Any business may ask to participate in a restricted procedure, but only those who are pre-selected will be invited to submit a tender. The time limit to request participation is 37 days from the publication of the contract notice. The public authority then selects at least 5 candidates with the required capabilities, who then have 40 days to submit a tender from the date when the invitation was sent. This time limit can be reduced to 36 days, if a prior information notice has been published.
Note: In urgent cases the public authority may set a time limit of 15 days to receive participation requests (if the notice is sent electronically, this can be reduced to 10 days) and 10 days for the submission of the tenders.
