BOOK 107 PAGE <br />11.H.1. 16th STREET WATER AND FORCE MAIN RELOCATION <br />-MATERIALS FROM U.S. FILTER/DAVIS - CHANGE ORDER NO. 1 - <br />DRIVEWAYS, INC. <br />The Board reviewed a Memorandum of October 12, 1998: <br />DATE: OCTOBER 12, 1998 <br />TO: JAMES E. CHANDLER <br />COUNTY ADNIINISTRATOR <br />FROM: DONALD R HUBBS, P.E. l� <br />t <br />DIRECTOR OF CES <br />PREPARED MICHAEL C. HOTCHKISS, P.E. 99 <br />AND STAFFED ENVIRONMENTAL ENGINEER <br />BY: DEPARTMENT OF UTILITY SERVICES <br />SUBJECT: 10 STREET WATER AND FORCE MAIN RELOCATION <br />INDIAN RIVER COUNTY PROJECT NOS. UW -98 -02 -DS AND US- <br />98-03-CS9 CHANGE ORDER NO.1 <br />On May 12, 1998, the Board of County Commissioners approved a labor contract with Driveways, <br />Inc. in the amount of $48,040.54 to relocate miscellaneous water and force mains in conflict with a <br />proposed Florida Department of Transportation (DOT) drainage project in the Rockridge <br />subdivision (see attached minutes of meeting). The labor contractor has begun exploration of field <br />conditions. During review of the drainage project survey stakes, two additional conflicts between <br />water mains and drainage pipes were identified. Also, two additional valves were identified as <br />needed to isolate the area of construction from the residential customers in the area. <br />Upon review of the water distribution system configuration, it was determined that over 400 <br />customers will lose water service for a period of up to six hours in order to install isolation valves <br />around the area of construction. Even though the work can be done during off-peak hours, Utilities <br />staff is considering an alternative method for installing the necessary valves. A new utility device <br />known as an Insta-Valve can be cut into a water main under pressure, without interrupting service. <br />This method of valve installation will prevent damage that can occasionally occur to hot water <br />heaters and other various equipment when service to such a large area is suspended and then re- <br />pressurized. Furthermore, fire protection will be maintained by utilizing Insta Valves. <br />The purpose of this change order is to accommodate D.O.T.'s drainage project through relocation <br />of conflicting water mains and substitute Insta Valves for conventional isolation valves to maintain <br />water service to Rockridge Subdivision customers, therefore avoiding any extended water outages. <br />The cost breakdown of the additional work is as follows (see attached change order): <br />October 20, 1998 <br />70 <br />
