REPORT TO: Honorable Mayor and City Commission
FROM: James Goehrung, Director of Facility Services
Chuck Winn, Assistant City Manager
SUBJECT: Approve Resolution 4300 authorizing the City Manager to sign
Change Order #15 for the Lower Yard Vehicle Maintenance and HRDC Bus Barn for
mechanical and plumbing modifications and sub-base improvements for the site road system.
MEETING DATE: November 8, 2010
AGENDA ITEM TYPE: Consent
RECOMMENDATION: Approve Resolution 4300 authorizing the City Manger to sign
Change Order #15 in the amount of $7,536.38, for the Lower Yard Vehicle Maintenance and
HRDC Bus Barn.
The changes include: CP #17 added cost for an ADA compliant shower, $1,112.10; CP #33
additional air supply line for the Mohawk vehicle lift, $1,003.20; CP #35 credit for recirculation
pump on domestic hot water line, ($228.00), CP #38 sub-base road preparation and material for
area near the impound yard, $3,772.78, CP #40 add utility connections for a washer and dryer
hook-up, $1,818.41; CP #41 relocate the fire control panel and install additional pull stations
and smoke detectors, $385.28; CP # 44 change in ceiling height to accommodate roof drains and
mechanical ducting, $110.00; CP #46 credit for the removal of a fire wall that was no longer
needed now that the old wastewater treatment plant building is fully out of use, ($437.39).
BACKGROUND: This change order includes four mechanical and plumbing related items.
CP #17 is for the difference between the standard shower unit that was bid and an ADA
compliant unit. CP #33 is for an additional air line for the supply connection on the Mohawk
vehicle lift. CP #41 is for the relocation of the fire alarm panel into the secure IT closet. The
owners also decided to add some additional pull stations and smoke sensors in other parts of the
building. This change item will be charged against the Pre-Construction Change Order Fund.
CP #44 is to change some of the ceiling heights due to conflicts between some mechanical
ducting and the roof drain lines.

CP #38 is a site related change order. The exit road onto East Griffin Drive is over a portion of
the old Impound Yard. During site excavation the vehicle traffic demonstrated that the road
surface was inadequate. This change is the cost to build up the road base to the standards
matching adjacent road beds, minus the cost to restore the area to its original condition which is
the contractor’s responsibility.
CP #40 is an owner initiated change. The Vehicle Maintenance Department requested the
addition of a washer and dryer for their clothing and shop rags. This change is to add the
necessary utility connections for electrical, water, and venting.
There are two credits included on this change order. CP #35 is for the elimination of the
continuous recirculation of domestic hot water by the use of a pump. This change is for the cost
of the pump. CP #46 is for the removal of a fire wall in the vehicle maintenance bay. A two
hour fire break was required for the adjoining building. That old wastewater treatment building,
also used as a fire training building, is now out of service so there is no need for the 1 hour fire
rating on the wall.
CP #39 is an official date change for the completion of the project. The schedule shows
occupancy on November 18, 2010. The delay was due to the problems with the metal building
manufacturer. The contractor severed the agreement with this sub-contractor and hired a new
firm. The new supplier has lived up to their schedule and we are still on line for the revised
completion date. There are no dollar costs associated with this change proposal. All the
redesign costs were covered by the contractor.
UNRESOLVED ISSUES: None related to the items listed on this change order.
ALTERNATIVES: As suggested by the City Commission.
FISCAL EFFECTS: The costs associated with the items in this change order will be
paid out of the project contingency fund. Through Change Order #15, the current balance for the
Pre-Construction Change Orders is $5,465.62. The balance for the 12% Project Contingency
Change Order is $73,806.03. The summary of activity for the contingency fund is shown below.
