      Underground Survey & Utility Mapping

      Underground survey maps any assets and structures that occur beneath the ground surface; showcasing their position and depth, as well as any other potential hazards that may hinder a planned construction project on a site. Our surveyors and technicians utilise non-intrusive tools and equipment to collect accurate data that can help in feasibility, design and construction projects across Bolton and UK.

      Obtain utility maps displaying accurate positions of all subsurface utilities that may be encountered during ground breaking exercise. Our Bolton’s underground survey service will help you avoid digging into or damaging underground utilities that can possibly cause harm to the workforce and the public. Rely on our efficient underground surveying and lower project planning time, minimise risk, gain confidence ahead of excavation works, and avoid surprise utilities since our professional team adheres to health and safety regulations alongside the BSI standards – PAS 128 surveys.

      What we offer as part of Underground Survey

      Utility Survey and Utility Mapping

      Bolton Measured Survey provides utility mapping that offers reliable solutions for a wide range of clients. Our specialised underground survey services are tailored according to the industry specifications, such as PAS 128, providing cost-effective solutions in line with budget.

      Road Mapping

      Our road mapping services use drone technology to accurately inspect road projects, oil and gas pipelines, railway lines, transmission lines and linear right of way corridors. Road mapping survey is crucial for councils, transport agencies and civil engineering companies for the creation of accurate and precise large area linear maps and surveys of road reserves and existing road corridors.

      BIM Underground Services

      Bolton Measured Survey provides underground services data within a BIM environment, efficiently integrating building information, topographical information as well as underground utilities information in a comprehensive Revit model.

      CCTV Drainage Surveys

      At Bolton Measured Survey, we provide exceptionally accurate CCTV drain surveys as part of our specialised underground utility mapping. Through efficient CCTV surveys, any detailing defects, blockages, illegal connections and connections between access points, and the exact location of the drainage system between entry points and manholes can be determined.

      GPR Surveys

      Through non-intrusive scanning, GPR surveys provide an accurate underground imagery of your construction site. Our underground surveys combine GPR technology, total station and GPS devices to deliver efficient deliverables for clients across Bolton and UK.

      Concrete Scanning

      Bolton Measured Survey Company employs concrete scanning technology that uses cutting-edge ferro-scan, GPR scanning and ultrasound equipment to survey your structures, and reveal information on the underground elements, dimensions, and any anomalies. Our reliable concrete information will help inform your construction process, reduce stress among team members, eliminate downtime, and enhance productivity.

      CAD and BIM Modelling

      Bolton Measured Survey’s modelling specialists will conduct comprehensive scan coverage of your site and create a 3D point cloud using the latest software and customised automated extraction methods to retrieve the needed data.

      Site Investigations

      Site investigation process enables our specialist surveyors to collect information, assess data, and report potential hazards below a construction site.

      Geophysical Survey

      Our geophysical surveys use ground-based physical sensing techniques to produce a detailed map of an area. Bolton Measured Survey specialists depend on non-invasive methods for surveying culturally-sensitive sites. Ground-based geophysical surveys can take any of the following methods:

        • Ground-Penetrating Radar (GPR)

      A GPR directs an electromagnetic pulse into the ground. Reflections of the underground objects provide sufficient data from subsurface utilities; with travel time showing their underground depths.

        • Seismic Surveys

      Our survey team utilises geophones placed strategically to display rock properties several kilometres below the ground by creating vibrations using explosives.

        • Registered Earthworks Supervisor (RES) Scheme

      A GPR directs an electromagnetic pulse into the ground. Reflections of the underground objects provide sufficient data from subsurface utilities; with travel time showing their underground depths.

        • Electro-Magnetic Locator

      Our surveyors use advanced Leica DD series EML to survey an underground power cable.

      What Deliverables can you receive?

      Receive accurate utility mapping services and a wide range of detailed deliverables, such as:

      • 3D utility surveys data capture and modelling
      • 2D, 3D and 3D Modelled CAD
      • GIS Model
      • BIM Model

      What projects require underground survey?

      All construction projects, renovation works, addition, or modification works depends on underground survey as the first step. The utility lines, which normally cause construction obstructions, occur everywhere, even though they are not easily visible. They can be identified using utility location services and hence avoided.
