Four contractors will share a £1bn jackpot of AMP6 work from Thames Water.
Joint ventures of Kier/Clancy Docwra and Morrison Utility Services/J Murphy & Sons have been appointed by the utility giant for asset management period six.
Known respectively as KCD and Agility, the two teams will be responsible for construction, maintenance and logistics works, as well as customer services, for the next five years.
The deals, which will begin in April 2015, could be extended for a further 10 years, throughout AMP7 and AMP8.
Kier chief executive Haydn Mursell said: “With this contract, Kier further demonstrates its strengthened integrated construction and services capabilities following the acquisition of May Gurney last year.
“Through our joint venture with Clancy Docwra, we will be able to support Thames Water in this innovative new alliance, helping them to maximise the performance of their estate and their assets for the benefit of their customers.”
Drew Ritchie, director of Agility, said: “This is a fantastic opportunity to partner with Thames Water to drive up standards in safety, further improve customer service and deliver efficiencies through innovation, sustainability and best practice.”
Thames Water managing director of wholesale water Bob Collington said: “We strongly believe these two alliances will create aligned goals and objectives throughout the supply chain, standing us in the best possible position to deliver our customer and stakeholder promises.
“I am determined to ensure that investment and delivery are customer-focused at all times. By bringing greater innovation to process and techniques, I hope we can build on the past to improve performance further in the future.”
