PAS128 Survey Company

At PAS 128 Survey Company, we provide professional underground utility detection and mapping services across the UK. Our specialist team focuses on delivering accurate subsurface data to support safe excavation, reduce project risk, and improve planning for complex developments.

By following the industry-standard PAS 128 framework, the PAS 128 survey company provides the technical clarity you need to meet health and safety obligations and prevent the catastrophic impact of utility strikes.

What Services Are Included When Working With a PAS 128 Survey Company?

Working with a PAS 128 survey company provides access to a comprehensive suite of data capture and verification tasks designed to ensure total site transparency:

• Utility Record Searches – Compiling and analysing historic drawings from statutory undertakers to provide an initial desk-based risk assessment.
• Site Reconnaissance – Evaluating the physical environment to identify surface features like manhole covers or service valves that indicate buried runs.
• Ground Penetrating Radar – Utilising non-invasive pulses to detect non-metallic assets such as plastic pipes and fibre optic conduits.
• Electromagnetic Locating – Tracing the route of conductive metallic pipes and power cables using radio-frequency signal induction.
• Post-Processing and CAD – Converting raw field observations into layered digital drawings that integrate seamlessly into your existing architectural plans.

Why Should You Choose a Professional PAS 128 Survey Company?

Opting for a professional PAS 128 survey company provides expert detection, accurate utility mapping, and dependable data that support safer project delivery. Professionals use regularly calibrated instrumentation that unvetted providers lack, which minimises the risk of striking high-pressure gas mains or primary electrical cables.

This expert oversight maximises site safety, providing a clear audit trail and protecting your investment from the financial fallout of accidental asset damage.

How Much Does a PAS 128 Survey Company Cost?

The cost for services from a PAS 128 survey company ranges from £850 to over £12,000 per site, depending on the acreage, the complexity of the utility network, and the specific Quality Level required.

Pricing is primarily influenced by the time required for on-site scanning and the density of the search grid needed for high-resolution results. Technical factors like soil conductivity for radar penetration, the requirement for traffic management, and the depth of data processing to create 3D Revit models contribute to the professional fee, ensuring the investigation remains technically sound for insurers.

When Should You Hire a PAS 128 Survey Company?

You should hire a PAS 128 survey company during the feasibility or pre-design phase of your project, ideally before any invasive ground investigation or excavation begins. Identifying buried hazards early allows for the safe relocation of structures or the careful planning of piling layouts to avoid critical mains pipes.

Engaging our team at this stage ensures that your groundwork strategy is factual, which prevents expensive project delays and provides the insurance-backed evidence required for high-value construction.

How Does the PAS 128 Survey Process Work With a Survey Company?

The operational workflow of our PAS 128 survey company involves a sequence of surface scanning, signal recording, and meticulous data analysis to guarantee technical integrity. Each stage of the process is designed to eliminate measurement errors through rigorous data triangulation.

Once the geomatic engineers capture the raw spatial points, the team converts these into high-resolution CAD drawings, providing the indisputable evidence required for engineering and legal assessments.

Where Are PAS 128 Survey Companies Required Across Projects?

Professional investigations by our PAS 128 survey company are required across a diverse range of sites, including active highways, rail corridors, and high-density urban construction plots. The service is critical for brownfield redevelopment and infrastructure schemes where records of buried assets are often missing or unreliable.

By mapping these environments, we protect your site teams from dangerous utility strikes, ensuring that your statutory safety targets are met while preserving the continuity of local services.

What Detection Methods and Survey Types Are Used by PAS 128 Survey Companies?

Our PAS 128 survey company utilises several advanced detection methods and survey classifications to provide the technical clarity required for safe digging:

• Ground Penetrating Radar (GPR) – Transmitting electromagnetic pulses to detect non-metallic utilities and subsurface structural features like voids.
• Electromagnetic Locators (EML) – Identifying conductive underground services by tracing magnetic fields generated by live power or induced signals.
• Vacuum Excavation – Utilising high-pressure air to safely expose utilities for the highest level of positional verification (Quality Level A).
• Precision GNSS Positioning – Recording the exact coordinates of every detected utility to align the survey data with the national grid.
• Quality Level Verification – Classifying survey results from QL-D through to QL-A to define the reliability and precision of each mapped asset.

What Standards and Compliance Requirements Apply to PAS 128 Survey Companies?

Strict adherence to British standards is what defines a professional PAS 128 survey company and ensures the technical reliability of our outputs. We follow the PAS 128:2014 specification for underground utility detection and mapping, alongside HSG47 guidance for safe digging.

Adhering to these UK standards ensures your results are legally defensible, providing the insurance-backed certainty required for safe working practices on high-value development sites.

Which Industries and Projects Require a PAS 128 Survey Company?

Diverse sectors rely on our PAS 128 survey company to manage the safety and financial risks of their physical developments:

• Civil Engineering Firms – Requiring precise utility mapping to design safe and compliant highways, bridges, and subterranean infrastructure.
• Property Development Groups – Using radar data to verify land suitability and avoid the high costs of unknown obstructions.
• Utility Providers – Needing accurate asset location to minimise service disruption during network maintenance or new connections.
• Local Government Authorities – Commissioning highway surveys to prevent accidents and manage the long-term integrity of public roads.
• Renewable Energy Contractors – Mapping cable routes for wind and solar farms to ensure efficient and safe grid connectivity.

How Quickly Can a PAS 128 Survey Company Complete Surveys?

Surveys from our PAS 128 survey company can typically be delivered within one to several days, depending on site size, complexity, and the required survey level.

Rapid data processing allows us to provide finished drawings shortly after the site visit is complete. This efficiency ensures that design programmes remain on schedule, providing your team with the high-resolution plans needed to advance the project without unnecessary delays or interruptions.
