FROM: James Goehrung, Director of Facility Services
Chuck Winn, Assistant City Manager
SUBJECT: Approve Resolution 4313authorizing the City Manager to sign Change
Order #21for the Lower Yard Vehicle Maintenance and HRDC Bus Barn. The Change
Order is for an electrical item and three items to address snow melt and run-off from the roof.
MEETING DATE: April 25, 2011
AGENDA ITEM TYPE: Consent
RECOMMENDATION: Approve Resolution 4313 authorizing the City Manger to sign
Change Order #21 in the amount of $10,706.05, (City of Bozeman portion), for the Lower Yard
Vehicle Maintenance Building and HRDC Bus Barn.
This change includes a Change Proposal for electrical modification, and 3 Change Proposals to
address snow melt from the roof and ice build up on the ground near the building entrances.
BACKGROUND: The new Vehicle Maintenance facility is in use by the city. We are
working with the Contractor and Architects to clear up all of the final punch list items and other
issues that have been identified since the city has take over operation of the facility.
Change Proposal #56 is to address a change in the designated voltage for the overhead crane.
The specifications were change from 220 volts to 440 volts. The change required the addition of
a transformer for the increased voltage. The higher voltage will increase the power of the crane.
The change includes a concrete pad that was incorporated into the exit pad for one of the
pedestrian doors. There were also some bollards installed to protect the transformer located on
the northwest corner of the building. Total cost for all these components is $5,273.36.
Change Proposal #71 is to add heat tape to the roof gutters. The roof lines are sloped to the
center office area in order to facilitate the collection and reuse of the snow melt and storm water
for the wash bay facility. Based on the winter conditions we have experienced since taking
occupancy, there is excess snow and ice accumulating in the gutters. When the snow or ice
melts any run-off falls down onto the entrance pads of the building. The solution was to add heat
51
tape in the gutters in order to keep them clear so that they can drain properly. The heat tape for
the gutters on the four corners of the office area will cost $1,557.53.
Change Proposal #75 is to modify the entrance canopy on the south side of the building to divert
any storm water or snow melt off of the main sidewalk. The work includes some addition metal
on the front and side of the canopy and a downspout to divert the run-off into the landscaping
bed when it can drain. Cost for this work is $2,520.85.
Change Proposal #76 is to install heat tape on the east end of the building. Again the winter
conditions have resulted in run-off from the roof on the east side of the building. The west winds
and the snow loads were producing a cornice on the east wall. The snow fence that was installed
has helped control the large clumps of falling snow but when the gutters fill with snow and ice
the run-off causes icing problems on the ground. The installation of the heat tape along the east
wall is priced at $1,354.31.
UNRESOLVED ISSUES: The Contractor has been provided with a list of items that need
attention as warranty items. I have requested a schedule from the Contractor outlining when
each of the items will be taken care of. No costs will be associated with these repairs.
The exterior painting is a contract item that needs to be completed. This work is weather
dependent and will take place once we get predictable warmer weather. Money has been held in
retention until this contract work is complete.
There are two proposed change orders that were denied. There has been no formal word from
the Contractor as to how they might respond.
We are still waiting for pricing on paving the balance of the site. Once we get a number we will
assess the budget and if we have enough process a change order for site paving.
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 #21, the current balance for the
Pre-Construction Change Orders is $5,465.62. The balance for the 12% Project Contingency
Change Order is $19,765.25. The summary of activity for the contingency fund is shown below.
