Data on the rate of change compared to the same month of the previous year for the Price Index for the preparation of the K value

Data on the rate of change compared to the same month of the previous year for the Price Index used to calculate the Escalation Factor (K). The index figures measure the change in the cost of work at the time the construction contractor opens the bid, compared to the time of ordering in each installment, subject to the following important conditions: (1) The "K factor" may be used only when the contractor receives work from government agencies, state enterprises, units under the Local Administration Act, and other units with legal status as local administrative agencies. (2) In the hiring contract, the parties must clearly state in the contract that it is a price-adjustable contract for the construction tender.
