The contract provided for the removal and replacement of water valves, fire hydrants, water meters constructing 6 and 8 -inch PVC water main and restoration of all surface improvements. The contract has now been completed to the satisfaction of the Public Works Department. A summary of the contract cost is as follows: Original bid amount: $629,580.00 Actual amount of bid items constructed: $592,080.00 Total amount of change orders: $86,897.54 Final contract cost: $678,977.54 Four change orders resulted from old abandoned utilities that were not shown on current utility maps and various delays. In addition there were some fairly significant delays associated with coordinating this work with the concurrent Underground Utilities Assessment District 99 -2. The final overall construction cost including Change Orders was 7.8% percent over the original bid amount. The first Change Order was a credit in the amount of $(12,820.20) provided for rental of the City's water main bypass equipment. West Ocean Front Alley Water Main Replacement - Completion and Acceptance of Contract No.4007 July 14, 2009 Page 2 The second Change Order in the amount of $15,114.55 provided for delays due to unforeseen utilities, water main shutdown complications and extra pavement not shown on plans. The third Change Order in the amount of $8,117.62 provided for delays due to complications with replacing existing sewer clean outs (SCO) due to interfering existing underground utilities and additional unforeseen abandoned utilities in the new water main alignment. The fourth Change Order in the amount of $76,485.57 provided for delays due to coordination efforts with AD 99 -2, which resulted in additional costs to the contractor for by -pass setups. A summary of the project schedule is as follows: Estimated completion date per June '08 schedule: March 31, 2009 Project award for construction: November 12, 2008 Estimated completion date at award: April 3, 2009 Actual substantial construction completion date: April 10, 2009 Construction was completed slightly later than anticipated due to coordination requirements of working with AD 99 -2. During the course of the project, it was determined that most of the sewer clean outs (SOCs) would not be able to be replaced due to interfering utilities. Therefore, this item was deleted from the contract. With this change, the total amount of savings for the sewer fund is $60,454.00 All of the water main work was coordinated with the Assessment District 99 -2's (AD 99- 2) contractor, Arizona Pipeline (AP). Due to the tight coordination of this work and confined work areas, there were some delays encountered as both crews had to work in the same alley to install conduits, and water lines. The overall cost of extra work and delays for JTM resulted in total change orders of $86,897.54. The total contract work plus change order work is 7.8% over the original contract amount. An amount of $48,000.00 is directly related to AP delays. It is recommended that $48,000 be charged to AD 99 -2 funds to cover the associated delays by AP. Environmental Review: The project was determined to be exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15301 of the CEQA Implementation Guidelines at the time the project was authorized by the City Council. This exemption covers the repair, maintenance and minor alteration of existing public facilities with negligible expansion.
