned electric, water, comms, irrigation, and process lines on the customer side of the meter — the lines public one-call tickets leave unmarked.

Do you offer GPR and concrete scanning in Chicago, IL?

Yes. We provide ground penetrating radar, concrete scanning, and utility mapping throughout Chicago. Methods are written into the proposal so they match soil, surface, and the utilities on site.

Do you map locates for the next crew in Chicago?

Yes. After we mark the ground, we can document findings with photos, sketches, or CAD/GIS so Chicago GCs and owners keep a record instead of starting over on the next visit.

Do you serve areas outside Chicago?

Yes. Our Chicago crews cover Chicago and surrounding communities throughout the Illinois metro. For properties farther out, we confirm coverage during the site review.

How soon can you assess a property in Chicago?

Most Chicago site reviews are scheduled within a few business days, with a written locating proposal typically delivered within 48 hours of the walkthrough.

How quickly can you provide a proposal?

Most commercial proposals are delivered within 48 hours of the site review. Multi-site or mapping programs may take slightly longer because each location is scoped for access, methods, and deliverables individually.

Do you locate utilities that 811 does not mark?

Yes. Public one-call marks the utilities that member companies own. Privately owned electric, water, comms, irrigation, and process lines on the customer side of the meter are our primary work — and the lines most often hit.

Are you licensed, insured, and able to meet vendor requirements?

Our crews carry general liability and workers' compensation coverage in the markets where they operate, and we regularly complete vendor onboarding, insurance certificates, and safety documentation for GCs, industrials, and property managers.
