Frequent Errors in the Abnormally Low Tender Inquiry in Service Procurement Tenders and Ways of Addressing Them

04 September 2025

Public Procurement Law No. 4734 adopts the principle that the tender is to be awarded not to the lowest tender but to the economically most advantageous tender. In service procurements, the economically most advantageous tender is determined by calculating the threshold value from the estimated cost and the tenders submitted, using the EKAP threshold value calculation tools, and by carrying out an abnormally low tender inquiry in respect of tenderers whose tenders fall below the calculated threshold value. Although outside the scope of this article, there are also tenders in which, according to their characteristics, tenderers falling below the threshold value are eliminated directly without an abnormally low tender inquiry.
