JAMES ROAD AND KINGS PLACE WATER MAIN REPLACEMENT PROJECT — NOTICE OF COMPLETION AND ACCEPTANCE OF CONTRACT NO. 4775 October 11, 2011 Page 2 DISCUSSION: Overall Contract Cost/Time Summary Construction Final Cost at Contingency Actual Contract Time Contract Award Final construction contract cost: $266,058.20 Contract Time Under or Amount Completion Target Change days Over $249,985.00 $266,058.20 15% or less 6.4% 45 22 The work necessary to complete this contract consisted of distributing notices to affected residents, traffic control, removing interfering portions and abandoning in place existing water facilities, furnishing and installing new water mains, water services, fire hydrants, valves, fittings, waste water lateral and other appurtenances and restoring of all affected surface improvements, and other incidental items of work to complete the project. This project was designed on an emergency basis and constructed with an accelerated schedule due to 3 previous water breaks within the previous 6 months. T.E Roberts began work two days after council award and completed 20+ days ahead of schedule. The residents were delighted to see the old water main replaced in such a quick and efficient manner. This project demonstrated the cooperative work possible between a. good contractor and city staff from the MOD and Public Works Departments. The new C -900 PVC line replaces the old ACP main which should prevent further public property damage from additional water breaks. Furthermore, the City authorized the current slurry seal contractor American Asphalt South to slurry the street after all trench work had been completed. This work was deemed appropriate due to the extensive trenching for the water line as well as the service laterals that crisscrossed the street. The slurry seal will extend the pavement life and eliminate the need for an another construction project in the near future thus minimizing impacts to residents 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: $249,985.00 Actual cost of bid items constructed: $252,933.20 Total change orders: $13,125.00 Final construction contract cost: $266,058.20 The final construction contract cost is approximately 6 percent above the original bid amount. The asphalt tonnage was over the estimate due to the additional paving the ST. JAMES ROAD AND KINGS PLACE WATER MAIN REPLACEMENT PROJECT — NOTICE OF COMPLETION AND ACCEPTANCE OF CONTRACT NO. 4775 October 11, 2011 Page 3 contractor performed in this area per City request. Additional paving was required to permanently repair the damaged pavement in front of the home that had been flooded twice due to pipe failures. Repair crews had temporarily patched the street knowing this pipeline job would be coming through at a later date. The native clay subgrade was found to be unsuitable for use as backfill so a change order in the amount of $13,125 was approved to bring in suitable base material and haul off the native material. A summary of the project schedule is as follows: Estimated completion date per July 2010 Schedule: October 21, 2011 Project Awarded for construction: July 12, 2011 Contract Completion Date Plus Approved Extensions: September 15, 2011 Actual Construction Completion Date: August 12, 2011 ENVIRONMENTAL REVIEW: City Council found this project exempt from the California Environmental Quality Act ( "CEQA ") pursuant to Section 15301(c).
