INFRASTRUCTURE UPGRADES

Project No. 521-20-901

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 will be 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 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 will be 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 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.

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

7. Alternative Systems Considered

a. Tying into Existing Chilled Water System

1. Existing building-wide chilled water loops do not appear to have existing capacity, and it does not appear feasible to connect the new CRAC units to the existing system in most cases. Existing chilled water lines are far from TR locations which could lead to higher construction costs required to route the piping. As well as additional costs to upsize existing piping.

b. Mini-split systems

1. Refrigerant-based mini-split systems may be an option to provide conditioning for small IT/data spaces, however they would require long lengths of refrigerant lines in many cases, and less efficiency when compared to consolidated chillers.

c. Refrigerant Based CRAC units

1. Refrigerant-based CRAC units were deemed to be unfeasible due to the long lengths of refrigerant piping, that often-exceeded manufacturer limitations. It was also determined that stacked TR’s were most efficiently served off larger single chillers rather than multiple smaller air cooled condensing units.

B. Space Coordination

1. Where existing mechanical systems (HVAC duct, VAV units, mechanical piping, plumbing, etc.) are in data spaces, these items will be relocated to the extent possible to be out of the data room space.

Fire Protection Engineering Design Narrative

Life Safety and Fire Code Compliance The Architectural building modifications to house and accommodate the new EHRM system do not change the building construction type classifications, or the building occupancy totals as defined under the IBC and NFPA building and fire codes.

MODERNIZATION (EHRM)

INFRASTRUCTURE UPGRADES

Project No. 521-20-901

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 will be incorporated into this project.

TR spaces are unoccupied accessory use spaces and do not change or affect the occupancy or hazard classification of the building area in which they are located. No architectural modifications are anticipated for the MCR that would impact life safety or fire code compliance. All new work for the EHRM modernization will meet NFPA 101 requirements for existing buildings as determined by the level of work being conducted. The majority of work is anticipated to meet the requirements of either a renovations or modification as defined by NFPA 101 Section 43.2.2.

Areas with the level of work meeting the definition of a modification will meet NFPA 101 Section 43.5 and newly constructed elements will comply with the requirements of NFPA 101 for new construction in accordance with NFPA 101 Section 43.5.1.3. Areas with the level of work meeting the definition of a renovation will meet NFPA 101 Section 43.4 and all new work will comply with the requirements of NFPA 101 for existing buildings in accordance with NFPA 101 Section 43.4.1.3.

Data Center Requirements MCR Room 3431 and PBX Room 3435 are both identified as Telecommunication Spaces (TS) by VA standards.

The MCR is classified as an ITE Room per NFPA 75 Section 3.3.15 and a Campus Support Center by VA Standards with a planned ANSI/TIA-942-B rating of 3 as defined by the VA Infrastructure Standard for Telecommunications Spaces Table 3.

As an ITE Room, the MCR will be provide 1-hr separation from the remainder of the building as required by NFPA 75 Section 6.1.3.4. As a TS, the MCR will be protected by a clean agent extinguishing system in addition to a wet-pipe sprinkler system as required by the VA Fire Protection Design Manual Section 3.7.B. The clean agent system will be provided above and below the raised floor and provide protection within the cold aisle containment.

The PBX room serves as the Entrance Room for the facility and has a planned ANSI/TIA-942-B rating of 1 as defined by the VA Infrastructure Standard for Telecommunications Spaces Table 3. Since the MCR is separated by a 1-hr rated wall from the PBX, it will not be provided a clean agent system. The PBX will be protected by a wet-pipe sprinkler system utilizing standard response sprinklers and smoke detection as required by VA Fire Protection Design Manual Section 3.7.C.

The proposed UPS configuration with the MCR is estimated to provide 35 kWh which does not exceed the aggregate UPS battery capacity noted in NFPA 855 Section 1.3. As such, the requirements of NFPA 855 will not apply to this project.

MODERNIZATION (EHRM)

INFRASTRUCTURE UPGRADES

Project No. 521-20-901

Due to the inclusion of moderate quantities of combustible contents within the MCR and PBX including mechanical equipment, UPS, and a generally higher fuel load, these spaces will be protected as Ordinary Hazard Group 1 in accordance with NFPA 13 Section 4.3.3.

Fire Extinguishers Extinguishers will be provided in accordance with the VA Fire Protection Design Manual and NFPA 10. For telecommunications rooms, clean agent extinguishers will be provided outside of the room, but no greater than 75 feet away. For telecommunication spaces, clean agent extinguishers will be provided inside of the room.

Fire Stopping of Wall Penetrations The contractor will pull a permit on all fire and/or smoke rated walls that require new penetrations. They will also seal any penetrations in rated walls that are abandoned due to work completed for this scope in accordance with a listed penetration assembly corresponding to the appropriate rating of the barrier being penetrated. Permits will be pulled from the New Orleans VA fire department as appropriate.

Fire Detection and Notification As part of the EHRM addition project, any new fire alarm devices will be integrated into and be compatible with the existing fire alarm system. This includes the modules required to monitor the clean agent extinguishing system releasing panel.

Both audible and visual alarms will be provided throughout the new spaces to meet NFPA and VA requirements. Smoke detection will be provided in telecommunication spaces in accordance with VA Fire Protection Design Manual Section 3.7.C and NFPA 72 including MCR Room 3431 and PBX Room 3435.

Fire alarm notification and detection devices will not be provided in telecommunication rooms.

Audio-visual horn/strobe units with combination speaker and flashing alarm strobe will be used. Smoke detectors will be installed (as required) in new mechanical return air ducts in accordance with International Mechanical Code (IMC) requirements and will shut down air handling units upon alarm.

Fire Suppression In accordance with the VA Fire Protection Design Manual, telecommunication spaces will be provided with a wet pipe sprinkler system. Sprinklers will be fusible link sprinklers listed as standard response heads and provided protected cages. A clean agent suppression system will be provided in the Data Center as required by VA Fire Protection Design Manual Section 3.7.B and will comply with NFPA 2001.

Existing and new telecommunication rooms will be protected by the existing sprinkler system and will not be provided with any additional fire protection such as fire rated walls, smoke detection, or a gaseous suppression system. Existing fire sprinklers will be relocated as needed for new ceiling configurations and obstructions in accordance with NFPA 13.
