CITY OF SHAKOPEE CO~~PIF
MEMORANDUM , . 1 ~'t({V T
To: Mayor and City Council
Mark McNeil, City Administrator
From: Duane Toenyan, Facilities Supervisor
Mark Themig, Park, Recreation, and Facilities Director
Meeting Date: April 17, 2007
SUbject: Professional Services for Design and Bidding of City Hall Air Handling
Unit Replacement
INTRODUCTION
City Council is asked to authorize engineering and consulting services for the
replacement of the rooftop HVAC unit from M & E Engineering, Inc.
BACKGROUND AND DISCUSSION
As part of the 2007 government buildings budget preparation, City Council reviewed a
budget improvement worksheet that details replacing the large McQuay HV AC unit
located on the north end of the roof at City Hall (attached). This unit heats, cools and
provides fresh air flow to approximately half of the building. The age of the unit is
unknown, but has been estimated to be as old as the building (40 years).
Evaluating age, constant repair costs, and poor energy efficiency, we are recommending
that we move forward with replacing this unit. The unit has reached an age where it is
difficult to obtain replacement parts, and last year we had to have a motor mount
fabricated. With improved technology related to greater energy efficiency, some
modifications to ducting in the building will also need to take place along with the unit
replacement. (This will also address airflow problems in various office locations.)
Although the project was discussed during the budget work sessions and Mr. Voxland
indicated that it would be appropriate to fund from the Building Fund, it was not included
in the final building fund project list. However, Mr. Voxland has indicated that the building
fund can support this project.
Proposals
Since the project costs will exceed $50,000, we will need to utilize the competitive
bidding process, and we need professional services of a mechanical engineer to develop
the plans, specifications, and other bidding requirements. M & E Engineering, Inc. and
KFI Engineering, Inc. were consulted and each submitted a proposal for their services:
COMPANY PROVIDED SERVICES COST
. Engineering Design & Construction Documentation
M&E . Bidding
. Construction Administration $10,450.00
. Engineering Design & Construction Documentation
KFI . Bidding
. Construction Administration $14,750.00
RECOMMENDATION
Based on the proposals, both firms offer comparative services with M & E Engineering
having the lower price.
RELATIONSHIP TO VISION
F. Housekeeping
REQUESTED ACTION
If Council concurs, move to authorize an agreement with M & E Engineering, Inc. to
develop plans and specifications for replacing the City Hall McQuay rooftop HVAC unit,
and authorize bidding for this work.

2007 Budget Improvement Package
Instructions - for any improvement that results in an increase of $5, 000 or more, the following
information should be provided:
Project/Improvement:
Replacement of multi-zone rooftop HV AC unit at City Hall.
Prepared by:
Duane Toenyan, Facilities Maintenance Lead
Improvement Description:
Replacement of aging/failing multi-zone rooftop HVAC unit at City Hall.
Description of Need:
The McQuay multi-zone rooftop HVAC unit, located on the north end of the roof, has exceeded
its life expectancy and repair costs to keep it operational are not economically practical
anymore. The unit provides heating, cooling, and air handling for approximately half of the
facility. Heating to the unit is provided with steam from the boiler in the basement. The two air
conditioning compressors located within the unit are deteriorated to a point where they require
constant repairs and have become unreliable, especially when we experience hot weather.
Other items within the unit including: condenser coil, fans/motors/mounts, steam valves, and
electrical components have required many recent repairs. The age of this unit is unknown and
has been estimated to be as old as the building. Maintenance records go back to 1979.
Since there have been many technology changes over the years, an exact replacement unit
doesn't exist; with the exception of a very costly custom made unit. A new replacement unit
would have its own gas fired furnace rather than a steam heating unit to provide heat. This
would relieve some of the demand on the steam boiler, which is also as old as the building and
was suggested to be replaced in the 2000 building study at a cost of $25,000.00. The boiler, at
this point, appears to be in good working condition, but considering age will have upcoming
replacement concerns.
Costs:
All costs to support the improvement (include salary, benefits, training, equipment, and any
other costs). Please identify costs by item:
0183-6315: HAVC unit, installation, parts, electrician, and gas connection $100,000
0183-6312: Engineering and Design Fees $10,000
Anticipated Revenue:
Anticipated additional revenue as a result of the improvement. Please identify additional
revenue by item:
None
Impact on City Service Levels by Funding the Improvement:
Replacement of this unit will provide increased dependability, lower operating costs via higher
efficiency and less service/repair calls, and an improved comfort level at the City Hall facility for
residents, officials, and employees.
