It’s important to locate the position of underground services and pipes before any excavation work begins, service outages and severed pipes can lead to disaster. Undertaking an underground services report gives you vital information required to prevent such problems. All services located and mapping accurately plotted onto a CAD drawing using Leica Total stations and can be delivered in a variety of file formats. CCTV Drainage Surveys London.

A Utility Mapping Survey is a type of drainage survey conducted to accurately locate and map underground utilities and infrastructure. The goal is to identify the location, depth, and type of buried utilities such as water pipes, gas lines, electrical cables, telecommunication cables, and sewer systems. This information is crucial for construction projects, infrastructure maintenance, and urban planning from Hampshire to London to avoid damage to existing utilities during excavation and construction activities.
The Utility Mapping Survey typically involves the following steps:
Initial Planning: Before conducting the survey, the surveying team reviews existing utility records and as-built drawings, if available. This information provides a starting point and helps in planning the survey approach.
Ground-Penetrating Radar (GPR) Survey: Ground-Penetrating Radar (GPR) is a commonly used method in utility mapping surveys. GPR uses electromagnetic waves to detect variations in subsurface materials, allowing it to identify buried utilities. GPR data is collected by scanning the area with specialized GPR equipment.
Electromagnetic Induction (EM) Survey: In addition to GPR, electromagnetic induction techniques may be used to detect metallic utilities like buried pipes and cables. EM instruments can detect conductive materials and provide valuable supplementary information to GPR data.
Utility Verification and Marking: Once potential utilities are detected using GPR and EM surveys, the surveying team verifies their presence through manual techniques such as digging test pits or using utility locator devices. Markers or flags are placed on the ground to indicate the location of identified utilities.
Data Processing and Integration: The collected GPR, EM, and manual verification data are processed and integrated to create a comprehensive utility map. This map will indicate the positions of utilities, their depths, and any potential conflicts with proposed construction or excavation plans.
Utility Mapping Report: A detailed report is prepared, presenting the findings of the utility mapping survey. This report includes the location and depth information of identified utilities, along with any recommendations or precautions for construction activities in the surrounding areas of Sussex, Surrey, and beyond.
