Underground Utility Surveys

Mitigate project delays and unforeseen costs with Underground Utility Surveys from Lucion’s Geospatial team. Safeguard your project, people, and the planet.

Underground Utility Surveys serve as your first line of defence, providing crucial insights into subsurface infrastructure. From gas pipes to drainage systems, our advanced technology, including ground-penetrating radar (GPR) and electromagnetic locators, ensures unparalleled accuracy.

We adhere to the PAS128 standard, ensuring reliable and consistent delivery of underground utility information. Compliant with British Standards Institution guidelines, PAS128 minimises dangers, conflicts, delays, and disruptions to your project.

PAS 128 Survey Category Type A

We confirm the presence and location of utilities through physical identification methods. Our Utility Clearance Surveys break ground and may include strategically positioned vacuum excavation, hand-dug trial pitting, or visual inspection within a utility chamber.

PAS 128 Survey Category Type B

An on-site utility mapping survey using multiple geophysical instruments. The results of this survey will represent each 5-meter linear section of utility, depicted with a Quality Level (QL) of 1-4 for horizontal and vertical detection accuracy.

PAS 128 Survey Category Type C

Underground utilities are mapped solely from utility record data, supplemented by site reconnaissance to align the utility records with the physical utility street furniture for the best fit.

PAS 128 Survey Category Type D

Our Desktop Utility Surveys involve a comprehensive desktop search of all statutory asset owners to obtain their record data. This is sometimes referred to as a C2 Search.

Before breaking ground, understanding what lies beneath is paramount. Accidental interference with water, power, gas, or sewage pipes can lead to costly setbacks, legal issues, and safety concerns.

Our utility surveys mitigate these risks, offering a comprehensive map of subsurface utilities, aiding in informed decision-making during planning and design. Uncover the invisible risks below for a safer and more efficient construction journey with Utility Surveys from Lucion, where precision meets safety.

Utility Surveys FAQs

PAS128, developed by the British Standards Institution (BSI) and the Institution of Civil Engineers (ICE), is the current standard for underground utility detection. It ensures the reliable and consistent sharing and delivery of all information related to underground utilities. With various detail categories available, PAS128 applies to engineers, construction businesses, project managers, utility owners, and surveying companies, setting out best practices for compliant underground utility surveys.

This highly accurate and detailed survey level is generally used in areas known to be densely populated with services, minimising danger, conflict, delays, and disruption to your project.

Construction projects, even when following protocols, can inadvertently damage underground utilities. The use of heavy machinery may lead to ground subsidence, affecting nearby pipes. Lucion mitigates these risks by offering services such as relining affected piping in a non-intrusive manner and ensuring the integrity of subsurface infrastructure during and after construction.

While our underground utility surveys provide information on the location of drainage pipes, CCTV drainage surveying offers insights into their condition.

By inserting a camera down piping, we can assess the state of the drainage system without the need for ground excavation. This preventative measure helps avoid potential damage during above-ground construction work.

Combining Cable Avoidance Tools (CAT) and Signal Generators, also known as Genny tools, with GPR ensures a comprehensive mapping approach. CAT locators focus on metallic objects, while Genny tools assist in tracing a range of utilities more quickly and precisely. This dual approach, coupled with GPR, allows us to map both metallic and non-metallic utilities efficiently.

Cable Avoidance Tools (CAT) trace signals emitted by metallic objects beneath the ground. While Ground Penetrating Radar (GPR) is effective for non-metallic utilities, CAT locators complement the process by precisely determining the locations and dimensions of metallic fuel, water, and gas pipes, enhancing the overall efficiency of our surveys.

Ground Penetrating Radar (GPR) emits pulses of energy into the ground, effectively revealing the locations of non-metallic objects such as plastic pipes and fibre optics with unparalleled speed and precision. This revolutionary technology enhances the accuracy of our mapping process, providing you with a detailed subsurface view.

An underground utility survey is a comprehensive mapping process that reveals the precise locations of subsurface utilities like pipes and cables. This information is crucial for project planning as it prevents accidental interference, avoiding costly setbacks, legal issues, and ensuring overall safety.
