NE <br />FEASIBILITY ESTIMATE <br /> <br />TIME 14:22:01 <br /> <br />TITLE PAGE 2 <br /> <br />This alternative consists of excavating a 10' wide pilot channel with <br />2H to IV sideslopes. The pilot channel will have riprap inlet and outlet <br />structures, and a grade control structure all of which are sized for <br />the ultimate channel width of 200'. The excess material generated by <br />clearing and grubbing will be placed in rows just beyound the limits of <br />disturbance. The excess material generated by the pilot channel will be <br />placed in a berm along the east side of the channel. Cleared and Grubbed <br />material will be left on site. <br /> <br />The project was designed by Greenhorne & D'Mara, Inc. and quantities for the <br />estimate were completed by the same A & E firm. <br /> <br />Contingencies for the project are set at 20\. Planning, Engineering, & <br />Design were assumed to be 5% based on review comment number 60 from the Corps. <br />The CorpS's review comments are included in the supporting data for this <br />estimate provided under separate cover. Construction Management was assumed <br />to be 6% based on the project template sent by the Corps. <br /> <br />EQUIP ID: MR0054 <br /> <br />Currency in DOLLARS <br /> <br />UPB ID: MRON93 <br /> <br />CREW ID: MRONAT <br />
