What are the key benefits of Underground Surveys?

What is an Underground Survey?

An Underground Survey refers to applying geophysical techniques to explore and create a digital representation of the underground and what is buried there that may have significant impacts. The survey involves using the latest laser scanning technology and equipment to conduct, including Electromagnetic Locators (EML) and Ground Penetrating Radar (GPR), to explore what is buried underground. It thus aids in project planning by enabling understanding of the layers, structures and objects beneath the ground.

Need for Underground Survey

Before breaking the ground, it is necessary to understand the structure, layers, objects and utilities that may be present beneath the ground. There have been reports of utility strikes in the past, killing builders and affecting the public. They also result to cost and time implications on the projects. It thus requires a cost-effective solution to understand the nature of the ground and the objects present beneath to avoid unexpected occurrences. An underground survey is a cost-effective and reliable approach that can significantly help equip builders and project managers with the knowledge they need before breaking the ground.

Benefits of the Underground Survey

The underground survey is crucial as it shows the accurate position of objects and utilities buried in the ground where the proposed project should occur. It thus helps avoid digging into utilities that may harm the workers and the public. The specific benefits include:

  • Useful in the design and planning stage. The underground survey ensures the project manager and the builders have full knowledge of the utilities beneath the ground. Therefore, the design is only done once without the need for adjustments due to unforeseen utilities in the underground. It also optimizes the connection of new site supplies based on the existing utilities and indicates any possibility of utility diversions in the planning process. It thus mitigates potential challenges related to various utilities on the ground, such as electrical connections and industrial components.
  • The 2D CAD drawings and representation of the objects and utilities in the ground are produced digitally. Thus, it facilitates faster and more accurate access to the relevant data on the underground structures and components and leads to highly reliable and highly accurate results
  • Health and safety issues. It minimizes the overall risks since the builders already know where various utilities and objects are located underground. It assures health and increases safety of workers and the public. Health and safety are important considerations before beginning any excavation process. Therefore, by guaranteeing health and safety, underground surveys help address the project’s crucial aspects regarding the well-being of the builders and the general public in the surrounding environment.
  • Help avoid surprises and improve on cost and time. The worst occurrences while undertaking a project are surprises. They can be costly and time-consuming. Imagine starting the excavation only to realize that the properties and objects underground cannot allow the project to continue. More processes have to be considered and implemented to make the project possible or abandon the project entirely. It would be the worst surprise. That’s why underground survey is such important during project planning.
  • Makes invasive underground inspection unnecessary. Many projects spend a lot of time and resources during planning for invasive inspections, which, compared to underground surveys, produce limited information. Conducting underground survey, instead, saves on time and expenses that would have been incurred in the process.
  • Enhances the confidence of the builders and project managers before excavation begins, which makes the excavation process moves faster and avoids delays. Without awareness of what is beneath the ground, builders and project managers would tend to be more careful during excavation, which would make the process go slowly and may cause project delays.
  • Complying with BSI standard PAS 128 Surveys. The underground utility surveys provide a representation of the underground, indicating the utilities and objects present. It thus provides a clear indicator of conformity with the PAS 128 standards required in the UK before breaking the ground in infrastructural projects.
