DISCUSSION: Overall Contract Cost/Time Summary Awarded Contract Final Total Contract Total Contract Percent Contract Amount Amount Change Amount Cost Change $4,308,179.00 $4,827,865.04 $519,686.04 12.1% Allowed Contract Time + Approved 160 Actual Time Used (Days) 160 Extensions (Days) _ The Underground Utility Assessment District No. 113 (AD 113) project is the fourth City of Newport Beach managed and constructed utility undergrounding project that undergrounded overhead power, telephone and cable facilities. AD 113, in the west Balboa Island area, is bounded by Collins Island, Agate Avenue, North Bay Front and South Bay Front (Attachment A). 9-1 Underground Utility Assessment District No. 113 — Notice of Completion for Contract No. 7979-1 November 19, 2024 Page 2 The contract specifically provided for traffic control, water pollution control, trenching, dewatering, construction of vaults, vents, pull boxes, handholes and installing conduits. Additionally, the contract included trench backfilling, pavement restoration, and replacement of concrete improvements such as sidewalks and curbs. There were minimal issues during construction, but the project proved to be challenging due to utility companies' design changes, a supply chain related shortage of materials, an increase in the price of materials, water main breaks and water service leaks. The contracted work has been completed to the satisfaction of the Public Works Department. A summary of the construction cost is as follows: Original Bid Amount: $ 4,308,179.00 Actual Cost of Bid Items Constructed: $ 4,308,179.00 Total Change Orders: $ 519,686.04 Final Contract Cost: $ 4,827,865.04 The final total contract amount was $4,827,865.04, which was approximately 12.1 % higher than the original bid amount. This cost increase was due to the issues mentioned above, but primarily due to change order requests from City staff for additional concrete replacement, sewer main point repairs at various locations within AD 113, required water main relocation to accommodate the undergrounding in alley 414A, and overtime costs to expedite vault work near the Balboa Island Ferry on Agate Avenue. A summary of the project schedule milestones is as follows: Estimated Start of Construction per Annual Baseline Schedule August 2, 2021 Actual Start of Construction Per Notice to Proceed September 7,2021 Estimated Contract Completion Date per Annual Baseline Schedule February 25,2022 Actual Substantial Construction Completion Date April 22, 2022 The start of the construction was delayed to minimize traffic impacts associated with the summer peak season. Rain delays, water main breaks, water service leaks, and work related to utility companies' design changes located at the North Bay Front and Collins Avenue area delayed the closeout of this contract. The project was substantially completed to the satisfaction of the Public Works Department by April 22, 2022.
