ATTACHED SUPPORTING DOCUMENTS:

BACKGROUND AND DISCUSSION:
The design for the Ladera Linda Community Park Project (Project) called for re-using the
existing main water service connection line and associated backflow prevention device
(backflow preventer) as it was in good condition and of sufficient capacity for re-use. The
purpose of the backflow preventer is to prevent water from reversing direction from a
1
customer’s water service line into the utility company’s water main water line, effectively
protecting the integrity of the main water line’s operating pressure and water quality.
During construction inspection being performed by California Water Service (Cal Water),
which provides potable water service to the Ladera Linda Community Park (Park), Cal
Water notified the City that the existing backflow preventer could not be reused and had
to be relocated closer to the street to provide direct access for their routine inspection and
testing.
In response to Cal Water’s directed requirements, the City engaged the services of Ferrari
Backflow, Inc. (Ferrari) and issued a purchase order in the amount of $22,995
(Attachment B) to: (1) remove the existing backflow preventer, (2) install copper pipe in
the section where the existing backflow preventer is removed, and (3) install a new
backflow preventer and associated foundation pad, enclosure, and connecting copper
pipe between the park’s existing water service meter and the new backflow preventer.
During the excavation work to install the new backflow preventer and associated
connecting pipe and foundation, the existing sections of pipe to be connected to the
backflow preventer were discovered to be made of PVC and cement. The sections of
PVC pipe could not be re-used to properly connect with the new backflow preventer’s
copper piping and was not anticipated as part of Ferrari’s original scope of work. As a
result, extra work to remove and replace the existing PVC pipe with additional (new)
copper pipe was required so that suitable connections could be made to the existing
sections of reusable cement pipe. Transition fittings were also required to complete the
copper-to-cement pipe connections and were not part of Ferrari’s original scope of work.
Additionally, the existing irrigation line and associated backflow prevention device were
discovered to be in poor condition and required replacement, including the installation of
a new foundation pad and enclosure.
To serve their intended functions, both backflow preventers were installed in-line with the
main water service line and as a result required a temporary shut-down of water service
to the park to complete the work safely. As such, time was of the essence to complete all
scopes of work and minimize water service interruptions to the park. Alternative solutions
to addressing the above-described unforeseen conditions, including suspension of the
work and reverting the water service infrastructure to pre-job conditions would have
imparted significant additional costs associated with repeating portions of the work in the
future, providing a temporary source of water to the park, and potential fees for non-
compliance with Cal Water’s requirements for providing water service to customers.
In summary, Ferrari had to perform additional work above and beyond the scope of their
original invoice to complete installation of the main water service backflow preventer and
restore water service to the park in a timely manner. The additional cost required to
perform the additional unforeseen work was $5,000, for a total installation cost of $27,995 ,
as reflected in the revised invoice (Attachment A). Staff reviewed the invoice for Ferrari’s
extra work and found it to be fair, reasonable and reflective of the hours required to
perform the work.
The revised purchase order amount exceeds the $25,000 maximum contract authority of
2
the City Manager, as originally authorized. Therefore, City Council’s ratification of the total
payment to Ferrari is required.
CONCLUSION:
The scope of work originally contracted with Ferrari to install a new backflow preventer
and associated work was increased due to unforeseen conditions, resulting in a total cost
of $27,995, which exceeds the City Manager’s contracting authority. Staff did not stop
work and seek City Council authorization before proceeding because this would have
resulted in significant additional costs and disruptions. Therefore, Staff recommends that
the City Council ratify a payment to Ferrari for the services required to relocate the
backflow preventer in accordance with Cal Water requirements.
ALTERNATIVES:
In addition to the Staff recommendation, the following alternative actions are available for
the City Council’s consideration:
1. Do not approve the payment to Ferrari Backflow, Inc. for services to relocate a
backflow prevention device on the water line to the new Park, which may result in
Ferrari Backflow, Inc. pursuing legal action because the services were provided in
good faith to meet the requirements of Cal Water and restore water service to the
Park expeditiously.
2. Take other action, as deemed appropriate by the City Council.
