How to Reduce Trenching and Excavation Safety Hazards

The work involved in exposing underground utilities can be intricate in nature. There is a lack of vision, due to the infrastructure being underneath the ground, meaning that accurately locating the target piping or cabling is difficult. This problem makes it incredibly important to gather as much intelligence as you can on the area in which you are working.

Finding underground schematics for the area is one of the first things that should be done when preparing to start work on a new site. The responsible contracting company that installed the infrastructure will have created detailing documentation for workers to use when performing repairs on the piping and cabling laid beneath the ground. You can use this information to speed along your utility potholing process. Read more about potholing construction.

Trenching for Repairs

Trenching is something that can be avoided by using vacuum excavation contractors. However, in some instances, it may be necessary to dig a trench to access the subsurface infrastructure. The proper definition of a trench, defined by the Occupational Safety & Health Administration, is a narrow excavation beneath the ground that is deeper than it is wide while being no wider than 15 feet.

It is crucial to have a competent person perform a survey of the area, aiming to find out the types of soil and rocks in the ground, as well as inspecting your protective systems and conducting regular site inspections. This person will be required by law to inspect trenches at the start of each shift, as well as following a rainstorm.

It is essential to decipher the type of ground materials you are working with, as this can affect the precautions you need to take before starting work. Some important factors that should be taken into account include the soil classification, water content of the soil, use of heavy digging equipment, depth of cut and other changes which can be caused by weather and climate. According to the Occupational Safety & Health Administration, or OSHA website, there is a range of safety precautions that need to be taken when trenching. The most common threat when trenching is the risk of collapse, which can result from the surrounding ground materials being too weak to hold up machinery and other items.

Generally, unless the excavation is performed in entirely solid rock, you will need to have a trench protection system in place. The first is called Sloping, which involves cutting the trench wall back at an inclined angle to ensure that debris does not fall into the trench. The second method is called Shoring and requires more work, such as the installation of support, items such as an aluminum hydraulic to prevent soil movement and cave-ins. The third and final method is Shielding, which protects workers by using trench boxes or other types of support that avoid soil cave-ins.

Overall, trenching and excavation are some of the most hazardous construction operations that you can undertake. This danger is why it is critical to take the necessary precautions to ensure the safety of workers on-site.

Expose Underground Utilities with Vacuum Excavation

Underground utilities are particularly susceptible to damage, especially when worked upon in more traditional ways such as manual digging and using a backhoe.

Manual Digging is the most labor-intensive method of exposing underground utilities, requiring significant worker numbers to accomplish the job. This kind of work can also take days to complete, requiring both the removal and replacement of soil, meaning that projects can fall behind schedule. Another significant risk encountered when manually digging is that hand tools can come into contact with electrical wiring beneath the surface, which can pose a significant threat to human life, causing either severe injury or even death. Due to these reasons, other modern methods have become more commonly used.

A backhoe requires the use of machinery in order to dig up the ground and expose buried underground utilities. This piece of machinery has a large bucket which digs into the ground, in much the same way as a hand shovel. Additionally, due to the larger size of these machines, this means that the job can be completed more quickly. The problem with this method, much like with hand digging, is the lack of vision that the machine operator has underground. This lack of visual information means that underground cabling can be damaged during the excavation process, incurring significant costs and project delays while repairs are made to the existing infrastructure.

These older methods of potholing utilities have been replaced by a quicker, more cost-effective method called Vacuum Excavation.

What is Vacuum Excavation?

As the name suggests, vacuum excavation involves the removal of ground materials through suction. This method of excavation can be done in two different ways.

The first type of vacuum excavator uses water; highly-pressurized water is used to dislodge and remove soil. A vacuum is then applied over the area to suck up and store debris. Water excavation can be useful in situations where the ground would otherwise be too hard to simply vacuum. The high-pressure water helps to increase the moisture of the soil and make it easier to break up. Water vacuum excavation is suitable as it is non-destructive and allows for more accurate excavation of underground utilities.

The second method is simply air vacuum excavation. This method is suited to areas with loose soil and ground materials, which are quickly drawn up through an intake nozzle into a dry debris container. From here, you can unearth the underground utilities that you need to work on without causing any damage, similarly to the water excavation process. Once the work has been completed, a driver will dump the dry soil back into the hole you’ve created.

Overall, both of these methods are hugely useful at increasing safety on the worksite. Hand Digging is labor and time intensive, but it is also dangerous as workers can come into contact with live electrical wiring. The same can occur when using a backhoe. This danger is why you will now commonly find a Vacuum Excavator being used to expose underground utilities.

Potholing Utilities for a Cost Efficient and Safer Excavation

Potholing for utilities is a method that construction site workers can use to obtain a wealth of visual information regarding piping and other subsurface construction. Utility potholing has increasing importance in the construction industry, as a method that can help to make excavation safer and more cost-effective to do.

In the past, it was commonplace for contractors to use a backhoe. This piece of equipment is highly recognizable to the general population as a typical piece of machinery you would find on a construction site. However, it does not have the precision or maneuverability of more modern excavation machinery, meaning it has the potential to cause immense damage to existing subsurface infrastructure.

Vacuum excavation is a process in which water is pushed through the earth creating a hole that allows the crew to visually confirm the location of the utility lines. As the earth is removed to create the hole, it goes into a special storage truck that can easily be removed from the construction site and dumped elsewhere.

Not only is potholing the most accurate way of learning the location of utility lines, but it is also time and cost-efficient. Keep reading to find out the many other benefits of using vacuum excavation on your construction site. Know more about pothole utilities.

Increased Safety using Vacuum Excavation

Nowadays, you are much more likely to find a vacuum excavator being used. These highly portable pieces of machinery use air to displace soil. Since the air and water are only vacuuming at low pressures, this means that other utilities in the ground will not be damaged, which makes vacuum excavation the preferred method compared to using a backhoe.

While vacuum excavation is an extremely safe process, there are still a number of precautions that should be taken to keep your crew and members of the public safe. Before utility potholing can take place, you should reach out to third parties who have knowledge of the construction site. They might be able to provide you with recent utility line maps or estimations for how deep the holes will need to be.

It is also always recommended that you hire an experienced team that specializes in vacuum excavation They will have the training and expertise necessary to do the job safely and efficiently. A professional team will also understand the importance of preliminary work such as using RADAR or digital technology to gather estimates for locations and depths.

By hiring specialists, you will minimize the risk of damage to the utility lines as well as the expensive excavation equipment. You will also save money by avoiding the possibility of a utility strike which can cause expensive repairs or fines if it affects the local community.

Vacuum excavation also has a wealth of other benefits compared to using a backhoe. When excavating, a backhoe will displace a considerably larger amount of soil compared to a vacuum excavator. A vacuum excavator simply stores the displaced soil inside the machinery, meaning there is no need for a dumping ground.

Increased cost efficiency using Vacuum Excavation

The next important benefit of using vacuum excavation, compared to backhoeing and manual labor, is the reduction in costs.

Manual digging is an outdated method of excavating that requires a significant number of man-hours to accomplish the same thing as backhoeing and vacuum excavation. In comparison, vacuum excavation would be much quicker while also causing much less disruption to the ground. Once work is complete, workmen would also have to refill the holes they had made, doubling the time taken.

Considering the amount of manpower required to excavate utility lines as well as the extended time frame to get the work done, relying on hand tools is a very costly option in the long run.

The cost implications for backhoeing are different from manual labor. This piece of machinery can be a great tool when displacing ground is clear of subsurface infrastructure. It can accomplish what multiple workmen would do in hours, in mere minutes. When used in an area containing subsurface infrastructure, the damage that can be caused by the metal bucket on a backhoe hitting existing piping and cabling could be disastrous. This would most likely result in the project being put on hold, whilst repairs to the infrastructure are completed by those who caused the damage. As you can see, the risks of using a backhoe are very real, meaning it is a good idea to consider using a vacuum excavator instead when potholing utilities. Know more potholing companies.

Summary

In summary, vacuum excavation is a new and improved method of potholing utilities.

A professional excavation team will understand the needs of your construction project and will also work diligently and efficiently. This means your crew and the land itself are kept protected throughout the excavation process.

The use of low-pressure water and air by this system means that existing subsurface infrastructure is less likely to get damaged, versus other methods such as backhoeing and manual digging. The cost savings and improvement to site safety can also be immense through this mitigation of risk.

Avoid Excavation Hazards and Utility Strikes, Call the Potholing Experts

It is well known that construction sites are inherently dangerous and there are a lot of risks that go along with excavating earth. Although it is tempting to choose the cheapest or least time-consuming option to get the job done, such choices can lead to expensive disasters down the line. Utility potholing uses vacuum excavation technology in order to carefully and efficiently locate all underground utility lines without damaging them.

Utility potholing is an excellent option for most construction projects and will likely save you and your crew both time and money. Using a professional team will ensure that your construction site is excavated properly and as quickly as possible. While potholing is an investment, it will ensure that you avoid extensive damage and expensive repairs or fines.

Keep reading to learn how vacuum excavation can help your construction project run smoothly without the risk of utility strikes.

Other Tools Don’t Cut It

When you compare potholing to the other tools available, it becomes quickly obvious that professional potholing is the best choice.

Those with smaller construction sites often think that excavating the land by hand is the best option because it is so inexpensive. However, digging with hand tools like shovels and trowels requires grueling physical labor. Depending on the site, it can also take many days to complete. The contractor might want the work completed by a certain deadline and it just isn’t possible to know exactly how long excavating by hand will take.

While hand tools might not cause damage to utility lines, it isn’t recommended that you use this time-intensive and exhausting method.

Meanwhile, you might also consider renting a backhoe because they are generally considered an affordable and efficient method. However, it is incredibly difficult to use finesse with a backhoe, which means there is a much greater chance of striking a utility line. This is a fine option if you are certain there are no live utility lines under the land but should be avoided otherwise.

If you do opt for a backhoe, remember to employ an experienced spotter who will help guide the equipment and avoid utility lines. Even so, the risk to utility lines is far greater than it would be with vacuum excavation.

How Potholing Works

Potholing works to carefully excavate a construction site through the use of air or water pressure.

Air or water is gently, but firmly, push through the earth so that the locations of utility lines can be discovered without physically touching them. Even better, the use of an air jet allows the earth to be stored and reused at a later time in the construction process. While this cannot be done with a hydro jet, both are great options for keeping your construction site safe.

Potholing is an effective method that involves clearing the earth away from utility lines. It is also time-efficient and cost-effective. When used properly, vacuum excavation is the best method available for any construction project.

Safety Precautions

As with any construction equipment or machinery, safety measures must be taken to ensure the well-being of your crew.

You will still need to plan ahead of time to fully understand how to vacuum excavate the property. For instance, you should call all relevant third parties who have knowledge of the construction site. These third parties may have information concerning utility lines, which will assist you during the excavation.

It is always safer to choose a professional, experienced team. These professionals understand the delicate excavation process and will be much faster and more skilled than an untrained worker.

A professional team will also understand the importance of inspecting the area beforehand. This involves creating a small hole through which the professional can explore the underground area. RADAR or digital technology doesn’t compare to visual verification of what is underground. Damage to underground utilities can result in unexpected expenses from repairs or fines.

Usually, these fines occur if the damage disrupts access to utilities for those living and working in the surrounding area. It is important to respect the local community and do everything possible to ensure the construction is safe and takes necessary precautions.

When in Doubt, Seek Help

If you are in doubt about how to excavate your construction site, it is advised that you choose potholing. Vacuum excavation is an advanced technique that, when carried out by an expert, is both safe and efficient.

By opting for potholing, you avoid the risk of striking a utility line, which could severely impact the overall success of the construction project.

Not only will a professional team be able to understand the needs of your project, but they will carry out the work without putting workers’ health and well-being at risk, as well as protecting the land itself. See private utility locating companies near me.
