Member Rebate - Supporting Carbon Reduction:
To support Contracting Authorities with the additional investment required when acquiring Full Battery Electric and Hydrogen Fuel Cell Electric vehicles with 8 or more passenger seats (not including electric/internal combustion hybrids, mild hybrids or internal combustion engine vehicles), 25% (equating to 0.25% of the total Capital Cost) of the framework fee generated under Lots 1 - 4 shall be disbursed by the Agent back to the Contracting Authority that has purchased said Vehicle(s) using this Framework.
Framework operation description
This Framework is intended to be used by Contracting Authorities, who may access without competition between the suppliers. Clause 9.2 of the Framework Agreement details the objective mechanism to award a Call-Off Contract to a Supplier without competition, as per section 45(4) of the Act.
Suppliers will be ranked within each of the Lots of the Framework based on their overall score. However, due to the range of chassis and completed vehicles available within each Lot, the Suppliers are sub-ranked based on the individual chassis or vehicle type that has been listed within the framework cost submission. Therefore, where the 1st ranked Supplier in the Lot has not submitted a price for a given vehicle or chassis the next highest ranked Supplier becomes the first ranked Supplier for that vehicle or chassis type.
The Framework may also be accessed by Contracting Authorities to award Call-Off Contracts following completion of a Competitive Selection Process, as per section 46 of the Act. The Competitive Selection Process to be used under the Framework is detailed within Clauses 9.3 to 9.7 of the Framework Agreement.
Goods and associated services that may not be easily identifiable as part of this tender document can be specified by individual Members during their call-off processes. Therefore, other goods and services that are related to the focus of this Framework are expected to be provided as part of this Framework within the closest relevant Lot(s). This is subject to alignment with the scope and objectives of the relevant Lot(s).
Award method when using the framework
