Ground penetrating radar (GPR) technology was recently used by land surveyor Loy Surveys to undertake a complex utility mapping survey at one of the UK’s high security Ministry of Defence bases
Loy has recently invested in an IDS Detector Duo GPR device from Drilline Products. It uses radar technology to locate buried utilities and can identify power and fibre optic cables, as well as drainage and sewer pipes, irrespective of whether they are metallic or not. It is unique in that it uses two separate antennae for higher resolution and deeper investigation.
Operating within the confines of the strictest of safety zones, the team undertook a full underground service location survey to help the design team working on a project to repair and extend accommodation buildings.
Using an integrated approach, the surveyors conducted operations over an eight week period and were able to provide detailed information on service routes that would have on the proposed development.
“We have seen a significant uptake in demand for utility mapping surveys, as customers recognise the value in terms of safety and cost saving,” says Loy Surveys managing director Mark McGarragh.
“The investment in new technology allows us to offer a service that reduces the cost of conventional excavation, while at the same time delivering greater levels of accuracy. This minimises the risk of strikes and damage to underground utilities and reduces the design changes, which means fewer delays and penalties.”
“The innovative combination of advanced detection and mapping technologies is supported by a highly trained team of specialists who have the experience to understand our customers’ needs and ensure that they are fully met.”
Established in 1985, and with offices across the UK, Loy Surveys has undertaken over 10,000 surveys for a diverse customer base, which includes contractors, architects, engineers, local authorities, estate developers, oil companies and utilities.
In an industry where the penalties for damage to an underground utility are high, accuracy is the key to minimising risk and creating the safest possible environment on a construction project.
But technology is only as good as the person using it and Loy can draw on the company’s 30 year legacy of specialist training and development that has produced highly skilled surveyors.
It is a combination that has helped the business achieve a reputation for consistently high levels of service and customer satisfaction.
Loy’s surveyors are experts in the legislative and health and safety requirements that are crucial to any project and can evaluate all of the variants that may impact on a mapping survey, such as ground conditions, size and depth of objects and other external factors.
