Commission Memorandum
REPORT TO: Honorable Mayor and City Commission
FROM: James Goehrung, Director of Facility Services
Jason Shrauger, Fire Chief
Chuck Winn, Assistant City Manager
SUBJECT: Change Order #007 for Fire Station #3
MEETING DATE: June 22, 2009
RECOMMENDATION: Authorize the City Manager to sign Change Orders #007 in the
amount of $7,829.77, for Fire Station #3.
BACKGROUND: The current schedule for Fire Station #3 and County 911 Emergency
Communications Center, has the Fire Station portion of the project completed by the first part of
July. Change Order Number 007 is for multiple items which are detailed below and have
appropriately apportioned between Gallatin County and the City of Bozeman.
Change Order #007, Part 1, is in the amount of $1,264.00, with all mark-ups. This change
addresses two items.
Two additional recessed lighting fixtures were added in the day room. Now that the layout of the
room is apparent, and the uses have been reviewed by the Fire Department, two light cans were
added in the amount of $354.20.
The second items addresses changes to the material used on the east face of the Fire entrance
tower. The original plans called for this side to be metal siding the other three faces were brick.
The relationship of this tower face to the main roof of the building and the interface with the
brick and the metal siding, had the potential to cause roof problems from winter snow
accumulation. The difference to add the brick, with a credit for the metal is $815.00.

Change Order #007, Part 2, is in the amount of $2,405.77, with mark-ups. This change addresses
5 items.
Item 1: There was a change to the water main connection and some by-passes that were installed
that did not meet code. The change amount of $603.00 is included in the change order. Since
submission the mechanical engineer has agreed to cover the cost of the design oversight. The
engineer will reimburse the city for this amount, by check at a later date.
Item 2: This change includes the relocation of the backflow preventer for the irrigation system.
Because of the screening berm on the east side of the property, the unit was moved inside the
building so that it was out of sight. This costs has since been moved from the city side of the
project to the county. The change was reduced by $401.50.
Items 3 and 4: These changes are related to additional site preparation and additional rebar for
the generator pad and the fuel convault. These two items were owner provided items. The items
were identified in the budget and provisions were made in the design to accommodate them.
Final selection was made based on energy needs and fuel demand. The final selection of the
items required modifications to the size of the pad and the amount of structural rebar that had to
be installed to accommodate the weight and size of both units. The additional site prep was
$425.00 and the additional rebar and placement was $727.00.
Item 5: This change is regarding some ceramic tile in the entry area. During the value
engineering process a modification was made to the entrance. The specifications originally
called for a walk off mat. The mat well was removed from the project and the cost saving put
back in the project. During final pricing the well area was omitted by the tile installer when they
ordered tile. This dollar amount is for the tile and installation of the tile needed to cover the area
of the walk off mat. Price is $470.00.
Change Order #007, Part 3, is in the amount of $4,160.00. This change addresses 4 items.
Item 1: This item deals with the placement of the dryer vent in the washroom. The original
design for a surface mounted metal vent was rejected for aesthetic reasons. The cost for the
change to pace the vent inside the wall is $779.00. The design team will reimburse the city for
the cost of this modification at a later date.
Item 2: This item is for the installation of an upgraded gutter system for the building. The
original gutter was a lighter gage material with a narrow trough. Now that the roof is completed
and some storm surges have been observed, the direction was made to increase the size of the
trough, which means a heavier gauge of metal. The downspouts will also be sized up to
accommodate the increased flow of water. This change will cover the gutters on both the north
and south side of the engine bay area. Cost for this change is $2,298.00.
Item 3: This item is for two gate latches on the service gates on the mezzanine. The mezzanine
area in the fire bays will be used for training purposes and storage. Gates were installed so that
materials could be easily lifted and loaded into the areas. Because of the activities taking place it
7
was determined that for safety purposes a more substantial latch mechanism was needed to
secure the gates. Cost for the modification to the latches is $322.50.
Item 4: This item is for the brackets for the 6 overhead doors in the fire bay area. The doors
brackets attach the door tracks and counterbalance spring to the wall of the building. The doors
tie into an area of the wall in between the garage door opening and the cal-wal arches over the
bay doors. In order to provide a more secure installation of the brackets, additional flanges were
added so that more fasteners could be attached to secure the doors. The cost to modify the
brackets was $448.86.
FISCAL EFFECTS: Change Order #007 will be assessed against the contingency fund for the
project. The contingency for the project is $134,461.00. With all the changes listed to date, and
a full accounting of the construction budget at this time, the contingency balance stands at
$83,858.57. As mentioned above the Mechanical Engineer and the Design Team will reimburse
the city for two items listed in this change order. We will have $1,382.00 credited back to the
project.
ALTERNATIVES: As suggested by the City Commission.
