Proposal to Negotiate an Amendment to an Existing Contract for the Design and Realisation of the Two End-Cap toroids for the ATLAS Experiments

This document concerns the proposal to negotiate an amendment to an existing contract for the design and realisation of the two end-cap toroids for the ATLAS experiment. For the reasons explained in this document, the Finance Committee is invited to agree to the negotiation of an amendment to the contract for the two end-cap toroids with RUTHERFORD APPLETON LABORATORY (RAL) (GB) for an extension of the scope of work for an amount exceeding the previously approved amount of 13 346 700 Swiss francs, subject to revision for inflation, bringing the total contract amount to 15 446 700 Swiss francs, subject to revision for inflation. The cost of this work is to be covered by the ATLAS Common Fund. CERN's contribution to the funding of this amendment will not exceed 420 000 Swiss francs.
