The time-limit for receipt of tenders is indicated under Heading IV.2.2 of the contract notice where local time shall be understood as local time at the contracting authority's location (the location indicated under Heading I.1 of the contract notice). 

A tender received after the time-limit for receipt of tenders will be rejected. The submission receipt provided by e-Submission with the official date and time of receipt of the submission (timestamp) constitutes proof of compliance with the time-limit for receipt of tenders$^{4}$. 

Tenderers must ensure that their submitted tenders contain all the information and documents required by the contracting authority at the time of submission as set out in the procurement documents. 

The following documents shall be dated and signed, either by hand or by applying a qualified or an advanced electronic signature based on a qualified certificate, by an authorised representative of the signatory: 

 Declaration(s) on Honour on exclusion and selection criteria (template available in the tender specifications). 

 The submission report (a document generated by e-Submission and listing all the documents included in the tender, to be signed by the tenderer or the group leader in case of a joint tender). 

When the Declaration(s) on Honour and/or the submission report are signed by hand, a scanned copy must be attached to the tender in e-Submission. The hand-signed originals must be sent by letter to the contracting authority's postal address specified under Heading I.1 of the contract notice at the latest on the first working day following the electronic submission of the tender. The envelope, clearly mentioning the reference to the call for tenders and the e- Submission ID of the tender, must be marked as "CALL FOR TENDERS – NOT TO BE OPENED BY THE INTERNAL MAIL DEPARTMENT". Only the originals of the Declaration(s) on Honour and the submission report are to be sent by letter, not other documents. 

After submitting a tender, but before the deadline for receipt of tenders, a tenderer may definitively withdraw its tender$^{5}$, or withdraw it and replace it with a new one$^{6}$. A withdrawal receipt will be provided by e-Submission as proof of withdrawal. 

All costs incurred for the preparation and submission of tenders are to be borne by the tenderers and will not be reimbursed.
