two.1.4) Short descriptionII.1.4) Short description
West Northamptonshire Council (the “Authority”) is seeking one or more suitably qualified and experienced suppliers to deliver the following services: Treatment & Disposal of Residual Waste; and Management of Household Waste Recycling Centre Services. The scope of these services is further detailed in the procurement documents made available on publication of this notice and in the Lot specific descriptions further below.
Bidders should note that the scope of the services may change during the life of the eventual contract(s). Where the nature of any change is known at this time then the Authority has detailed this in the procurement documents.
This procurement is being undertaken using the competitive dialogue procedure under the Public Contracts Regulations 2015.
The procurement is divided into three (3) Lots:
Lot 1: Treatment & Disposal of Residual Waste (“Residual Service”);
Lot 2: Management of Household Waste Recycling Centre Services (“HWRC Service”); and
Lot 3: Treatment & Disposal of Residual Waste and; Management of Household Waste Recycling Centre Services
The Authority intends to award a single separate contract for each of the Residual Service and the HWRC Service. This will be the case even if the same bidder is appointed to both services.
Lot 3 has been included as an optional Lot to enable a bidder to identify the financial saving or discount that would apply if they are awarded both services. It is not intended as an option for providing a combined service and the Authority would still award two separate contracts. For the avoidance of doubt, the Authority has not designed this procurement with the intention that the same bidder must be successful for both services.
Bidders should note that they may submit for one or both of Lots 1 and 2. A bidder may only submit for Lot 3 where they have submitted for Lot 1 and Lot 2 or they have submitted for only one of Lot 1 or Lot 2 but are submitting a joint bid for Lot 3 with another bidder who has bid for the other of Lot 1/Lot 2.
Further detail on the approach to managing the Lots during the procurement process is set out in the procurement documents. Final award will be made in accordance with the award criteria and evaluation approach set out in the procurement documents. If Lot 3 is awarded, then Lots 1 and 2 will not be awarded (and vice versa).
The Authority will apply the selection criteria outlined in the procurement documents to limit the number of bidders taken through to the dialogue stage as further detailed below and in the procurement documents.
The Authority does not intend to reduce the number of bidders down further during the dialogue stage by applying the award criteria.
