This project includes the renovation of the Old Main Heating Plant building to add combined heat and power generation equipment and space plan for a future package boiler and future chilled water plant equipment to create a multi-function Old Main Utility Building. Originally constructed in 1912, the Old Main Heating Plant has undergone several renovations/additions over the years. It houses seven (7) coal & gas fired boilers, the last of which was shut down from steam production in 2000. Since that time the building has fallen into disrepair. The building also currently houses a steam pipe fitter workshop area and provides key access points to the deep steam tunnels.

Due to both the growth of new University buildings requiring steam service and aging boiler equipment on the Minneapolis campus, the University is at risk for a shortage in firm boiler capacity relative to winter-time peak steam demand beginning in 2014. Therefore, new steam boiler equipment that will provide the additional required steam capacity needs to be added to the Minneapolis campus. This will be accomplished by installing new combined heat and power equipment in the existing Old Main Utility Building located adjacent to the Mississippi river in the Knoll area. The combined heat and power equipment represents a two stage configuration. First a new natural gas fired turbine will generate electricity for use on the Minneapolis campus. Second a new heat recovery steam boiler will recover heat from the combustion gases that are discharged from the turbine to generate the required steam capacity. The combined heat and power equipment solution was chosen because the added benefit of electricity generation for use on campus further reduces the carbon footprint for the University and represents the best long term sustainable solution from an energy use standpoint. Additionally, the plant will be designed with space allocation for future installation of a packaged boiler as well as two steam turbine-driven chillers.

A significant portion of the project budget is devoted to hazardous materials abatement for both the Old Main building and the adjacent incinerator building (which is planned to be demolished as part of this project). The existing boilers and piping within the Old Main building contain significant amounts of asbestos in the boiler and piping insulation. Abatement/demolition of the boilers is also complicated by the fact that the building structural columns were built integral with the boilers. Therefore, some of the building columns will need to be removed and replaced as part of the boiler demolition work. The building exterior walls are in relatively good shape and will be refurbished where required. The building roof profile will be simplified by removal of the multiple penthouses and a new roof will be installed.

Project Status Updates

June 2014

The abatement and interior demolition work progresses is on-going. Prepping work for the east side containment is being finalized, including moving the North-South barrier wall. The retaining wall, which is part of the site work, is on hold and being redesigned.

April 2014

The abatement and interior demolition work on the old main building is on-going and the contractors are making good progress. Site demolition work is moving ahead with excavation scheduled to start April 22nd. Removal of the roof breeching will begin on May 5th.

March 2014

Construction documents and air emission permits are under revision and review; these will be ongoing tasks for the coming months. Options are being considered for the storage of the turbine, and heat recovery steam generator (heat recovery boiler), as to which will be most economical and practical. Appropriate permits have been acquired, or are awaiting review for demolition, and building. Hazardous material abatement work necessary for demolition continues.

February 2014

Construction documents are ongoing. Design coordination is ongoing for the Owner procured turbine/generator and the Owner procured heat recovery steam generator (heat recovery boiler). Hazardous material abatement work along with supporting minor demolition work is ongoing.

January 2014

Construction documents have begun. Design coordination is underway for the Owner procured turbine/generator and the Owner procured heat recovery steam generator (heat recovery boiler). Hazardous material abatement work along with supporting minor demolition work is ongoing.

December 2013

The hazardous material abatement contract has been awarded. The application paperwork for the air emission permit amendment application has been submitted to the state MPCA for initial review. Hazardous material abatement work along with supporting minor demolition work has begun.

September 2013

The Design Development documents are complete.  Further refinement of the design will take place as we move into Construction Documents.  The Owner procured turbine/generator has been purchased and is currently in the manufacturing process.  The Owner procured heat recovery steam generator (heat recovery boiler) has been purchased and is currently in the manufacturing process.  The Owner procured natural gas compressor RFP will be issued soon.  The RFP has been issued for the hazardous material abatement contract.  We are nearing completion of the application paperwork for the air emission permit amendment application and will be submitted to the state MPCA in the near future.

August 2012

The predesign is complete. Further refinement of the design will take place as we move into SD/DD/CD’s. In anticipation of moving forward the following activities are also underway:

  1. Destructive testing of the existing boilers for the purpose of hazardous material abatement planning.
  2. Phase II Level Soil Borings and preparation of the Environmental Response Action Plan.
  3. Geotechnical exploration and materials testing.
  4. High definition laser scanning and 3D BIM modeling of the existing plant.
