6-369SECTION 690 – COMMODITY PRICE ADJUSTMENTS

690.01DESCRIPTION . This specification contains price adjustment provisions for commodities used by

the Contractor during construction. These price adjustment provisions will provide for either additional compensation to the Contractor, or a payment to the Agency, based upon changes in the retail price of a commodity between the time of bidding and the time when the work was performed.

690.02GENERAL CONDITIONS

may cause the Agency to decrease the quantities of the pay items subject to adjustment under these provisions. Provisions providing for decreased quantities and item cancellation in this paragraph are separate and take precedence, notwithstanding any other provisions of the Contract.

be justification for an extension of time under Subsection 108.11 .

estimated price adjustments throughout the duration of the Contract, reconciliation of those estimated adjustments will be made upon the determination of actual final quantities. Final adjustments to the total final quantity will be made by prorating those estimated adjustments over the applicable adjustment periods previously paid. Reconciliation of any price adjustments will only be performed in those instances where the actual final quantity differs by more than 5% from the total estimated quantity. Payments owed to either the Contractor or the A gency will not be subject to any applicable interest claims.

established by the Agency. This price will be specified in the Contract and will be the basis from which commodity price adjustments for pay items included in the original awarded Contract are computed, including pay items where the total quantity is later increased by change order. For pay items added by change order, the index price will be the posted price at the time that the Contractor and the Agency agree to the uni t prices of the pay items to be added. This index price will be specified in the change order and will be the basis from which commodity price adjustments for pay items added in that change order are computed.

690 6-370 (g) Posted Price . For the duration of the Con tract, the posted price for the commodity will be established monthly by the Agency. The posted price will be established in the same manner as the index price and may be found on the Agency ’s website. The posted price used to calculate the adjustment will be the price for the month in which the work was performed.

690.03ASPHALT PRICE ADJUSTMENT

including that incorporated under Special Specification pay items or pay items added by change order, will be subject to adjustment under this specification.

quantity of asphalt from asphalt binder (Q AAB) will be the cumulative amount of virgin asphalt binder for each applicable item as reported on the batch or load ticket.

The quantity of asphalt from asphalt binder (Q AAB) will be calculated using the following equation : 𝑄𝐴𝐴𝐵=𝑄𝑀×𝐹𝐴𝐵 where: QAAB = Quantity of asphalt from asphalt binder (tons) QM = Quantity of mix (tons) FAB = Asphalt binder factor The asphalt binder factor will be the percentage of virgin asphalt binder incorporated into the mixture, expressed as a decimal. In the event of multiple asphalt binder contents, the accepted quantity of mix at each asphalt binder content will be determined, and the total quantity of asphalt used will be calculated accordingly. The accumulated asphalt binder total reported by the plant automation may be checked and verified by Agency personnel for each mix.

690 6-371 b. Asphalt from Emulsified Asphalt . The quantity of asphalt from emulsified asphalt

𝑄𝐴𝐸𝐴=0.05×𝑄𝐸𝐴×𝐹𝐴𝐶 where: QAEA = Quantity of asphalt from emulsified asphalt (tons) QEA = Quantity of emulsified asphalt (hundredweight) FAC = Asphalt content factor The quantity of emulsified asphalt will be determined in accordance with the method of measurement for the specification under which it was placed. The asphalt content factor will be the residual asphalt content percentage of the emulsified asphalt, expressed as a decimal and determined as follows :

required by the specification under which the emulsified asphalt was placed.

asphalt cont ent factor will be the minimum residual asphalt content required by Subsection 702.02 for the grade of emulsified asphalt used.

the emulsion type used in the work is not covered by Subsection 702.02 , the asphalt content factor will be the average residual asphalt content as determined from Agency test results.

calculated using the following equation: 𝑃𝐴𝐴=(𝑄𝐴𝐴𝐵+𝑄𝐴𝐸𝐴)×(𝑃𝑃𝐴−𝐼𝑃𝐴) where: PAA = Price Adjustment, Asphalt (dollars) QAB = Quantity of asphalt from asphalt binder for the month (tons)

PPA = Posted price of asphalt for the month the work was performed (dollars/ton) IPA = Index price of asphalt cement (dollars/ton)

690.04FUEL PRICE ADJUSTMENT

the Contractor is diesel fuel. Fuel price adjustment will only be computed for a pay item if all of the following criteria are met:

adjustment in the Special Provisions or a change order. No other pay items will be subject to adjustment .

690 6-373 (2) The total Contract quantity for a given work category , being the total quantity for all eligible pay items in the work category across all projects in the Contract , equals or exceeds the threshold quantity specified in Table 690.04A . For determining which items are subject to fuel price adjustment for a given month, the total Contract quantity will be the quantity, as adjusted by change order, on the last calendar day of the month. Pay items belonging to a work category which ha d a total Contract quantity that was less than the threshold quantity will become subject to fuel price adjustment if additional pay items are added, or the quantities of existing pay items are increased, by change order such that the total quantity for the work category equals or exceeds the threshold quantity. However, only work performed during or after the month in which the change order was processed will be subject to fuel price adjustment. Work that was already performed in prior months will not be subject to retroactive fuel price adjustment. Pay items belonging to a work category which ha d a total Contract quantity that was greater than the threshold quantity will no longer be subject to fuel price adjustment if pay items are removed, or the quantities of existing pay items are decreased, by ch ange order such that the total quantity for the work category no longer equals or exceeds the threshold quantity. However, only work performed during or after the month in which the change order was processed will not be subject to fuel price adjustment. W ork that was already performed in prior months will still be subject to fuel price adjustment.

calculated using the following equation: 𝑅=𝑃𝑃𝐹 𝐼𝑃𝐹 where: R = Ratio of the posted price to the index price PPF = Posted price of diesel fuel for the month the work was performed (dollars/gallon) IPF = Index price of diesel fuel (dollars/gallon)

690 6-374 (2) Fuel Price Adjustment Quantity . The quantity of fuel price adjustment will be computed using the appropriate equation below. If multiple items are eligible for fuel price adjustment, the fuel price adjustment for each individual item will be calculated and the resulting values summed to gene rate one fuel price adjustment for the month. For R < 0.95 𝑃𝐴𝐹=𝐹𝐹𝑈×𝑄×[𝑃𝑃𝐹−(0.95×𝐼𝑃𝐹)]

For 0.95 ≤ R ≤ 1.05 𝑃𝐴𝐹=0

For R > 1.05 𝑃𝐴𝐹=𝐹𝐹𝑈×𝑄×[𝑃𝑃𝐹−(1.05×𝐼𝑃𝐹)] where: R = Ratio of the posted price to the index price PAF = Price Adjustment, Fuel (dollars) FFU = Fuel usage factor (gallons/unit) Q = Quantity of the item placed in the month (varying units) PPF = Posted price of diesel fuel for the month the work was performed (dollars/gallon) IPF = Index price of diesel fuel (dollars/gallon)
