Data on Rate of Change Compared to the Previous Month for the Price Index Used in Calculating the K Value

Data on the rate of change compared to the previous month for the price index used to calculate the Escalation Factor (K).

(2) In the hiring contract, the parties must clearly specify in the contract that it is a price-adjustable contract for construction bidding.
