The number of collars was increased to seven and the size of each collar was <br /> increased to provide an additional 0.5 foot projection in each direction (2.5 foot total <br /> projection). Seven collars 10'0" wide by 8'8" high were constructed at 22'0" center-to- <br /> center along the centerline of the new conduit. The first (upstream) collar was placed at <br /> STA 1 +38.6;the last (downstream) collar was placed at STA 2+70.6. Dimensions of the <br /> lower two collars (STA 2+48.6 and 2+70.6) were limited by the presence of bedrock. <br /> Both collars were keyed into competent bedrock six inches minimum as specified on the <br /> approved plans. <br /> The approved plans show a preformed bituminous joint filler placed around the <br /> conduit at each cutoff collar location to provide a structural separation of the conduit and <br /> collar. Due to the rigid nature of the bituminous joint filler and the unavailability of curved, <br /> preformed sections, alternate materials were substituted. A flexible foam expansion joint <br /> filler was used in place of the bituminous joint filler, and was approved as an acceptable <br /> substitute by the Office of the State Engineer. <br /> Outlet Headwall Location. The outlet headwall at the discharge end of the new <br /> conduit was moved from STA 2+95, as shown on the approved plans, to STA 2+90.1. <br /> This change reduced the required number of reinforced concrete pipe sections by one. <br /> Hydraulic performance of the outlet conduit was not impacted by this modification. <br /> Gate Stem and Stage Marker Pedestals. The sluice gate support pedestal spacing <br /> was changed to 15'4" along the centerline. This change occurred subsequent to <br /> discussions with the sluice gate manufacturer and will provide a more uniform support of <br /> the gate stem. Shop drawings for the sluice gate are provided as Appendix H. <br /> Stage marker support pedestals are shown 14-inches square on the approved plans. <br /> Six of the seven pedestals were constructed 16-inches in diameter round while the <br /> uppermost pedestal was constructed 14-inches square. <br /> 4 <br />
