based on the size of the job (over 5,200 net dozer hours) and the availability of DIOR <br />dozers. Although the hourly cost for a D l OR dozer is more than that of a D9R dozer, the <br />increase in hourly productivity offsets some of the cost increases. In other words, <br />updating the costs for tasks using a D9R dozer would have increased the liability even <br />more. The following chart illustrates this point. <br />Task D9R Old D9R New D1 OR New <br /> <br />002 $169,852.00 $197,679.00 $162,108.00 <br />009 $34,830.00 $40,536.00 $33,242.00 <br />021 $39,759.00 $46,273.00 $37,947.00 <br />035 $71,603.00 $83,334.00 $69,917.00 <br />081 $1,930.00 $2,246.00 $1,842.00 <br />126 $178.00 $207.00 $172.00 <br /> <br />Total $318,152.00 $370,275.00 $305,228.00 <br />In the table above, for the six tasks shown, the direct costs actually decreased from their <br />original costs. <br />Please let me know if you have any questions regarding the estimate or the cost increases <br />or if you need any additional information. <br />cc: Sandy Brown w/out Attachments
