Multi-party framework agreement contracts will be awarded primarily using the cascade solution, with mini tenders operating in limited circumstances. Through application of the cascade method whereby contracts are awarded on foot of the original tenders to the first ranked firm admitted to the framework agreement. Where they are not able to deliver the contract due to availability, etc. the next ranked firm will be approached moving in ranked order through the Framework Members until the contract is awarded. Through invitation to a mini-tender of all the firms admitted to the framework agreements. On each occasion, a Supplementary Request for Tender will be issued detailing the scope of requirements, the award criteria, a closing date and time and methodology for submission of responses.
