The contractor continues to face certain operating costs when the equipment is to be on hold. In order to provide fair compensation, custody allowances that appropriately reimburse the cost of owning the equipment to the contractor may be authorized for participation in federal aid. The use of a watch rate is appropriate when the equipment has been made available for forced debts, but for reasons not attributable to the contractor, is stalled. The monitoring rate may be based on the contractor`s actual costs or on data provided in an approved rate guide. In both cases, operating costs should not be included in the rate used. The EFA is calculated by multiplying the average value of the equipment by the cost of many tranches determined by the Minister of Finance in accordance with Public Law 92-41 (85 stat. 97) and by walking this amount over annual hours of use. Based on the above explanatory statement, FHWA found that if the Blue Book is used to calculate equipment rental costs for periods of less than one month, the fairest approach is to use an hourly rate that has been developed by dividing the monthly blue book rental rate by 176. The map at the beginning of each section of the blue book device shows adjustment factors for differences in climate and regional costs. Rate adjustment tables provide the difference between the current prices of new appliances and the price of the equipment during the year of the initial purchase. Previous guidelines have addressed several issues that have not been addressed in previous guidelines.

These include the use of rental prices for preparation facilities, the use of equipment received by a third-party lease agreement and the merits of mobilization costs related to the use of misunderstandings about the development of the Blue Book. In particular, why the monthly rate should be divided by 176 in order to get the hourly rate and how reduced construction times should be addressed. Because leases vary, it may be necessary to determine the specific operating costs of the lease. There may be additional eligible operating costs that are not covered by the contractor`s agreement and should be reimbursed, such as fuel, chewing, field repairs, etc. Depreciation is the loss of value of equipment due to age and consumption.
