In such a case,  the contracting authority may award the tender to the next lowest tenderer or cancel the  tender procedure.  The contracting authority may waive the obligation of any candidate or tenderer to submit  the documentary evidence referred to above if such evidence has already been submitted for  the purposes of another procurement procedure, provided that the issue date of the  documents does not exceed one year and that they are still valid. In this case, the candidate  or tenderer must declare on his/her honour that the documentary evidence has already been  provided in a previous procurement procedure and confirm that his/her situation has not  changed.  Documentary evidence of the financial and economic capacity and/or of the technical and  professional capacity according to the selection criteria specified in the additional  information about the contract notice shall be submitted. (See further Section 2.6.11. of the  practical guide). By submitting a tender, each tenderer accepts to receive notification of the outcome of the  procedure by electronic means. Such notification shall be deemed to have been received on  the date upon which the contracting authority sends it to the electronic address referred to in  the offer.  22.4 The contracting authority reserves the right to vary quantities specified in the tender by +/-  100 % at the time of contracting and during the validity of the contract. The total value of the  supplies may not, as a result of the variation rise or fall by more than 25 % of the original  financial offer in the tender. The unit prices quoted in the tender shall be used. 22.5 Within 30 days of receipt of the contract signed by the contracting authority, the selected  tenderer must sign and date the contract and return it, with the performance guarantee (if  applicable), to the contracting authority. On signing the contract, the successful tenderer will  become the contractor and the contract will enter into force.  22.6 If it fails to sign and return the contract and any financial guarantee required within 30 days  after receipt of notification, the contracting authority may consider the acceptance of the  tender to be cancelled without prejudice to the contracting authority’s right to seize the  guarantee, claim compensation or pursue any other remedy in respect of such failure, and the  successful tenderer will have no claim whatsoever on the contracting authority.  22.7  The performance guarantee referred to in the general conditions is set at 10% of the amount  of the contract and must be presented in the form specified in the annex to the tender dossier.  It will be released within 45 days of the issue of the final acceptance certificate by the  contracting authority, except for the proportion assigned to after-sales service. 23.
