Commission Memorandum
REPORT TO: Honorable Mayor and City Commission
FROM: Bob Murray, Project Engineer
Rick Hixson, City Engineer
Chuck Winn, Assistant City Manager
SUBJECT: Bozeman Water Reclamation Facility, Digester No. 3 and Solids
Dewatering Building Project – Change Order No. 2.
MEETING DATE: August 22nd, 2011
AGENDA ITEM TYPE: Consent
RECOMMENDATION: Motion and vote to approve and authorize City Manager to sign
Bozeman Water Reclamation Facility, Digester No. 3 and Solids Dewatering Building Project –
Change Order No. 2.
BACKGROUND: Attached is a copy of change order number 2 for the above referenced
project. This change order includes twenty four items. Six of the items are credits while the
other eighteen are additions. Pages two through five of the attached document titled “Change
Order No. 2 Summary” provides a short description of each of the items involved with this
change. Additionally, the remainder of the document contains the detailed backup cost
information for each item.
With the exception of CPR 48, the change order is a wash financially. CRP 48 is an owner
requested change to enclose the sludge load out bay for $150,000. When the overall project was
repackaged and portions rebid, one of the elements that was removed was the sludge storage
building. This was going to be where dewatered sludge was stored through the winter months.
The plan was to dewater the sludge during the summer months and then continue to utilize the
sludge ponds during the winter. The plant staff has analyzed the situation and found that it is
much more cost effective and efficient to dewater the sludge year round and haul it to the Logan
landfill for composting. In order to do this, the sludge load out bay must be enclosed in order to
keep the dewatered sludge from freezing. This item also requires an extension of contract time
of 118 days for substantial completion and 68 days for final completion. No other change in
contract time is being provided with this change. The final recommended increase in cost and
time extension for this change is reasonable and commensurate with the work involved.
UNRESOLVED ISSUES: None
ALTERNATIVES: As suggested by the City Commission.
66
FISCAL EFFECTS: Overall this change order increases the contract amount by $150,187.69
from $5,321,791.10 to $5,471,978.79. This will decrease the contingency on the project from
$442,478.25 to $292,290.56.
