When it comes to underground work, hydro excavation (also known as hydrovac) is often the safest and most precise method available. Whether it’s daylighting for engineering surveys or exposing utilities near live infrastructure, hydrovac trucks play a key role in telecom, electrical, and municipal projects. But there’s one piece of the operation that’s just as essential — and often underestimated: traffic control.
At Ikon Traffic, we know firsthand how traffic control planning and execution can make or break a job. Hydrovac work demands flexibility, precision, and safety — and so does managing vehicle and pedestrian flow around the work zone.
Why Traffic Control Matters for Hydrovac Jobs
Hydrovac operations, especially in urban or high-traffic environments, can’t proceed safely or legally without a solid Traffic Control Plan (TCP) in place. Depending on the scope and location, work might require:
-
Lane closures on arterial roads
-
Moving closures during long stretches of utility locating
- Multiple lane closure during work near intersections
-
Full shoulder closures for pot holing in tight right-of-way corridors
These closures must be coordinated with city, county, or state agencies — and must follow MUTCD and local guidelines. The right traffic control plan does more than protect your crew — it ensures the job stays compliant, avoids costly delays, and keeps the public safe.
Supporting Different Types of Colorado Hydrovac Operations
Hydrovac trucks and vac trailers support a range of telecom construction tasks, each with unique traffic control needs:
1. Pot Holing for Engineering and Plan & Profile Work
Early-stage projects often require daylighting to verify utility depth and alignment before design submissions. These jobs may span long corridors and involve frequent stops. Dynamic traffic control setups — such as rolling closures or multiple short-term TCP deployments — keep these jobs moving without disrupting entire corridors.
2. Sensitive Site Excavation
When working near critical infrastructure like ITS (Intelligent Transportation Systems), water mains, or energized electric, hydrovac is the go-to method. But these locations often sit on or adjacent to major roadways. Lane shifts, flagging operations, and extended shoulder closures are all common — and must be carefully designed to minimize exposure to live traffic.
3. Emergency Excavation Support
Fiber cuts, gas leaks, or electrical outages may require rapid-response hydrovac support — often outside of normal permitting windows. Working with a traffic control team that understands emergency protocols can make a huge difference in mobilization time and site readiness.
Building a TCP That Works for Hydrovac Crews
A well-designed traffic control plan supports not just safety — but efficiency. For hydrovac work, that means:
-
Placing cones and signage to allow for hose reach and boom swing
-
Accommodating multiple vehicles, including support pickups and vacuum trucks
-
Scheduling flaggers to allow for ongoing movement along a utility corridor
-
Maintaining line of sight and visibility around busy intersections or curves
- Planning for the potential of a rolling closure (including mobile arrow boards)
Partnering with traffic control professionals who understand construction phasing and utility excavation helps minimize rework, inspection issues, and down time.
Final Thoughts: Don’t Let Traffic Control Be an Afterthought
Hydrovac excavation may be the star of the show — but traffic control is the stage it performs on. Without proper planning, even the best crews can be sidelined by roadblocks (literally and figuratively).
