Webb, Public Works Director - 949-644-33111 dawebb@newportbeachca.gov PREPARED BY: Frank Tran, Civil Engineer, ftran@newportbeachca.gov PHONE: 949-644-3340 TITLE: Newport Heights Sewer Improvements — Notice of Completion for Contract No. 7028-2 (Project No. 17503) ABSTRACT: On June 28, 2016, City Council awarded Contract No. 7028-2 for the Newport Heights Sewer Improvements project to Mike Prlich and Sons, Inc, California. The work is complete and staff requests City Council acceptance and close out of the contract. RECOMMENDATIONS: a) Accept the completed work and authorize the City Clerk to file a Notice of Completion for the project. On June 28, 2016, the City Council found this project exempt from the California Environmental Quality Act (CEQA) pursuant to Class 2 Section 15301(c); b) Authorize the City Clerk to release the Labor and Materials Bond 65 days after the Notice of Completion has been recorded in accordance with applicable portions of the Civil Code; and c) Release Faithful Performance Bond one year after acceptance by the City Council. FUNDING REQUIREMENTS: Fund for the construction contract was expensed from the following account: Account Description Account Number Amount Wastewater Enterprise 71201-980000-17503 $ 1,467,514.64 Total: $ 11467,514.64 7-1 DISCUSSION: Newport Heights Sewer Improvements — Notice of Completion for Contract No. 7028-2 (Project No. 17503) April 25, 2017 Page 2 Overall Contract Cost/Time Summary Awarded Final Cost at Contingency Actual % Due to % Due to Contract Amount Completion Allowance Contract Directed Unforeseen Change Change Change $1,575,377.00 $1,467,514.64 10% or less -6.85% -29.81% +22.96% Allowed Contract Time + 182 Actual Time -18 Approved Extensions (days) = Under (-) or Over (+) The contracted work has now been completed to the satisfaction of the Public Works Department. A summary of the construction cost is as follows: Original bid amount: Actual cost of bid items constructed: Total Change Orders: Final Contract Cost: $1,575,377.00 $1,105,821.00 $361,693.64 $1,467,514.64 The actual cost of contract bid items constructed was $107,862.36 less than the original planned bid amount. The majority of the cost savings is attributed to the deletion of bid items to reconstruct concrete valley gutters and slurry coat the remaining asphalt surface to keep the alley in good condition should the potential Utility Undergrounding District being considered at the time of award of this project be approved. With the failure of the Utility District to be approved and formed, this concrete gutter and slurry work was removed from the contracted bid items as the planned alley reconstruction project for the Newport Heights area is now being moved up and should start in by summer of this year. The project also included six change orders for a total amount of $361,693.64, which was approximately 23 percent of the original bid amount. Notable change orders were for addressing the many unanticipated/unknown underground utilities that required more labor for hand digging around them, changes in sewer lateral size from 4 -inch to 6 -inch, and the need for imported trench fill material to replace the unsuitable sub -grade materials encountered during the project. A summary of the project schedule is as follows: Estimated Completion Date per Baseline Schedule December 2, 2016 Notice to Proceed for Construction July 25, 2016 Contract Completion Date with Approved Extensions April 28, 2017 Actual Substantial Construction Completion Date April 4, 2017 7-2 Newport Heights Sewer Improvements — Notice of Completion for Contract No. 7028-2 (Project No. 17503) April 25, 2017 Page 3 ENVIRONMENTAL REVIEW: On June 28, 2016, City Council found this project exempt from the California Environmental Quality Act (CEQA) pursuant to Class 2 Section 15301(c) (minor alterations of existing public facilities involving negligible 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.
