Memorandum
To: Board of Directors
From: Neil Kaufman
Date: September 14, 2004
Subject: Change Order No. 3 for the Donner Lake Pipelines-2004 Project
1. Why this matter is before the board:
Approval from the Board of Directors is necessary to issue a Change Order to a construction
contract.
2. History:
The Board previously awarded the Donner Lake Pipelines-2004 project to Jurin Construction,
On August 4, the Board approved Change Order No. 1 that covered all outstanding issues from
the project start through June 2, 2004.
On August 18, the Board approved Change Order No. 2 that covered all outstanding issues
from June 3 through August 6, 2004.
3. New information:
I am requesting a Change Order to the Contract for issues covered under three general items
that will cover all of the outstanding issues encountered from August 7 through September 3,
2004.
Item 1: A total of 50 hours of rock excavation were performed during the period of August 7
through September 3. Jurin's rate is $450 per hour for an excavator with a rock
hammer and $525 per hour for a rock saw. Jurin is owed $22,125.00 for this rock
excavation work.
Item 2: During excavation of the pipe trench, there were a number of locations where the
trench was involuntarily widened due to the removal of rocks. These locations
require importation of additional backfill material and extra compaction effort. At total
of about 92 cubic yards of excess backfill material was necessary due to this issue
and Jurin is due $9,624.30 for this work.

Item 3: As part of the project, the Contractor is supposed to install risers on a new pole to be a
installed by the District. Due to a miscommunication between the Water and
Electrical Departments, the Electric Department started to install pole on the wrong
date. This created a conflict and stopped the contractor's work until the pole
installation could be rescheduled. Jurin is due $253.25 associated with this delay.
t
Item 4: Unmarked and/or mismarked utilities were encountered at five locations. Jurin is due
$2,496.90 associated with repair of these utilities.
Item 5: As part of the project, the Water Department performed a hot tap of an existing pipe. t
Due to a malfunction of the District's tapping machine, it was necessary for Jurin to
disassemble some assembled pipe to allow the District to tap the pipe a second time. g
Jurin is due $342.83 for this extra work.
Item 6: As the Board was previously informed, there was an issue that arose regarding slash
and braches that were dumped into a wetland area. After on-site meetings with
Scott Ferguson of Lahontan RWQCB, Jurin was directed to perform some
exploratory excavations under the supervision of Glenn Merron to investigate the
hydrology in this area. This work involved a backhoe and operator for 4 hours. Jurin
is due $444.75 for this work.
Item 7: The existing TSD lift station at the corner of Donner Pass Road (DPR) and Summit
Drive was previously fed by a direct bury cable that ran along the south side of DPR.
One component of this project involved installed new conduits to the transformer for
the lift station so that a new cable could be run.
The location of the existing direct bury cable was shown on the Drawings and the
Electrical Department de-energized this cable when the
contractor was working in
the area as a safety measure. The lift station is equipped with a backup generator
and TSD had been informed of the planned work.
One Tuesday evening, the Electrical Department was unable to re-energize the
cable due to a fault. The Electrical Department spent all day Wednesday attempting
to locate the fault with no success. On Thursday, it was decided to pull a new cable
into a 4" conduit that had been installed in 1999 jointly with Southwest Gas and
Williams Communications.
Through a fortuitous stroke of luck, the conduit installed in 1999 ended adjacent to a
newly installed electrical vault. It was necessary to excavate an extra 10 feet of
trench to connect the conduit installed in 1999 to the new vault. Jurin is owed
$1,438.54 for this work.
Item 8: The drawings indicated installation of a fire hydrant on the northeast corner of
Donner Pass Road (DPR) and Summit Drive. However, after installation of the
hydrant
side of DPR. Jurin s determined wed $813.21 associated with that a better location for the relocation wouldrant t
relocationofhis fire
on the
south e
hydrant.

4. Recommendation:
I recommend that the Board authorize Contract Change Order No. 3, in the amount of a
$37,538.78 payment to Jurin Construction from the District.
