ACTION
To: Board of Directors
From: Sanna Schlosser
Date: July 15, 2009
Subject: Consideration of the Award of a Construction Contract for the
Tahoe Donner Substation Rebuild Project
1. WHY THIS MATTER IS BEFORE THE BOARD
Board approval is required for expenditures in excess of $15,000.
2. HISTORY
The District is rebuilding the Tahoe Donner Substation to improve coordination with
the adjacent transmission line, improve protection of our equipment, and provide
compliance with current code requirements. The District awarded the engineering
contract for this project in November 2007. The equipment purchase contracts were
awarded in December 2008. Engineering design was completed by the consultants in
May 2009. The bid period was from June 3 to July 1, 2009.
3. NEW INFORMATION
The bid opening for this project was held at 2:00 PM on July 1, 2009. Three bids were
received. A summary of the bids is given below:
Bidder Location Revised Bid Price
PAR Electrical Contractors Reno, NV $622,247.70
NAES Power Contractors Hillsboro, OR $635,696.90
System 3 Carmichael, CA $778,000.00
At the time of bid opening, the apparent low bidder was NAES Power Contractors with
a bid of $612,192.00. However, upon reviewing this bid, two mathematical errors
were identified. After correcting these errors using the procedures described in the bid
documents, the bid total from NAES Power Contractors was revised to $635,696.90.
The bid from PAR Electrical Contractors had a minor irregularity regarding the
acknowledgement of Addendum No. 1 and a minor mathematical error which did not
affect the total bid price. The bid from PAR was then determined to be the lowest
responsive bid.
Construction will take place over two years. The work to be done this year includes
replacing existing underground feeder getaways from the substation and installation of
the new control enclosure. The balance of the work will be performed in 2010.
4. FISCAL IMPACT
The FY 2009 Capital Budget includes $605,314.00 for this project, funded by rates.
Expenditures anticipated for 2009 are approximately $160,000.00. The balance of the
funds and costs for this contract will be included in the FY2010 Capital Budget.
Additional costs will be incurred associated with construction inspection,
environmental compliance and geotechnical services. It is also recommended that the
Board of Directors authorize a 10% allowance for change orders at this time.
5. RECOMMENDATION
Award the Tahoe Donner Substation Rebuild-2009 Contract to PAR Electrical
Contractors in the amount of$684,247.70 which includes a change order allowance of
10%, or$62,000.
