The contracted work has now been completed to the satisfaction of the Public Works
Department. A summary of the construction cost is as follows:

Actual Final Cost to City for Contracted Work
$3,511,515.00
$3,245,955.00
$666,981.29
$3,912,936.29
($80,000.00)
($55,297.66)
$3,777,638.63
This final overall cost of the construction contract to TE Roberts was $3,912,939.26 or
11.43% over the original bid amount. However the actual cost to the City for said work
was $3,777,638.63 or 7.58% over the bid amount when one factors in the two
reimbursements associated with the project.
This contract cost overage was a combination of two factors; changes in the actual
amounts of contract bid item quantities paid for, as well as agreed upon change orders
for work not originally included in the contract. In the first case, the actual cost of
contract bid items constructed was $265,560.00 less than the original bid amount. The
majority of the cost savings in bid items is attributed to the deletion of the 12 -inch PVC
water main within the alley between Finley Avenue and 32nd Street. During
construction, the contractor discovered that the original cast iron water main in this alley

was previously replaced with a newer 12 -inch PVC pipe, which is in good condition.
Staff determined that it was not necessary to replace this pipe.
Additional savings related to bid item changes was attributed by an offsetting
reimbursement by the Newport Bay Marina project. During the design phase, staff
included water infrastructure improvements in the plans that were later required to be
constructed by the Newport Bay Marina development. City staff negotiated with the
developer to have the City's contractor construct their conditioned water infrastructure
improvements within the public right-of-way and then received reimbursement check
from Newport Bay Marina for this effort in the amount of $80,000.00.
The project also generated several change orders during the construction phase which
totaled $666,981.29. A large portion of the change order work was attributed to
unforeseen utility conflicts as well as dealing with high groundwater (tidal) level. Due to
many unknown/unmapped, buried utilities pipes (which are common with older streets)
such as Newport Boulevard, the contractor had to revise the pipeline alignment in order
to avoid utility conflicts. In addition, we encountered a significant amount of
groundwater at depths as high as 2 feet below ground level. Due to the high tidal
groundwater level, in combination with our efforts to minimize business and traffic
impacts, the contractor needed to install an extensive dewatering system and also
occasionally work at night which impacted production rates.
One of the directed change orders was associated with the Orange County Sanitation
District (OCSD) Sewer Force Main improvements on West Coast Highway. As
construction of the project commenced, staff requested TE Roberts to add the
replacement of a water main across West Coast Highway by Dover Drive that was
originally going to be replaced by OCSD as part of their Sewer Force main project on
Pacific Coast Highway. The original water main was removed by OCSD's contractor,
Kiewit, in September 2014 to make way for their replacement sewer force main. Kiewit
was to have this water main replaced prior to the summer months, however was behind
schedule and was not going to be able to provide the necessary resources to complete
the work per the approved schedule. Since this was one of two water mains that served
the Bayshores community and is also a critical back feed to the Lido Island, the City
negotiated with OCSD for our contractor (TE Roberts) to install the necessary waterline
and complete this work for OCSD. The cost of this work was charged to the project;
however, OCSD has since reimbursed the City its cost of $55,297.66 for this work.
A summary of the project schedule is as follows:
Estimated Completion Date per Baseline Schedule May 20, 2016
Notice to Proceed June 22, 2015
Contract Completion Date with Approved Extensions June 24, 2016
Actual Substantial Construction Completion Date April 22, 2016
The project was substantially completed as of April 22, 2016. Some miscellaneous
close-out items, operation and maintenance turnover, and post -substantial completion
activities needed to be finalized prior to this Notice of Completion action.
