Public Works Facility, Project 08-03: Approve Change Order No.5
PROPOSED MOTION
"The City Council approves Change Order No.5 in the amount of $23,462.00 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 for bids.
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. 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 Com;truction, 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:
Roof Ladder - Vehicle Storage Roof to Vehicle Maintenance Area
$3,170.00
This item is requested by the building officials based upon interpretation of the building
code for access to separate roof elevations.

Bench in Men's Locker Room
$395.00
This item was requested by the building officials based upon interpretation of the building code for
handicap requirements.
Casework Modifications in Multi-Purpose Room
$1,553.00
This item is requested to construct a cabinet around the dishwasher. Originally the dishwasher was
planned to go directly next to the sink. However based on the building official's interpretation of the
building code and handicap accessibility, the countertop in this area needed to be lower. A smaller
handicap countertop height dishwasher was considered, butthis unit is very expensive and was found not
to work as well as the standard size unit. The plan is to add a cabinet unit for the dishwasher on the end
of the south wall.
Upsize an Expansion for the in Floor Heating Unit
$1,278.00
The expansion tank that was originally specified in the contracts was found to be too small for design.
This cost is to exchange the smaller tank for a larger tank which includes the installation cost. The
smaller tank would have caused the system to not run as efficiently and cause premature wear on the heat
pumps.
Add Drop Receptacle in Utility Shop Room 111
$640.00
This item is to add a drop electrical outlet in the utility shop over a work bench. The work bench area is
used to work on hydrants, pumps and other mechanical utility equipment.
Add Manual Switches for Vehicle Exhaust Fan
$640.00
The vehicle exhaust fans were equipment with an on/off switch in the hose reel system. The system is
currently wired so when the hose reel is extended the fans would always be on. This change would add a
switch to the three exhaust fans so they can be turned off and on no matter if the hose reel is extended or
not.
Soil Crrection, Dewatering and Delay Claim for Fuel Tank Installation
$15,086.00
This item is for extra work incurred during the construction of the underground fuel tanks. A change in
conditions at the fuel tank construction area was experienced by the Griggs Contracting, Inc. The water
table was higher than expected based on the soil borings. More soil correction or foundation bedding was
needed for the tanks then what was estimated in the contract documents. Additionally, a delay in
construction was needed to figure out what the right course of action should be based on the tank
manufacturer's recommendations. Originally, Griggs Contracting, Inc. requested over $27,000 in extras
for this work. The City and RJM Construction reviewed the request and reduced the request by what was
documented and reasonable.
Total Requested Changes:
$23,462.00
The change order amount is proposed to come out of the contingency amount budgeted for the project.
The project is estimated be under budget by $471,800.00.
The work left to be completed is paving the parking lot wear course in the spring and some landscape
work. Since the project is 99% completed, staff does not anticipate any more changes to the contracts.

The total amount of changes to the project was less than 3% of the construction contracts. A typical
project of this size would see about 5% of the construction contract in change orders.

RE: ChanhassenPublic Works
Griggs Contracting Change Order Request dated 10-13-09
Dear Chauncey,
RJM has reviewed Griggs Contracting claim based on our meeting. December 21, 2009.
The following is a revision to the true costs based on our meeting and RJM's continuing
research and investigation.
The Costs Associated With The Delay
Between July 6,2009 to July 10,2009, the claim was that Griggs was on hold~ The
only activity that would be occurring is the dewatering. At the meeting on December.
21, 2009, Griggs stated that two men came to the site in anticipation of continuing work
eachday. RJM Construction's superintendent noted Griggs on-site for less than four
hours a day during this ~e period for a total of 40 hours x $SOlhour = $3,200 plus
equipment costs as listed for $655.
At the meeting on December 21,2009, Griggs noted that a dump truck and skid loader
were on site as well. ~ determined a one week's rental on a 5 yard dump truck to be
$550/wkand one week's rental on a Bobcat 8185 skidsteer to be $423/wk based on
rental rates at a local rental company. This adds $973 to Griggs Contracting's claim.
The total true value of this claim is $4,828.

At the meeting on December 21,2009, Grigg's noted that the crew worked overtime to
set up and take down pumps and hoses. Add overtime premium to 16 hours of work is
$40 x 16 hours = $640.
The total tnie value of this claim is $3,678.
Soil Correction Costs
No change was made to the claim value for the soil correction costs. The total true
value of this claim is $6,580.
The grand total true value of all the claims is $15,086
RIM Construction will submit these three claims to the Owner and Architect for their

.initial conversations that dewatering would have been required.
