TABLE OF MATERIALS TO BE ADJUSTED AND COST ADJUSTMENT FACTORS FOR DIESEL FUEL USAGE UNITS FACTOR Class 1: Excavation under Sections 207 and 211 Gallons per cubic yard 0.25 Class 2: Crushed aggregate under Sections 307, 311, and 405 Gallons per ton** 0.62 Class 3: Asphalt concrete under Sections 401 and 402 Gallons per ton** 1.06 Class 4: Rigid concrete pavement under Sections 501 and 502 Gallons per cubic yard 0.76 ** Where the pay item for aggregate is in cubic yards, conversion to tons for the purpose of diesel fuel price adjustment will be made on the basis that one cubic yard equals 1.75 tons. Any difference between the checked final quantity and the sum of quantities shown on the mont hly estimates for any item will be adjusted by the following formula: FA = (FCQ ÷ PRQ) x EA Where: FA = Final Adjustment (dollars) for the item which increased or decreased FCQ = Final Checked Quantity of the item which increased or decreased PRQ = Total Quantity of said item previously reported on the most recent estimate EA = Total adjustment in dollars of said item shown on most recent estimate The monthly base price for determining price adjustments for all work performed after the contract completion date, as revised by approved time extensions, will be the monthly base price (Mbp) at the time of the contract completion date (as extended) or at the time the work was performed, whichever is less. The final adjustment will take into consideration any error(s) that may have been made in the computation of any prior monthly adjustments.
109.10 Price Adjustment of Asphalt Binder :
Because of the uncertainty in estimating the cost of petroleum products that will be used during the life of this contract, adjustment in compensation for certain contract items i s provided for as follows: The contract items listed in Table 109.10.1, will be adjusted in accordance with the Division’s indices for asphalt binder. The bidding index (Ib) for asphalt binder will be equal to the placement index as listed on the Contrac t Administrations website for Fuel and Asphalt adjustments for the Wednesday prior to the first day of the month, with the effective date of the index being the first day of the month. If the Wednesday prior to the first day of the month falls on a holida y or the price is otherwise not published for that date, the index will be based on the 91 next earliest date as reported. The placement index (Ip) will be the price in effect on the first of the month in which the specific adjustable material was actually p laced. Both the bidding index (Ib) and the placement index (Ip) will be based on the average of the posted prices of PG 64S-22 asphalt binder per ton/megagram as reported from the following sources on the Wednesday prior to the first day of each calendar month: Marathon Petroleum Company, LLC, Catlettsburg, Kentucky Marathon Petroleum Company, LLC, Floreffe, Pennsylvania Asphalt Materials, Inc., Marietta, Ohio Associated Asphalt, Baltimore, Maryland Associated Asphalt, Martinsburg, West Virginia If one of the sources listed above changes ownership and/or name the posted price for that terminal will continue in use as though the ownership and/or name change had not occurred. If one of the sources used for determining either the bidding index or the pl acement index goes out of business, any future index will be based on the average of the remaining sources. Thus, the bidding index (Ib) could be based on the average of five sources and the placement index (Ip) on the average of four sources or vice -versa. If a source that goes out of business reopens at a later date, the placement index would once again be based on the average of five sources as indicated above. The posted price for each source will be compared to the average of all sources. If the difference between the average and the individual price is greater than 25 % of the average, that individual source will be excluded from the calculation of the average price (Ib) or (Ip) and a new average will be calculated using the remaining sources. Sources chosen for the index are required to report their posting to the Division no later than the Wednesday prior to the first day the month. Failure to report in a timely manner may impact source approval. The portion of the contract unit price which reflects the cost of the specified material will be adjusted for the change in accordance with the following formula: Pa = Q*AC*(Ip – Ib) Where: Pa = Price Adjustment Ip = Price Index at time of placement Ib = Price Index for Bidding AC = Asphalt Content (see Table 109.10.1) Q = ”As Constructed” Quantity The price index for determining price adjustments for all work performed after the contract completion date, as revised by approved time extensions, will be determined as follows: The price index (Ip) shall be for the month in which the contract completion date (as extended) falls, or the price index for the month in which the work was performed, whichever is less. 92 TABLE 109.10.1 -Table of Materials to be Adjusted for Price of Asphalt at the Time of Placement Item Number Asphalt Content (%) Item Number Asphalt Content (%) Item Number Asphalt Content (%) 311006 -001 3.2% 401003 -002 5.0% 402001 -038 7.6% 401001 -020 3.9% 401003 -003 5.0% 402001 -039 7.6% 401001 -021 3.9% 401003 -011 5.0% 402001 -040 6.0% 401001 -022 3.9% 401003 -012 5.0% 402001 -041 6.0% 401001 -023 5.0% 401007 -020 5.7% 402001 -045 5.5% 401001 -024 5.0% 401007 -021 5.7% 402001 -046 5.5% 401001 -025 5.0% 401007 -022 5.7% 402001 -050 5.0% 401001 -040 5.0% 401007 -030 7.6% 402001 -051 5.0% 401001 -041 5.0% 401007 -031 7.6% 410001 -010 3.9% 401001 -042 4.5% 401007 -032 7.6% 410001 -020 5.0% 401001 -043 4.5% 401007 -040 6.0% 410001 -030 5.0% 401001 -050 4.1% 401007 -041 6.0% 410001 -040 4.5% 401001 -051 4.1% 401007 -050 7.6% 410001 -050 4.1% 401002 -020 5.7% 401007 -051 7.6% 410002 -010 5.7% 401002 -021 5.7% 402001 -020 6.2% 410002 -020 7.6% 401002 -022 5.7% 402001 -021 6.2% 410002 -030 4.9% 401002 -023 7.6% 402001 -022 6.2% 410007 -010 6.2% 401002 -024 7.6% 402001 -023 7.6% 410007 -020 7.6% 401002 -025 7.6% 402001 -024 7.6% 410007 -030 4.9% 401002 -035 4.9% 402001 -025 7.6% 410007 -040 7.6% 401002 -036 4.9% 402001 -026 4.9% 410007 -050 6.0% 401002 -037 4.9% 402001 -027 4.9% 410007 -060 5.5% 401003 -001 5.0% 402001 -028 4.9% 410007 -070 5.0% The bidding Indexes (Ib) and the placement indexes (Ip) may be found posted on Contract Administrations website for Fuel and Asphalt Prices at the following link: http://www.transportation.wv.gov/highways/contractadmin/Lettings/Pages/FuelandAsphaltPrices .aspx The bidding index (Ib) for asphalt binder will be listed on the Contract Administrations website for Fuel and Asphalt adjustments for the Wednesday prior to the first day of the month, with the effective date of the index being the first day of the mo nth for which the contract is let.
