Portsmouth, UK, September 19, 2007: Geospatial data collection company Yotta DCL is providing surveying services to major highways organisation Colas as part of a 25-year contract with the UK’s Portsmouth City Council. This contract, worth USD1000 million, puts Ensign Highways Limited, a division of Colas, in the driving seat for delivering sustainable strategies for a 450 km road network, with Yotta DCL providing highways condition and patching surveys.
This is the first time that such a PFI (Private Finance Initiative) project has led to a UK local authority working with a commercial organisation to provide comprehensive highways management on this scale. The rules of engagement, however, are rigorous with Yotta DCL performing independent surveys every six months on principal and secondary roadways to prove that Ensign Highways is improving the condition of the network. These improvements are measured against the Network Condition Index developed by Portsmouth.
Yotta DCL is undertaking both CVI (coarse visual inspection), DVI (detailed visual inspection) and patching surveys as part of the complex, complete inspection of roadways to ascertain Ensign Highway’s rehabilitation performance. The survey specialist has also assisted Ensign Highways to develop a novel patching survey that utilises CVI-type techniques. The patching survey is an obligation of the contract that gives Portsmouth a clear picture of the quantity and quality of remedial repairs to road surfaces.
Eric Brangier, Highways Manager, Ensign Highways, said: “This is an extremely important contract that requires Ensign Highways to prove that progress is being made. Yotta DCL gives us the independent view that assists us to demonstrate to Portsmouth City Council that our road rehabilitation programme is on track and delivering.”
