District
MEETING DATE: October 5, 2022
TO: Board of Directors
FROM: Neil Kaufman, Water System Engineer
Chad Reed, Water Utility Director
SUBJECT: Award of the State Route 89 Water Main Slip-lining Construction
Contract
APPROVED BY
Brian C. Wright, General Manager
RECOMMENDATIONS:
a) Waive the minor irregularity associated with Advantage Reline not acknowledging
Addendum No. 1 on its bid forms.
b) Award the State Route 89 Water Main Slip-lining construction contract to
Advantage Reline in an amount of $223,537.53, plus a ten percent change order
allowance of $22,362.47 for a total authorization not to exceed $245,900.00.
BACKGROUND:
There is an existing 10" steel water pipe along the west side of State Route 89 south.
This starts at the north shoulder of Donner Pass Road in front of Mountain Hardware and
ends at the Donner Creek Well site at the northwest corner of Deerfield Drive.
This pipe was installed in 1970 and has experienced a number of leaks in the past 10
years. There are currently two active leaks on this pipe that are surfacing. One is just
north of the westbound on-ramp to Interstate 80. The other is south of the eastbound off-
ramp from Interstate 80. This section of pipe provides a loop to customers south of
Interstate 80 and is important in transmitting water into the Donner Lake, Gateway and
Tahoe Donner areas.
The leak that is north of Interstate 80 is located within a casing. Normally, repair of this
leak would involve excavating the ends of the casing, removing the leaking section of pipe
and replacing it with a new section of pipe. Normally, the existence of the casing would
allow for this work to be performed without disrupting traffic. However, the casing at this

location corresponds to the old on-ramp configuration prior to construction of the
roundabouts and the south end of the casing is now located within the pavement section
of the roundabout.
A similar leak occurred in 2005, south of Interstate 80 during construction of the
roundabouts. At that time, the District was able to coordinate with the contractor building
the roundabouts to perform an emergency repair that involved removing and replacing
about 180 feet inside a casing. Both ends of the casing were accessible because traffic
had been re-routed by the construction.
ANALYSIS/BODY:
Given the need to minimize any traffic disruption, staff considered a number of trenchless
rehabilitation options for this section of pipe. A number of contractors and manufacturers
were contacted. Eventually, slip-lining the existing pipe was identified as the only option
that could be accomplished in the fall of 2022.
Contract documents were prepared for this rehabilitation work and bidding began in
September 2022. The bid opening was held at 11:00 am on September 22. Two bids
were received:
TOTAL AMOUNT OF BID
Bidder Location Amount Responsive
Advantage Reline Moorpark, CA $223,537.53 Yes*
Q&D Construction Reno, NV $500,000.00 Yes
It should be noted that Advantage Reline did not acknowledge Addendum No. 1 on its bid
forms. This addendum clarified a minor issue regarding contractor licensing. The District
has encountered this issue in the past and the failure to acknowledge an addendum can
be considered a minor irregularity that can be waived.
The District will have additional expenses associated with this project involving traffic
control and rental of trench shoring. The project will avoid excavations with the pavement
section of SR 89, but they will be in close proximity to vehicle traffic. Traffic control
provisions will be necessary to ensure a safe working environment.

FISCAL IMPACT:
The bid price from Advantage Reline is $223,537.53. It is recommended that a ten
percent change order allowance of $22,362.47 be established for a total authorization of
$245,900.00.
Including an estimated $54,100 of identified additional costs for this project, the total
project cost is $300,000.
The FY22 water capital expenditure budget is $8,290 million and current forecast is
$8.382 million including this project. The forecast spend is $92,000 or 1.1% over budget
and staff notes the forecast includes contingency. FY22 and FY23 pipeline replacement
projects are budgeted to be funded from new debt issuance proceeds of $15.9 million
received in FY22 and staff recommends this project be funded from these new debt
proceeds.
