If a time extension is requested for unusually severe weather, submit a time impact analysis according to Subsection 108.04(b) and include supporting historical weather data according to Subsections 155.04A and 155.04B. The following criteria will be used for determining a time extension for unusually severe weather:

(1) Time adjustment for rain delays. If the net number of actual workdays lost to rain is less than the total lost days for the month in question, then no time adjustment will be made. If the net number of actual workdays lost to rain is more than the total lost days for the month in question, then a time extension may be granted.

(2) Time adjustment for other weather delays. If a time extension is requested for other unusually severe weather conditions (such as snow, extreme cold or heat, or high winds), follow the same calculation, submittal, and criteria procedures as outlined for rain delays.

Add the following after Subsection 109.06:

109.06A Fuel Price Adjustment Provision. This provision provides for a price adjustment in the form of payment to the Contractor or a rebate to the Government for fluctuations in the cost of diesel fuel consumed in the performance of applicable construction work.

This price adjustment provision is intended to reduce but not eliminate the cost effects of price uncertainty to the Contractor and the Government for diesel fuel consumed in the construction of this contract. It provides for sharing by the Government in a portion of the Contractor’s risk, which could result from unusual price fluctuations. The provision is not intended to compensate the Contractor for normal day-to-day fluctuations and seasonal changes or to serve as a guarantee of full compensation for diesel fuel price fluctuations.

J-6

This price adjustment provision is applicable only to contract items listed as eligible pay items in Table 109-2. This price adjustment provision is also applicable to eligible pay items when the Government adds extra work to the contract.

The Fuel Price Adjustment Provision will remain in effect throughout the duration of the contract. Enactment of this provision will only be considered when the increase or decrease in the price of diesel fuel as defined herein exceeds 10 percent.

No price adjustments will be made for work performed beyond the contract completion date.

(a) Price indexes. The Government will determine price indexes for diesel fuel using price data obtained from the Oil Price Information Service (OPIS), which publishes a weekly newsletter on the distillate wholesale rack prices for major cities throughout the United States. The OPIS 5-day newsletter average rack price of Gross Ultra Low Sulfur, No. 2 Diesel Fuel reported for Little Rock, AR will be averaged and used to establish a base price index (BPI) and a monthly performance price index (MPPI). These diesel fuel indexes are defined as follows:

• Base price index (BPI). The BPI is the price index determined by arithmetic average as specified above, shown in the four weekly publications immediately preceding the contract award. It is as follows:

BASE PRICE INDEX (BPI) FOR GROSS ULTRA LOW SULFUR, NO. 2 DIESEL

FUEL

PER GALLON = $ See Note (1) .

Note (1): BPI is calculated by the Government and inserted here immediately before contract award.

• Monthly performance price index (MPPI). The MPPI is the monthly price index at the time of performance of applicable work as determined by arithmetic average as specified above, shown in the four weekly publications issued before the last Wednesday of the month in which the work was performed.

The diesel fuel BPI and MPPI will be posted at https://highways.dot.gov/federal-lands/business/escalation-factors.

(b) Price adjustments. Price adjustments calculated by the Government are not intended to reflect the Contractor’s actual purchase price. The ratio of the monthly performance price index and the base price index (MPPI/BPI) is calculated and used to determine price adjustments for eligible pay items as follows:

• No price adjustment. When the MPPI/BPI ratio falls within the range of 0.90 to 1.10, no price adjustment will be made for any diesel fuel consumed in construction work performed during the relevant month.

https://highways.dot.gov/federal-lands/business/escalation-factors

J-7

• Government rebate. When the MPPI/BPI ratio is calculated to be less than 0.90, the Government is due a rebate determined in accordance with the following formula:

Government rebate = [0.90 – (MPPI/BPI)] (BPI) (Q) (FUF)

• Contractor payment. When the MPPI/BPI ratio is calculated to be greater than 1.10, the Contractor is due additional payment determined in accordance with the following formula:

Contractor payment = [(MPPI/BPI) – 1.10] (BPI) (Q) (FUF)

The following definitions are applicable to both the Government rebate and the Contractor payment formulas:

MPPI = Monthly Performance Price Index for the month during which diesel fuel is consumed in the performance of applicable construction work.

BPI = Base Price Index that is established immediately preceding the contract award.

Q = Quantity of work on the project during the progress payment period for eligible pay items shown in Table 109-2.

FUF = Fuel Usage Factor shown in Table 109-2 applicable to No. 2 diesel fuel.

Table 109-2

Eligible Pay Items for Price Adjustments and Associated Fuel Usage Factors Eligible Pay Items Fuel Usage Factor

Earthwork Section 204 – Excavation and Embankment 20420 Embankment Construction

0.30 gallons per cubic yard

Aggregate and Base Courses Section 301 – Untreated Aggregate Courses 30101 Aggregate Base (Limestone) 30110 Aggregate Surface Course (Limestone)

0.70 gallons per ton

(c) Price adjustment compensation. Monthly adjustments will be accrued. The final price adjustment will be paid, or rebated, after completion of all work for each eligible pay item.

The Contractor may request a partial price adjustment payment once every 12 months, or when the unpaid accrued increase exceeds $10,000. The Government will take a rebate when the deductive accrual exceeds $10,000.

The maximum allowable monthly and final price adjustment to the Contractor or rebate to the Government for fluctuations in the cost of diesel fuel is limited to a MPPI/BPI ratio of 1.6 and 0.4, respectively.

Add the average number of workdays lost to the standard deviation. The total number of lost days (average workdays lost plus 1 standard deviation, rounded to whole days) will be considered normal for each month.

At the option of the Contractor, provide the necessary instrumentation to support weather-related impacts to the project if using the nearest weather station is impractical. If onsite weather instrumentation is not provided, use the nearest weather station.

Provide a weekly summary of the weather data gathered to the CO.

155.04B Unusually Severe Weather. If requesting a time extension due to unusually severe weather, calculate the number of actual workdays lost by totaling the actual rain days plus the actual drying days occurring in the month in question. From this total, deduct any workdays meeting any one of the following conditions:

(a) The rain day or drying day occurred on a non-work weekday such as a holiday.

(b) The rainfall occurred at a time when no weather dependent work was in progress or occurred during planned or unplanned shutdowns due to other circumstances such as equipment failure, strikes, material supplies, delays, etc.

(c) The Contractor was still working or able to work on weather dependent activities to the extent that less than 50 percent of the workday was lost due to weather.
