What Types of Utility Surveys (PAS 128) Are Available?
In , we offer several types of utility surveys (PAS 128) to meet different project needs:
Type A (Verification): This involves hand-dug trial holes to verify utility positions accurately. It is ideal for projects requiring precise validation of utility locations before excavation. Our team uses calibrated surveying equipment to ensure measurements meet the PAS 128 standard.
Type B (Detection): This employs techniques such as ground-penetrating radar (GPR) and electromagnetic location (EML) to accurately map subsurface utilities. Type B surveys help identify the presence of cables, pipes, and other infrastructure, reducing the risk of service strikes during construction.
Type C (Site Reconnaissance): Involves visual inspection and reviewing existing records to gather initial site information. This type is typically used at the preliminary stages of planning, providing a general overview of the utilities present.
Type D (Desktop Study): Compiles utility data from existing records and maps. Often the first step in the survey process, it aids in planning further detailed surveys by identifying known utility paths and potential obstacles.
These surveys ensure comprehensive utility management, safeguarding both public and private projects. Contact us to discuss the most suitable survey type for your needs.
What Projects Are Utility Surveys (PAS 128) Suitable For?
Our utility surveys (PAS 128) are ideal for a wide range of projects, including construction, renovation, and infrastructure development. These surveys ensure accurate detection of utilities such as water mains, gas pipelines, electrical cables, telecommunications lines, and drainage systems.

How Does Utility Surveys (PAS 128) Work?
Here's how our utility surveys (PAS 128) process works:
Initial Consultation: We discuss your project requirements and collect existing utility records to gain a understanding of the site. We also consider factors such as site history and previous surveys to inform our approach.
Site Investigation: Our team conducts on-site surveys using ground-penetrating radar (GPR) and electromagnetic locators to identify subsurface utilities. This phase examines depths up to three metres, helping us detect utilities like water mains, gas pipes, and telecommunications cables.
Verification: Hand-dug trial holes verify utility locations and depths. This confirms the data and helps ensure compliance with safety standards such as the Health and Safety Executive (HSE) guidelines.
Reporting: We provide a detailed report of all findings, including maps and utility positions. The report also includes recommendations for mitigating any identified risks and ensuring compliance with regulations such as PAS 128.
Our surveys are suitable for a wide range of clients, including property developers, construction firms, and utility companies.
How Long Does Utility Surveys (PAS 128) Take?
Most utility surveys (PAS 128) take between two to five days, depending on the site's size and complexity. This timeline accounts for thorough data collection and analysis using equipment such as ground-penetrating radar (GPR) and electromagnetic locators, both crucial for identifying and mapping subsurface utilities accurately.
Factors affecting the duration include weather conditions, access restrictions, and the volume of subsurface utilities. Additionally, time may be required to comply with health and safety standards, such as the CDM (Construction Design and Management) Regulations 2015, ensuring the safety of both our team and your property.
We maintain regular communication with clients throughout the process to accommodate any site-specific requirements. A full schedule will be provided during the initial consultation.
