Re: Proposal for Survey Work to Support Dredging of Basin 6 <br /> City Project No. 9956 <br /> Page 2 of 3 <br /> section. All work will be performed using GPS survey equipment and we <br /> will provide a boat to perform this work. This information will be used to <br /> generate the existing bottom elevation of Lake Decatur to be input into the <br /> WINOPS system. <br /> • We will locate approximately 37 duck blinds with GPS equipment to <br /> document the existing locations of these blinds. This information will be <br /> used to reset blinds when it is necessary to remove and reset them during <br /> the dredging operations. ', <br /> • At the end of the field operations, we will download this information into <br /> the office server. <br /> Hours: 188 <br /> Cost: $ 15,583 <br /> 3. Office Work <br /> • We will set up state plane coordinates for the horizontal control of the <br /> work in Basin 6. <br /> • We will download, study and evaluate the WINOPS software purchased <br /> with the dredge to insure proper installation of all gathered field <br /> information into WINOPS. <br /> • We will format the survey information into an x,y,z format compatible <br /> with WINOPS software. <br /> • We will develop proposed dredging templates at each cross section for the <br /> �nished bottom of Basin 6 in order for the City to better manage the <br /> volume of dredged material to be removed from Lake Decatur and stored <br /> in the Sedimentation Basin. These templates will be designed to allow for <br /> a reasonable hydraulic grade of the basin. This will provide for an <br /> ef�cient hydraulic shape of the basin, which will minimize the rate of <br /> future sedimentation and provide for a consistent water depth to help <br /> support recreational use. <br /> � We will provide QA/QC of all documents, upload the developed <br /> information into WINOPS and deliver hard copies as well as a CD of all <br /> data to the City of Decatur. <br /> Hours: 99 <br /> Cost: $ 7,455 <br />
