Section 2120. Fuel Adjustment

Fuel Adjustment (FA) is an adjustment to monthly progress payments for cost changes in diesel fuel used on specific items of work identified.

2120.02 price index Definition.

A. A Current Price Index (CPI) in dollars per gallon (liter) will be established by the Department of Transportation for each month. The CPI will be the price of No. 2 High Sulfur Diesel, as reported by the Oil Price Information Service, using the first weekday of the month and the average of all prices reported for Des Moines. This information will be available on the Departments’ website.

B. The Base Price Index (BPI) for each contract will be the CPI in effect during the month previous to the month of letting of that contract.

A. Applied as the work is done, according to this specification when indicated in the contract documents.

B. Fuel adjustment using a fuel adjustment factor
(FUF) of 0.20 gallon per cubic yard (1.0 L/m^{3}) will be applied to:

**1.** Selected Backfill (including Stockpile)

**2.** Class 10 (Roadway & Borrow, Unsuitable, Waste,
Stockpile, and Channel)

**3.** Class 12 (Roadway & Borrow, Channel, and
Waste)

**4.** Class 13 (Roadway & Borrow, Channel, and
Waste)

** **

**5.** Topsoil, Furnish and Spread

**6.** Topsoil, Spread

**7.** Topsoil, Strip, Salvage, and Spread

**8.** Topsoil, Strip and Stockpile

** **

**C.** Fuel
adjustment using a FUF factor of 0.27 gallon per cubic yard (1.3 L/m^{3})
will be applied to Embankment-in-Place (non-dredge material).

D. Fuel adjustment will also be applied to Embankment-In-Place (dredge material). The fuel usage will be based on billed gallons (liters) of fuel used.

2120.04 Method of Measurement.

A. Provide the Engineer with a monthly spreadsheet (the Engineer will provide the format) with quantities, and the fuel adjustment for the month (even if there will be no adjustment).

B. If the contract quantity for an item is in tons (megagrams), convert the quantity to cubic yards (cubic meters) using an appropriate conversion factor the Engineer approves. The total quantity of cubic yards (cubic meters) for each month (Y) is the sum of these quantities.

C. If the work is not completed within the contract period or authorized extensions thereof, the CPI to be used for work done after the contract period is to be the CPI that applied during the last working day within the contract period, including authorized extensions.

**D.** A fuel
adjustment factor that accounts for the estimated amount of fuel used per cubic
yard (cubic meter) of work covered by this specification will be applied to
items of work covered in Article 2120.03, B or
2120.03, C.

**E.** A fuel
adjustment will be made for items of work covered in this specification when
the CPI for the month the work is performed is more than $0.15 per gallon ($0.04
per liter) different than the BPI established at the beginning of the project.

**1.** For items of work covered in
Article 2120.03, B or
2120.03, C:

**a.** If the
CPI is greater than the BPI plus $0.15, then the fuel adjustment will be
positive which warrants additional payment to the Contractor. The following
formula will be used to calculate the additional payment:

(English) FA = FUF(CPI - (BPI + 0.15))Y

(Metric) FA = FUF(CPI - (BPI + 0.04))Y

**b.** If the
CPI is less than the BPI minus $0.15, then the fuel adjustment will be negative
and a credit will be due to the contracting authority. The following formula
will be used to calculate the credit:

(English) FA = FUF(CPI - (BPI - 0.15))Y

(Metric) FA = FUF(CPI - (BPI - 0.04))Y

** **

**2.** For the item of work covered in Article 2120.03,
D:

**a.** If the
CPI is greater than the BPI plus $0.15, then the fuel adjustment will be
positive which warrants additional payment to the Contractor. The following
formula will be used to calculate the additional payment:

(English) FA = (CPI - (BPI + 0.15)) x

(billed gallons of fuel used per month)

(Metric) FA = (CPI - (BPI + 0.04)) x

(billed liters of fuel used per month)

**b.** If the
CPI is less than the BPI minus $0.15, then the fuel adjustment will be negative
and a credit will be due to the contracting authority. The following formula
will be used to calculate the credit:

(English) FA = (CPI - (BPI - 0.15)) x

(billed gallons of fuel used per month)

(Metric) FA = (CPI - (BPI - 0.04)) x

(billed liters of fuel used per month)

A. Payment will be the Fuel Adjustment (FA) for each month, subject to the deduction for partial payments described in Article 1109.05. Should the Fuel Adjustment (FA) be negative, an equal amount will be deducted on payments made to the Contractor from sums otherwise due. This payment or deduction will be made by change order.

B. On completion of the work of the contract:

1. For all items covered in Article 2120.03, B or 2120.03, C, the sum of the total quantities (Y) for each monthly period will be adjusted, if necessary, to agree with the final quantities to be paid.

2. For the item covered in Article 2120.03, D, the sum of the total quantities for billed gallons (liters) of fuel used for each monthly period will be adjusted, if necessary, to agree with the final quantities to be paid. This adjustment will be made by either:

· Subtracting the proper quantity from the last adjustment made, or

· Adding the proper quantity and computing the adjustment on the basis of the CPI in effect on the last working day any of this work was done.

C. On completion of the work of the contract, the monthly fuel adjustment will be revised by pro-rating any variance from the plan quantity.

D. Payment or deduction is full compensation for all fluctuations in fuel prices during the time the contract work is being done.
