Data on Rate of Change Compared to the Same Period of the Previous Year for Price Indices Used in Calculating the K Value

Data on the rate of change compared to the same period of the previous year for the price index used in calculating the Escalation Factor (K). The index figure is used to measure the change in the cost of work at the time the construction contractor opens the bid envelope, compared with the period of work orders in each installment. Important conditions are as follows: (1) The "K value" may be used only when the contractor receives work from government agencies, state enterprises, units under the Local Administration Act, and other units that have the status of local administrative agencies by law. (2) In the hiring contract, the parties must clearly state in the contract that it is a price-adjustable contract in the bidding for construction hiring.
