Works for complete or part construction and civil engineering work

Tender description

Thames Water are looking for a number of partners to help us achieve our aim of increasing the efficiency of slow sand filter beds and rapid gravity filters through effective repairs and refurbishments and good quality media. Please note that the scope of these agreements does not include the supply of granular activated carbon (GAC). We have split our requirements into lots: Lot 1: Media removal and replacement; Lot 2: Slow sand filter bed refurbishment; Lot 3: Floor blocks for slow sand filter beds; Lot 4: Slow sand filter media; Lot 5: Rapid gravity filter bed refurbishment; Lot 6: Rapid gravity filter media. Specifications for each lot are given in the procurement documents (draft ITN) along with some heads of terms although these are not yet finalised. Bidders can apply for more than one lot and can submit commercial bids for individual lots as well as variant bids for combined lots. More detail on commercial schedule completion will be given in the procurement documents. Successful suppliers under this lot will be responsible for the removal of media from the slow sand filter beds (before the refurbishment work begins) and the installation of media after the refurbishment work is complete. Note that this activity is also undertaken by in-house teams and this agreement would be used as additional capacity. Suppliers under this lot will need to work closely with both TW site personnel and the slow sand filter refurbishment suppliers in order to minimise the amount of time that the slow sand filter beds are out of action for. Suppliers will need to provide their own machinery for removing the media and GAC although they will not need to dispose of the media. There will be a designated area on each site for media storage until it is either replaced in the beds or disposed of. Note that this lot does not include the supply of any media. We aim to appoint a single supplier for this lot. The value below is an estimate, over the maximum term of the agreement, based on expected spend.
