CITY COUNCIL AGENDA REPORT
MEETING DATE: JULY 23, 2012
AGENDA #: 5K
PREPARED BY: SENG THONGVANH, PROJECT ENGINEER
PRESENTER: SENG THONGVANH
AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION APPROVING CHANGE
ORDER 1 FOR THE BOUDINS PHASE II IMPROVEMENT PROJECT
(CITY PROJECT #12 -011)
DISCUSSION: Introduction
The purpose of this agenda item is to approve a change order and
reduction of construction contract amount for the Boudins Phase II
Improvement Project.
History
At its May 7, 2012 meeting the City Council adopted Resolution 12 -066
authorizing a construction contract with Northwest Asphalt in the amount of
$2,287,195.98. Project construction began on May 29, 2012 and with
favorable working conditions the project is ahead of schedule.
ISSUES: The lowest bid received for the project was over the engineer's estimate.
Due to the higher than expected cost, City Staff and Northwest Asphalt
(lowest responsible bidder) discussed cost saving measures that could be
implemented without impacting City standards. City staff was directed to
move forward with bituminous reclamation to be used as aggregate base
for the project. At that time, the estimated savings was approximately
$50,000. The $50,000 cost savings assumed use of reclaim aggregate
base on the entire project.
Due to the groundwater that was encountered on Boudin Street, it was
determined that use of reclaimed aggregate base would not be ideal.
Instead, Boudin Street from Watersedge Trail to Lois Street would use
crushed limestone aggregate base. Reclaimed aggregate would be placed
from Lois Street to the east of the project on Boudin Street. This change
reduces the savings. The cost savings has been revised to $36,500.70 from
$50,000.
Reuse of onsite material has provided a cost savings as well as reduced
transportation of materials on and off site. Reduction in truck traffic through
the residential neighborhood has also been a positive benefit.
Conclusion
City staff recommends that the change order be approved and the
construction contract revised to reflect the cost savings.
FINANCIAL The use of salvaged material will provide a cost savings of approximately
IMPACT: $36,500.70. The amount will be deducted from the construction contract
with a revised contract amount of $2,250,695.28.
ALTERNATIVES: The alternatives are as follows:
1. Approve Resolution 12 -XXX authorizing change order 1 and reduction
of the construction contract by $36,500.70 to $2,250,695.28 for the
Boudins Phase II Improvement Project (City Project #12 -011).
2. Deny this item for a specific reason and provide Staff with direction.
3. Defer this item until a future date.
RECOMMENDED Alternative No. 1.

INSTRUCTIONS
A. GENERAL INFORMATION
This document was developed to provide a uniform format for handling contract changes that
affect Contract Price or Contract Time. Changes that have been initiated by a Work Directive
Change must be incorporated into a subsequent Change Order if they Affect Price or Time.
Changes that affect Contract Price or Contract Time should be promptly covered by a Change
Order. The practice of accumulating change order items to reduce the administrative burden may
lead to unnecessary disputes.
For supplemental instructions and minor changes not involving a Change in the Contract Price or
Contract Time, a Field Order may be used.
B. COMPLETING THE CHANGE ORDER FORM
Engineer initiates the form, including a description of the changes involved and attachments based
upon documents and proposals submitted by Contractor, or requests from Owner, or Both.
Once Engineer has completed and signed the form, all copies should be sent to Contractor for
approval. After approval by Contractor, all copies should be sent to Owner for approval. Engineer
should make distribution of executed copies after approval by Owner.
If a change only applies to price or to the time, cross out the part of the tabulation that does not
apply.
