Thames Water Announce £4bn AMP7 Partners

Thames Water has agreed the final and biggest framework for design and build construction partners on its AMP7 programme.

The clean and wastewater projects will include schemes across London and the Thames Valley.

The frameworks are extendable into AMP8 and could see Thames award up to £4bn of investment to undertake work on all types of above and below ground assets.

Following the awards of frameworks in two lots earlier this year, five further lots of successful contractors have been announced.

John Bentley, Thames Water’s capital delivery director, said: “We have now appointed our partners to plug the final piece of the jigsaw for our AMP7 delivery.

“We have ambitious plans and are looking forward to working together to outperform expectations.”

The latest geographical frameworks follow on from lots announced in May and will run parallel to the Thames-wide frameworks.

Last year, Thames Water announced its decision to move away from an alliancing approach and implement an “intelligent client” operating model across its capital delivery function during AMP7.

This model will see the company bring more activities in-house in the key areas of asset management, programme management, project management, technical assurance and commercial management.

Work will be delivered through a series of delivery “runways” covering all of the capital programme and these latest frameworks will operate on Runway 2, the main delivery route.

To help deliver this ambition Atkins has been named Strategic Delivery Partner.

It will deliver asset management, project management and technical assurance services to support the utility’s transition, while Mace has secured a role as the Programme Management Office delivery partner.

This will see Mace assist Thames Water with programme management, quality assurance, business systems and processes and governance and risk.

Phil Cull, Southern Region Director at winner Barhale said: “We are immensely proud of our longstanding association and the confidence Thames Water continues to show in Barhale.

“We have worked with Thames since 1989 and have supported each AMP period. That depth of experience gives us real understanding of the challenges facing a network which serves the most densely populated part of the country.”
