BOARD OF COUNTY COMMISSIONERS
REVIEW/ WORK SESSION REQUEST
RE: CTL Thompson Contract Work Order 7 for misc. testing and new pay rate schedule for 2009.
DEPARTMENT: WELD COUNTY PUBLIC WORKS DATE: February 26. 2009
PERSON REQUESTING: Josh Holbrook, Weld County Public Works.
Brief description of the problem/issue:
Change Order No. 1 - The original agreement for Professional Services under the On -Call Geotechnical
contract could extended from June 18th, 2008 to June 17th, 2009 as permitted by the contract. This extension
would be in the second year of the four year term limit. The 2007 rate Schedule of the original contract would
be replaced with the attached Exhibit A, 2009 Rate Schedule. The increase does not exceed the Denver Boulder
CPI per the contract requirements.
Work Order No. 7 — This work order is set up to cover the testing for the 2009 construction projects that our
lab dose not have the capabilities to perform. We have selected CTL Thompson to perform theses services
under the On -Call Geotechnical Contract. This work order will not exceed $7,500.00
—What options -exist for the Board? 41nclude..consequ n impacts, costs, etc. of options)
BOCC can either approve Work Order No. 7 and the Change Order No. 1 and continue proceeding with the
work or deny approval for Work Order No. 7 and Change Order No. 1.
Recommendation to the Board: I recommend approval of Work Order No. 7 and Change Order No. 1 for CTL
Thompson under the On -Call Geotechnical Contract.
