To avoid confusion, please note that the "ATORs" are not the same as the "Case Study". Annex 5a is a "Case Study" and Tenderers should only provide the deliverables contained therein. Information provided in Annex 5a will be used as a basis for evaluating the Tender from a technical perspective. A "comprehensive schedule of delivery" and a "maximum budget" come into force, on the basis of "Assignment Terms of Reference" (or ATORs), nonly once the Framework Agreement has been signed. Section 4. of Annex 4 provides the Description of Services and Deliverables to be produced by the economic operators, who will be awarded a Framework Agreement. Annex 4 (Terms of Reference or TORs) will actually form part of the contractual documentation of the Framework Agreement as Appendix A.
