Abnormally Low Tender Explanation in Turkey: Evidence and Checklist

Read the clarification request before calculating

An abnormally low tender explanation connects your offered price to a verifiable cost calculation. This guide concerns procurement in Turkey; it is not a substitute for the tender documents or current rules. Start with the authority’s request, not a generic file from another tender. Record the deadline, submission channel and the precise items for which an explanation is required. Do not assume that every line of the bid must be explained. Check the applicable Turkish rules and the notification before relying on any minimum response period.

Build an evidence trail for each cost component

For each requested component, identify the quantity, unit, rate, evidence and price period. A public unit-price schedule, a third-party quotation and your own production records are different evidence routes. Record the issuing body, item number and relevant period for public prices. Whether separate analyses or supporting attachments are required depends on the applicable provision and the way that price is used; there is no blanket exemption. For third-party quotations, check the required professional certification and supporting records. For own production, retain the accounting and cost evidence that supports the calculation.

Reconcile quantities, unit rates, labour and transport

The quantity take-off, unit-rate analysis, transport calculation and labour cost must describe the same scope. Confirm that square metres, cubic metres, tonnes and hours have not been mixed. Keep the source and period visible on every rate. Check haulage distances, formula coefficients and any separately priced transport. Labour calculations must match the relevant requirements and the period used in the tender. Finally reconcile line totals, rounding and the grand total with the offer. Do not invent a public item or price for work that has no supported equivalent.

Avoid common rejection risks

Late preparation leaves little time to verify signatures, supporting records or electronic submission. Other recurring risks are mixed price periods without explanation, quotations without the required supporting documents, responding to items outside the requested scope, and totals that disagree between the analysis and summary. A longer file does not fix a missing evidence link. Keep drawing revisions and the origin of each quantity traceable so that a reviewer can follow the calculation.

Review the complete submission before delivery

Use a final checklist covering scope, quantities, units, sources, periods, calculations and attachments. Assign one person to reconcile the final file with the clarification request. The downloadable checklist below is in Turkish. Keep a copy of the submitted version and the submission receipt. The Excel template supports calculations but does not establish that a quotation or analysis is legally acceptable.

If the explanation is rejected

Read the reasons in the authority’s decision and identify whether the problem concerns evidence, methodology or scope. Complaint and appeal procedures have their own conditions and deadlines. Verify the current rules through the Turkish Public Procurement Authority before taking action; no outcome or acceptance is guaranteed.

Useful information: sources and price periods

Record the issuing body, item code and exact rate period (YYYY-MM). This guide publishes no current monthly rates. Check the original schedule before using a price; verify whether profit and overhead are already included. The workbook adds 25% only for Analiz lines; this is not a universal legal rate.
