Underground Utility

Surveys

Underground Utility Surveys detect and map hidden infrastructure like pipes and cables, ensuring safe excavation and accurate planning for construction and maintenance projects.

Comprehensive Surveys with GPR

At Alisteshaar, we offer accurate detection of underground utilities, including electricity cables, pipelines, and telecoms, using Ground Penetrating Radar (GPR) for enhanced safety and project efficiency. Our GPR surveys ensure precise identification of underground infrastructure to support safe and efficient project execution.

What is an underground utility survey and what do we do.

SHC 202 & SHC 203 guidance recommends that an underground utility survey is completed before working on or near to buried services.

Using the latest underground utility detection technologies, including Stream C, Radio Frequency Location (RFL), and Ground Penetrating Radar (GPR), we provide precise mapping and identification of all underground utilities. These include metallic pipes, plastic pipes, drainage systems, electric cables, communication lines, and fiber optic cables. Our technology enables comprehensive tracing of nearly any underground utilities. In Saudi Arabia, our underground utility detection surveys adhere to international standards such as ASTM D-6432 and are tailored to meet the Kingdom’s specific regulations and project requirements. Surveys are conducted to ensure compliance with local standards, including the Saudi Highway Code (SHC) and any applicable guidelines set forth by relevant Saudi authorities. Survey results are delivered in various formats to align with your project specifications, offering detailed and accurate utility mapping to support safe excavation and planning efforts. Other service levels and specifications can be provided upon request to suit specific demands.

Underground  utility survey

Real-time 3D mapping tool with 34 antennas in two polarizations to produce a real-time 3D reconstruction of the underground network in a single scan.

Stream C facilitates large surveys through its towing-kit, or smaller surveys due to its compact size. With automatic pipe detection, surveys only need to be performed in one direction which improves productivity and efficiency in underground utility detection.

Detects All buried services as shown in the image

  • Utilities/ oil /gas/water/
  • Metallic pipes/ high voltage compartment
  • Plastic pipes/ heat/telecommunication/
  • Drainage runs/sewer/drainage/
  • Electric cables, communication and fiber optic cables.

Radio Frequency Location (RFL)

Conventional technology behind utility detection surveys, and the tools used by SOCOTEC are the most advanced form of what most people know as “CAT & Genny” (Cable Avoidance Tool & Signal Generator).

Detects

  • Electricity cables
  • Communication cables
  • Telecommunication cables (metallic)
  • Metallic water, gas, fuel and vent pipes

Ground Penetration Radar

Used to locate buried objects which are foreign to the surrounding environment and can identify changes or interfaces between different media below ground. Although no indication is given as to the detected object’s material, and only general indications of size can be determined, this method is invaluable in obtaining information relating to the (previously invisible) underground environment. Detects Fiber optic cables
Plastic water, gas, cable, fuel and vent pipes, Concrete pipes
Clay pipes.

Acoustic Detection Systems

This tool is designed to detect and analyze sound vibrations, helping to locate pipeline leaks or identify non-metallic utilities. It works on the principle that leaks in pressurized systems, like water or gas pipelines, or the movement of liquids within buried utilities, create distinct sound patterns. These patterns can be picked up by sensitive equipment. Acoustic Detection Systems are portable, highly efficient, and equipped with advanced software to filter out noise, ensuring precise detection even in challenging environments.
