The Underground Utility Assessment District No. 116, 116B and UUD22-1 project is the
second City of Newport Beach (City) managed and constructed utility undergrounding
project that undergrounded overhead power, telephone and cable facilities. AD 116 is the
area bounded by 44th Street to 38th Street and Balboa Boulevard to Rivo Alto Channel.
AD 116B is on the east and west side of Balboa Boulevard between 47th and 45th Street.
UUD22 Phase 1 is located on Balboa Boulevard between 36th Street and West Coast
Highway.
The contract specifically provided for traffic control; water pollution control; trenching;
construction of vaults, vents, pull boxes, handholes; installing conduit; and associated
items necessary such as backfilling, pavement restoration, resurfacing and replacement
of existing concrete improvements for the conversion of existing overhead electrical
power, telephone, and cable television services to underground locations.
The project was very complex and proved to be challenging due to issues with parking
and traffic management, groundwater, and obstructions with abandoned gas, water main
and street light conduit. There were also water main breaks and water service leaks that
needed repair, and additional effort was required to remove the old concrete street
sections on Balboa Boulevard in order to trench and install conduits. Furthermore, crews
working at various locations along Balboa Boulevard, River Avenue and adjacent alleys
encountered existing pockets of oil left over from prior historic drilling operations that
required special handling.
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: $3,813,399.61
Actual Cost of Bid Items Constructed: $3,566,503.93
Total Change Orders: $610,247.08
Final Contract Cost: $4,176,751.01
Eleven change orders totaling $610,247.08 in increased contract cost were approved as
part of the project. The change orders addressed costs for the abovementioned work
including costs to install 3 -inch conduit and pull boxes for the City's traffic signalization
system and additional concrete alley restoration not included in the original bid.
With the completion of the project, the final contract cost is approximately 9.5 percent
above the original bid amount. A summary of the project schedule is as follows:
Estimated Start of Construction per Annual Baseline Schedule June 3, 2019
Actual Start of Construction Per Notice to Proceed June 17, 2019
Extended Contract Completion Date Inclusive of Extra Work October 19, 2021
Actual Substantial Construction Completion Date June 12, 2020
