National Underground Assets Group
The National Underground Assets

Formed in 2005 to act as a point of focus and single voice for everyone involved with underground assets
A total length of over 4 million km…and growing daily!

Assets can be found anywhere:
…and away from the street
both under the street …
… and “Plans or other suitable information about all buried services in the area should be obtained before excavation work starts… “ (HSG47)
Around 4 million works are carried out in the street each year PLUS up to another 1 million works away from the street …
That’s where the problems can start!
• Records of underground assets may be incomplete and inconsistent
• There is no standard approach to sharing records
• Current locating technologies are not 100% effective
All of which can lead to • Extended job times• Abortive and unnecessary work• Damage to third party assets, estimated at £150
million per year (2005)• Risk to safety of workers and to the public
Resulting in• Societal costs, including costs of delays to road users, disruption to business, environmental damage and safety costs, which total an estimated £5.5 billion per year (2005)• Consequential loss of supply or service• Damage to brand image and reputation
All information on underground assets, and associated above ground assets, will be shared between stakeholders in a consistent way, on demand
The NUAG Vision
NUAG has published three reports, each based on extensive stakeholder involvement, setting out what is needed to help achieve the Vision. These are available at www.nuag.co.uk
