CHANGE ORDER 2, 091- Nil No. 1 PROJECT West Wabasso Water Lines DATE OF ISSUANCE EFFECTIVE DATE OWNER Indian River County OWNER ' s Contract No. Project No. U ED BY CONTRACTOR : Sheltra and Son Construction Inc. ENGINEER Indian River County/Himanshu Mehta— FEB 1 3 2007 You are directed to make the following changes in the Contract Documents : BOARD OF COUNTY Cn � urrni�N Item # 1 Description : Deduct 530 LF of 6" PVC water main at a unit price of $22 .00 (Total $ 11 , 660. 00) and Add 530 LF of 6" HDPE water main at a unit price of $ 75 . 00. ($ 39,750 . 00) Reason for change order: Total $ 28,090.00 a) Approximately 280 LF of directional bore (HDPE) was needed on 87th Place. In general , the Contract drawings specified a standard open & cut method for installation of the 6 " PVC water main along the property line. The primary reason to employ the directional bore method was to avoid obstructions such as tall dense trees and vegetation area, to avoid a fence and a garden, and to avoid compromising a residential trailer that was too close to the property line. These obstructions were not identified on the survey that was used for the design. b) Approximately 180 LF of directional bore was needed at the end of 61 st Drive. Although most of the road is paved, the last 210 LF of the road was heavily vegetated. Per the Contract drawings, this area was to be cleared along the path of the water main. Upon clearing most of this area, it was determined that first there was a significant drop in elevation and second that there was water pooled at the end of the road. The directional bore method was selected to avoid extensive dewatering and handling of the water and to avoid backfilling the area with soil . Both of these items were not in the scope of the project. These were unknown conditions at the time of the design since the survey did not identify these possible conditions . c) Approximately 70 LF of directional bore was needed on 61 st Drive to avoid open & cut installation of a new residential concrete driveway that was not identified on the survey at the time of the design. Item #2 Description : Add additional 120 LF of 4 " PVC water main at the unit price of $ 19 .00 ( S2,280. 00).- Total 2280 00).Total $ 2,280.00 Reason for change order: The Contract drawings specified extending 160 LF of 4 " PVC to provide water services for seven homes into an area that was not properly platted . This extension was designed to minimize the long service lines that were needed to reach these homes. However, upon installation of this water main it was determined that the location at which this pipe ended was not in a suitable location and that it did not adequately serve the purpose for minimizing the long service line. Therefore, an additional 120 LF of 4" PVC water main was needed in which the shorter service lines provide a better water pressure to the house.
