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.

Project Cost Breakdown

Department Funding Request


Have Grants for this Project been secured? No


Describe status and timing details of secured or applied for grants or other non-City funding sources:

The project is coordinated with the Hennepin County Capital Funding program. By agreement, both City and County Capital Programs must fund the project on a dollar for dollar basis for the project to proceed.

In 2013, a Minnesota Historical Society 2014 Capital Grant was awarded in the amount of $75,000. Grant funds were used to offset the cost of finishing system controls updates in previously finished Stages 1 -4.

Describe any collaborative arrangements with outside project partners, including who they are and what their role is with the project:

The project is coordinated with Hennepin County Capital Program throughout the five year capital funding cycle.

City facility management staff are collaborating on office reconfigurations to improve space allocation efficiencies. Other upgrades including plumbing, electrical, lighting, and communications infrastructure upgrades occur during each stage. For efficiency and coordination with City tenant improvement work, life cycle upgrades and improvements including painting, ceiling tile, and carpet have also been incorporated into the MBC life safety/MEP projects.

This project receives a dollar for dollar match with Hennepin County Capital Funding.


State Law Chapter 462.356 (Subd. 2) requires review of all capital improvements for compliance with the comprehensive municipal plan. Chapter 13, Section 4 of the City Charter requires Location and Design Review for the purpose of approving the sale of bonds for these projects.

Operating Impacts

Operations & Capital Asset Maintenance:

Is this request for new or existing infrastructure? Existing

What is the expected useful life of the project/Improvement? 30

Year that Operating Incr/(Decr) will take effect? 2022

What is the estimated annual operating cost increase or (decrease) for this project? $(20,000)

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:

Project Coordination

Describe completion status for ongoing projects and how and when the department/agency plans to use the prior year remaining bond authorizations:

Schedule for the remaining four Mechanical/Life Safety (MLS) Stages (Stages 15, 19, 20, and 21):

Phase 1 (Stage 19) and Phase 2 (Stage 15) Design: Complete

Phase 1 (Stage 19) Construction: 2021

Phase 2 (Stage 15) Bidding, Procurement and Construction: 2021

Phase 3 (Stages 20 and 21) Design: 2021

Phase 3 (Stages 20 and 21) Bidding, Procurement, and Construction: 2022 - 2023

If this is a new project, describe the major project phases and timing anticipated for completing the project:

Scalability/Funding Allocation Flexibility – discuss any flexibility to increase or decrease funding among the years in the five-year plan and the most that could be spent in a given year:

In conjunction with the City's new Public Service Building and expiring City leases, various offices in the City Hall/Courthouse including the Stages 19,

15, 20, and 21 areas, are being planned for restacking. MBC and the City are working in partnership to complete the Life Safety and Mechanical Stagework and office re-stacking. The project is being phased to meet available funding and the City's occupancy schedule. As outlined in

the previous section, the MBC's 2021 work is being funded with available capital funds, and the Life Safety and Mechanical capital budget request for

2022 will fund the remaining bidding, procurement, and construction work to complete the Stagework.
