Hilti products will be specified as the Basis of Design. Each new rated penetration will be red in color and marked with its UL label certification number.

LIFE SAFETY AND FIRE CODE COMPLIANCE

TR spaces are unoccupied accessory use spaces and do not change or affect the occupancy or hazard classification of the buildings or the building area in which they are located. All new work for the EHRM modernization will meet existing code; however, there are known compliance issues with existing conditions. In accordance with NFPA 101 Section 43.4.1.4, no modifications will make the existing buildings less conforming with the code.

The Veterans Health Administration Office of Occupational Safety Health (19 HEF) has issued the eighth edition of the VA Fire Protection Design manual, date June 1, 2021. The requirements in this updated manual were incorporated into this project. A portion of manual concerning telecommunication rooms reads as follows:

Per this manual telecommunication rooms (TR) that are provided with wet pipe sprinkler protection as part of the existing building sprinkler system are not required to be provided with any additional fire protection such as fire rated walls, smoke detection, or a gaseous suppression system.

General Storage in Telecommunications Spaces. Paper stock, equipment packed in cardboard boxes, and other combustibles within telecommunications spaces must be restricted to the absolute minimum

INFRASTRUCTURE UPGRADES

Project No. 436-21-700 necessary for efficient operation. Any such materials in these spaces must be kept in totally enclosed metal file cases or cabinets.

For telecommunications rooms (TR) clean agent fire portable extinguishers are being provided no greater than 75 feet away from the IT space on the corridor wall in fire extinguisher cabinets.

Telecommunications rooms are typically locked and are only accessible to IT personnel. Technicians responsible for inspecting fire extinguishers will have more available access if the extinguishers are located outside the locked space.

Per the requirements of NFPA Chapter 19 Existing Healthcare Occupancies, Chapter 39 Existing Business

Occupancies any hazardous area shall be safeguarded by a fire barrier having a 1-hour fire resistance rating or shall be provided with an automatic sprinkler system in accordance with NFPA 101-8.7.1.

Per NFPA 101—2021 39.2.1.4 Means of Egress Requirements:

‘Floor levels that are below the street floor, are used only for storage, heating, and other service equipment; and are not subject to business occupancy shall have means in accordance with Chapter 42.’

Per NFPA 101 Table 42.2.5 Arrangement of Means of Egress:

An ordinary hazard storage occupancy in a non-sprinklered building is limited to 100 ft. for common path of travel, 50 ft. for dead end corridor and 200 ft. travel distance with two means of egress.

By applying the same provisions of NFPA 19 Existing Healthcare Occupancies for Fire Barrier around the new TR with a 1-hour fire resistance rating it is GDM’s opinion and that of our fire protection engineer consultant the TRs meet the intent of NFPA 101 and that of VA’s past interpretations on similar equivalency evaluations.

The design, installation, connection, and testing of a complete condensed aerosol fire suppression system for any unsprinklered TRs shall include, but not be limited to, condensed aerosol generators, fire alarm releasing control panels, automatic alarm initiating devices, audible and visual alarm notification appliances, abort button(s) and manual pull station(s) for suppression release, and any other required devices and connections, including wire and hardware.

The condensed aerosol fire extinguishing system will comply with all requirements of NFPA 2010 and

NFPA 72, except as modified and supplemented by the specification. The system shall be electrically supervised and monitor the integrity of all conductors and connections.

Basis of Design is Hochiki America FirePro Xtinguish or equivalent.

2. Smoke dampers will be provided with integral duct smoke detectors or separately mounted duct smoke detectors. All duct smoke detectors will be addressable type and will be connected to the building fire alarm system.

j. Firestopping

1. All firestopping installation locations will be provided with UL listing sticker.

2. All firestopping shall be red in color

k. Main Computer Room (MCR) Cooling

1. The existing CRAC units (with associated outdoor units) will be reused for cooling and humidity control. The existing units are Liebert Upflow Indoor units with a nominal cooling capacity of 85 kW. The calculated cooling load of the MCR is 80 kW. This meets the VA requirement for N+1 redundancy as either unit can provide the required cooling capacity.

2. The existing CRAC units (with humidification/dehumidification capabilities) will provide cooling & conditioning for the data cabinets in this room in conjunction with a new cold-aisle containment system and updated data cabinet arrangement. The units will be relocated to a room separated from the MCR. New duct work will

INFRASTRUCTURE UPGRADES

Project No. 436-21-700 provide conditioned air to the cold aisle containment system and remove warm air from the hot side of server racks. The units will be linked together using the manufacturer’s controllers and will be configured to operate together in a lead/lag configuration that will also allow concurrent operation at low capacities to maximize energy savings, as well as managing redundancy in the system.

3. Design Criteria:

a. Space conditions will be designed to meet VA HVAC Design Manual & OIT

OEHRM Program requirements (72-81°F temperature range, 30-60% relative humidity, non-condensing).

l. IT/Data Closets (Small Rooms)

1. A dedicated CRAC unit (with humidification/dehumidification capabilities) will provide cooling for these rooms. Use of an independent unit will allow temperature control at all times without requiring the main building conditioning systems

(hydronic loop, VRF units, etc.) to be activated.

2. CRAC units will be provided as single units without any redundancy.

3. In buildings with a single data room, the CRAC unit will have a dedicated outdoor condensing unit. In buildings with multiply data rooms, CRAC units will have indoor water cooled condensers with a single outdoor dry cooler unit to serve all CRAC units.

4. Design Criteria:

a. Space conditions will be designed to meet VA HVAC Design Manual & OIT

OEHRM Program requirements (41-95°F temperature range, 8-80% relative humidity, non-condensing).

2. Ventilation

a. The existing ventilation systems for the building are intended to be re-used and will be re-routed as necessary to accommodate the new room configurations.

3. Hydronic Heating Systems

a. Hydronic heating water system piping will be re-routed as necessary to accommodate the new room configurations.

4. Plumbing Systems

INFRASTRUCTURE UPGRADES

Project No. 436-21-700

a. Existing domestic CW system connections will be provided for CRAC units to enable humidification functions.

1. These connections will be made from the domestic water system.

2. Each water connection to a CRAC unit will be provided with a strainer and isolation valving located outboard of the CRAC unit for ease of maintenance access.

b. Sanitary drain connections will be provided for CRAC units to allow condensate drainage and drainage for dehumidification functionality.

5. Controls

a. The existing Schneider Electric direct digital control (DDC) system that serves the facility will be updated to integrate the new systems and devices provided under this project, as well as mechanical systems that are removed or modified.

b. Each data/IT space will be provided with new space temperature and humidity sensors to enable monitoring of those spaces.

c. The DDC system operates on the VA network with a dedicated subnet.

6. Alternative Systems Considered

a. Mini-split systems

1. Refrigerant-based mini split systems may be an option to provide conditioning for small IT/data spaces, however they would not provide control of humidity levels in the spaces. Due to the environmental conditions in the area, we feel that small CRAC units are a better solution for this reason as they provide specific control of humidity

(including humidification & dehumidification).

b. Underfloor air distribution

1. The existing raised floor system is configured at 6” above the base floor level. Per

CRAC unit manufacturer guidelines, the minimum height of a raised floor system for use as a supply air plenum is 12”. This is intended to allow airflow within the supply plenum without undue obstruction due to cabling and other items that are also routed within the raised floor system. The existing raised floor system will be removed as it does not meet minimum requirements for raised floor air distribution.

STRUCTURAL DESIGN

All new facilities, new additions, and existing buildings requiring major renovations and/or seismic strengthening will be designed in accordance with VA and local Standards for Fort Harrison, MT.

Where applicable, we will verify the load-bearing capacity of the existing structural elements to support the new design loads including all previous renovations. We will review as-built conditions of lateral load resisting systems with respect to ductility and post elastic energy dissipation and deflections.

Where alterations have to be made to the structural elements in existing buildings, these elements individually and the buildings as units, must maintain adequate strength to safely resist both gravity and lateral loads. Any resulting deficiencies will be reinforced accordingly. All structurally modified components will be brought into accordance with current code. Renovations that serve to increase the gravity load on any structural element by more than 5% will be brought into compliance with current code. Renovations that serve to increase the seismic force in any structural element by more than 10% will be brought into compliance with current code. We will evaluate and identify whether or not a full or partial seismic renovation is recommended per codes or VA Design Guides.

The structural concepts and considerations as noted in this 10% BOD shall be evaluated, reviewed, discussed, and confirmed with the COR during the early stages of the project. Concepts shall be developed in sufficient detail to adequately identify the effect on the project program, cost, and schedule with respect to various options.
