A joint venture of Costain, Atkins and Veolia Water has been appointed as design and build consortium to Thames Water’s AMP6 programme, which is worth up to £3 billion.
The JV has been appointed to an initial two-year Early Contractor Involvement [‘ECI’] contract and will then agree a five-year contract to deliver the AMP6 capital programme from 2015 to 2020. The contract may then be extended for a further five years from 2020 to 2025, as part of AMP7.
The alliance will deliver a significant proportion of Thames Water’s programme of essential upgrades to water and wastewater networks and treatment facilities across the capital.
The contract is worth approximately £450 million to Costain.
Andrew Wylie, Chief Executive of Costain, commented:
“We are delighted to have been selected by Thames Water to deliver this major AMP6 contract.
“The award is a consequence of our ability to work collaboratively, deliver sustainable innovative solutions to major infrastructure needs, and provide value for money. It also further reinforces Costain’s position as one of the leading UK engineering service providers in the water sector.”
Prof Dr Uwe Krueger, Atkins' chief executive officer, said:
“This important addition to our strong portfolio of clients is further evidence of the strength of the UK water market and will help smooth the transition between the cyclical funding periods so that key skills and capabilities are retained within the sector.”
