How to prepare a site for hydro excavation? When planning
In the concealed depths beneath our cities and countrysides, a complex network of underground utilities powers our daily lives. These essential services—water, gas, electricity, and telecommunications—are the lifelines of modern society. Yet, their hidden nature poses significant challenges during construction and excavation projects. Understanding the significance of protecting these underground assets is the first step towards mitigating potential risks and ensuring the seamless progress of construction endeavors.
The need for comprehensive underground utility protection goes beyond avoiding safety risks; it directly influences the cost-effectiveness and efficiency of construction projects. The Common Ground Alliance (CGA) in its 2019 Damage Information Reporting Tool (DIRT) Report, unveiled an alarming 532,000 instances of excavation damage, translating into a staggering $30 billion cost. This rising trend highlights an urgent need for improved detection and excavation methods.
Traditional detection methods, such as electromagnetic locators, offer a partial solution by identifying metallic components of utilities. However, their effectiveness is limited by the inability to detect non-metallic utilities and susceptibility to external electromagnetic interference. To supplement these methods, potholing or daylighting has become a widely adopted practice. This is a technique which involves digging small test holes to visually inspect and verify the utilities.
Advances in technology, such as Ground-Penetrating Radar (GPR) and Augmented Reality (AR), have significantly enhanced the accuracy of underground utility detection. These tools allow for non-invasive scanning of the subsurface, providing detailed images of buried utilities regardless of their material composition. Despite their benefits, these technologies also face limitations, influenced by soil conditions and the cluttered subsurface environment.
Amidst these challenges, hydrovac excavation stands out as a highly effective method for safely locating and excavating around underground utilities. Unlike traditional methods, hydrovac uses high-pressure water to safely expose underground utilities, allowing for direct visual verification. This process, known as potholing or daylighting, is not only safer but also significantly more precise than conventional excavation techniques.
It’s important to remember that safe digging practices, including calling 811 or the local One-Call center before any excavation, are crucial steps in preventing utility damage. This applies to projects of all scales, from simple backyard undertakings to large-scale professional excavations. Failing to follow these protocols not only poses a risk to underground utilities but also threatens the overall safety and success of construction projects.
The importance of meticulous underground utility protection cannot be overstated, and with the hydrovac solutions provided by Emeritec Hydro Vac, the industry has a powerful tool at its disposal.
