Barry Nelson <br /> <br />Subject: Cost Estimate, Phase I <br />Continental Dam <br />Drilling and Preliminary Stability Analysi:; <br />Hinsdale County, Colorado <br /> <br />Dtar Sir: <br /> <br />As requested by Mr. Bill Paddock, we have obtained a fInn price cost estimate for <br />drilling and testing for the proposed work on Continental Dam from Smith Drilling <br />Company of Grand Junction, Colorado. <br /> <br />Mr. Smith has estimated the drilling costs including mobilization excluding materials <br />at $19,000. This is based on an hourly rate which we believe is more appropriate for this <br />project because of the difficult access and testing. We will use a track mounted drill rig <br />that will be easier to move c.Iown the slopes with minimum construction of access roads. <br />"The following is an estimate of cost for Phase 1. <br /> <br />Drilling (hourly) <br />Geologist <br />Logging and testing 14 days <br />Per Diem <br />Air Fare <br />Stability Analyses <br />Seepage Analyses <br />Report Preparation <br /> <br />$19,000 <br /> <br />Estimated total CO:it: <br /> <br />9,500 <br />1,800 <br />1,000 <br />2,000 <br />3,000 <br />~ <br />$44,300 <br /> <br />The drilling includes 465 to 500 feet of cored hole; 5 holes at specified locations on <br />the dam; each hole will be evaluated for need ba:;cd on the results of the previous borings. <br />Selective intervals will be tested using packer tests and standing or falling head tcsts; <br />approximately four days of testing is included. This cost does not induc.le the cost of a <br />small bulldoler which we should have available to assist moves. If the Santa Maria <br />Reservoir Company could supply cne for the tenn of the project, significant savings co\!1d <br />be realized. <br /> <br />2353 130th Avenue N.E., Suite 200 <br />Bellevue.
