Imagine getting a call from your superintendent that a backhoe just hit an unmarked gas line. The site evacuates. The utility company shuts off service to the neighborhood. Work stops for the day – maybe the week. If you’ve managed commercial construction long enough, you’ve either taken that call or watched someone else take it.
Utility strikes don’t make the news the way crane collapses or structural failures do. But they’re the leading cause of unplanned delays on job sites across the country. According to the Common Ground Alliance, nearly 200,000 utility strikes were reported in 2024 alone, and the real number – including unreported incidents – is estimated at more than half a million. The total cost to the U.S. economy is roughly $30 billion every year.
This guide walks through how to take control of utility coordination from pre-construction through closeout. Not as a compliance checkbox. As a project management discipline.
Why Utility Coordination Is a Project Manager’s Problem
Here’s what the $30 billion number actually means for a project manager. Every dollar spent repairing a direct utility strike carries an estimated $29** in hidden costs, including regulatory fines, road closures, legal claims, and reputational damage. That’s according to data from InfraMarker by Berntsen. A $5,000 line repair can turn into a $145,000 problem before anyone signs a change order.
Most PMs I talk to assume that utility coordination is the responsibility of the utility company or the design team. It doesn’t. The project manager owns the schedule. And when a strike happens, it’s the schedule that takes the hit.
That’s why experienced PMs build GPR scanning into their pre-construction workflow. Ground-penetrating radar detects both metallic and non-metallic utilities, such as PVC, HDPE, and concrete ducts, that traditional electromagnetic locators miss. It gives you a picture of what’s actually underground before the first excavator arrives.
The Utility Coordination Process: A Phased Approach
Utility coordination doesn’t happen in a single meeting or a single phone call. It moves through four distinct phases, each requiring the PM’s attention.
Phase 1: Pre-Construction and Due Diligence
Start before the design is finalized. Call 811 to initiate public utility locates. Gather existing as-built drawings from the utility owners. Conduct a site walk with utility locators to identify visible conflicts. The Federal Highway Administration’s utility coordination and certification guidance recommends beginning Subsurface Utility Engineering work as early as possible. Large projects can need six to nine months for thorough Subsurface Utility Engineering (SUE) processing, so early starts matter.
Phase 2: Design and Conflict Identification
Once you have SUE data at the appropriate quality level, feed it into the design process. The goal is to identify utility conflicts before the project goes to bid. A study published in the ASCE Journal of Construction Engineering and Management found that integrating BIM with real-time field data reduces execution conflicts by 87% and cuts construction costs by 20%**. Those are the kinds of results that justify the upfront investment in proper utility mapping.
Phase 3: Pre-Bid and Contractor Coordination
Utility relocation costs and schedules must be included in the bid documents. If you’re putting together a complete project bid, include a line item for utility coordination. Subcontractors need to know what utilities exist on site, who’s responsible for relocation, and what the schedule looks like. Ambiguity during the bid phase leads to claims during the construction phase.
Phase 4: Construction and Monitoring
Once work begins, hold regular utility coordination meetings. Require a pre-con meeting with every trade that will excavate. Document field changes as they happen. Reviewing as-built conditions through redline drawings ensures the record drawings reflect actual conditions, not design assumptions. A utility that was supposed to be 4 feet down but was found at 18 inches needs to be documented immediately.
Key Tools and Technologies for Utility Coordination
The tools available for utility detection and coordination have improved significantly in recent years. Here are the ones every PM should know about.
Ground Penetrating Radar (GPR) and Subsurface Utility Engineering (SUE)
GPR sends electromagnetic pulses into the ground and measures the reflections from buried objects. Unlike electromagnetic locators, which only detect metallic utilities, GPR detects PVC, HDPE, concrete, and fiber-optic lines. That makes it a reliable single-source detection method for most site conditions.
The numbers back this up. A Purdue University study across 71 highway projects found that advanced utility mapping delivers an average ROI of $4.62 for every dollar spent. And the market continues to grow. The global GPR market was valued at $677 million in 2024 and is projected to reach $1.46 billion by 2034**, with utility detection as the largest application segment, according to Expert Market Research.
811 One-Call Systems
Every construction site should start with an 811 ticket. But here’s what many PMs don’t realize. 811 only marks public utility easements in the right-of-way. Private utilities such as site power, data lines, irrigation, and backup generator feeds are the property owner’s responsibility. The Common Ground Alliance’s 2024 DIRT Report shows that communication cables account for 49% of all damages, and natural gas pipelines account for 39%. Those private lines are a blind spot if you rely only on 811.
Building Information Modeling (BIM) and Digital Twins
The real value in utility coordination today comes from integrating subsurface utility data into BIM models. When you overlay GPR and SUE data onto a 3D model, the entire project team can visualize conflicts before anyone mobilizes. A 2026 case study published in the Journal of Urban and Regional Knowledge found that combining BIM, GIS, and augmented reality for underground utility management reduced execution conflicts by 87% and saved 20% in construction costs**.
Utility Coordination Software
Dedicated coordination platforms like Coordinate PA and vSite from vGIS.io are standard on larger projects. WSB Engineering’s guide on reducing risk highlights how phased relocation plans and coordinated staging, managed through these platforms, reduce field conflicts. The software won’t replace good judgment, but it ensures everyone is working from the same information.
Common Utility Coordination Pitfalls and How to Avoid Them
Even experienced PMs repeat the same mistakes with utility coordination. Here are the most common ones and how to avoid them.
Relying Only on As-Built Drawings
As-built drawings are a starting point, not a guarantee. Utilities get rerouted. Depths change. Trench layouts shift during construction. I’ve seen as-builts show a gas line at 3 feet when it was actually 18 inches below grade. Always verify with field location services such as GPR or SUE before authorizing excavation in any area with known or suspected utilities.
Skipping the 811 Call for Private Utilities
The 811 system covers public utility lines in the street and easement. It does not cover private utilities on the site itself. Site power feeds, data trunk lines, irrigation systems, and backup generator conduits are all outside the 811 scope. Make private utility locating a separate line item in your pre-construction budget, and assign responsibility to the site utility coordinator.
Not Building Contingency Time for Utility Relocation
Utility relocation takes time. INDOT research shows SUE processing can take 6 to 9 months for large projects. If you don’t build that timeline into your schedule, you’ll be waiting for utility clearances while the clock runs on your project completion date. Identify relocations early and start the process before the critical path depends on it.
Poor Communication Between Trades
Electrical, plumbing, data, and fire protection subcontractors all dig in the same trenches. Without coordination, one trade’s excavation can damage another trade’s recently installed line. Hold a utility pre-con meeting before any subsurface work begins. Require each trade to share their planned trench locations and depths. It takes an hour and prevents rework that costs days.
Building a Utility Coordination Plan for Your Next Project
Here’s a practical checklist to build into your next project’s startup process.
- Assign a dedicated utility coordinator. It could be you, an assistant PM, or a field engineer. One person owns the process.
- Conduct an initial utility review during the bidding phase to identify obvious utility risks and constraints. Detailed investigations and utility verification should begin as soon as the project is awarded.
- Include utility coordination as a line item in the project schedule. Give it its own row with start and finish dates.
- Require GPR or SUE scanning before any excavation. No digging without a cleared utility locate.
- Hold a pre-construction utility coordination meeting with all stakeholders. Utility owners, subcontractors, and the design team all in one room.
- Document everything. Photos of locate markings, signed meeting minutes, redline updates, and change orders related to utility conflicts.

Taking Control of Utility Coordination
Utility coordination isn’t the glamorous part of construction project management. But ignoring it is one of the fastest ways to blow a schedule and a budget. The $30 billion in annual damage costs, the nearly 200,000 reported strikes, and the 29-to-1 hidden cost multiplier aren’t abstract industry problems. There are risks you manage on every project.
The PMs who treat utility coordination as a core project management function, not a utility company problem, deliver smoother projects with fewer surprises. They start early. They use the right tools. They build coordination into the schedule and budget from day one.
Next time you’re starting a project, make utility coordination part of your kickoff. Not the week before excavation. That’s the difference between taking a call about a struck gas line and never having to take that call at all.
