Inca Street DAILY REPORT NO. 6 SHEET 1 of 2 <br /> Englewood, Colorado 80110 SUBJECT: CONSTRUCTION OBSERVATION REPORT <br /> Eagle Park Reservoir Dam No. 4, Outlet Works Cyprus Climax <br /> ATTN: Mr. Douglas Seely, P.E. Metals, Eagle County, Colorado <br /> WEATHER CONDITIONS (am) (pm) Sunny, windy, temp estimated in 60°s <br /> CONTRACTORS EQUIPMENT 1 CAT CP-433B compactor, 1 Excavator, 1 Front End loader <br /> CONSTRUCTION OBSERVATION AND COMMUNICATION: We visited the site to evaluate the subgrade in the base of the breach excavation prior to resuming fill placement <br /> after the winter shutdown. At the time of our arrival on-site, the surface material disturbed by the winter exposure had already been removed and covered with approximately 1 <br /> foot of new fill, according to Mr. Kenny Sheesley of ASI RCC. Pits were excavated at 4 locations, 2 on each side of the outlet conduit, to visually assess the original <br /> embankment fill below the level disturbed on this project. Moisture-density tests were also performed with a nuclear densometer in the original embankment fill to further <br /> document the conditions. The observations and test results indicated adequate fill conditions below the elevation of the fill surface (approximate Elevation 10,683 112 to 10,684 <br /> feet) this date except for approximately the west half of the north side along the conduit. We understand that wet conditions have been observed in that area over approximately <br /> the past week, and that the embankment fill may have been disturbed in this area. A trench was excavated to approximate Elevation 82' in this area, sloped to the west, and <br /> seepage was observed in the trench. Mr. Sheesley was advised that any embankment fill that has been disturbed in this area should be removed without further disturbance to fill <br /> beneath it. If the seepage stops, the area of removal can be filled with compacted backfill. Several alternatives were discussed for resuming backfilling if the seepage persisted. <br /> (See 617196 report). <br /> i <br /> cc: File, Book, ASIIRCC Alan F. Clavbourn, P.E. Marcus J.
