The National Council shall set the time limits for receipt of tenders, taking into account the complexity of the contract and the time needed by economic operators to prepare their tenders.
The minimum time limit for receipt of tenders may not be less than thirty-five days from the date on which the contract notice is sent in the case of open invitations to tender.
In the case of restricted invitations to tender and the procedure with negotiation, the time limit for receipt of tenders may be set by mutual agreement with the selected candidates, provided that this date is the same for all of them. In the absence of agreement, the National Council shall set a deadline which may not be less than ten days from the date of dispatch of the invitation to tender.
The deadline for receipt of tenders shall be extended in the following cases:
1° Where additional information, necessary for the preparation of the tender and requested in good time by the economic operator, is not provided within the deadline set;
2° Where significant amendments are made to the consultation documents.
The length of the extension is proportionate to the importance of the information requested or the changes made.
