Public Utility District m
MEETING DATE: September 4, 2024
TO: Board of Directors
FROM: Neil Kaufman, System Engineer
Chad Reed, Water Utility Director
SUBJECT: Consideration of Adopting Resolution 2024-15 Accepting the 6170
#2 Tank Construction as Complete and Authorizing the Filing of the
Notice of Completion.
APPROVED BY:
Brian C. Wright, General Manager
RECOMMENDATION:
Adopt Resolution 2024-15 accepting the 6170 Tank #2 project as complete and
authorize the filing of the Notice of Completion.
BACKGROUND:
The Bridge Street 6170 Tank #1 is a 1.5 million gallon, welded steel tank located on
District-owned property. The tank site is north of Interstate 80 and east of Bridge
Street. The access driveway to the site is located on Pioneer Trail, adjacent to the TNT
Materials concrete batch plant.
Tank #1 was constructed in 2002. The site design for the project envisioned the
construction of a second storage tank at the site. The site grading work in 2002
included sufficient space for this second tank, and the site piping included valves to
serve as the points of connection for the second tank. The project description included
in the CEQA review for the project also included the second tank.
At the December 7, 2022, Board meeting, a contract was awarded to Sauers
Engineering to develop the design and prepare contract documents for the second
storage tank. The Sauers contract also included bid phase and construction phase
services.
The contract documents were completed, and advertising for bids began in mid-
February of 2023. The bid opening was held on March 2, 2023, and a construction
contract was awarded to Crosno Construction on March 15, 2023. The bid price for
Crosno was $2,686,720. The Board also established a change order allowance of
$268,680, for a total authorization not to exceed $2,955,400.
ANALYSIS AND BODY:

Page 13 of 72
Crosno completed all the site piping, paving, tank foundation and steel construction
work in October 2023. After completion of the steel construction, the final steps would
be the application of the interior and exterior coatings, followed by disinfection of the
tank. Application of the coatings is sensitive to both temperature and humidity levels,
and takes about 6-8 weeks to complete. Given the time frame (October) and the onset
of winter conditions, it was decided to postpone the application of the coatings to the
summer of 2024.
Crosno remobilized to the site at the end of May 2024 and began the coating
work. The project is now complete and should be accepted by the District. Attached is
a draft resolution (Attachment 1) accepting the project and directing that a Notice of
Completion be filed.
There were six change order requests during the project:
1. As noted above, the grading work associated with the construction of Tank #1 in
2002 included rough grading of the location for Tank #2. Over the past 20 years,
the Water Department has used this area for storage of various soil materials,
piping and equipment. This has resulted in changes to the surface elevation. In
addition, there has been sloughing of soil material off the cut slope on the north
side of the tank pad. The actual pre-construction site elevation was higher than
anticipated by up to two feet in some locations. Removal of this additional
material costs $44,520.00.
2. The project design relied on the original site survey from 2002. Using this
survey, a 117-foot diameter tank with a volume of 2.5 million gallons was
planned. After removal of the excess material noted above, the footprint of the
tank was laid out. It was found that removal of a large rock outcropping on the
west edge of the tank pad would be required. District field personnel also
expressed concern about whether there was sufficient space between the two
tanks for snow removal operations. After considering these two issues, it was
decided to downsize the tank to a diameter of 110 feet with a volume of 2.25
million gallons. This size would allow the access road around the west side of
the tank and provide additional clearance between the two tanks. This
downsizing results in a credit of $54,888.11 for the District.
3. The design drawings for the tank called for installation of an 8" overflow
flow. However, revised calculations during the shop drawing process
determined that this pipe should be 16" in diameter. There is a cost of
$52,925.25 associated with upsizing this piping.
4. The majority of the bid schedule included lump sum/fixed price items. Payment
for asphalt paving work and rock excavation was based on the unit price
bid. The original bid included 6,700 square feet of new paving. This quantity
did not include the removal and replacement of existing pavement required to
run communication and electrical conduits to a panel located southeast of Tank
#1. This required an additional 1,500 square feet of paving at a cost of $22,775.
5. The original bid included 10 hours of rock excavation. However, an additional 58
hours of rock excavation was needed to accomplish the project at a cost of
$61,074.

6. After completion of the final grading and prior to paving, a field inspection was
performed to review the site drainage. It was determined that some
modifications to the site grading and the transition from the access driveway to
the tank pad were needed. After discussion of these issues, a price of
$39,328.28 was agreed upon.
