MEETING DATE: January 6, 2021
TO: Board of Directors
FROM: Neil Kaufman, P.E. Water Engineer
SUBJECT: Closeout of the Tank Site Piping Modifications-2020 Project
APPROVED BY______________________________
Brian Wright, Interim General Manager/
Water Utility Director
RECOMMENDATION:
Adopt Resolution 2021-01 accepting the Tank Site Piping Modifications-2020 project as
complete and authorize the filing of the Notice of Completion.
BACKGROUND:
In May 2020, the Board awarded the construction contract for the Tank Site Piping
Modifications - 2020 project to Longo Incorporated of Tahoe City, California. The project
involves the installation of piping, meter vaults and conduit at six storage tank sites. This
project has two main objectives:
Install valves and bypass piping to allow for future maintenance activities such as
storage tank cleaning, repairs and re-coating as well as pump station valve and
pump replacement without creating a significant impact upon service to water
system customers.
Install meters at selected pump stations to enhance the ability to monitor water
system flows and more accurately identify water loss within specific pressure zones.
This work is needed to comply with forthcoming unfunded mandates from the State
Water Resources Control Board regarding annual water loss audits and data
validity.
The bid price was $292,290. The Board also established a ten percent change for a total
authorization not to exceed $321,500.
Longo began work in June and completed the construction in the December.

During the course of the project, four change order requests were submitted and approved
by District staff for a total of $5,251.47. These items involved:
Two fire hydrant extensions
Changing a 10” gate valve to a 10” butterfly valve due to minimal cover over an
existing pipe
One additional day for the tank diver
In addition to the change order requests, the reconciliation of bid quantities and amounts
actually constructed resulted in a credit of $849 to the District. Attachment 1 shows this
calculation.
In the middle of December, District staff performed a final walkthrough on the project. The
work performed is complete and should be accepted by the District. Attached is a draft
resolution (Attachment 2) accepting the project and directing that a Notice of Completion
be filed.
FISCAL IMPACT:
The original bid price was $292,290. Once adjustments are made for the items described
above, the final contract price is $296,692.47. This total is less than the original Board
authorization of $321,500.
Item Amount
Original bid price $292,290.00
Reconciliation of bid vs. actual quantities ($849.00)
Approved change orders $5,251.47
Total $296,692.47
