Mapping Critical Subsurface Infrastructure.
Our Underground Utility Surveys provide accurate mapping of vital subsurface services. Avoid costly disruptions and ensure worker safety by identifying utilities that exist on site. Our services include site mark out, utility plans, topographical survey mark up, radio detection, and ground-penetrating radar (GPR).
The location of Underground services is often overlooked when developing a site. However it is a critical factor in any development – the sheer cost and time scale involved in re-routing services or damaging services can have a huge effect on the viability of a scheme. It is also vitally important to locate existing services to ensure workers safety when digging onsite. This is where a Utility Survey is useful.
Site Mark Out
Understanding our clients’ utility survey needs is important to our staff to make sure they receive the service they expect. By doing this we can make sure the client is getting the survey they require, on time and within the required budget.
This survey can be useful usually in conjunction with the mark up on the topographical survey as it lets people know exactly where the services are located on the ground. Each service is individually marked on the ground with either spray paint or pegs which provides a visual identification of the services buried below.

Utilities Service Plans
Utility company’s asset plans are also used to build up a picture of the utilities on site. They are used in conjunction with the above methods to make sure nothing is missed.
Once the services have been located there are a number of deliverables that can be provided below:
Topographical Survey Mark Up
We can provide all of the services on a topographical survey either supplied by us or by you. Each individual service is layered separately to either our layering system or specified by the client. The revised topographical survey is then presented digitally in AutoCAD format and also as a paper plot.
Radio Detection
The latest Radio Detection equipment is used along with signal generators so that we can locate metal objects and provide details of the service locations.
Ground Penetrating Radar (GPR)
Where non-metallic pipes, such as plastic or asbestos cement, are detected, we use Ground Penetrating Radar to indicate the presence of services and voids.
Utilities Survey Overview
All our Underground Utilities Surveys are PAS128 Specification compliant, including the provision of Desktop Utility Studies. Fundamentally no matter what level of service you require the survey will assist in identifying all underground services. The survey can be provided as a standalone project or integrated into a wider scheme to include Topographical and CCTV Surveys.
