SUBJECT: Approve Resolution 4272 authorizing the City Manager to sign Change

MEETING DATE: August 2, 2010
AGENDA ITEM TYPE: Consent
RECOMMENDATION: Approve Resolution 4272 authorizing the City Manger to sign
Change Order #11 for the Lower Yard Vehicle Maintenance and HRDC Bus Barn to install a
shutoff valve for the compressed air line servicing the shop space and the vehicle lift, (CP #25),
$424.60; and remove alternate No. 5 which was the installation of the skylights, a deduct of
($12,200.00). The total for this change order is a decrease of $11,775.40. This is all on the city
side of the project so the credit will be to the city.
BACKGROUND: The equipment used to lift the vehicles for servicing in the shop areas are
powered with air pressure. The lifts are piped with air lines that allow the lifts to be raised and
lowered. Staff has identified some optional equipment that can be added at the work stations that
will increase both the range and efficiency of the service work performed. Some of the optional
tools are also operated with pneumatic pressure. CP #25 will add an additional air valve during
the initial plumbing that will provide locations so that the optional equipment can be plugged
into the main air lines right at the work station. Adding the valve now will be more cost
effective than trying to come back later and add the valve after everything is already plumbed in.
The second portion of the change is to remove an additive alternate that was bid for the project to
add skylights to the building. Alternate number 5 was originally bid and accepted for the project.
From a building maintenance perspective we have experienced problems with skylights. The
slope of the roof and the potential snow loads on the roof has called into question the long term
benefit of the skylights. The recent hail storm damaged most of the skylights that are installed
23
on other buildings. All these factors came together to make the decision to remove the skylights
from the building.
UNRESOLVED ISSUES: No others related to this proposed Change Order.
ALTERNATIVES: As suggested by the City Commission.
FISCAL EFFECTS: The two items on this change order fall under the category of
owner initiated changes. The costs and credit for Change Order #11 will be charged against the
contingency fund for the project. The overall credit will be $11,775.40. This leaves a balance in
the contingency fund of $123,149.50. The summary of activity is shown below.
