Measure, Verify, Map
Detailed Non-Invasive Underground Utility Surveys to accurately detect, trace & identify Underground Services across Construction & Development Sites.
At SurveyWorx we deliver Underground Service Mapping across both small & large-scale Private Development Schemes, Urban Regeneration Schemes, National Road Projects & major Construction & Engineering Works.
- Building Services Tracing & Mapping.
- Drainage Connectivity Surveys.
- Foul Drainage Route Surveys.
- Surface Water Route Surveys.
- Sub-Surface Void Detection.
- CCTV Condition Surveys.
- Desktop Record Searches.
Underground Utility Surveys can identify pipes, cables, ducts, sewers, gas pipes, foul drainage & surface water drainage routes across Construction/Engineering Projects.

Underground Utility Surveys
Underground Utility Mapping deliverables/outputs aid in the Planning & Design process for Architectural & Construction/Engineering purposes.
Our Team of experienced Geospatial Surveyors integrated with the latest technology & proven processes allow us to deliver an efficient & cost-effective solution to your Underground Utility Survey requirements.
Survey Methodology & Delivery
Underground Utility Surveys are carried out using a combination of Electromagnetic Location (EML) & Ground Penetrating Radar (GPR) Methods, with all Utilities physically Marked/Sprayed on the ground, with this information transferred onto a Topographical / Land Survey & delivered as a final Drawing in AutoCAD format.
Underground Utility Surveys would be related to the Ordnance Survey National Grid Reference System (OSGB36) & Ordnance Datum (AOD).
Survey Data is Post-Processed in-house through the use of dedicated Survey Mapping Software & rigorous QA/QC procedures to ensure we deliver consistent & reliable results, delivered in a variety of industry standard 2D & 3D formats.
Our experience combined with our commitment to new technology & innovations ensures we can efficiently & cost effectively deliver your Project to the highest possible quality standards.
CCTV Drainage Surveys
CCTV Drainage Surveys document the condition of Drainage Runs accessible within a Site. Surveys are delivered in the form of a Report documenting the type & position of any issues with the Drainage Runs, are accompanied with Photographic evidence, & delivered in WinCAN Format.
CCTV Condition Surveys can be completed for drainage networks, where manhole covers are lifted to identify & measure the content using a high definition Video Camera inserted into each pipe, noting defects, blockages & damage encountered.
BIM Underground Service Models
BIM Underground Service Models deliver Underground Services (UGS) information within the BIM environment, seamlessly integrating Topographical, Measured Building & Underground Utilities information in a comprehensive Revit Model.
Drainage Mapping Surveys
Drainage Mapping Surveys locate & map Drainage Runs (Foul Drainage & Surface Water Drainage) accessible within a Site. The Surveyed information is transferred onto a Topographical / Land Survey & delivered as a final Drawing in AutoCAD format.
Desktop Record Search
Desktop Record Searches provide statutory Record Drawings for a Survey Area. These include all Utility Companies’ owned infrastructure within the Site area presented in a pack & delivered in PDF format.

PAS128 Surveys
PAS128 Survey Type A – Verification
Utilities are Surveyed using direct measurement techniques at locations where utilities are exposed, at inspection chambers or by exposing Underground Services/Utilities using excavation techniques.
PAS128 Survey Type B – Detection (Most Popular)
Underground Services/Utilities are Detected, Traced & Mapped using one or more Geophysical Techniques.
PAS128 Survey Type C (Reconnaissance)
Site Reconnaissance Survey to validate available Underground Services/Utilities records & to assess if there are any conflicts that need to be investigated further or resolved.
PAS128 Survey Type D (Desktop Utility Records Search)
Underground Utility Service Records plotted to Drawing utilising Statutory Record Data which is gathered from Utility providers & owners.
Rebar / Concrete Tendon Scanning
We produce detailed Rebar Scanning Surveys to accurately detect & map Rebar & Concrete Tendon positions within Reinforced Concrete.
Rebar Scanning Surveys provide critical information to the Construction process allowing Project Managers & Design Teams to make informed decisions with respect to re-enforcement positions & depths across a Project.
- Reinforced Bars.
- Pre-Tensioned Tendons.
- Post-Tensioned Tendons.
- Metal Pipes.
- Fibre Cables.
Delivery/Output
- Technical Reporting.
- 2D & 3D AutoCAD DWG’s & PDF formats.
- Rebar Positioned Marked/Sprayed on Site.
