i <br />y <br />'i'- <br />REQUEST FOR COUNCIL ACTION <br />DATE: August 25, 1997 <br />Department Approval: <br />Name Gregory A. Gappa <br />Title Director of Public Services <br />% <br />\ \ <br />ITEM NO.: / ^ <br />Administrator Reviewed:Agenda Section: <br />Engineer's Report <br />Item Description: Change Order No. 1 Bracketts Point/Bay Ridge Sanitary Sewer Project <br />This change order includes several items. The first item is to increase the amount of directional <br />bored pipe along County Highway 51. This is required as a condition of the permit from He'i iepin <br />County to minimize the impacts to the County Highway. <br />The second item is increase the amount of directional bored pipe across the Jundt property and <br />increase the pipe quantity because of minor alignment changes in this area. These changes were <br />agreed to during the easement acquisition process to protect large trees and minimize the impacts <br />to the property. <br />The third item is increase the amount of directional boring along Bracketts Point Road because <br />of extremely poor soil conditions. Even with the extensive installation of well points for <br />dewatering, and the use of light weight aggregate, it was not possible to stabilize the pipe <br />foundation. Access problems were also experienced. Poor soils and high ground water resulted <br />in larger excavations making i: very difficult to keep the road open for resident and emergency <br />vehicle access. <br />Possible poor soil conditions were anticipated during project design and an alternative was bid to <br />allow for additional directional boring, so unit prices are available for this work. When the <br />contract was awarded, the alternative bid was inadvertently not included. <br />An alternative was also bid for a grinder pump to serve a residence along Shoreline Drive. This <br />was bid as an alternative because we were not sure if we would obtain a competitive price for this <br />pump. A reasonable price was obtained for this grinder pump, but this alternative was not <br />included in the contract award. <br />CUUNCn. ACTION REQUESTED: <br />Motion to approve Change Order No. 1, Bracketts Point/ Bay Ridge Sanitaty Sewer project, in <br />the amount of $55,538. <br />J
