Until further notice. etc. If the midpoint of construction is computed. Fuel price variations will have more effect on items that are equipment oriented such as excavation. local costs should be considered. The overall effect on the typical road construction project is that 30-40% fuel price increases will increase the total cost of construction about 2-5%. These adjustments are mandatory and will be used for all timber sale contracts having specified road construction. small quantity factors should not be applied to individual road costs when the individual USDA Forest Service Northern Region -5- Cost Estimating Guide for Road Construction February 2011 .

FSH 2409.Temporary Road Cost Estimating Cost Estimating for Temporary Roads The decision to construct temporary roads for a timber sale or other activity is based on transportation planning and resource objectives that are documented in a NEPA decision. Temporary roads generally are built for one or two seasons of use for limited traffic. Therefore it is included in the logging costs and not in Table T-1. The costs of seeding include the road bed. and building water bars or cross ditches after the road is no longer needed. Step 3: Using Table T-1. the estimator should use the labor rates and equipment rental rates (for old equipment) contained in this Cost Guide. Step 7: Determine the total cost of drainage structures: Dips: $125 each Culverts: See Table T-2 Step 8: Add the costs determined in Steps 6 & 7. If time and equipment methods are used. Temporary road cost estimates shall be based on the data and procedures contained in the current Cost Guide for road construction. bucking. determine seeding cost per mile by continuing horizontal on the same line used in Steps 1 and 2. Add the appropriate allowance for Mobilization (See Table T-4). In addition to this NFMA requirement. or lease.04c). removal of culverts and ditches. If turnouts or turn-arounds are desired. the timber sale contract requires outsloping. if native seed is required. This item should be included in every temporary road. should be used to develop temporary road costs. Step 2: Using Table T-1. NOTE: seeding costs do not make allowances for native seed. The labor rates need to be adjusted per section entitled Davis-Bacon/Purchaser Wage Rate Adjustments which appear earlier in this publication and have the profit of 6% removed. The National Forest Management Act (NFMA) requires that any temporary road built as part of a timber sale or other permit/lease shall be designed with the goal of reestablishing vegetative cover on the roadway and adjacent disturbed area within ten years after the termination of the contract. The responsibility for the accuracy of temporary road cost estimates rests with the Forest Engineer (FSM 7721. outlines the general procedures for estimating the costs of temporary roads.18.
