Proposal for the award of a contract for the supply, assembly and testing in liquid helium of bypass-diode stacks for the LHC magnets

This document concerns the award of a contract for the supply, assembly and testing in liquid helium of 1250 dipole and 400 quadrupole bypass-diode stacks. Following a market survey carried out among 61 firms in eleven Member States, a call for tenders (IT-2648/LHC/LHC) was sent on 7 July 1999 to thirteen firms and one consortium consisting of two firms, in six Member States. By the closing date, CERN had received eleven tenders. The Finance Committee is invited to approve the negotiation of a contract with the firm O.C.E.M. (IT), the lowest bidder after realignment, for the supply, assembly and testing in liquid helium of 1250 dipole and 400 quadrupole bypass-diode stacks for a total amount of 6 591 369 Swiss francs, subject to revision, with an option for the supply, assembly and testing in liquid helium of up to 125 dipole and 40 quadrupole bypass-diode stacks, for a total amount of 620 990 Swiss francs, subject to revision, bringing the overall total amount to a maximum of 7 212 359 Swiss francs, subject to revision. The firm has indicated the following distribution by country of the work covered by this adjudication proposal: IT-91%, DE-9%.
