How to Reduce Utility Strike Risk on Construction Projects

Intro:

Reducing Utility Strike Risk in Construction Projects

Large-scale construction projects come with a lot of moving parts — tight timelines, multiple crews, heavy equipment, and constantly changing site conditions. But one of the biggest risks on any jobsite isn’t always visible: what’s underground.

Utility strikes can lead to serious safety incidents, costly delays, damaged infrastructure, and even legal issues. The good news is that most of these risks are preventable with the right planning, coordination, and field practices.

Below are practical strategies to help reduce utility strike risk and keep your construction project moving safely and efficiently.

Start with Strong Pre-Construction Planning

The foundation of safe excavation starts long before equipment hits the ground.

Pre-construction planning is where most utility strike risks are either reduced - or unintentionally introduced.

At this stage, it’s critical to:

• Review all available utility records and drawings
• Identify known and potential conflicts
• Understand underground scope of work
• Coordinate with engineers and utility owners

However, utility maps are often incomplete or outdated. According to the Common Ground Alliance, many utility damages occur due to inaccurate or missing information.

That’s why planning should never rely on records alone.

Use Utility Locating, But Don’t Rely on It Alone

Calling 811 is essential, but it’s not always enough for large-scale or complex construction projects.

Public utility locating typically identifies:

• Major public utility lines
• Primary infrastructure

But it often misses:

• Private utilities
• Abandoned lines
• Undocumented installations

To reduce risk, many contractors use:

• Private utility locating services
• Subsurface Utility Engineering (SUE)

SUE provides a more accurate picture of underground conditions by combining records, surface scanning, and verification methods.

This is especially important in:

• Urban environments
• High-density utility areas
• Infrastructure-heavy projects

Verify Utilities with Potholing Before Excavation

Even with proper locating, verification is critical.

Potholing is one of the most effective ways to reduce utility strike risk. It allows crews to physically confirm the exact location and depth of underground utilities before excavation begins.

Benefits include:

• Accurate utility positioning
• Reduced guesswork
• Increased safety for crews

This step is essential when:

• Crossing existing utilities
• Working near critical infrastructure
• Beginning new trenching or drilling operations

Use the Right Excavation Method

Choosing the right excavation method plays a major role in reducing risk.

Traditional excavation methods are efficient but can increase the chance of utility damage in uncertain areas.

That’s why many contractors use hydrovac excavation when precision is required.

Hydrovac excavation:

• Uses pressurized water and vacuum systems
• Safely exposes underground utilities
• Minimizes damage risk

According to OSHA, using safer excavation practices and methods significantly reduces jobsite incidents.

Best practice:

• Use hydrovac excavation in high-risk areas
• Use mechanical excavation when conditions are confirmed and safe

Improve Jobsite Communication

Poor communication is a leading cause of utility strikes.

On large projects, multiple crews and contractors are often working simultaneously, increasing the chance of misalignment.

To reduce risk:

• Hold daily or weekly coordination meetings
• Conduct pre-task safety briefings
• Clearly mark and communicate utility locations

Everyone on-site should understand:

• Where utilities are located
• Which areas are high-risk
• What excavation method is being used

Keep Utility Markings Accurate

Utility markings can quickly become unreliable if not maintained.

They may:

• Fade over time
• Be disturbed by equipment
• Become outdated as the project evolves

To prevent issues:

• Re-mark utilities regularly
• Verify markings before excavation
• Never assume markings are still accurate

Coordinate Across All Teams

Lack of coordination between contractors and crews is a major risk factor.

For example:

• One team marks utilities
• Another team excavates later without full context

To avoid this:

• Share utility data across all teams
• Align schedules and responsibilities
• Maintain a clear communication system

Strong coordination ensures everyone is working from the same information.

Build a Safety-First Culture

Reducing utility strike risk isn’t just about processes - it’s about mindset.

Successful teams:

• Verify before digging
• Follow procedures consistently
• Speak up when something seems off

Creating a safety-focused culture means:

• Providing proper training
• Reinforcing expectations
• Prioritizing long-term outcomes over short-term speed

Be Prepared for Unknown Conditions

Even with proper planning, unexpected utilities or conditions can appear.

The key is knowing how to respond:

• Pause work when needed
• Reassess conditions
• Verify before continuing

A controlled approach prevents small issues from becoming major problems.
