Description
Thames Water wishes to award a number of framework agreements to suppliers capable of project design, building renovations, remedial works and/or the provision and maintenance of welfare cabins.
Due to the varying age of buildings and structures within the Thames Water estate (over 400 sites across the TW supply area), there is need to carry out renovation and remedial works in order to ensure they remain safe and fit for purpose. The Framework Agreements will cover the following works: Consultancy (Project Design), Internal & External Works to operational and corporate buildings (London area), Internal & External Works to operational and corporate buildings (Thames Valley and Home Counties), Roofing, Asbestos Consulting, Asbestos Treatment and Welfare Cabins.
Thames Water reserve the right to issue multiple awards for each lot in this agreement to achieve the most efficient and economical service solution whilst ensuring the security and consistent continuity of supply and delivery. Thames Water reserve the right to enter into a contract or contracts for the provision of all or any number of lots.
In parallel, although on a slightly different timetable, Thames Water is also running a procurement exercise for facilities management services whereby there are some common areas of work with this procurement exercise.
We expect to issue the notice early December 2025 with a response date 6 weeks after issue.
