A summary of this contract's construction cost is as follows: Original bid amount: Actual Cost of Bid Items Constructed: Total Change Orders: Final contract cost: $257,850.00 $252,850.00 $ 20,319.62 $273,169.62 The actual cost of bid items constructed was $5,000.00 less than the original bid amount due to not having to replace a 12 -inch water valve. During the course of the project, the contractor ran into several unforeseen underground obstacles that added significant costs to the project. The first unforeseen item was very hard slurry backfill used in the original water main trench. This backfill had to be broken out with machinery that delayed production significantly. The second unforeseen item was an obstruction from a high pressure gas line. The alignment of the water main had to be redesigned in the field to pass underneath the gas main. The redesign required additional fittings, air -vacuum assembly, labor and time to construct. The final contract cost was approximately 5.9 percent above the original bid amount with three change orders totaling $20,319.62. The change orders included the abovementioned work. A summary of the project schedule is as follows: Estimated Completion Date per Baseline Schedule May 13, 2016 Project Awarded for Construction March 22, 2016 Notice to Proceed May 2, 2016 Contract Completion Date with Approved Extensions June 20, 2016 Actual Substantial Construction Completion Date June 16, 2016 The project was substantially completed as of June 16, 2016. However, the project was slightly delayed in an effort to coordinate with the adjacent East Coast Highway Corona del Mar Entry Project and the Orange County Marathon. 10-2 Water Main Replacement at Goldenrod Avenue and Coast Highway Notice of Completion for Contract No. 7010-1 (15W01) August 9, 2016 Page 3 ENVIRONMENTAL REVIEW: At the March 22, 2016 City Council meeting, the project was found to be exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15302(c) (Reconstruction of existing facility involving negligible or no expansion of capacity) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no potential to have a significant effect on the environment.
