Public Works Facility, Project 08-03: Approve Change Order No.4
Package
PROPOSED MOTION
"The City Council approves Change Order No.4 package in the amount of$7,663.75
for the Public Works Facility.
City Council approval requires a simple majority vote of the City Council present.
BACKGROUND
On February 23, 2009, the City Council approved the plans and specifications and
authorized the ad forbids.
On March 23, 2009, the City Council approved bids for steel and concrete for the facility
and reviewed other bids and quotes.
On April 13, 2009, the City Council approved bids and quotes for the remaining items of
the facility.
DISCUSSION
Staff is requesting Council consider approving changes to contracts for revisions for the
Public Works facility. Included in this request are minor, miscellaneous changes to the
project caused by unforeseen site conditions and requested changes by the Building
Department based upon interpretation of the building code. Also included in this work
are revisions to the office area for security needs. Contract changes like these are normal
for large scale projects and contingency funds were set aside in the budget. The City's
construction manager, RJM Construction, has reviewed the costs and finds them
consistent with current market pricing. The project remains on schedule and on budget.
Below is a brief description of the changes requested:
Revised Pressure Washer and Lube Pipe Revisions
Deduct -$538.00
This item is to delete hardware to the pressure washer and lube pipe design.

Duct Revisions at Mezzanine for Shops
$2,377.39
This addition is for extension of air ducts along with return air drops to the shop based on the Building
Official's interpretation of the building code.
Door Hardware and Security Revisions at Main Exterior Door
$4,098.25
This request is for changes to the security system and electrical contact, power supply and lockset at the
main entrance doors to the offices. The new equipment will be able to communicate with the security
system that is planned for the building.
Deduct for Resinous Coating Allowance
Deduct -$2,000.00
This deduct is for removal of the allowance for a pattern design and color arrangement if the City had
chosen to incorporate a pattern in the floor in the lunch room.
Hallway Ceiling Height Soffit Modification
$613.00
This change was to delete ceiling tile and replace with drywall in the main office hallway. This change
was necessary to fit the overhead utilities in this area.
Revised Countertop in Administration Office Area
$1,777.00
This change.was necessary after review of the office assistant work space location. The new work space
location requested by the office assistant will allow her to view who is entering and exiting the building
better. The new location of the work space requires the countertop to be extended and widened to 30" in
depth.
Exterior Window Revisions at Maintenance and Lunch Room
$1,735.00
This change is to replace the fogged glass with a tinted glass panel that is consistent with other glass panel
windows. These panels were fogged originally because they were thought to need fogging to hide the
wall panels in the interior. The fogged panels do not hide the wall panels very well and should be
changed out to match the other tinted glass.
Air Conditioning Unit AC- L Condensate Piping Revisions
$869.00
This change was requested by the Building Department for removal of the condensation water from the
AC unit in the office meeting room based on building code interpretation.
Relocate Unit Heaters 3 and 4 in the Parks Shop
$1,440.00
This request is to move the ceiling mounted unit heaters to the corner of the parks shop to be out of the
way of the wood working work bench and exterior door.
Delete Pendant Controls for Vehicle Hoists
Deduct -$4,200.00
These controls are used to set the vehicle hoist while the mechanic is at the vehicle instead of at the
control panel. The pendant control has the same controls on a cord that allows one mechanic to position
the hoist in the proper position before lifting a vehicle. These controls can be deleted as long as another
mechanic can help set the hoist as the hoist is raised into the proper position.

Hardware Revisions to Door 105C - Vehicle Maintenance
$749.00
This change is to upgrade the 10ckset and power supply for this door to communicate with the security
system for the building.
Hardware Revisions to Door 115C from the Office Reception Area into the Lunch Room
$940.00
This change is to add a lock and crash bar to this door so no one in the reception area can enter the lunch
room without unlocking the door first.
Utility Shop Office - Paint Precast Ceiling in Exchange of Drop Ceiling Tile
Deduct -$196.89
Total Requested Changes:
$7,663.75
The change order amount is proposed to come out of the contingency amount budgeted for the project.
The project is still projected to be under budget by $413,701.
Since the project is 95% completed staff does not anticipate any more changes to the contracts. The total
amount of changes to the project was less than 2% of the construction contracts. A typical project ofthis
size would see about 5% of the construction contract in change orders. A contractor has a delay claim
into RJM Construction that is requesting for additional groundwater pumping due to a higher than
anticipated groundwater table. RJM is reviewing the claim and will be making a recommendation to the
City about the validity of the claim.
