Description of Location

Minneapolis City Hall/Hennepin County Courthouse


Project Description:

The MBC Mechanical Systems Upgrade includes renovation and upgrade of the heating, ventilating, and air conditioning systems in the Minneapolis City Hall/Courthouse building. These upgrades are being completed based on a 1989 report prepared by Hammel Green and Abrahamson, Inc. The design includes air-handling units, a new ductwork distribution system with VAV boxes, electronic controls, hot water finned tube radiation, exhaust systems for special-equipment hoods and apparatus, restrooms, and restroom exhausts.


The project will upgrade mechanical and life safety systems in approximately 15,000 square-foot sections of the City Hall/Courthouse every six to eight months through the year 2024. The project is being coordinated with several projects including the MBC’s Life Safety Upgrade, removal of asbestos, space reconfiguration and computer infrastructure upgrades by the City and County. The MBC Mechanical Systems Upgrade request includes some electrical non-life safety wiring, plumbing, temporary walls and partitions, and some ceilings and structural components all related to the HVAC systems. Most of the ceiling and general construction components are also completed in the spaces during the project.


Purpose and Justification:

The 1989 engineering study reported the majority of the existing systems were antiquated and undersized, providing inadequate ventilation and poor temperature control throughout the building. In some areas, heating piping is severely corroded and intermittent ruptures have damaged the building and equipment, as well as interrupted work for building tenants. There is concern that many components of the existing system could fail prior to their scheduled replacement. An aggressive schedule is required to replace equipment before it ceases functioning.


The HGA Design Development report identified 20 phases of work. Phasing outlined in this report was modified in 2002 to better allow for work and occupancy of adjoining areas to occur. The first four phases were completed as originally planned. With the addition of the Interior Court areas in 2003, a new construction schedule with 23 stages was developed.


The current schedule anticipates completion of Stages 15 and 19 in years 2020 and 2021 to coincide with City tenant improvements in those spaces, and completion of the final two areas, Stages 20 and 21 in 2023. These remaining Stages - 15, 19, 20, and 21, are considered City space.


In 2014 the MBC participated in the City's Building Energy Challenge and received the program's Achievement Award in 2019. The City Hall/Courthouse building improved energy efficiency and reduced energy related greenhouse gas emissions by more than 15% from 2014 to 2017 and 32% from 2012 to 2016.

Any Prior Year Remaining Bond Authorizations? Yes, but we are planning to spend most of this with the Phase 2 construction and Phase 3 design

projects that are currently in the procurement phase.

Prior Year Remaining Bond Authorizations:


Describe how operating cost increases or decreases were determined and include details such as personnel costs, materials, contracts, energy savings, etc:

Installation of four energy wheels and a chilled water side economizer have been completed. The energy wheels and water side economizer capture energy from exhaust air and utilize that energy to heat, cool, or humidify incoming ventilation air. Originally the outside air intake units were scheduled at the end of the project. They have been rescheduled to capitalize on energy savings and to coordinate construction sequencing issues. Occupancy sensors in the renovated areas keep lighting and air distribution tempered to satisfy occupancy demands. More efficient lighting saves air conditioning expenses.


If new infrastructure, discuss how the department/agency will pay for the increased annual operating costs:

MBC will use operating funding for this. No significant financial impact.


For new infrastructure, describe the estimated timing and dollar amount of future capital investment required to realize the full expected useful life of the project:
