A utility survey involves the systematic investigation and mapping of underground utilities and services in a particular area. This type of survey's primary aim is to identify, locate, and map the various utility lines such as water mains, gas mains, electric cables, telecommunication lines, and sewer systems.
These surveys are critical in construction and development projects to prevent accidental damage to existing utilities. By using a combination of ground-penetrating radar, electromagnetic locators, and other latest technology, our surveyors can create accurate maps and reports detailing the location and depth of these utilities. The information gathered from these surveys helps in planning, design, and execution of projects to avoid potential disruptions, accidents, or costly damage to essential infrastructure. Please make contact if interested in this service.
At Plot. Surveys Ltd., we specialise in providing comprehensive utility surveys that are essential for the success of your infrastructure and development projects. Whether you are planning construction, excavation, or redevelopment, understanding what lies beneath the surface is crucial to avoid costly surprises and ensure a smooth project flow.

What is PAS 128? PAS 128 stands for Publicly Available Specification 128, a BSI standard used in the United Kingdom that provides guidelines for locating underground utilities. It offers a framework for managing utility infrastructure during excavation or construction projects. The specification categorizes the quality of location information about underground utilities into four defined levels (PAS 128 Quality Levels) ranging from D (Desktop) to A (Verification). These levels help ensure safety and reduce the risk of damaging underground utilities during construction or excavation work.
Here at Plot. Surveys Ltd we are able to provide surveys that are fully compliant with the BSI's PAS 128 specification.
PAS 128 Quality Levels:
Quality Level - A (Verified)
Horizontal and vertical location of the top, bottom or
centreline of the utility (to be indicated on drawings).
Visually verified position in a manhole chamber or trial hole for example.
Quality Level - B1 and B1P
Horizontal and vertical location of the utility detected by
one of the geophysical techniques used (EML or GPR)
Symmetrical electromagnetic field achieved resulting in peak and null
measurements within B1 tolerance and/or present in GPR
data where both depth estimates and horizontal location
can be confidently established to the required accuracies.
Quality Level - B2 and B2P
Horizontal and vertical location of the utility detected by
one of the geophysical techniques used (EML or GPR)
Symmetrical field achieved resulting in peak and null
measurements within B2 tolerance and/or present in GPR
data where both depth estimates and horizontal location
can be confidently established to the required accuracies.
Quality Level - B3 and B3P
Horizontal location only of the utility detected by one of
the geophysical techniques used.
EML field unable to estimate depth and horizontal
accuracies within B2 tolerances with confidence.
Features present within the GPR data that indicate the
presence of a utility but do not directly correlate to its
position (e.g. trench sides or fill detected by GPR without
positive identification of utility).
Quality Level - B4 and B4P
A utility segment which is suspected to exist (either on
QL-D or QL-C records) but has not been detected and is
therefore shown as an assumed route.
QL-C
A segment of utility whose location is demonstrated
by visual reference to street furniture, topographical
features or evidence of previous street works
(reinstatement scar).
QL-D
Copy of utility asset record only.

Here are several key reasons why customers, particularly those involved in construction, excavation, or development projects, should consider using utility surveys:
In conclusion, utility surveys are an indispensable tool for anyone involved in construction, excavation, or development projects. They enhance safety, save costs, ensure legal compliance, improve project efficiency, protect the environment, and provide valuable data for long-term planning.
