SCOPE:

The spaces scheduled for remodel under this submission currently house outpatient psychiatric care spaces and an existing previously approved atrium with large planters.

The Outpatient Mental Health Clinic currently houses a number of offices for the providers as wells as admin and support areas such as conference rooms. The expansion project will replace the existing planter area with new group therapy rooms, a new reception area, and new offices for an additional team of providers. Approximately 70% of the existing spaces will be substantially renovated, the remainder will be repainted at a minimum. Existing bathrooms will primarily remain untouched.

ARCHITECTURAL DEMOLITION:

Existing First Floor Atrium: This area will have the existing planters removed in their entirety. Existing planters are a brick masonry construction with a sheet waterproofing liner over sloped light-weight concrete. They contain live plants, soil, and a drainage system.

Additionally, the area surrounding the planters currently has a quarry tile finish, set on a full thickness mud bed (as opposed to a thin-set installation). This tile and mud bed will be removed.

60 East Plato Blvd., Suite 300 | Saint Paul, MN 55107-1831 | tel: 651.771.2222 | fax: 651.209.2893 | Benham.com

The South and East as well as small portions of the West and North walls of the atrium will need to be shored and selectively demolished to allow for installation of the new structural framing and floor slabs. An existing fire shutter on the North wall will be removed. The walls on the NW side of the atrium (walls that extend to create the knee wall for the Surgery Waiting area on the second floor will need to be fully removed. On the first floor, these walls are a curtain wall system.

Existing Outpatient Mental Health Clinic (Area 1-P): Offices adjoining the existing atrium will be removed in their entirety. A selection of the other offices are selectively demolished, including the removal of a number of doors. These doors do not meet the current size or location required by the design. As such those doors and frames will be turned over to the owner or disposed of. Offices that experience partial demolition will have the existing ACT ceiling and flooring removed in their entirety. Existing corridors will have the vinyl wallcovering and carpeting removed in its entirety. Handrail/wall guard units will be selectively demolished as required.

ARCHITECTURAL NEW CONSTRUCTION:

First Floor: Construct a new waiting/reception area with space for 5 reception desks

(millwork construction). Eight new group therapy rooms are added, the largest of which will have large built-in storage cabinets for the storage of supplies. The new reception area will have limited controlled access points into the provider office area. Offices for one new team of providers will consume the South “leg” of the infilled atrium area. The

East ~1/3 off the existing offices are rebuilt per a new layout. A new breakroom is created, as well as (2) staff bullpens and (2) staff conference rooms. One of the conference rooms will be temporarily subdivided using demountable petitions. A number of doors are relocated/removed and the openings infilled. Most existing doors in the project are 3’x7’ doors.

Most new doors will be flush wood doors. However, all cross corridor doors will be wood doors with narrow lite in the door. Doors in the entry to the spaces will be “full lite” wood doors, with light having translucent film featuring a color gradient.

The wall separating the main admin “BizHub” form the reception desk will be full height with a decorative panels inset and back lit. Decorative panels are to decorative resin glass product made my Lumicore or approved equal.

The smoke control zones have been reconfigured. Walls separating the smoke control zones shall be built as or upgraded to 1-hour fire/smoke resistant barriers. All new walls will extend up to the underside of the interstitial slab.

Second Floor: Reconstruct (4) air distribution pilaster to match others already present on the second floor, in locations where the same were removed on the first floor. Rebuild the wall separating the surgery waiting area from the “new” 2nd floor slab area. At this point

60 East Plato Blvd., Suite 300 | Saint Paul, MN 55107-1831 | tel: 651.771.2222 | fax: 651.209.2893 | Benham.com in time, the VA is intending to decorate/infill on the “new” slab area as part of a separate project.

The new interstitial and second floor slabs and their supporting structure shall be of 2hr fire rated construction.

INTERIORS

Interior finishes will follow Minneapolis VA Standards wherever possible. In the event of a new selection is required due to availability or a discontinuation, one will be made with patient comfort, durability and ease of cleaning in mind. All new flooring as part of the scope of work will include a floor leveling compound in the specification as a result of the area being on the concrete slab that potentially has defects in the flatness that require repair.

All areas within the Outpatient Mental Health Clinic, except those that retained their existing floor finish, will receive a new carpet tile floor finish with a 4” vinyl base.

Additional exceptions to that are the new restroom, breakroom and custodial closets.

Those areas will receive ceramic tile (restroom) and VCT (others). An LVT accent in the main corridor in the space and through the waiting room is also provided. Walls in the interior corridors will have a vinyl wall covering wainscot and hand/guard rail. The walls will all be painted in a light neutral color with Egg Shell finish. The lighting will utilize new LED technologies and match that of the fixtures used in the previous project down the hall.

The corridor outside of Outpatient Mental Health Clinic will have a stone veneers wainscot, stainless steel base and hand/guard rail. The entry into the clinic will be clad with wood veneered panels.

New standard signage will be implemented for the rooms affected within this project.

Any furniture shown on the drawings is intended for coordination and intent purposes only. Final furniture plans will be generated by furniture vender in an effort led by the owner.

FIRE PROTECTION SYSTEMS

International Building Code - 2015*

VA Fire Protection Design Manual - 2015

NFPA 72 - 2016 National Fire Alarm and Signaling Code

NFPA 13 – 2016 Standard for the Installation of Sprinkler Systems.

NFPA 101 - 2015** Life Safety Code

**The state of Minnesota currently adopts an amended version of the 2012 IBC.

Note: For design features that are addressed by both the IBC as well as by NFPA 101, the requirements of NFPA 101 shall be used exclusively (this applies even if the IBC requirements are different)

The Mental Health clinic in the Minneapolis VA Medical Center is currently undersized and in need of additional space. The existing Mental Health clinic is located on the 1st floor and the space adjacent to the existing clinic is currently used as a seating area with benches and large planters. The seating area is located on the lowest level (street level) of a 4-story atrium. This atrium space is part of the original building structure built in

1984. The perimeter walls of the existing atrium are comprised of Aluminum curtain wall with metal panels and keyed, operable, non-rated glass windows, creating a smoke barrier classification of the entire shaft from the 1st floor slab to the roof. A passive smoke evacuation system is utilized and is accomplished through the use of motorized smoke hatches located at the roof that open upon smoke detection in the space. The existing atrium space is not sprinkler-protected.

The proposed renovation of the space would remove the seating area and planters on the first level to provide additional offices and training rooms for the existing Mental Health clinic. This renovation will include creating a new “lid” above the existing seating area, at the level of the existing 2nd floor waiting area, reducing the height of the entire space above from 4 stories to 3 stories, open from the 2nd to the 4th floor.

60 East Plato Blvd., Suite 300 | Saint Paul, MN 55107-1831 | tel: 651.771.2222 | fax: 651.209.2893 | Benham.com

OCCUPANCY CLASSIFICATION

Per NFPA 101, the VA Medical Center is classified as a mixed-use building consisting of

Health Care occupancy, Ambulatory Health Care occupancy, and Business occupancy.

The Mental Health clinic will primarily consist of Business occupancy.

Per the International Building Code, the building is classified as a mixed-use occupancy consisting of Institutional Group I-2 and Business Group B occupancies. The Mental

Health clinic will primarily consist of Business Group B occupancy.

BUILDNG ALTERATIONS

NFPA 101 classifies building alterations in different categories of increasing alteration work:

1. Repair - The patching, restoration, or painting of materials, elements, equipment, or fixtures for the purpose of maintaining such materials, elements, equipment, or fixtures in good or sound condition.

2. Renovation - The replacement in kind, strengthening, or upgrading of building elements, materials, equipment, or fixtures, that does not result in a reconfiguration of the building spaces within.

1st Floor

2nd Floor

3rd Floor

4th Floor

60 East Plato Blvd., Suite 300 | Saint Paul, MN 55107-1831 | tel: 651.771.2222 | fax: 651.209.2893 | Benham.com

3. Modification - The reconfiguration of any space; the addition, relocation, or elimination of any door or window; the addition or elimination of load-bearing elements; the reconfiguration or extension of any system; or the installation of any additional equipment.

4. Reconstruction - The reconfiguration of a space that affects an exit or a corridor shared by more than one occupant space; or the reconfiguration of a space such that the rehabilitation work area is not permitted to be occupied because existing means of egress and fire protection systems, or their equivalent, are not in place or continuously maintained.

5. Change of use or occupancy classification - A change in the purpose or level of activity within a structure that involves a change in application of the requirements of the Code, or the change in the occupancy classification of a structure or portion of a structure.

6. Addition - An increase in the building area, aggregate floor area, building height, or number of stories of a structure.

As previously mentioned, the scope of this project is to expand the existing mental health clinic on the first floor of the hospital. The expanded portion of the clinic will encroach into the first floor of the existing 4-story atrium. Based on the level of rehabilitation, this project will be classified as a “modification” and a “reconstruction” project.

The requirements in the code for “reconstruction” projects must also comply with the requirements for “modification” and “renovation” projects. NFPA 101 Section 43.5.1.3 states that:

“Newly constructed elements, components, and systems shall comply with the requirements of other sections of the code applicable to new construction.”

In other words, any newly constructed portion of the mental health clinic shall comply with requirements applicable to new healthcare and business occupancies. Therefore, since the remaining portion of the atrium will not be rehabilitated, the atrium will not be brought up to new codes. Additionally, it should be noted that the renovation work on the first floor will not adversely affect the atrium with regards to fire protection and life safety.

For example:

1. The planters on the first floor will no longer be within the atrium so the fuel load inside the atrium will be reduced.

2. The egress from within the atrium will remain unaffected

60 East Plato Blvd., Suite 300 | Saint Paul, MN 55107-1831 | tel: 651.771.2222 | fax: 651.209.2893 | Benham.com

3. Fire suppression in the atrium will remain unchanged. The 1981 edition of NFPA

101 did not require sprinkler protection in atriums where the ceiling is greater than 55 feet above the floor. Once the mental health clinic is added to the first floor, the new floor to ceiling height will still be greater than 55 feet.

Any upgrades to the atrium are not explicitly required by the code, so any atrium upgrades are considered outside of the scope of this project.

FIRE SPRINKLER:

The existing mental health clinic is protected with a wet-pipe automatic sprinkler system.

Sprinkler heads in these areas are of the “institutional” type. The atrium area on the first floor does not have sprinkler protection since it was not required at the time of original construction. Fire hose valves are provided throughout clinic in various locations. The feed main for the fire hose valves come from an adjacent zone.

The scope of work for this project will affect two different sprinkler zones: Sprinkler

Zone 40 and Sprinkler Zone 41. These two zones are served by a dedicated 4-inch control valve assembly located in the interstitial space adjacent to Stair 10. Sprinklers within these zones will be relocated based on the architectural renovations.

Existing Sprinkler Zones

60 East Plato Blvd., Suite 300 | Saint Paul, MN 55107-1831 | tel: 651.771.2222 | fax: 651.209.2893 | Benham.com

The image above shows the new architectural floor plan with the zone boundaries. The existing zone boundaries are indicated by the dashed line, and the new zone boundaries are indicated by the color orange (new Zone 40) or teal (new Zone 41). Sprinklers within several offices will be re-zoned based on the image above. The majority of Zone 41 will be demolished to accommodate the expansion of the mental health clinic into the atrium.

Any impairments to the sprinkler system during construction will be coordinated with

Building Management and the local Fire Department.

FIRE ALARM:

The existing mental health clinic is protected by a Gamewell FCI fire alarm system.

Notification appliances include clear-lens strobes and fire alarm horns. Fire detection is provided via the heat sensing element in the sprinklers. Smoke detection is provided via spot-type smoke detectors located throughout all rooms and common spaces. The scope of work for this project will affect three different smoke control zones (SCZ): SCZ 1-27, 1-28, and 1-34 (atrium).

The smoke control zone boundaries will be rearranged based on the renovation work.

SCZ 1-34 will be elimianted from the project and replaced by SCZ 1-28. The address to any fire alarm equipment within the affected zone boundaries will be reprogrammed accordingly. All new mental health areas will be provided with smoke detection, and occupant notification.

Any impairments to the fire alarm system during construction will be coordinated with

Building Management and the local Fire Department.
