At PAS128 Surveys in Swanscombe, we deliver fully compliant underground utility mapping services to the latest PAS128 standard. 

Our surveys help reduce ground risk, improve safety, and support better design decisions by providing accurate data on buried services before excavation or construction begins.

Whether you’re planning a residential scheme, commercial development, or infrastructure upgrade in Swanscombe and across the UK, our team ensures that you know exactly what’s beneath your site—before you break ground.

Why Is PAS128 Survey Important For Projects In Swanscombe?

For projects in Swanscombe, PAS128 surveys are critical because they reduce the risk of utility strikes, project delays, and costly rework. They also support health and safety compliance under CDM regulations.

Whether you’re in the early planning stages or about to begin excavation, a PAS128 survey gives your team confidence in what lies underground.

What Are The Different Survey Types Defined Under PAS128 In The Swanscombe Region?

We provide all PAS128 survey types in Swanscombe, each designed to meet specific project requirements and levels of data certainty, including:

• Type D (Desktop utility records search) – Review of existing utility plans, drawings, and statutory records to understand likely underground service locations.
• Type C (Site reconnaissance) – On-site inspection to compare records with visible surface features such as manholes, valves, and utility markers.
• Type B (Detection survey) – Use of technologies like Ground Penetrating Radar (GPR) and Electromagnetic Locators (EML) to accurately detect underground services.
• Type A (Verification survey) – Physical validation of utility positions through safe excavation, often using vacuum excavation for precision and minimal disruption.

How Much Do PAS128 Utility Surveys Typically Cost Near Swanscombe?

The cost of PAS128 utility surveys in Kent ranges from £600 to over £5,000, depending on the size of the site, complexity of buried services, and the level of detail required.

Prices are influenced by factors such as survey type (e.g., Type B detection or Type A verification), use of technologies like GPR and EML, the need for CAD or BIM deliverables, and whether out-of-hours access or emergency callouts are needed.

Which Projects Around Swanscombe Require PAS128-Compliant Utility Mapping?

PAS128-compliant utility surveys are widely used across infrastructure, construction, and design-led projects in Swanscombe.

These include roadworks, public realm improvements, utility installations, drainage upgrades, new housing developments, and commercial construction schemes.

Any project involving excavation or subsurface design benefits from knowing the precise location and type of buried utilities on-site.

In some cases, local councils, utility providers, or principal contractors may require PAS128 data before issuing permits or allowing works to proceed.

What Deliverables Are Included In A PAS128 Survey Package Across Swanscombe?

Our standard PAS128 survey package in Swanscombe includes a full range of clear and actionable outputs, including:

• Utility drawings (CAD format) – Detailed layouts showing the location, type, and quality level of all detected underground services.
• PDF, GIS, or BIM-compatible outputs – Optional formats are available to suit your design, engineering, or asset management needs.
• Formal written report – Includes survey methodology, site observations, data classifications, and any site-specific limitations.
• Metadata logs – Full records of survey settings, detection methods, and data capture details.
• Photographic records – Visual documentation of key findings, site conditions, or surface evidence.
• Recommendations for further action – Expert guidance on any follow-up surveys, verifications, or risk mitigations needed.

What’s The Difference Between A PAS128 Survey And A Basic Utility Scan?

For construction sites PAS128 surveys have multiple levels of data quality, survey techniques, and documentation standards, while a basic scan may involve a single method of detection, such as EML, and minimal reporting.

PAS128 requires trained surveyors to follow a documented process, classify each finding by confidence level, and produce formal deliverables such as CAD drawings and survey reports.

Can PAS128 Surveys Be Carried Out On Live Sites Within The Swanscombe Area?

PAS128 surveys can be conducted safely and effectively on live sites in Swanscombe, including active construction zones, public highways, utility compounds, and operational facilities. 

Our teams are trained to work around live infrastructure and coordinate with site supervisors to minimise disruption.

Depending on the site, additional safety measures such as traffic management or permits to work near high-voltage assets may be required.

Surveys can also be phased or scheduled during off-peak hours to suit the access constraints of your project.

What Technologies Are Used To Perform PAS128 Surveys Near Swanscombe?

We use a range of advanced detection and positioning technologies in Swanscombe to ensure PAS128 survey compliance, including:

• Electromagnetic Locators (EML) – Used to trace metallic pipes and live electrical services accurately.
• Ground Penetrating Radar (GPR) – Essential for detecting non-metallic utilities such as plastic or concrete pipes and deeper services.
• GNSS (Global Navigation Satellite System) – Provides precise geospatial data to accurately position located utilities.
• Total Stations – Capture detailed site measurements for high-accuracy mapping and CAD integration.
• Vacuum excavation – Used for safe, physical verification of utility positions without damaging buried assets.
• CAD/GIS platforms – All data is processed into digital utility drawings, enabling clear, reliable planning and design.

How Do Surveyors Ensure Full PAS128 Compliance For Worksites In Or Around Swanscombe?

Surveyors working under PAS128 surveys in Swanscombe follow a structured workflow that includes pre-survey planning, desktop research, on-site detection, data classification, and report generation.

Each stage is documented, and all findings are classified using PAS128’s quality level codes, which indicate the certainty of a utility’s position.

Surveyors also document the method used to detect each utility—for example, whether it was identified using EML, GPR, or both.
