ABSTRACT:
On January 22, 2013, City Council awarded Contract No. 4603, Corona del Mar Water Transmission Main
Pipeline Improvements project to T.E. Roberts Inc., for a total contract cost of $4,402,750.00 plus

The work necessary to complete this contract included constructing a new 30 -inch water main from the
existing 30 -inch main in Pacific View Drive, down the recommended alignment to the existing 30 -inch main
at the intersection of East Coast Highway and MacArthur Boulevard. The project also included constructing
a new 24 -inch transmission main on Carnation Avenue between East Coast Highway and Bayside Drive.
In addition to the new pipeline work, the project relocated the City's current pressure regulator structure
that joins with the Metropolitan Water District's CM -1 system connection, currently located in East Coast
Highway at Fernleaf Avenue to a new location that is out of the Coast Highway right -of -way and onto
Dahlia Avenue.
The contract was completed to the satisfaction of the Public Works Department. A summary of the contract
cost is as follows:
Original bid amount: $4,402,750.00
Actual cost of bid items constructed: $4,387,710.00
Total change orders: $ 409,091.56
Final contract cost: $4,796,801.56
The actual cost of bid items constructed was $15,040.00 less than the original bid amount due to
elimination of several fire hydrants that were unnecessary and substitution of PVC pipe for a segment of
16" water main that was originally designed as steel pipe. The final contract cost was approximately 8.95
percent above the original bid amount with change orders totaling $409,091.56. The larger change orders
included additional asphalt concrete (AC) removals due to extremely thick pavement not known during the
design process, additional AC paving on MacArthur Boulevard on the opposite side of the street unrelated
to the pipeline work and several water main alignment adjustments for utilities not shown on the existing
records but were required. The contractor performed well on this project and staff took advantage of the
low bid prices to modify additional valves on Coast Highway, San Joaquin Hills Road and Yacht Coquette.
Staff also authorized overtime and extra work to expedite construction on MacArthur Boulevard and Pacific
Coast Highway as a means to lessen the impact on traffic and the community.
A summary of the project schedule is as follows:
Estimated Completion Date per 2012 Baseline Schedule September 02, 2014
Project Awarded for Construction January 22, 2013
Contract Completion Date with Approved Extensions August 11, 2014
Actual Substantial Construction Completion Date June 06, 2014
Staff notes that this was a complex project that significantly impacted the community, especially the
residents and businesses of Corona del Mar. We sincerely appreciate our residents' and business owners'
patience with this project, and are thankful that it was completed successfully - and even in advance of the
expected completion date. The work done here by our contractor was quality work, and will assure greater
reliability for our community for decades to come.
