S.L. 601.5 Art. 161Invitation of admissible tenders.

(1) All tenderers that have submitted admissible tenders shall be invited simultaneously to participate in the electronic auction using, as of the specified date and time, the connections in accordance with the instructions set out in the invitation. The electronic auction may take place in a number of successive phases. The electronic auction shall not start sooner than two working days after the date on which invitations are sent out.

(2) The invitation shall be accompanied by the outcome of a full evaluation of the relevant tender, carried out in accordance with the weighting provided for in regulation 170(7), (8), (9).

(3) The invitation shall also state the mathematical formula to be used in the electronic auction to determine the automatic re-rankings on the basis of the new prices and, or new values submitted. Except where the most economically advantageous offer is identified on the basis of price alone, that formula shall incorporate the weighting of all the criteria established to determine the most economically advantageous tender, as indicated in the notice used as a means of calling for competition or in other procurement documents. For that purpose, any ranges shall, however, be reduced beforehand to a specified value.

(4) Where variants are authorised, a separate formula shall be provided for each variant.
