Public Utility District
ACTION
To: Board of Directors
From: Neil Kaufman
Date: April 02, 2014
Subject: Consideration of the Extension of a Contract to Perform
Geotechnical Testing Services
1. WHY THIS MATTER IS BEFORE THE BOARD
Board action is required for expenditures in excess of$15,000.
2. HISTORY
Geotechnical Testing involves testing of materials such as soil, asphalt and concrete
associated with the District's construction projects. The District has a need for such
testing associated with its construction projects and District personnel are not trained
nor equipped to perform the necessary testing work.
In February 2013, the District issued a Request for Proposals (RFP) for Geotechnical
Testing Services associated with the planned 2013 construction projects. The scope of
work covered testing of backfill materials and asphalt associated with the District Pipeline
Replacement - 2013 and Donner Lake Substation Civil Improvements projects. The
RFP stated that the District could choose to retain the selected firm to perform additional
testing work during 2014 and 2015
After review of the proposals, District staff recommended that Holdredge & Kull (H&K) be
selected. The Board then awarded a contract to H&K.
3. NEW INFORMATION
The work performed by H&K during 2013 was satisfactory. District staff requested a
proposal to perform geotechnical testing for the planned 2014 construction projects.
• District Pipeline Replacement-2014
• Donner Lake Substation Civil Improvements
• Spring Street Pipeline Rehabilitation
The cost proposal from H&K for this work is $64,592. Of that total, $58,326 is
associated with the pipeline replacement project and $6,266 is associated with the
substation project.
4. FISCAL IMPACT
Geotechnical testing will be paid on an hourly basis and the hourly cost will allocated
to the project on which the work is performed. The pipeline related work will be paid by
the Water Department and the substation work will be paid by the Electric Department.
It is currently estimated that the total cost to the District will be about $30,000 with
about $23,000 related to the pipeline project and about $7,000 related to the
substation project.
The current recommendation for funding sources is:
Funding Source Amount
Water Department Capital Replacement Fund $58,326
Electric Department Facility Fees $6,266
Total $64,592
Sufficient funds exist from these sources to cover the costs. It is also recommended
that a 10 percent change order allowance be established.
5. RECOMMENDATION
a) Extend the contract for Geotechnical Testing Services to Holdredge & Kull for a base
amount of $64,592 plus a 10 percent change order allowance for a total not to
exceed $71,050.
b) Authorize the transfer of up to $64,150 from the Water Department Capital
Replacement Fund to the Water Department General Fund to cover the Water
Department's share of the contract.
c) Authorize the transfer of up to $6,900 from Electric Department Facility Fees to
the Electric Department General Fund to cover the Electric Department's share of
the contract.
