U of M Department of Research Animal ResourcesVeterinary Science Cage Washer and HVAC Upgrades Executive Summary


EXECUTIVE SUMMARY

The Veterinary Science Bottle Washer and HVAC Upgrade project consists of fi ve interior renovation projects, one located in the Veterinary Science Building 374 and four located in the Veterinary Medicine South Building 371. The scope of work includes renovating rooms for animal caging and installation of an existing bottle washer.

Project #1Installation of Bottle Washer, Room 345D, Veterinary Science Building 374

There is currently not a dedicated cage washer for the cages located in the Veterinary Science Area 3 vivarium. The Veterinary Science Area 1 washer does not have the capacity to wash cages from both areas, due to the existing quantity of cages, plus the increase in cages from selected animal programs. The existing Steris bottle washer (also used for cages) in Room 345D was relocated to the St. Paul campus from the Academic Health Center’s Research Building Management Services, located at 717 Delaware Street, several years ago. It has not been connected for use since it’s arrival at the St. Paul Campus.

The washer is an electric heated unit requiring 480V, 3-phase, 50-amp power. As Building 374 does not have this amount of power in this area, a transformer is needed in the main electrical room to step up feeder voltage to 480V. Adequate plumbing utilities are available, including adequate supply and drain. An exhaust fan is needed for excess condensate evacuation that vents directly to the exterior of the building.

In the event that the existing washer unit does not function properly upon connection, a second option is being considered that requires the purchase of a new Steris steam-heated washer unit. This unit will fi t within the room in the same location as the existing washer. The power and ventilation requirements are the same as for the existing washer. Plant steam currently serving Building 374 would be utilized, with the supply and return connections running from the washer unit to an existing fl ash tank located within Room 345D. The Energy Management standards for the University of Minnesota for operating this equipment will be met. Note: purchase of the washer is not included in this Project.

Project #2 & #3Renovation of Rooms A357 and A361, Veterinary Medicine South Building 371

Renovation of these two rooms is required as the current confi guration of cages limits the number of animals that can be housed in the room. There is also a potential health and safety hazard created by the cages in their existing locations.

Section 1.0 Page 1

U of M Department of Research Animal ResourcesVeterinary Science Cage Washer and HVAC Upgrades Executive Summary


Renovations include the removal of concrete curbs and installation of new fl oor drains formed in existing trenches along the side walls of each room. The fl oor will be refi nished with an epoxy paint applied over a cementitious underlayment, walls will be patched to match existing fi nishes and a new scrubbable acoustical ceiling tile with new lights and mechanical diffusers will be provided to replace the existing ceiling of the same materials. Electrical work consists of lighting, devices and branch circuit wiring.

All areas disturbed on the fl oor below these two rooms due to the installation of plumbing connections will be patched to match existing conditions.

Project #4 and #5Renovation of Rooms C211 and D201, Veterinary Medicine South Building 371

Renovation of these two rooms is needed to house animals that are being relocated from the Veterinary Science South Building on Level 2. Due to the variety of animals being relocated, the existing rooms need to be subdivided.

Renovations include the removal of concrete curbs and the installation of new concrete block partitions dividing Room C211 into two rooms and Room D201 into four rooms. New prefabricated fl oor drains will be installed in parts of the existing fl oor slab that can be penetrated without compromising the structural integrity of the existing concrete pan and joist system. The fl oor slab removed for the new trenches will be replaced below the trenches with a formed deck and lightweight concrete in quantities that ensure a one-hour-rated fl oor slab. The fl oor will be fi nished with an epoxy paint applied over a cementitious underlayment, walls will be patched to match existing fi nishes and a new moisture-resistant gypsum board ceiling tile with new lights and mechanical diffusers will be provided.

Additionally, new stainless steel sinks and hose bibs will be installed in the new rooms, connecting to existing supply and vent piping. HVAC systems will be modifi ed and/or expanded to serve the new rooms; separate room temperature controls are included.

Power work includes removing existing circuits to the existing air handling unit and providing circuits to two new air handling units for Room C211. Additional work consists of lighting, devices and branch circuit wiring.

Additional Project ProposalInstallation of DDC Controls for Veterinary Science 1st Floor Fan Units 001, 002 and 012 and Veterinary Science 3rd Floor Fan Unit 010

This Project will not be included in the scope of work as additional research is required to determine desired outcomes.

A. Summary

A brief review was conducted with Clayton Talbot, University of Minnesota Plans Examiner to orient the Building Code Division with the scope of work for all the projects. The functions of all the reno-vated rooms will remain the same; the work does not impact current exit paths. All new doors and their associated hardware will be installed to meet accessibility code requirements. All mechanical and electrical work will be performed in compliance with all currently applicable codes as noted be-low. There are no hazardous chemicals used in the renovated rooms.

B. Applicable Codes: - Building Code: 2007 Minnesota State Building Code (2006 IBC with amendments) - Mechanical Code: 2009 Minnesota State Mechanical Code - Plumbing Code: International Plumbing Code and IBC Chapter 29 - 2003 Minnesota State Plumbing Code - Electrical Code: 2008 National Electrical Code - Fire Code: 2006 International Fire Code (Minnesota State Fire Code, Chapter 7510) - Life Safety Code: 2006 International Fire Code (Minnesota State Building Code, Chapter 7510) - 2007 Accessibility Code: ADAAG (Minnesota State Building Code, Chapter 1341) and EEOC Ac-

cessibility Guidelines - 2009 Energy Code: Minnesota State Building Code, Chapters 7670-7678 - Environmental Protection Agency Standards - Minnesota Department of Labor – OSHA Regulations

C. Occupancy and Construction Type: - Building 371: B / H-3 (Classroom, Lab, Offi ce, Lounge, Other) Construction Type: II-A - Building 374: B / A-3 (Auditorium, Classroom, Lab, Offi ce. Lounge, Other) Construction Type: III-A D. University Fire Protection Master Plans

The University is in the process of providing the infrastructure piping for automatic sprinkler systems for Buildings 416 and 427. The University’s plan is to provide this infrastructure for Buildings 371, 385A and 374, dependent upon funding. Per a review of the proposed fi re protection drawings for Buildings 374 and 371, the rooms being renovated in this Predesign document do not fall within the scope of future work for these buildings. Hence, no sprinkler work is being provided.
