938.01 DESCRIPTION. The intent of this provision is to insure adequate and fair compensation for
unpredictable and fluctuating costs which, from time to time, occur in the prices of Liquid Asphalt and Diesel Fuel. The price adjustment provisions are made part of the Contract to assure more realistic bidding and encourage competition. 938.02 DEFINITIONS. 938.02.1 Base Price. The base price is the unit price of the material (FOB Terminal), as determined by the Department, just prior to the first date that the NOTICE TO CONTRACTORS is advertised in the public press. 938.02.2 Period Price. The period price is the unit price of the material (FOB Terminal), as determined by the Department, for any one mont h period following the NOTICE TO PROCEED during which the price varies from the base price. 938.03 PRICE ADJUSTMENT. Price adjustment will be determined by the difference between the Period Price and the Base Price. Price adjustments will be made at the end of each month during which a); work was accomplished on the project and b); prices varied. Price adjustments for work performed after the contract completion date, as may be modified by approved time extension(s), will be t he lesser amount calculated from the following two algorithms (a & b); whereas credit due the Department will be greater of the two calculations.
a.The price adjustment calculated using the actual monthly Period Prices in effect at the time of the construction.
b.The price adjustment calculated using the monthly Period Prices in effect during a period determined by setting the last day of relevant work to the contract completion date as may have been modified by approved time extensions. Price adjustments due the contractor will be m ade in accordance with an approved Contract Addendum. Credit due the Department will be proc essed by deducting monies from progress payments or by other means if there are insufficient progress payments remaining.
938.03.1 Liquid Asphalt Cement. The asphalt content will be the optimum amount used in every
ton of bituminous concrete mixture, as determined by the Department's Materials Engineer, using the method for determination of optimum asphalt cement content as set forth in SECTION M.03 of these Specifications. The Price Adjustment will be determined by multiplying the total weight of liquid asphalt, in tons, by the difference between the base price and period price. The Base Price of Liquid Asphalt Cement is set forth in Special Provision Code 938.1000 . 9−83938.03.2 Diesel Fuel. The fuel for operating the plant, and the fuel for hauling and placing bituminous concrete, will equal the total number of tons of bituminous concrete placed during the month in question times a fuel adjustment factor of 2.5 gallons of fuel per ton of bituminous concrete. Tonnage of bituminous concrete placed during the month in question will equal the sum of the weights indicated on the Daily Automated Recordation printout slips provided at the plant. The Price Adjustment will be determined by multiplying the total volume of fuel, in gallons, by the difference between the base price and the period price. No price adjustment will be made unless the amount of the adjustment, plus or minus, exceeds $250.00 for the month. The Base Price of Diesel Fuel is set forth in Special Provision Code 938.1000 .
