THREE consortia have emerged successful from a batch of 10 bidders to clinch five-year deals, worth £500 million in total, with Thames Water for work on its water and wastewater treatment sites.
The winning groups are: M J Gleeson/Montgomery Watson;
Laing/Hyder; and Costain/Binnie Black & Veatch.
The alliance agreements cover three quarters of the utility's capital works.
Gleeson is covering the west of Thames Water's region, Laing will work in the North-East, and Costain has London and the South-East.
Steve Lunn, Thames Water's engineering director, said: 'We will be applying our previous positive experience of partnering agreements to develop the advantages of this approach.'
The contracts are intended to maximise value and bring about better time management, cash flow and earlier involvement of key suppliers.
