The purpose of this Amendment is to:

1) Revise the Special Contract Requirements (J-pages) as follows:

a) Section 109 to add an asphalt price adjustment provision.

b) Section 401 to allow pay item payment adjustments.

c) Section 401 to correct the asphalt binder requirement.

d) Section 404 to add a minor hot asphalt concrete performance grade requirement.

e) Section 608 to clarify the requirements for reconditioning paved waterways.

2) Revise the Plans to correct structural summary quantities and modify the footer slab reinforcement plan.

Special Contract Requirement changes

1. Add the following to Section 109 of the Special Contract Requirements, page J-9.

109.06 Pricing of Adjustments. Add the following:

ASPHALT CEMENT PRICE ADJUSTMENT PROVISION

GENERAL The Asphalt Cement Price Adjustment Provision provides for a price adjustment in the form of a payment to the Contractor or a rebate to the Government for fluctuations in the cost of asphalt cement used in the performance of applicable construction work. The price adjustment provisions are applicable only to the asphalt cement, as defined in Subsection 702.01, and incorporated in the following eligible contract pay items:

40101 Superpave pavement

The price adjustment provisions are also applicable when the Government adds extra work to the eligible pay items already existing under the Contract.

The provision will remain in effect throughout the duration of the contract. Enactment of the Asphalt Cement Price Adjustment Provision will only be considered when the increase or decrease in the price of asphalt cement as defined herein exceeds 10 percent.

The Asphalt Cement Price Adjustment Provision is intended to reduce but not eliminate the cost effects of price uncertainty to the Contractor and the Government for asphalt cement used in the jalbright Typewritten Text 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 asphalt cement price fluctuations.

PRICE INDEXES The Government will generate a monthly performance price index for asphalt cement using price data obtained from Poten and Partners, Inc. (PPI), which publishes a weekly report (Asphalt Weekly Monitor) on high and low selling prices for states in five regions throughout the United States including the East Coast/Northeast, the Mid-Continent/Midwest, the Gulf Coast/Mid South, the Rocky Mountains and the West Coast/Northwest. Weekly high and low selling price data reported for East Coast/Northeast will be averaged and used to establish a base price index, BPI, for this project and a monthly performance price index, MPPI, for the duration of the contract. These indexes are defined as follows:

BASE PRICE INDEX The base price index, BPI, is the price index determined by the arithmetic average, as specified above, shown in the four weekly publications immediately preceding the bid opening. The BPI will be provided by the Government after contract award. It is as follows:

BASE PRICE INDEX (BPI) FOR ASPHALT CEMENT

PER SHORT TON (TON) (or PER METRIC TON) = $

MONTHLY PERFORMANCE PRICE INDEX The monthly performance price index, MPPI, is the monthly price index at the time of performance of applicable work as determined by the arithmetic average, as specified above, shown in the four weekly publications issued prior to the last Wednesday of the month (i.e. the monthly performance price index during which asphalt cement is used in the performance of applicable construction work).

PRICE ADJUSTMENTS Price adjustments are calculated by the Government for average conditions and 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 ratio MPPI/BPI falls within the range of 0.90 to 1.10, no price adjustment will be made for any asphalt cement used in construction work performed during the relevant month.

Government Rebate – When the ratio MPPI/BPI 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)

Contractor Payment – When the ratio MPPI/BPI 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)

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 asphalt cement is used in the performance of applicable construction work.

BPI = Base Price Index that is established immediately preceding the bid opening.

Q = Quantity in tons of asphalt cement for eligible pay items that were used on the project during the progress payment period. The quantity will be calculated using the asphalt content of the approved mix design and the following formula:

Q = Asphalt Concrete Pavement tons placed x (% Asphalt/100)

PRICE ADJUSTMENT COMPENSATION Monthly adjustments will be accrued. The final price adjustment will be paid, or rebated, after completion of all work for eligible pay items. The Contractor may request in writing 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.

No price adjustments will be made for work performed beyond the Government-approved Contract completion date.

The maximum allowable monthly and final price adjustment to the Contractor or rebate to the Government is limited to a (MPPI/BPI) ratio of 1.6 and 0.4, respectively.

2. Delete Subsection 401.01 of the Special Contract Requirements, Page J-17, and substitute the following:

401.01. Add the following:

5. Add the following to Section 608 of the Special Contract Requirements, page J-30.

608.01 Add the following:
