The period set forth in the tender documentation for suppliers to raise questions shall be at least one quarter of the period for tendering, and a segment of less than one day shall be counted as one day. For a qualification review of selective tendering procedures, the same shall also apply to the period from the date of publication through the deadline for receipt of documents.An entity may reject the questions raised by suppliers beyond the period set forth in the tender documentation, and shall notify it to the supplier in writing.The number of days counted from the date following the date of the entity's last reply through the deadline for submission of tenders or the deadline for receipt of qualification review documents shall be at least a quarter of the original time-limit for tendering, and a segment of less than one day shall be counted as one day. Where the aforementioned number of days is insufficient, the entity shall make up for the lacking days by extending the time-limit for tendering.
