The Water Main Master Plan Replacement project (Contract No. 4920) addressed
replacement of old cast iron water mains identified in the Water Main Master Plan for
the Corona del Mar community. These were older water mains installed in the 1930’s
that deteriorated, had experienced higher levels of line breaks in the past and have now
outlived their useful life. The contract provided for the construction of new water mains,
valves, services, and fire hydrants for Goldenrod Avenue, Marguerite Avenue, First
Avenue, Alley 18-C and Alley 23-C.
The contract was completed to the satisfaction of the Public Works Department. A
summary of the contract cost is as follows:
Original bid amount:
$1,063,500.00
Actual cost of bid items constructed: $800,450.00
Total change orders: $94,826.39
Final contract cost: $895,276.39
The actual cost of bid items constructed was 15.8 percent below the original contract
amount. During the construction, the contractor did encounter unforeseen underground
conditions associated with the existing pipelines, utilities and connections. During the
construction, it also became necessary for the contractor to request financial assistance
from their bonding company in order to settle numerous claims made by subcontractors
and suppliers. As a result, Public Works and Municipal Operations staff spent an
extraordinary amount of time and effort assisting the contractor to keep the project
moving forward to completion.
During the construction phase, the contractor also requested deletion of the water main
work for Goldenrod Avenue and the Coast Highway intersection and Marguerite Avenue
from the original scope due to staffing and financial issues which limited/hindered the
resources needed to complete the work in a timely manner. City staff felt it would be

prudent and beneficial to both parties to honor this request to delete the work as well as
avoid traffic-related issues associated with the holiday season approaching.
The contractor was substantially completed with all work by November 1, 2015,
excluding the two streets mentioned above. However due to the Christmas holiday,
street trench re-paving efforts were rescheduled and completed by January 18, 2016.
The water replacement work for Goldenrod Avenue and Coast Highway has been
repackaged and re-bid for consideration by City Council within a new project. Staff will
look at options to rebid and complete the water replacement work for Marguerite
Avenue in future water projects.
A summary of the project schedule is as follows:
ENVIRONMENTAL REVIEW:
City Council found this project exempt from the California Environmental Quality Act
(CEQA) pursuant to Section 15301(c). This exemption covers the minor alteration of
