Discussion:
On May 8, 2007, the City Council authorized the award the Industrial Way 36 -Inch
Water Main Replacement Project to SJ &B Group, Inc. The contract provided for the
construction of a 36 -Inch water main to replace an ageing and undersized water main,
Water facilities within 16`" Street and Industrial Way were targeted to be replaced due
to their age and a need for increased capacity as part of the Water Master Plan. The
existing 14 -inch system was built in 1950 and has outlived its useful life. In addition,
there is an existing 30 -inch transmission main that was built in 1923 and traverses the
General Services yard parallel to Industrial Way. The project replaced the existing 14-
inch and 30 -inch mains with a single main located within the Industrial Way street right -
of -way between Superior Avenue and Old Newport Boulevard /15 "' Street.
During the construction of the project, the City was informed that the contractor, SJ &B
Group, Inc., filed a notice of default with its bonding company Safeco and would be
unable to independently complete the project. The City worked with the bonding
company to rebid the remaining portion of the work which included the installation of the
36 -inch pipe. The bids received by Safeco were significantly above the original bid
price of the remaining bid items. In an effort to expedite the project, the City worked

with representatives from Safeco to fund SJ &B Group to finish the project. SJ &B
remobilized and finished the project.
The contract has now been completed to the satisfaction of the Public Works
Department. A summary of the contract cost is as follows:
Original bid amount: $990,285.00
Actual amount of bid items constructed: 869,447.07
Total amount of change orders: 122.096.57
Final contract cost: $991,543.64
The decrease in the amount of actual bid items constructed over the original bid
amount resulted from a reduced scope of paving operations and the removal of a
smaller amount of interfering water line pipe. The final overall construction cost
including Change Orders is .12 percent over the original bid amount.
10 Change Orders in the amount of $122,096.57 were approved on this project. The
Change Orders were as follows:
CO 1 — Additional paving on gate valve and new Air -Vac on Superior Avenue.
CO 2 — Dig out and replace 12 -Inch gate valve
CO 3 — Additional sidewalk, curb and gutter replacement due to realigning pipe. Cost
from pipe manufacturer for redesigning pipe.
CO 4 — Change order rescinded.
CO 5 — Remove, replace thrust block on 18 -inch water line to allow installation of pipe.
CO 6 — Realign sewer laterals around water line and replace damaged curb and gutter.
CO 7 — Removal of slurry surrounding the tie -in. Costs associated with improperly
closing valve requiring Contractor to shut down until City crews were able to get a
proper shut down of the water line.
CO 8 — CALTRANS permit fees and extra slurry around pipe.
CO 9 — Overtime charges to complete the tie -in work over the weekend so as to not
impact area residents and businesses during the week.
CO 10 —Additional traffic loops that were required to be cut in.
All work was substantially completed by August 29, 2008, approximately eight months
past the scheduled completion date of December 28, 2007. Extra time was needed to
complete the project due to a redesign required to avoid unmarked utilities and to
accommodate working with the bonding company as outlined above. The following is a
summary of the project schedule:
