Memorandum
To: Board of Directors
From: Neil Kaufman
Date: August 11, 2004
Subject: Construction of the Red Mountain Tank site piping
1. Why this matter is before the board:
Approval from the Board of Directors is necessary to advertise for Bids and to issue a Change
Order to a construction contract.
2. History:
There is an existing water storage tank located off Mt. Judah Drive on the south side of Donner
Lake. This tank is in poor condition and has been out of service since 2001. The tank was
removed from service in 2001 due to fears over a catastrophic collapse of the tank. There is
also a small pump at this site that serves two houses.
As part of the rehabilitation of the Donner Lake Water System, construction of a replacement
tank and a larger hydropneumatic pump station is planned for this site. The new tank would be
slightly larger than the existing tank. The pump station would be sized to serve about 30
houses for both domestic and fire flow demands.
The Board previously awarded a contract to Sauers Engineering for design of the improvements
at this site.
3. New information:
Sauers Engineering has completed the design. There are three major components to the
project.
1) Demolition and removal of the existing steel tank and construction of a new 300,000
gallon tank.
2) Construction of a new hydropneumatic pump station.
3) Construction of a new inlet/outlet pipeline for the tank and a new discharge pipeline for
the pump station.
There are also minor components to the project such as paving, drainage and electrical
conduits. Unfortunately, completion of the design work took longer than anticipated.

Considering that it is now the middle of August, there is not adequate time left to Bid the entire
project as a single contract and have it completed this year.
Therefore, I requested a price proposal from Hansen Brothers (HBE) for construction of the
pipeline work along with associated minor improvements such as conduits and drainage.
Hansen Brothers is currently under Contract to the District for work in the Donner Lath the work
area and
is working on a developer project at the west end of Donner Lake. I am happy
that HBE has performed and HBE has been very conscientious about issues such as clean-up
and erosion control measures that are highly important at the Red Mountain site.
The price proposal for the Red Mountain Take site is $171,778.00
4. Recommendation:
Authorize Change Order No. 1 to the Installation of Services for the North Shore of Donner
Lake—Contract B in the amount of $171,778.00.
