Why Potholing is Highly Recommended for Construction Projects

Potholing Job Completion

Construction contractors can use potholing to safely control potential problems while searching for underground utility main lines, such as for natural gas or cable television, without causing a severe inconvenience in the local area. The loose soil from the test hole can be quickly and easily removed with vacuum excavation to then provide an open space for construction workers to use to inspect for underground utility main lines. With practical techniques for reducing the number of potential problems, a construction contractor can control the costs and can focus on the construction schedule.

Utility potholing locates utility lines by using forceful water pressure to push through the earth, creating a small home in the process. When the hole is deep enough, your construction crew will be able to visually confirm the location of any underground utility lines. This will allow your other construction work to resume without risk of interfering with any existing lines.

Potential Problems for Construction Contractors

The location of some underground utility main lines may not be documented because those lines for fiber optics or wastewater may not have been used by the current owner of a building that had been demolished for a new project such as for new art and entertainment center. The contractor can use potholing in construction projects to prevent problems and to protect the workers who could be injured by an underground hazard.

Evaluation of Potential Costs

The process for being offered a construction project usually includes bids from several contractors who must submit a construction plan and a budget for the project. Some of those contractors could encounter budget problems, such as for additional labor, equipment and supplies expenses while being forced to replace an underground utility line that had been accidentally damaged while trying to build an underground garage for a new apartment building. Managers can use potholing in construction projects to protect investments and to become more prepared for accurately planning a new project.

With the risk of utility line damage and service interruptions, comes expensive and time-consuming delays that might have to be approved by a local planning permission authority. Time is an expensive commodity on any construction site, which makes these delays and extra expenses something you don’t want to risk. Bypass these dangers by hiring an experienced potholing team. Not only will this keep your construction project running on time, but you will also be keeping the crew and nearby residents protected from utility outages.

Easy Access to Construction Sites in Isolated Locations

Some heavy construction equipment could be unsafe in an isolated area where a hidden water well or a concealed sinkhole had not been filled with soil to control the problem. With vacuum excavation, a contractor can use equipment that will cause fewer safety problems and that can be used to easily remove soil without blocking a path with a pile of soil while digging to search for underground utility lines.

Protection for Workers and the Environment

The aesthetic advantage of underground utility lines is a problem for contractors who want to quickly locate those underground utility lines. The techniques for utility potholing can be used to minimize the degree of damage to the topsoil at a construction site. With more detailed information about underground utility lines, a contractor can move forward with a project while also protecting the environment and not endangering a worker.

Plans for Controlling a Potential Problem

Vacuum excavation will prevent damage to utility lines, flooding, and service outages. Additionally, construction crews cannot dig in ‘safe zones’, which is the land that runs parallel alongside the utility lines.

In conjunction with utility potholing, you can first find the approximate location of unground utility lines and other facilities by using digital equipment and ground-penetrating RADAR. However, nothing can replace the certainty that comes with vacuum excavation and visual confirmation of the utility lines.

The various factors for improving the quality of a construction project can be controlled with different methods such as with more safety equipment and with innovative techniques. A contractor can use utility potholing to reduce the worker turnover rate with safer working conditions and to ensure that the project will be a success. Project managers can conveniently contact Util-Locate for professional advice about the potholing services for a construction site.

Why Utility Potholing Is Essential for A Successful Construction Project

It’s long been said that if humans could see all that is under the ocean, they’d never leave the shore. The same is true of nearly any developed property, whether you are starting a new structure, repairing a building or adding to an existing site. You’re going to want to look into a process called “utility potholing.”

Potholing is a construction method where a small hole is placed in the ground through a process called vacuum excavation. Once the hole is deep enough, it is possible for a construction or inspection crew to confirm the presence of utility lines visually, and water or sewer pipes. Once located, the crew will be in a position to make certain the existing lines won’t conflict with either above or below-ground construction plans.

The equipment used to create the excavations through the potholing process are self-contained units designed to avoid damaging underground infrastructure. Here’s why utility potholing is essential for a successful construction project.

Safe Zones

To avoid the possibility of damage to lines and subsequent site damage, flooding or service outages in the surrounding community, construction crews are not permitted to dig in safe zones, which are the areas within a few feet of either side of any previously located utility line.

Though it is possible to approximate the location of utilities and underground facilities using digital equipment and ground-penetrating RADAR, it is far more precise and far less risky if the construction crew can visually ascertain the location and alignment of any lines that might pose a hazard to the construction project.

Scheduling and Costs

Leaving aside the potential of damage and service interruptions in the event a dig might sever an underground line, the resulting delays and potential sanctions experienced by a contractor or construction crew can be both costly and harmful to the construction crew itself. Time is money, and many construction projects are operating on thin margins in the best of circumstances. The minimal time savings of bypassing prudent potholing isn’t comparable to the practically unlimited liability issues involved in damaging a public utility.  It’s always better to be on the safe side if only to protect the other residents in the neighborhood.  

Physics

What if it were possible to simply vacuum soil out of the ground at a precise location? If no tools are penetrating the ground, they can’t damage anything built underground either. If a vacuum can store the removed soil, it can also replace that soil, meaning there is no lasting effect on the site. The vacuum excavation process, therefore, delivers a non-destructive way to inspect the subterranean environment without any of the above-noted risks.  

If a process is safer, less expensive, leaves no permanent evidence it was ever performed, and can obtain better and more accurate information about ways to avoid damaging a site or public property, it stands to reason it is something that should be considered any time there is a potential for the presence of utility lines at a construction site.

How the Murrieta Explosion Could Have Been Avoided

murrieta explosion

 

Southern California was recently devastated when a ruptured gas line led to an explosion. The explosion killed a Southern California Gas Company worker, and fifteen people were injured.

Murrieta Explosion The reason behind the Murietta explosion was a contractor who was working without having the area inspected first. The contractor not only caused irreversible damage but violated state law by not utilizing a  private utility locating service. Tragedies like this can be avoided when proper utility potholing and inspections are used.

 

What is Utility Potholing?

Potholing is a construction method that confirms underground utilities and obstructions. Utility locating is the first part of the investigation process. A small, exploratory hole is dug along the planned route of new construction. Air and hydro vacuums are used to remove soil via high-velocity suction.

Some contractors like to use digital locators to find pipes and other utility lines. There are many occasions, however, where it is essential to actually see where the wire or pipe is located.

Why Pothole?

Murrieta Explosion

Digging without first locating underground utilities creates a risk to gas, electric, communications, water, and sewer lines. Accidents with these lines can result in service disruption, costly repairs, serious injuries, or death. While it may mean delaying a project, knowing where lines are before you dig ultimately makes sure projects are entirely safe.

 

Why vacuum excavation?

In the past, potholes were dug with large machines, like backhoes. Unfortunately, even a skilled backhoe user runs the risk of damaging the very utility they wanted to protect. Some companies resort to digging by hand. While this method required less machinery and skill, it is somewhat labor-intensive. A shovel is unlikely to cause damage to a water pipe, but could completely sever fiber optics or other communication lines.

The current preferred method of potholing is vacuum excavation. Vacuum excavation happens after utility locating and verifies the utilities by exposing them for visual identification. This method allows for small holes to be created with a much lower risk of additional damage. Vacuums also can create holes of different sizes and depths without extra manual labor.

Plan before you dig!

Whether you are doing the work yourself or hiring a contractor to take over, you must plan appropriately. Even smaller projects, such as planting trees or shrubs, require knowing what’s beneath the ground. Many utilities are only buried a few inches below ground, which makes them easier to hit when performing simple gardening projects.

Make sure to call several days before you plan on putting a shovel to the ground. Be careful as some programs only mark the area where utility lines are placed. You may also have to wait for multiple companies to take care of marking the area. Also, be aware that utility companies may not go onto private property. For a better response and completion time, consider going with a private utility locator company.

While some accidents are avoidable, many accidents don’t need to happen. Murrieta Explosion The explosion in Murrieta destroyed more than a house; it took a person’s life. Contractors might think they know better, that they are skilled enough to work around utilities, or they want to save time on a project. However, taking the extra time to identify underground obstructions is the best way to ensure your project is completed without tragedy.

How to Prevent Damage to Underground Utilities

Utility Making Surveys

For any successful project, utility locating is very essential to avoid costly damages or accidents resulting from digging or excavation. Without proper locating, problems can arise that can be very hard to circumvent. This is why you need a reliable locating service regardless of how small the project is. You cannot rely on line of sight of utility trails. Looking for top-notch utility locating services will ensure that you don’t incidentally come into contact with underground infrastructure. Here are three things you should know about utility locating.

Utility Locating is a damage prevention control prior to excavating/digging.

There are many dangers that exist when you try to dig without proper locating. Underground gas lines pose a safety risk if they are interfered with. Fiber optic lines, water lines, power lines, sewer lines, and other utility lines are very expensive to replace or repair. You don’t want to run into buried lines when digging and cause a major inconvenience. Here at Util-Locate, we give you the confidence to dig knowing that you are safe.

This can lead to injury and loss of many lives, and cause property destruction worth a lot more money. Our highly trained utility locators are not only focused on damage prevention but also in ensuring no life is lost because of an avoidable mistake.

A single call can save you thousands of dollars and prevent disaster from occurring. We use state-of-the-art technology to improve accuracy and give you peace of mind for all your excavation and digging projects.

3 Underground Utility Locating Equipment You Should Know

3 Underground Utility Locating Equipment You Should Know

Utility locating not only requires years of experience, but you also need the right tools or equipment to do it successfully. This is true whether you’re a beginner or a veteran searching for utility locations before you dig.

While you’ll probably hire professional utility locators to unearth buried utilities for you, it’s still worth learning about the tools they commonly use to detect utility lines. That’s why we’ve broken down the three basic types of utility locating equipment below!

To truly understand what happens during utility location, take the time to read about magnetic locators, pipe locators, and cable locators that utility companies use.

1. Magnetic Locators

Locating a single point, such as a rebar corner pin or a water pipe, is the primary function of a magnetic locator. Its name refers to its ability to detect objects in underground facilities that would attract magnets.

A magnetic locator is sensitive enough to find even a single ferrous object like steel property pins, manhole lids, and water or gas valves. However, magnetic locators are not recommended for locating underground utilities; rather, a pipe and cable locator should be used for this purpose.

2. Pipe Locators

During utility location, detecting buried pipelines can be a real headache when you don’t have a pipe locator. This nifty tool locates pipes by emitting an electromagnetic frequency that travels through the earth.

That frequency would then ricochet off of any pipelines or similar materials that might be buried underneath. The device is usually attached to the main water valve or hydrant and is used to trace water lines before digging or excavation begins.

3. Cable Locators

Similar to a pipe locator in terms of function, a cable locator is a utility device used to pinpoint the exact location of underground cables or signal lines before you dig.

To estimate the location of subsurface lines and cables, the device also emits electromagnetic frequencies. Most cable locators can be utilized for both direct-connect or inductive-coupling approaches.
