Two top executives of the public company responsible for Tres Grande Bibliotheque project in Paris have been charged with breaching tendering legislation.It follows controversy over alleged favouritism in the award of construction contracts.Dominique Jamet and Serge Goldberg requested that charges be brought so that they could examine the evidence against them.A complaint was lodged with the French courts in September 1991 by a group of construction companies, led by CBC, which claimed they had been unfairly treated when in bidding for work on the TGB.This followed the announcement that Bouygues had been awarded contracts worth £140 million for work on the new national library.M Jamet said: 'The complaint is irresponsible and improper. We have kept to the rules and have nothing to be reproached for.' But CBC company secretary, Renaud Bentegeat claims his group was the best-placed of the candidates in terms of costs and deadlines.The group has given up all chance of getting the tenders resubmitted now building has started, but hopes to recover millions of francs in tendering costs.Soon after CBC's original complaint in September 1991 the government body which oversees public procurement in France, found irregularities in tendering for one of the seven contracts awarded to Bouygues and ordered it to be re-tendered. It was eventually awarded to another firm. Bouygues refused to comment on the charges.
