PAS128 Utility Survey
PAS128 Utility Survey
The Significance of Utility Searches
At GeoCart, we recognise the crucial role that desktop utility searches play in the successful execution of underground utility surveys. This process, an integral component of pre-construction and renovation planning, involves detailed communication with major utility providers, including gas, electricity, telecommunications, water, and sewerage services. Our goal is to procure detailed plans that accurately represent the distribution of these utilities within and around your project site.
What is a PAS 128 Utility Survey?
The PAS 128 utility survey is a specific standard for underground utility detection, verification, and location in the UK. Developed by the British Standards Institution (BSI), it provides a detailed framework for the type and quality of utility information that should be provided at each stage of detection, from desktop utility records search to full excavation.
his standard ensures a high level of accuracy and consistency in surveying underground utilities, reducing the risk of damage and improving safety during excavation and construction projects. It categorises the quality of data into different levels, from QL-D (lowest level of detail based on existing records) to QL-A (highest level involving physical identification).
Detailed Mapping and Planning for Effective Project Execution
The information obtained typically comes in the form of extensive CAD drawings. These drawings provide a comprehensive depiction of the utility infrastructure in the specified area. The data gathered allows for:
- Informed decision-making regarding upcoming construction or renovation activities.
- Integration strategies for connecting new developments to existing utility services.
- A thorough understanding of the site prior to initiating any physical ground investigations.
In instances where utility services are not represented on the provided plans, our team collaborates with both local and national utility providers to gather as much pertinent information as possible. It’s crucial to acknowledge that certain utility services may remain undiscovered until physical ground investigations are conducted.
Preventing Potential Issues and Minimising Disruptions
By conducting thorough utility searches prior to the commencement of any physical work, we aim to:
- Save time and reduce costs by preventing errors and rework.
- Minimise disruptions during construction by identifying potential underground hazards and planning accordingly.
GeoCart is committed to offering exhaustive information, aiding our clients in making well-informed decisions, whether for initial planning stages or for on-site physical work.
