PAS:128 Surveys (Buried Utility Surveys)
3D Engineering Surveys employs Ground Penetrating Radar (GPR) and Electromagnetic detection (ELM) to conduct type B detection PAS:128 surveys across various industries. We specialize in Oil, Gas & Chemical, industrial facilities, electrical distribution and transmission, Highways, Water industry and Railway. We can support your needs throughout the project from conducting utility searches to final verification trenches. The surveys can be delivered to suit the customer's requirements in 2D or 3D CAD, or BIM.
Our site engineers can then survey, set out, and detect buried utilities during construction. Our trained and certified engineers can also form part of the permit-to-dig process to satisfy compliance when digging close to known utilities. Our industry experts mean that we can support your requirements in construction with a CSCS card holder supervised by SSSTS and SMSTS, in Oil and Gas with CCNSG, and on the Railway with PTS, COSS, and Track Handback Engineers available around the clock.

Deliverables and Services
Radio Detection Survey
Our services involve specialized equipment to locate and map underground utilities, such as metallic cables and other conductive objects. At 3D Engineering, we utilize the advanced Radio detection RD8000, a device capable of detecting objects at depths of up to 7-8 meters. The RD8000 offers a wide active frequency bandwidth range from 50Hz to 200kHz, allowing it to identify various types of buried utilities with high accuracy. Additionally, the device can store and review up to 1000 locate records, ensuring thorough and reliable documentation of survey results. This service is essential for construction, excavation, and maintenance projects to prevent damage to underground utilities and ensure safety.
Ground Penetrating Radar
Our Ground Penetrating Radar (GPR) service, utilizing the Opera Duo GPR with a dual-frequency antenna, employs electromagnetic radiation in the UHF/VHF frequencies. This technology is versatile and can survey various media such as rock, soil, ice, fresh water, pavements, and structures. It detects pipelines, void spaces, objects, material changes, and cracks. In dry, non-conductive conditions like those in Oman, it achieves optimal detection depths, potentially up to 5 meters. The IDS Opera Duo GPR utilizes a Grid Line Survey technique with an integrated GPS positioning system for precise data collection. Post-processing in GRED HD 3D CAD ensures efficient management of large datasets, with outputs compatible with CAD (AutoCAD or MicroStation) and GIS systems. Additional features include exporting GPR data and targets to CAD/GIS and generating synthetic maps. All radio detection data is meticulously marked in the field and integrated into 3D models, enhancing visualization alongside above-ground structures. This integrated approach has been successfully employed in notable projects like the Battersea Bridge Road survey for the 2012 London Olympics.
