Proposal for the award of three contracts for the supply of qualifying prototypes for switch-mode power converters with variable bipolar output for the LHC

This document concerns the award of three contracts, each for the design, documentation, manufacture, factory testing and delivery of one qualifying prototype four-quadrant switch-mode power converter at ± 600 A, ± 10 V and one qualifying prototype four-quadrant switch-mode power converter at ± 600 A, ± 40 V. Following a market survey carried out among 66 firms in fifteen Member States, a call for tenders (IT-2847/SL/LHC) was sent on 22 March 2001 to six firms and one consortium, consisting of two firms, in six Member States. By the closing date, CERN had received four tenders from three firms and the consortium in five Member States. The Finance Committee is invited to agree to the negotiation of contracts with two firms and one consortium for the design, documentation, manufacture, factory testing and delivery of one four-quadrant switch-mode power converter at ± 600 A, ± 10 V and one four-quadrant switch-mode power converter at ± 600 A, ± 40 V: 1) JEMA (ES) for a total amount of 144 128 euros (220 717 Swiss francs), not subject to revision. The rate of exchange that has been used is that stipulated in the tender. 2) The consortium CIRTEM (FR)/ EEI (IT) for a total amount of 257 307 euros (397 128 Swiss francs), not subject to revision. The rate of exchange that has been used is that stipulated in the tender. 3) TRANSTECHNIK (DE) for a total amount of 304 483 euros (467 070 Swiss francs), not subject to revision. The rate of exchange that has been used is that stipulated in the tender. The firms have indicated the following distribution by country of the contract values covered by this adjudication proposal: JEMA: ES - 45%; DE - 20%; NL - 15%; CH - 10%; SE - 5%; Others - 5%; CIRTEM/EEI: IT - 60%; FR - 40%; TRANSTECHNIK: DE - 90%; CZ - 10%.
