Utility Surveys
Comprehensive Underground Utility Surveys for Safer Project Planning
Understanding the location and condition of underground utilities is essential before construction, excavation, redevelopment, and infrastructure works begin.
Our Utility Survey services provide detailed information about buried services, helping engineers, contractors, developers, and asset owners identify potential risks and plan works with greater confidence.
We use a combination of specialist surveying techniques, electromagnetic detection, GPR technology, site investigation, and existing utility records to build a clear picture of underground infrastructure.
What Is a Utility Survey?
A utility survey investigates and records underground services within a defined site or project area.
Depending on the project requirements, surveys can identify and map:
Electricity cables
Gas pipelines
Water mains
Telecommunications
Fibre-optic networks
Drainage and sewer systems
Ducts and conduits
Private utilities
Chambers and manholes
Other buried infrastructure
The information gathered can then be used to support design, excavation, construction, and infrastructure planning.
Our Utility Survey Services
Underground Utility Detection
We use specialist detection equipment to locate and trace underground services, helping establish their approximate position and route.
GPR Investigation
Ground Penetrating Radar can be used alongside other detection methods to investigate non-metallic utilities, ducts, voids, structures, and other subsurface features.
Utility Mapping
Detected services are surveyed and mapped to create a clear representation of underground infrastructure across the project area.
Utility Classification
Survey findings can be classified in accordance with recognised PAS 128 principles, providing structured information about the confidence and quality of utility data.
Topographical & Survey Data
Where required, underground utility information can be coordinated with surface survey information to provide a more complete understanding of the site.
CAD-Ready Deliverables
Survey information can be supplied in clear, structured formats suitable for use by engineers, designers, contractors, and project teams.
PAS 128 Utility Surveys
Our utility survey approach can align with the principles of PAS 128, the recognised UK specification for underground utility detection, verification, and location.
Depending on the project scope and investigation methods used, utility information may include classifications such as:
QL-C – Information based primarily on records and surface evidence
QL-B – Utilities detected using geophysical techniques
QL-A – Utilities verified through direct investigation
The appropriate survey approach depends on the project requirements, site conditions, access, and required level of confidence.
Why Carry Out a Utility Survey?
A detailed utility survey can help project teams:
Reduce the risk of damaging underground services
Improve excavation safety
Identify potential service conflicts
Support engineering and infrastructure design
Reduce unexpected construction delays
Improve project planning
Minimise unnecessary excavation
Understand existing site infrastructure
Support compliance and project documentation
Utility Surveys for Different Projects
Our surveys can support a wide range of projects, including:
Construction developments
Civil engineering works
Road and infrastructure projects
Commercial developments
Residential developments
Industrial sites
Utility projects
Property redevelopment
Highway works
Rail and transport infrastructure
From Survey to Clear Utility Information
Our aim is to turn complex underground information into clear, useful survey data that project teams can use during planning, design, and construction.
By combining multiple survey techniques and technologies, we help provide a more complete understanding of what is beneath the site.
Plan Your Utility Survey
Whether you are preparing for excavation, designing a new development, or investigating an existing site, an accurate utility survey can provide valuable information before work begins.
