<br />Financial Reoortina Unit Rates
<br />Tenmile TSF
<br />Assumptions:
<br />(1) Trucks, Loader, and Dozers in 2000 Reclamation Cost Estimate are reasonable (only change to 2000 cost estimate are equipment 6labor rates)
<br />(2) Soil Replacement Thickness is 36" over 25% of (wet) cover, area to 12" over 75% of (dry) cover area. Swell Factor = 1.215 from 2000 Cost Estimate
<br />(3) Revegetation is covered elsewhere
<br />Tasks:
<br />Grade Ten mile Barge Complex Area A7. From previous state based estimate
<br />Grade Tenmile Tunnel Complex Area AB (See Tenmil e Tunnel bulkhead 8 seal). From previous state based estimate
