Before the contracting authority signs the contract with the successful tenderer, the successful tenderer must provide the documentary proof  or statements required under the law of the country in which the company (or, for consortia, each of the companies) is established, to show that it does not fall into any of the exclusion situations listed in Section 2.6.10.1. of the practical guide. This evidence, documents or statements must carry a date, which cannot be more than one year before the date of submission of the tender. In addition, a statement must be furnished stating that the situations described in these documents have not changed since then. The above-mentioned documents must be submitted for the tenderer, every member of a joint venture/consortium, all subcontractors providing more than 10 % of the works and every supplier providing more than 10 % of the works. For any other subcontractor or supplier, the successful tenderer must submit a declaration from the intended subcontractor or supplier that it is not in one of the exclusion situations. In the event of doubt on this declaration of honour, the contracting authority must request documentary evidence that they are not in a situation of exclusion.] 

Evidence of financial, economic, technical and professional capacity according to the selection criteria specified in subsection 12.2 above will be requested unless satisfactory documents are already included in the tender. 

If the successful tenderer fails to provide this documentary proof or statement within 15 calendar days following notification of award or if the successful tenderer is found to have provided false information, the award will be considered null and void. In this case, the contracting authority may award the tender to the next lowest tenderer or cancel the tender procedure. 

The contracting authority will inform all tenderers simultaneously and individually of the award decision. The tender security of the unsuccessful tenderers will be released once the contract is signed. 

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 

## 26. CONTRACT SIGNING AND PERFORMANCE SECURITY 

26.1 Within 30 days of receipt of the contract already signed by the contracting authority, the selected tenderer must sign and date the contract and return it, with the performance security (if applicable) to the contracting authority. On signing the contract, the successful tenderer will become the contractor and the contract will enter into force. 

26.2 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 invoke 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.
