NEC4 ECSS Short form with TW Amendments
Optimisation, structural replacement or relining of distribution water mains within DMAs and bounded by district meters and the District Boundary Valves.
Structural replacement of all service connections from the distribution mains to customer boundaries, including installation of a suitable boundary box.
Replacement of all apparatus connected to the network including valves, hydrants, disinfection points, air valves, etc.
Securing abandoned mains by cutting and capping. Removing surface covers, marker posts and plates of abandoned washouts, hydrants and valves etc. so that only covers relating to live apparatus remain. → We would like to inform that the PQQ FA2172 Main Rehab Framework Lot 2 process is being terminated due to a lack of candidates. Lot 2 was structured as a multi-supplier framework with 3 to 5 contractors.
Since we received only one Lot 2 PQQ response it is not possible to proceed at this stage with a tender process for Lot 2 that is consistent with the Contract Notice.
The limited number of submissions received would additionally not provide the necessary competitive environment required to ensure the best value for money.
This decision has been made in accordance with our procurement process, which aims to foster a competitive and fair bidding process.
We believe that re-evaluating the scope of the ITN and possibly re-issuing it at a later date may attract a broader range of suppliers and ensure a more competitive process.
