The West Irvine Terrace and Balboa Island Water Main Replacement Project (Contract
No. 7966-1) replaced older, deteriorated cast-iron and asbestos cement water mains,
installed between 1936 to 1953, that had outlived their design life and were due to be
replaced. The City's Water Master Plan identified these water main replacements in the
West Irvine Terrace community. Additionally, staff accelerated design of water main
replacements for portions of Balboa Island and included it with the Irvine Terrace work in
order to complete these critical water system improvements before the anticipated utility
underground construction of Assessment District 124. The project also included water
main replacements on Little Balboa Island for existing cast-iron water mains that were
experiencing main breaks and reduced capacity due to identified corrosion.
During construction, staff was informed that the existing cast iron water mains located on
Balboa Island along the North Bay Front alleys between Onyx Avenue and the Grand
Canal were in conflict with the undergrounding of utilities (AD-124 — Phase 0). For that
reason, this area's water main replacement was added to the project and the proposed
water main replacements for Little Balboa Island were deleted. The Little Balboa mains
were repackaged and bid with the Balboa Island Water Main Replacement Phase 3
project, which is now currently in construction.
Although there were minimal issues, some of the challenges during construction were
related to shortage of materials and material price increases for water service fittings,
exporting and importing backfill material due to unsuitable soils in the West Irvine Terrace
community, additional paving and interfering existing utilities.
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: $4,222,889.00
Actual Cost of Bid Items Constructed: $3,645,050.00
Total Change Orders: $953,764.23
Final Contract Cost: $4,598,814.23
Six change orders totaling $953,764.23 in increased contract cost were approved as part
of the project and $577,839 of work (Little Balboa Island water lines) was removed from
the original contract. The change orders addressed costs for the abovementioned work
including costs for a 2-inch air/vac assembly, drainage work at the Newport Yacht Club,
valve improvements at the Bayside Drive water regulating station, and costs related to
nighttime work on Marine Avenue, which included ferry operations assistance during the
bridge closure.
A summary of the project schedule is as follows:
Estimated Start of Construction per Annual Baseline Schedule January 16, 2023
Actual Start of Construction Per Notice to Proceed January 30, 2023
Extended Contract Completion Date Inclusive of Extra Work January 24, 2024
Actual Substantial Construction Completion Date January 24, 2024

business district, water main replacement work for the North Bay Front alleys along
Marine Avenue was postponed until after the Christmas holidays, delaying the close-out
of this contract. The project was substantially completed to the satisfaction of the Public
Works Department by January 24, 2024.
