CONSTRUCTION FUEL COST

698.01Description

This Section shall cover the cost of construction fuel for the equipment necessary for the performance of the required work except for the production of Hot Mix Asphalt (HMA).

698.02Bidding

The bidder shall enter an amount from zero dollars up to the maximum dollar amount shown in the pay item description for fuel on the proposal form. The Contractor signifies that this amount represents a reasonable estimate of the fuel costs isolated from all other costs of completing the required work except for the production of HMA. If a proposal contains an amount greater than the maximum amount shown in the pay item description, the amount bid for Construction Fuel will be assigned a value that is the maximum amount.

698.03Method of Determining Partial Payments and Cost Adjustments

Partial payments for construction fuel will be based on the lump sum bid price for Construction Fuel and the Work Performed ("Work Performed" is defined in Section 101). This component will be calculated as follows. WP ce - WPpe P = CF OC – PBPI 2

Where, P = Amount of Partial Payment. (Dollars) (The total sum of partial payments may be less than or exceed the original contract amount for Construction Fuel.) CF = Lump Sum Contract Amount of "Construction Fuel". (Dollars) WP ce = "Work Performed" (as defined in Article 101.01) at the time of the current estimate or partial payment. (Dollars) WP pe = "Work Performed" (as defined in Article 101.01) at the time of the prior estimate for partial payment. (Dollars) OC = Original Contract Amount. (Dollars) PBPI2 = Original Bid Price for Mobilization, Geometric Controls, and Construction Fuel. (Dollars) The decimal value derived by the term "(WPce – WPpe) / (OC- PBPI2)" rounded to the nearest hundredth will be the decimal amount of the lump sum contract amount for construction fuel. WP is the "Work Performed" (as defined in Article 101.01).

The Department will determine and publish a monthly "Fuel Index" utilizing the average area terminal price reports for regular unleaded gasoline and No. 2 fuel of the "Platts Oilgram Price Report" published during the week in which the first day of the month occurs. The Base Fuel Index (BFI) for the project will be the monthly fuel index published for the month in which the bids were opened for the project. The Current Fuel Index (CFI) for the project will be the monthly fuel index published for the previous month if the estimate is finalized on any day from the 1st through the 10th day of the month. The Current Fuel Index (CFI) for the project will be the monthly fuel index published for the month in which the estimate is finalized if the estimate is finalized on any day between the 11th and the last day of the month. A cost adjustment for construction fuel will be calculated as follows:

TRAFFIC STRIPE 584

CFI CA = P - 1 BFI

Where, CA = Amount of Cost Adjustment (Dollars) P = Amount of Partial Payment Based on Amount of Work Performed (Dollars) CFI = Current Fuel Index (the current month’s CFI is defined above) BFI = Base Fuel Index After the expiration of contract time (plus approved time extensions) two calculations of a potential cost adjustment will be made. The first calculation will be made using the current index (CFI) and the base index (BFI) as noted in the preceding formula. The second calculation will be made using the index during the month that contract time (plus approved time extensions) expired and the base index. The smallest amount of cost adjustment resulting from these two calculations will be made for the current estimate period.

When more than one project is included in one contract, the amount of payment to be made will be based on the "Work Performed", as defined in Section 101, on the entire contract, not on each individual project. Once the amount of partial payment and cost adjustment is determined, this amount will then be prepared for payment on each individual project based on the fraction of the entire contract of which the project is a part.

698.04Basis of Payment

The amount designated for construction fuel, shall be full compensation, after all applicable cost adjustments, for the furnishing of fuel for equipment used on the project, except for the fuel for the production of HMA, and for all materials, equipment, tools, labor, transportation and incidentals necessary for its use. Partial payments for the item of Construction Fuel will be made in accordance with Article

. At the completion of work, the sum of partial payments may exceed or be less than the original

contract lump sum unit price bid. The final quantity may be more or less than 1.0 due to contract overruns or underruns.

If the average of the 3 thickness measurements is 50 % of the target thickness, or less, the sublot shall be removed and replaced without extra compensation. Any portion of the stripe that is determined by the Engineer to be noticeably inconsistent with the overall striping and measures less than 50 % of the target thickness shall be removed and replaced without extra compensation.

Existing traffic stripe (permanent or temporary), markers and adhesive shall be removed by a method that will not damage or disfigure the appearance of pavement surfaces that will be visible at the completion of construction. Burning the old stripe will not be permitted. Hiding the old stripe by covering it with a striping material that is colored to match the appearance of the pavement surface will only be allowed if approved in writing by the Engineer. Covering the old stripe will only be considered for hiding what may remain of the stripe on rough pavement surfaces like Open Graded Friction Course after other methods of removal have failed to adequately remove the old stripe. The Contractor shall propose the type, color and application rate the striping material for review and approval by the Engineer. There will be no extra compensation given for furnishing and applying striping material to hide an existing stripe. Removal of traffic stripe, existing or temporary, will be paid for as a separate item of work.

The Engineer will set the limits of no-passing zones. The Contractor shall provide all other controls required to place the stripe in accordance with the details shown on the plans or as directed by the Engineer. The Contractor shall mark the surfaces prior to the placement of the stripe to insure that the stripe will be installed in the required location. The Contractor may be required to adjust the operation of the striping equipment to cover the width and length of existing stripe.

A tolerance of 1/2 of an inch {13 mm} over or 1/8 of an inch {3 mm} under the required width will be allowed, provided the variation is gradual and does not detract from the general appearance. Segments of broken line may vary up to 1 foot {0.3 m} from the required length. Segments shall have neat edges without mist or drip. Variations from the control guide up to 1 inch {25 mm} will be allowed provided the variation does not increase or decrease at a rate of more than 1/2 of an inch {13 mm} in 20 feet {7.5 m}. Lines that do not meet these tolerances shall be removed and replaced, without additional compensation. Establishment of tolerances does not relieve the Contractor of responsibility to construct as closely as practicable to exact plan dimensions.

The width of the temporary stripe shall not exceed4 inches {100 mm}, but shall have a 1/2 inch {13 mm} under tolerance. Traffic marking tape shall have a nominal 4 inch {100 mm} width. The tolerance for the lengths of the temporary broken stripe sections shall be 1 foot {0.3 m} under and 1 foot {0.3 m} over the length specified in Subitem 701.03(e)5.a. Strict compliance to alignment on underlying surfaces will not be required provided a reasonable straight line of markings is obtained. The tolerances for placement on a wearing surface shall be the same as those for permanent striping.

Permanent or temporary striping placed on a final wearing surface that does not meet the tolerances specified shall be removed and replaced without compensation. This includes areas where the permanent striping does not match the alignment, spacing, etc. of the temporary stripe, leaving the temporary stripe exposed.
