TRUCKEE DONNER
Public Utility District
ACTION
To: Board of Directors
From: Joe Horvath
Date: December 02, 2009
Subject: Consideration of the Award of a Construction Contract for the
Donner Lake Transmission Line Pole Replacement Project
1. WHY THIS MATTER IS BEFORE THE BOARD
Board authorization is required for expenditures in excess of$15,000.
2. HISTORY
The Donner Lake Circuit No. 3 feeder is a new 12.47kV distribution feeder that will
originate at the District's Donner Lake Substation and connect to the Tahoe Donner
area. This new feeder circuit is an approved Electric System Master Plan Project for
providing increased electrical capacity and improved reliability. It will be approximately
2 miles long and will be built under existing 60kV transmission lines owned by the
District and NV Energy. Most recently, the Board authorized payment to NV Energy
for the construction of the portion of the circuit to be placed on NV Energy's
transmission line.
The District-owned portion of the 60kV transmission line is approximately 1,500 feet in
length and connects Donner Lake Substation to NV Energy's transmission line. The
installation of the new distribution feeder will require replacement of five existing
transmission poles with larger poles, and the installation of new crossarms to
accommodate the distribution feeder. Construction is difficult because of the steep
sloped area on Donner Lake Road where the poles are located. District crews have
installed 2 of the 5 transmission poles. The three remaining poles are up to 50 feet
away from the road and down a very steep embankment. Access is limited to tracked
excavation equipment. In addition, pole replacement will require a large crane as
District equipment does not have the reach required to replace and set heavy
transmission poles at this location.
3. NEW INFORMATION
A bid package was prepared to solicit bids from qualified contractors for the
installation of three transmission poles and the underbuild circuit. The bid period was
from November 12 to November 20, 2009 and was advertised in the local newspaper.
The District received two bids by the November 20 deadline from Diversified Utility
Services and PAR Electrical Contractors. The lowest bid was determined by a
comparison of total amount bid as submitted on the Bid Schedule. PAR submitted the
lowest bid and was found to be responsive with our contract requirements. The Bid
results are shown on the following table:
Bidder Amount Bid Responsive
Diversified Utility Services $141,723 Yes
PAR Electrical Contractors $67,950 Yes
4. FISCAL IMPACT
The source of funding for the new Donner Lake Circuit No. 3 feeder is Facilities Fees
as this project provides increased electrical capacity and improves reliability. Sufficient
funds exist in the Electric Facilities Fees account to cover the contractor construction
cost.
It is also recommended that the Board of Directors authorize a 10% allowance for
change orders at this time.
5. RECOMMENDATION
Award the Donner Lake Transmission Line Pole Replacement Project contract to PAR
Electrical Contractors in the amount of $74,750 which includes a 10% change order
allowance of $6,800.
