• <br />• <br />Change Order Form <br />No. 1 <br />DATE OF ISSUANCE: EFFECTIVE DATE: <br />OWNER: Indian River County <br />CONTRACTOR Duininck, Inc. • <br />Project: Dunes Golf Course Irrigation System Project <br />OWNER's Project No.148060 <br />You are directed to make the following changes in the Contract Documents: <br />Description: <br />Additional Part and Full Circle Sprinklers per Contract and Pump Station Zee Pipe <br />Connection <br />Reason for Change Order: <br />The original design of the irrigation system had 993 valve -in -head sprinklers for the entire <br />property. During installation, there are adjustments that need to be made in order to have <br />proper coverage of water. These additional 23 heads, basically one per hole, will enhance <br />the golf course in certain areas where we didn't have water before. In lieu of coming back <br />later and paying triple the price, it is best to install them now than later because of cost. <br />The connection we were to use was an old metal corroded pipe and the pipe outlet was <br />reduced to a smaller size than what we were hooking up to so it made sense to do this work <br />now rather than later and have a nice, clean connection with the correctly sized outlet. <br />The specification did not specify to connect to existing pump above or below ground. We <br />are building a new Z so we will not have to rely on trying to connect to existing old and <br />corroded metal pipe. <br />Much of the connection price is to change out an existing bottleneck reducer that was <br />installed when the new pump station was purchased years ago. The existing pump header <br />is 10 inches in diameter and the Z pipe is 12 inches in diameter yet the pump goes from 10 <br />inch to 8 inch then 8 inch to 12 inch with a bottleneck in the middle. We also need to <br />include a saddle on the new the pipe to accommodate their flow meter. <br />This way the system is complete and new and HDPE all the way above ground and will <br />eliminate the very old existing bare metal pipe that is in the ground currently and below or in <br />the existing water table. <br />Attachments: (List documents supporting change) <br />Work Order Proposal from Duininck, Inc. <br />Change Order - 1 <br />97 <br />
