Transmission Line Construction Inspection & Oversight

Independent inspection for new transmission lines, rebuilds and upgrades, from right-of-way through energization, on lines up to 500kV.

Transmission Line Inspection From Right-of-Way to Energization

Transmission line construction stretches across miles of right-of-way, landowners, access roads and crossings, with crews working far from the owner’s office. Foundations, structures and conductor work all have to meet tight tolerances, and problems that slip through are expensive to fix once a line is energized.

RGC Power Group provides independent transmission line construction inspection and oversight for the owner. Our construction managers inspect every phase against the approved plan and profile, drawings and specifications, document progress daily, and keep you informed about what is happening in the field, on lines up to 500kV.

We support investor-owned utilities, electric cooperatives, municipal utilities and large-load interconnection projects across Texas, Oklahoma, New Mexico, Kansas and Colorado.

What We Inspect on Transmission Line Projects

Our transmission line inspection covers each stage of construction, so defects are caught before they are buried, bolted up or energized.

Right-of-Way & Access

Clearing, access roads, matting, erosion control and landowner commitments, verified against permits and environmental requirements.

Verified & Documented

Survey & Staking

Structure locations and centerline staking coordinated with surveyors and checked against the plan and profile before work begins.

Verified & Documented

Foundations

Drilled piers, direct-embed and anchor installations inspected for depth, reinforcing, concrete placement and tolerance.

Verified & Documented

Structure Assembly & Erection

Steel and wood structures, crossarms, insulators and hardware assembled and set to the framing drawings and torque requirements.

Verified & Documented

Conductor & OPGW

Wire stringing, sagging, clipping, splices and dampers inspected, with clearances verified at crossings and spans.

Verified & Documented

Grounding & Cleanup

Structure grounding, counterpoise, restoration of the right-of-way and final punch list items documented before turnover.

Verified & Documented

Transmission Construction Phases We Oversee

A consistent process keeps long, linear projects on schedule and well documented.

01

Preconstruction

Contract and design package review, constructability review, outage planning, and survey and staking coordination.

02

Foundations

Daily inspection of foundation installation with depth, material and quantity documentation at every structure.

03

Structures & Wire

Assembly, erection, stringing and sagging inspected and photographed, with daily progress and safety reporting.

04

Energization & Closeout

Final inspections, punch lists, as-built drawings, right-of-way restoration and turnover documentation.

Why Owners Use Independent Transmission Inspection

RGC doesn’t build transmission lines. We work for the owner, so our only interest is that yours is built right.

Eyes on Every Mile

Our field construction managers cover the line so the owner knows what is happening at each structure, not just at the yard.

Accurate Quantities

Unit-price work is verified and documented daily, so invoices and change orders match what was actually installed.

Fewer Surprises at Energization

Foundation, framing and conductor issues are caught and corrected during construction, when they are still inexpensive to fix.

Available 24/7, including emergencies

A transmission line construction inspector represents the owner in the field. They verify that right-of-way work, foundations, structures and conductor installation match the approved plan and profile and specifications, document quantities and progress daily, and flag safety and quality issues to the contractor and owner.

RGC inspects transmission construction on lines up to 500kV, as well as sub-transmission and distribution work.

Yes. We inspect new construction, rebuilds, reconductoring and structure replacement projects, including work performed around energized facilities and outage windows.

Our field construction managers deliver daily progress reports with crews, equipment, structures completed, quantities, safety observations, and photos and video, so you can follow the project without being on the line.

RGC is based in Canyon, Texas and inspects transmission projects across Texas, Oklahoma, New Mexico, Kansas, Colorado and the surrounding region.
