The <br />backfill was placed between July 12 and July 17, 1989. <br />Compaction tests were taken and recorded, these results are <br />attached. <br />The controlled fill was placed by Febbraro Construction Co. of <br />Trinidad, CO. The project consisted of placement of a corrugated <br />metal pipe outlet structure with three seepage collars. Backfill <br />around the outlet pipe and collars was compacted by using <br />jumping-jack type compactors. Embankment above the outlet pipe <br />was placed in lifts approximately six to eight inches thick and <br />compacted with a vibrating type sheep's foot roller. No major <br />problems were encountered during the project. <br />We hope this has provided you with the required information. <br />Should you have any questions, please feel free to contact [his <br />office. <br />Respectfully submitted, <br />LINCOI~D1~'D~VORE, INC. <br />y ~~ry ~'. >, Frank <br />~ F m~ <br />cc: Lincoln-DeVore, Colorado Springs, CO <br />
