Underground Utility Detection
Underground utility detection surveys are recommended before breaking ground to assist in complete worker safety. All of our Underground Utility Detection (UUD) surveys meet industry standards and we are able to provide all levels of PAS128 quality levels for our in-house services. Our UUD surveys are internationally awarded and recognised for their quality and innovative approach.
PAS 128 - Survey Quality Types
PAS 128 is the latest specification for underground utility detection, verification and location. PAS 128 creates a common environment for both the client and contractor to specify, survey and deliver data.

Desktop Utility Records Search
Downtime can sometimes occur due to the late arrival of DURS. Catsurveys’ specialised DURS team can reduce delays during the Underground Utility Detection process and provide information quickly and efficiently to our clients.
QL-C
Site Reconnaissance
Before beginning an Underground Utility Detection survey, our team can walk the site and provide a Custom Street View (CSV). This allows us to visually identify any potential hazards from surface level which we can feedback before further Underground Utility Detection takes place.
QL-B
Detection
Multiple Underground Utility Detection procedures can take place to provide the most accurate and detailed mapping. This includes GPR and EML detection which are methods of non-invasive Underground Utility Detection.
QL-A
Verification
Underground Utility Detection begins with manhole reporting and verification of all manholes that could affect the specified area. This Underground Utility Detection method can be extended beyond the site boundaries if required.
How is an Underground Utility Detection Carried Out?
All of our utility surveyors use the most up to date precision locators and Ground Penetrating Radar available. Using different methods we can locate/detect metallic pipes and cables. With the addition if various attachments and accessories, we can locate drains, sewers and empty ducts. With all methods and accessories we can give reliable horizontal and vertical locations.
