In the subsection Task #01, I believe you should use just the drill operating <br />hours of 61.88 hrs to base the 25% dozer support time. 25% of 61.88 hours is <br />15.47 hrs at 197.10 $/hr. The dozer is only needed to prepare an existing bench <br />for drilling. <br />2. In the subsection Task#09, I don't believe a water truck is needed or would even <br />be effective in the task of controlling dust pre or prior to the motor grader <br />scarifying the ground for topsoil lay down. Water would not penetrate the pre- <br />scarified compacted earth enough to control dust and the post scarified ground <br />would be too rough to drive over and would dry out anyway if sidebar sprayers <br />were used. I recommend that the cost of the support water truck be removed <br />from subsection Task #09 <br />3. In subsection Task #030, the acreage has changes and so has the hours and <br />thus the cost. I agree with your methodology. Just be sure to check that the <br />hours from the real Task #30 follows through. <br />4. Subsection Task #031, Same comment as Task #030 above, the acreage have <br />changed. <br />F:\Eng\DATA\WP\revisions\TR54.wpd Pag03 Of t5 <br />
