Treatment & Disposal of Residual Waste; and Management of Household Waste Recycling Centre Services

West Northamptonshire Council (the "Authority) sought 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 the services was further detailed in the procurement documents made available on the publication of the contract notice and these procurement documents were further refined during the procurement process.

The scope of the services may change during the life of the eventual contracts. Where the nature of any change was known to the Authority then this was detailed in the procurement documents.

The procurement was undertaken using the competitive dialogue procedure under the Public Contracts Regulations 2015. A separate contract was to be entered into for each of the Residual Service and HWRC Service, even if the same bidder was appointed to both services.

Lot 3 was included as an optional Lot to enable a bidder to identify the financial saving or discount that would apply if they were awarded both services. It was not an option for a combined service and if awarded would still have resulted in two separate contracts.

Bidders were able to submit a tender for one or both of Lot 1 and Lot 2. Bidders could only submit for Lot 3 where they submitted for Lot 1 and Lot 2 or where they submitted for only one of Lot 1 or Lot 2 but submitted a joint bid for Lot 3 with another bidder who has bid for the other of Lot 1/Lot 2.

The procurement documents set out the approach to managing the Lots with final award to be made in accordance with the award criteria. If Lot 3 was awarded, then Lots 1 and 2 would not be awarded (and vice versa).

By applying the award criteria, the Authority awarded Lots 1 and 2. Lot 3 was abandoned at award stage with no award made.

The figures included for overall and Lot specific values of the procurement correspondence to the original estimated values contained within the contract notice. The contracts for each of Lot 1 and Lot 2 contain a mix of fixed and variable sums payable and so it is not possible to include a fixed value of the contracts.

The variable elements relate to tonnages of relevant contract waste and no guarantee is given on volume or composition. As per the contract notice, the values stated in this notice exclude VAT and indexation.

To accept and treat residual municipal waste collected by the Authority including (without limitation) kerbside collected, bulky waste, household waste recycling centre waste, fly-tipping and persistent organic pollutants. To operate Brackmills Waste Transfer Station as a Delivery Point for residual waste, and to arrange for the haulage of waste from Brackmills and two other Delivery Points within West Northamptonshire to the treatment destinations.

The location of delivery points may change during the term. The contract is an exclusive arrangement for all in scope contract waste subject to certain rights of the Authority and exclusions under the contract (including relating to performance).

No guarantee is given on tonnage or composition. At contract notice and considering the existing service scope, options to expand service scope and the maximum term, the Authority estimated a total valuation at £162,000,000 with an estimated average spend per annum over the full term of approximately £10,000,000 (not to be taken as the budget for year 1 of delivery).

The estimated annual spend was based on forecast tonnages and estimated gate fees. The actual spend will be dependent on tendered gate fees, inflation and actual tonnages The contract will have a term of fifteen (15) years from 1 April 2025 with an Authority only break option at the end of year 10.

To manage the household waste recycling centre (HWRC) services, currently provided at 6 locations within West Northamptonshire, and arrange for the treatment of waste collected from the sites, with the exception of residual waste which will be treated under a separate contract. The services also include maximising the capture and resale of reusable materials collected at the HWRCs and via the bulky kerbside service.

The Authority reserved the right to remove the reuse element during the procurement but did not exercise this right. Not guarantee is given on tonnage or composition.

At contract notice and considering the existing service scope, options to expand service scope and the maximum term, the Authority estimated a total valuation of £75,000,000 with an estimated average spend per annum over the full term of £5,000,000 (not to be taken as the budget for year 1 of delivery). At contract award, as noted above it is not possible to give a fixed contract value but the award is within scope of the estimated value of the procurement. The contract will have a term of fifteen (15) years from 1 April 2025 with an Authority only break option at the end of year 10.
