Surveybase is a recognised leader in Underground Utility Surveying. With our nationwide service, we deliver accurate and reliable underground utility mapping solutions, helping clients mitigate risks, enhance safety, and ensure compliance, providing confidence in your project from the outset.

What projects can benefit from an underground utility survey?

Underground Utility Surveys are essential for a wide range of projects where accurate mapping of buried infrastructure is critical for safety, compliance, and efficiency. These include:

Architecture & Planning: Providing accurate underground utility data to inform site feasibility, master planning, and early-stage design decisions.

Construction & Development: Ensuring safe excavation and preventing costly utility strikes.

Infrastructure & Civil Engineering: Supporting the design and maintenance of roads, railways, bridges, and utilities.

Urban Regeneration & Redevelopment: Identifying underground services in complex built environments.

Utility Installation & Maintenance: Providing precise service locations for water, gas, electricity, and telecom networks.

Highways & Transport Projects: Mapping buried utilities to aid roadworks, expansions, and public transport upgrades.

Commercial & Residential Projects: Assisting architects, developers, and contractors in safe site planning.

Environmental & Drainage Surveys: Locating drainage systems and assessing flood risk.

What is an Underground Utility Survey?

An Underground Utility Survey is essential for accurately detecting, identifying, and mapping buried infrastructure, including gas, water, electricity, telecommunications, drainage, and sewer networks. Utilising advanced technologies such as Ground Penetrating Radar (GPR) and Electromagnetic Detection, these surveys provide precise data on the location, depth, and type of underground services.

Deliverables of an Underground Utility Survey include a comprehensive Desktop Utility Search Report, providing detailed information on local underground services, along with Utility Survey Plans or Models that map the exact location, depth, and type of underground infrastructure in relation to your site. These surveys help clients minimise risk, prevent costly utility strikes, and ensure the safe and efficient planning of construction, excavation, and infrastructure projects.

Four-Tier Survey Options

We offer a four-tier Underground Utility Survey service, including Desktop Utility Search Reports, Drainage Mapping, Utilities Services Detection, and a full PAS- 128 project management solution.

DESKTOP UTILITY SEARCH REPORT
A Desktop Utility Search Report is a preliminary survey that provides an overview of underground utilities in a given area, based on existing records. It includes information on the location, type, and depth of known services like gas, water, electricity, and drainage, helping with risk assessment and site planning. While not involving fieldwork, this report is valuable for identifying potential utilities and guiding further investigation.

DRAINAGE SURVEY
A drainage survey is a detailed inspection of a property’s drainage system, designed to identify potential issues such as blockages, leaks, or structural damage. Using advanced methods like rods and sondes, the survey detects the location and depth of the drainage system, providing essential insights into its condition and functionality. Drainage surveys are crucial for understanding the state of the system, ensuring it operates efficiently, and preventing costly repairs by detecting problems early. A drainage survey can include Manhole Asset deliverables for cover levels, chamber sizes, pipe details including; depths, materials, diameter and validated connectivity.

UNDERGROUND UTILITY SURVEY
An Underground Utility Survey provides a thorough assessment of the various utilities buried beneath a property or construction site, including water, gas, electricity, drainage, and telecommunications systems. The survey accurately locates and maps the position, depth, and type of underground utilities, making it crucial for safe construction, maintenance, and development projects. By identifying and understanding the layout of these utilities, the survey helps avoid accidental strikes, reduces risks, and ensures compliance with safety regulations

PAS 128 UTILITY SURVEY
A PAS 128 survey is a comprehensive and standardised survey designed to accurately identify and locate underground utilities, following the PAS 128:2022 standard. This survey provides critical data on the position, depth, and type of underground utilities, including water, gas, electricity, telecommunications, and drainage systems. The survey uses advanced techniques such as electromagnetic location (EML), ground- penetrating radar (GPR), and direct exposure methods to deliver precise and reliable results.

Frequently asked questions

An underground utility survey is important before construction to accurately locate buried services and avoid costly damage, delays, or safety risks. It helps ensure that excavation and building work can proceed safely and efficiently, reducing the chance of striking pipes, cables, or other critical infrastructure.

If you are planning excavation, construction, or redevelopment, a utility survey is highly recommended. It helps prevent damage to underground services, ensures safety, and avoids costly delays. If your project involves digging near roads, buildings, or existing utilities, a survey will provide accurate data to reduce risks and ensure compliance with regulations.

The cost of a Utility Survey depends on several factors, including the size of the site, complexity, location, and required detection methods (such as Ground Penetrating Radar or Electromagnetic Detection). Each project is unique, so pricing varies based on specific requirements. For a free, no obligation quote, please contact us today.
