### PROCEDURE FOR ESTIMATING

1. Determine the quantity of work to be performed, classify the type of material and the haul distance.

2. Divide the cubic yardage quantity of work to be performed by the estimated Output in Cubic Yard Per Hour.

3. Round up the hours from step 2 to the next 4 hour increment; therefore, 2.6 Hours becomes 4 Hours;

4 Hours becomes 8 Hours; 35 Hours becomes 36 Hours, etc.

5. Multiply the hours determined in step 3 by the subcontract hourly rate for the selected Crew group. Round off extension of cost to next higher dollar.

6. For moving equipment to the Site, add ($500 - $600) allowance, This covers the cost of loading and delivery to jobsite located within the local area using all weather roads. If equipment is also used in another Activity, prorate these costs.

7. Add the total in dollars to determine the Total Subcontract Cost to perform the work.

### PROCEDURE FOR ESTIMATING

2. Divide the cubic yardage quantity of work to be performed by the estimated Output in Cubic Yard Per Hour.

3. Round up the hours from step 2 to the next 4 hour increment; therefore, 2.6 Hours becomes 4 Hours;

4 Hours becomes 8 Hours; 35 Hours becomes 36 Hours, etc.

5. Multiply the hours determined in step 3 by the subcontract hourly rate for the selected Crew group. Round off extension of cost to next higher dollar.

6. For moving equipment to the Site, add ($500 - $600) allowance, This covers the cost of loading and delivery to jobsite located within the local area using all weather roads. If equipment is also used in another Activity, prorate these costs.

7. Add the total in dollars to determine the Total Subcontract Cost to perform the work.

* CLASS A SITE MATERIAL*, Normally referred to as "Easy Digging", consisting of loose, soft, free running materials. Close lying, which will fill blade, dipper or bucket to capacity, and frequently provide a heaped load. Materials such as dry sand, small gravel, unpacked earth, loam, etc., would fall into this category. Swell Factor of 15%, Load Factor of 0.87. Flat haul, rolling resistance of 5% at Site. Output based on 31 Cubic Yard Scraper Capacity x Load Factor. Fixed Time: 1.3 Minutes

* CLASS B SITE MATERIAL*, Normally referred to as "Medium Digging", consisting of harder materials that are not difficult to dig without assistance such as ripping, blasting, etc. Material breaks up with some bulkiness causing some voids in dipper or bucket. Angle of Repose for this material will increase volume of heaped bucket loads. Packed earth, common earth with some clay, soil with less than 25% rock content would be examples of this category of materials. Swell Factor of 25%, Load Factor of 0.80. Flat haul, rolling resistance of 5% at Site. Output based on 31 Cubic Yard Scraper Capacity x Load Factor. Fixed Time: 1.3 Minutes.
