CONSENT
To: Board of Directors
From: Neil Kaufman
Date: March 18, 2009
Subject: Consideration of the Award of Geotechnical 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.
The Water Department has issued a Request for Proposals (RFP) for Geotechnical
Testing Services associated with the 2009 construction projects. The scope of work
covers testing of backfill materials and asphalt associated with the pipeline construction
and modifications to the Tahoe Donner Substation. Also included is testing of concrete at
the Tahoe Donner Substation.
The current schedule for the RFP and contract award is given below:
February 9, 2009 - Issue RFP
March 6, 2009 - Deadline for Submitting Proposals
March 9 to March 13, 2009 - Review Proposals
March 18, 2009 -Award of Contract
3. NEW INFORMATION
Twelve proposals were received in response to the RFP from:
• AMEC - Sparks, NV
• Black Eagle Consulting - Reno, NV
• Converse Consultants - Reno, NV
• Engeo - Rocklin, CA
• Fugro West - Roseville, CA
• Geocon - Carson City, CA
• Holdredge & Kull - Truckee, CA
• Lumos - Reno, NV
• Mactec - Reno, NV
• Marvin Davis & Associates - Reno, NV
• Stantec - Reno, NV
• Wood Rogers - Reno, NV
A staff committee of three members was selected, and the proposals were evaluated
based on the following criteria:
• Project Approach (20%)
• Experience and Qualifications of the Firm (20%)
Experience and Qualifications of the Project Team (20%)
• Local Experience of the Project Team (25%)
• Cost (15%)
• Past District Experience with the Firm (-5 to +5 bonus points)
On a technical basis, all of firms are qualified to perform the testing work and all of the
firms have experience with similar construction projects. AMEC and Holdredge & Kull
were determined to be the top two candidates, followed by a grouping of the
remaining candidates.
The proposed costs were then reviewed. It was found that the firms made a number
of differing assumptions regarding the amount of time to be spent on-site. Using
hourly rates listed in the proposals, a comparable cost was developed for each firm.
The lowest cost was provided by Marvin Davis & Associates with Holdredge & Kull
second and Converse third. The aggregated ranking (capability & cost) of the
proposers:
Firm Rank
Holdredge & Kull 1
AMEC 2
Converse Consultants 3
Stantec 4
Black Eagle Consulting 5
Mactec 6
Fu ro West 7
Wood Rogers 8
En eo 9
Geocon 10
Lumos 11
Marvin Davis & Associates 12
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
from 2006 COP funds and the substation work will be paid from Electric Department
rates.
It is currently estimated that the total cost to the District is $55,000. For comparison,
the District paid about $85,000 to Converse Consultants for Geotechnical Testing
during 2008
The current estimate for funding sources is:
Funding Source Amount
Water Department 2006 COP $51,000
Electric Department Facility $4,000
Fees
Total $55,000
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
1) Award a contract for Geotechnical Testing Services to Holdredge & Kull in an
amount not exceed $60,500.
2) Authorize the transfer of up to $56,100 from COP funds to the Water Department
General Fund and up to $4,400 from Electric Facility Fees to the Water Department
G eral Fund to cover the cost of the contract.
