From page 112... ... 112 A.1 Purpose and Scope The purpose of this document is to set forth revised fuel usage factors and procedures for development and use of fuel price adjustment contract provisions. These provisions minimize the cost effects of price uncertainty for fuel used in highway construction. Read the entire page →

From page 116... ... 116 Fuel Usage Factors in Highway and Bridge Construction Fluctuating petroleum prices have led to increases and decreases in the costs of fuel and asphalt products. Rising demand from China and other developing countries drove up prices for steel and other building materials. Read the entire page →
From page 117... ... Recommended practice and Model Specification 117 recommendations are presented. The first is to cut the fuel usage factors for structures approximately in half, from 19 to 9 for cast-in-place structures and from 10 to 5 for pre-cast structures. Read the entire page →

From page 119... ... Recommended practice and Model Specification 119 Based on each estimator's experience and background, they each developed different equipment lists and production rates to accomplish each task. The end result, however, was that the fuel consumption rate for each activity was very consistent for each activity. Read the entire page →
From page 120... ... 120 Fuel Usage Factors in Highway and Bridge Construction The most variable cost of asphalt operations is the haul distance from the plant to the project. In order to minimize this effect on fuel use, we have broken each of the three main asphalt activities (structural, surface, and leveling courses) Read the entire page →
From page 121... ... Recommended practice and Model Specification 121 Miscellaneous Concrete, Concrete Pavement, and Retaining Wall The items within this section are relatively standard and all the estimators calculated similar equipment lists and production rates. Although concrete curb specifications can vary from state to state, the equipment required and production rates are relatively consistent. Read the entire page →

From page 124... ... 124 Fuel Usage Factors in Highway and Bridge Construction fuel use factors for specific items or impose minimum quantities. This is because certain items or smaller quantities result in low levels of fuel use and, as a result, the adjustment would be small in comparison to administrative cost. Read the entire page →
From page 125... ... Recommended practice and Model Specification 125 To calculate the number of gallons per $1,000 of contract value, it was necessary to calculate the historical averages for concrete and steel then multiply the average bid price by the quantities calculated for constructing the average structure. The result is an average contract value of the bridge items. Read the entire page →
