This Turkish government communique, published on 3 February 2026, updates the inflation adjustment coefficients applied to contractor certificates (müteahhitlik karneleri) and work completion documents for public tenders in construction, facility, and repair works. It specifies multipliers to be used from 1 January 2026 to revalue old certificates and past work completion values so they can be used in 2026 tender evaluations. The regulation provides a detailed table of coefficients ranging from 54,410,991.030 for pre-1953 documents down to 1.000 for 2026. It revokes the previous 2025 version and maintains the same grouping rules for certificates.

What this law requires
Apply the 2026 evaluation coefficients to contractor certificates (müteahhitlik karneleri) and work completion documents (iş bitirme belgeleri) issued from 1 January 2026 onwards, using the specific multipliers provided in the coefficient table for each year/period.
Multiply the value of contractor certificates dated between 1/3/1981 and 28/2/1982 (inclusive) by the coefficient 766.265,758 when transferring them to new tenders, provided the certificate group classification remains unchanged.
Multiply the value of contractor certificates dated between 1/3/1982 and 31/12/1982 (inclusive) by the coefficient 637.135,791 when transferring them to new tenders, provided the certificate group classification remains unchanged.
Accept and revalue valid contractor certificates (müteahhitlik karneleri) held by contractors participating in tenders by applying the applicable coefficients, while maintaining the same group classification.
Cease application of the 2025 evaluation coefficients (published 31/1/2025 in Official Gazette No. 32799) and replace them with the 2026 coefficients effective from 1 January 2026.
