The Via Lido Soud and Nord Water Main Replacement Project (Contract No. 7645-2)
replaced cast iron water mains identified in the Water Master Plan for the outer ring
roadway on Lido Isle. These were older, deteriorated water mains installed in the 1930s
that had outlived their design life and were due to be replaced. This project also included
water main replacement for the existing, 10 -inch, cast iron water main located on
Via Antibes.
The contract specifically provided for the removal of existing deteriorated cast iron water
mains and installing new PVC pipe, valves, fire hydrants, and water services; pavement
restoration; traffic control; and other appurtenant work as required by the contract.
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: $3,787,401.00
Actual Cost of Bid Items Constructed: $3,399,370.00
Total Change Orders: $650,183.68
Final Contract Cost: $4,049,553.68
After award of this contract and during construction, City of Newport Beach staff
discovered a water main break on a critical 12 -inch water main located nearby on Coast
Highway near Superior Avenue. After extensive efforts by City staff it was necessary to
bring in an outside contractor for assistance. The break ended up being over 15 -feet deep
in ground water inside a casing that crossed under Coast Highway. As TE Roberts was
mobilized with the crews and equipment necessary to complete the emergency repairs,
they were re -directed to assist the City with the repair. The emergency repair work
included potholing, repair clamps, relocation of an existing 3 -inch conduit that was
interfering with repairs, and installation of a new 12 -inch butterfly valve, fittings, concrete
thrust blocks, pipe lining inside the casing and a 2 -inch air/vac assembly.
The other significant change order, was due to the existing street pavement on Via Lido
Nord and Soud being thicker than originally planned. An additional 1,718 tons of asphalt
were required for base paving operations.
Four change orders totaling $650,183.68 in increased contract cost were approved as
part of the project. With savings on the original bid items, approximately $388,000, the
final contract was approximately 6.9 percent higher than the original bid amount. The final
contract cost was $4,049,553.68. The savings on the original bid items included less 6 -
inch PVC pipe constructed, minimal private property restoration work, and deletion of the
asphalt pavement grind and overlay bid item due to the Lido Island Ring Roadway
Pavement Rehabilitation project scheduled for January 2022.
A summary of the project schedule is as follows:
Estimated Start of Construction per Annual Baseline Schedule October 26, 2020
Actual Start of Construction Per Notice to Proceed November 2, 2020
Extended Contract Completion Date Inclusive of Extra Work October 19, 2021
Actual Substantial Construction Completion Date May 3, 2021
