The arrangements for the submission of tenders and requests to participate shall be determined by the contracting authority, which may choose an exclusive method of submission. Tenders and requests to participate may be submitted by letter or by electronic means. Requests to participate may also be submitted by fax. The means of communication chosen shall be generally available and shall not restrict the access of economic operators to the procurement procedure. The means of communication chosen shall be such as to ensure that the following conditions are satisfied: each submission contains all the information required for its evaluation; the integrity of data is preserved; the confidentiality of tenders and requests to participate is preserved and the contracting authorities examine the content of tenders and requests to participate only after the time limit set for submitting them has expired; the protection of personal data in accordance with the requirements of Regulation (EC) No 45/2001. Where necessary for the purposes of legal proof, the contracting authorities may decide that requests to participate submitted by fax must be confirmed by letter or electronically as soon as possible and at all events before the final date set in Articles 152.
