Sheets AE401 through AE410 document the recommendations on a per-room basis and indicate the architectural modifications need to bring each TR up to standards including:

• Required demolition.

• Replacement of existing flooring with static control (ESD) epoxy flooring.

• Removal of the existing suspended acoustical tile ceiling provides a room clear to the above deck.

Where the room would be open to the interstitial space, a gypsum wallboard hard lid will be provided for security purposes.

• Installation of an 8-foot-high plywood backboard on three walls.

• Updated HVAC.

• Updated telecommunications systems.

An effort was made to obtain the OIT space goal of at least 80 (non-clinical spaces) to

100 square feet (SF) for each TR to support proper access to service existing IT equipment and future replacement efforts of aging hardware. In addition, where TR space redesigns were warranted, the Team focused on minimizing operational impacts to the ALMMVH patient care operations while supporting IT modernization and EHRM upgrades. When a TR did not meet the current space requirements (e.g., at least 80 to

100 SF and a minimum width of 10-feet in clinical spaces), the Team submitted an

Exception Memorandum on March 24, 2023, for the following rooms:

• TR 030, meets area requirement, but minimum width is 8’-7”

• TR F004, meets area requirement, but minimum width is 7’-7”

• TR 105 (to 103.1), meets area requirement, but minimum width is 9’-1”

• TR G101, meets area requirement, but minimum width is 9’-5”

• TR J104, meets area requirement, but width is less than 10-ft

• TR H118.1, meets area requirement, but width is less than 10-ft

• TR P127 (to P125), meets area requirement, but minimum width is 8’-7”

• TR E221, meets area requirement, but width is less than 10-ft

• TR C301.1, meets area requirement, but minimum width is 9’-6”

• TR D320, meets area requirement, but width is less than 10-ft

• TR C402, meets area requirement, but width is less than 10-ft

The Memorandum was signed Concur/Approve on March 28, 2023, by the Capital

Asset Manager and Network Director.

A key decision at 65% Design Development was the scheme for developing a compliant

Data Center. The AE Team proposed relocating the Data Center to the east into the space now occupied by IT Operations, which would provide approximately 1,700 square feet of unobstructed floor area. This allows the construction of the new Data Center while maintaining operations in the current one.

The current Data Center was constructed on the Warehouse roof in 1988, with concrete masonry unit exterior bearing walls and a bar joist roof structure. Subsequent additions to the G-Wing have enveloped this structure. To achieve the minimum height requirement, it is necessary to remove a portion of this structure. A structural engineer has been added to the AE Team to provide recommendations on how to safely remove the bearing walls and roof structure over the new Data Center.

While construction of these areas occurs, a portion of the IT staff will be housed in a temporary modular office (24 feet by 60 feet) placed in the parking lot just north of the

Warehouse. Power and data are already stubbed out to this area.

Detailed layouts for new and existing locations can be found on the drawings included in this package. Refer to Appendix 1.

Telecommunications

Data Center

The existing ALMMVH Data Center in Room I100.1 includes 36 cabinets on a grid raise floor system with cabling routed both above the ceiling, under the raised flooring and across ladder racks in a few locations. The space also includes OIT equipment, Biomedical equipment, and vendor equipment within the room. The equipment racks and cabinets are in rows in a main section of the Data Center but do not meet the hot-aisle-cold-aisle requirement or clearance requirements per the OIT standard. Current infrastructure within the room is OM1 (62.5μ) fiber with some OM3/4 (50μ) fiber optic backbone infrastructure in a single rack with category 6 cabling between the main core switch and the supporting equipment cabinets overhead.

The existing Data Center shall be relocated to the current IT workspace adjacent to

Room I100.2 and will include new server cabinets, all communications, power, and cooling required to meet the VA standard requirements for Data Centers. The IT personnel staff shall be temporarily relocated to a trailer to facilitate the new construction.

The existing Data Center will need to remain active throughout the construction of the project and will require specific phasing and cutover processes. The Core switch row is at capacity and does not meet the OIT standards and will need to be re-worked and may have an impact on the system downtime when re-worked in place. The cutover will require as little to no downtime as possible.

A new Data Center is designed to serve as the hospital’s primary Campus Support

Center (CSC). The new Data Center will include 20 new server cabinets with the addition of an MDA at each row and a row of racks for the main distribution of the fiber throughout the hospital and will include additional cabinets for the main core, security and WAN elements, SPINE, and other major network electronics to support the VA

Hospital. The new Data Center is determined to be the equivalent of a medium Data

Center layout per the OIT standard and will include all telecommunication, power, mechanical and fire stopping per the OIT standards. When the new Data Center is built out, the legacy Data Center will be converted into an office space that will support the

ALMMVH OIT Team. See Appendix 1 for more information on the OIT office space.

Telecommunications Rooms (TR)

A survey of the existing campus TRs determined that many of the TRs need to be relocated or expanded. New or modified TRs will be made compliant with the telecommunications requirements of the OIT standards, with some exceptions/variances. Variances were obtained for certain spaces to maintain current layouts, route cabling between floors (Mezzanine level only), and near complete

ALMMVH projects that may/may not be impacted by this project. Detailed layouts and plans to route new fiber optic cabling can be found on drawings in Appendix 1.

Work areas currently fed by existing TRs that are going to be abandoned in place will be re-cabled to a new TR constructed as part of this project.

There are (6) rooms that are currently under construction that will comply with some of the OIT standards, including category 6a cabling infrastructure, and is being reviewed by the VA and the design team on its compliancy. These rooms will remain in place and will maintain the existing infrastructure and what areas it supports. The improvements will include new backbone fiber optic cabling, revisions to power and cooling, and new bonding.

There will be (16) rooms that are renovated in place to be brought up to the current OIT standards. The new TRs will meet the guidelines set for by OIT in the above referenced standard including new racks, horizontal infrastructure, pathway, grounding, power, cooling, and backbone infrastructure.

There are (11) new rooms that will be used to support the horizontal and backbone infrastructure. The new TRs will meet the guidelines set for by OIT in the above referenced standard including new racks, horizontal infrastructure, pathway, grounding, power, cooling, and backbone infrastructure.

Information Outlet Assessment

As part of the design effort, areas of all buildings served by TRs being renovated, replaced, or fed with Category 5, Category 5e, and Category 6 cable were surveyed to identify outlet locations, cabling quantities, and cabling types. The findings of this assessment are included in the submittal. New Category 6A compliant cable will be installed to existing outlet locations as part of this project.

The building is not planned to switch over to VoIP by the end of this project so each outlet configuration will include (2) Category 6a locations with (2) locations remaining in place that are routed to the voice wall in each supporting TR. These existing cables to remain will require re-termination and testing at the information outlet for the new wall plate configuration.

During the assessment it was determined that all information outlet locations were verified to have a rough-in with a 1” conduit to above the accessible ceiling. There will be some locations that do not have a 1” conduit and have a smaller conduit or no conduit at all. A 1” conduit will allow for a maximum of (4) cables in each box with less in a smaller or no conduit location. These locations will be field verified by the contractor while installing with provisions to add proper pathway for the new cabling requirements.

Fiber Optic Backbone

Per the OIT requirements, new backbone fiber optic cabling will be provided. Each TR in the same building as the Data Center will receive 2X24 strands of OM4 multimode fiber optic cable (24 strands from each core network switch) and 2X12 strands of OS1

(intrabuilding) single mode fiber optic cable. Each TR in the out-buildings will receive

2X24 strands of OS2 (interbuilding) single mode fiber optic cable. The new fiber optic cable will be terminated on LC connectors. The new fiber optic cable with be routed with diverse pathways to a “Core A and Core B” network core switches located in the Data

Center. The two core locations will be separated within the CSC to allow the diverse backbone pathways to be maintained.

Included in the drawings is a plan to route new fiber optic cabling throughout the building. There are some key areas that will need further review due to the routing requirements that may/may not apply to the OIT requirements. This includes a single floor to bridge a section of the building that does not allow for separate routing of the primary and secondary fiber/copper runs. Refer to Appendix 1.

Copper Backbone

Copper backbone is not part of this project. The building will not be switched over to

VoIP by the end of this project and will still have a vast majority of the phone lines as analog. All existing copper infrastructure will remain in place in existing rooms. Each information outlet location will include at least two locations that will remain with two new cables at each location.

New Telecommunications Grounding

A new telecommunications grounding system will be provided for all telecommunication spaces to meet the OIT and ANSI/TIA requirements. Ground bars will be provided in each telecommunication space as per the guidelines.

Telecommunications Phasing

ALMMVH will be operational during the completion of this project. The Data Center, TRs, and telecommunication outlets will need to remain operational throughout the construction process until the new TRs are operational. New horizontal cabling from the new TRs will be fed to the existing outlets as required.

Phasing for cutover to new backbone and horizontal cabling for this project includes:

1. Construct CSC and entrance facility to OIT standards.

2. Construct redundant fiber optic feeds to all campus buildings. Maintain the existing duct banks, tunnels, and existing fiber feeds from the existing Data Center until the end of the project. Install new fiber optic feeds from the Data Center

3. Construct new and expand existing to remain in the TRs. Route new (and redundant) fiber optic from all the newly constructed TRs to the Data Center. Maintain existing TR fiber backbone cabling until the area being served by each respective TR has been re-cabled.

4. Install new horizontal Category 6A cable from new TRs to the outlets. The existing horizontal cable is to remain until new horizontal cable is activated. Old existing horizontal cable will be removed after the new cable is activated.

5. After all new backbone cabling has been installed and terminated, transition network connections to new fiber. After all network connections have been transitioned, the old fiber is to be removed if not supporting other equipment.

6. Any equipment that serves other systems outside the scope of the OEHRM project will remain in place as required based on the information provided. Existing infrastructure and systems will be maintained and evaluated on impact once the rooms have been finalized.

Mechanical

Telecommunication Room Mechanical Infrastructure

All TR fall under the Network Support Center (NSC) space classification within the OIT

Infrastructure Standard for Telecommunications Spaces. Existing rooms being converted to a TR, and existing IT support spaces within the scope of this project not currently meeting the OIT Infrastructure Standard, will have their mechanical systems removed, replaced, or upgraded in order meet the requirements defined in the OIT

Infrastructure Standard for NSC classified spaces.

Each TR will be served by a cooling system. The cooling system will be a DX split system with an indoor wall mounted evaporator and a remote, outdoor condensing unit.

Where practical, multiple indoor units will be connected to a single outdoor condensing unit. Where the refrigerant piping distance and height difference between the indoor and outdoor units exceeds the equipment manufacturer’s limitations, a variable refrigerant flow (VRF) system will be provided. Acceptable equipment manufacturers are

Trane/Mitsubishi, Daikin Applied and LG. Heat load and equipment sizing for each potential TR configuration shall be as follows:

• 1-Rack TR:

o Sensible Heat Rejection: 5 kW/17,060 BTUH o System Size = (1) 2 Ton Split System

• 2-Rack TR:

o Sensible Heat Rejection: 7 kW/23,884 BTUH o System Size = (1) 3 Ton Split System

• 3-Rack TR:

o Sensible Heat Rejection: 8.5 kW/29,002 BTUH o System Size = (2) 2 Ton Split Systems

In addition, equipment shall be sized to maintain air temperature at the inlet of the rack/space temperature between 41°F and 95°F and the space relative humidity between 30% and 60%.

Each TR will be provided with airside supply to achieve pressurization requirements per the VA HVAC Design Manual.

Each TR will be provided with temperature and humidity monitoring integrated into the existing facility Building Automation System (BAS).

Data Center Mechanical Infrastructure

The Data Center falls under the Campus Support Center (CSC) space classification within the OIT Infrastructure Standard for Telecommunications Spaces.

As stated previously, a new Data Center is being constructed in what is the current IT workspace adjacent to the current Data Center. The Data Center rack inlet temperature will be maintained using computer room air conditioning (CRAC) units. Four CRAC units will be provided, sized to provide an N+1 redundancy configuration. CRAC units will be in a downflow configuration and include supply fans with electronically commutated

(EC) motors, a chilled water coil, MERV 8 filtration and supply air turning vanes. The

CRAC units will be mounted 24” above the floor on manufacturer provided floor mounting stands. Return air will be ducted to the rack chimney duct connection and all return air duct will be interconnected among all four CRAC units.

CRAC sizing is based on the following conditions/requirements:

• The total heat rejection at full load is 150kW.

o The at commissioning day one load is expected to be 60kW.

• Each CRAC unit to provide 50kW of cooling capacity for N+1 redundancy.

• Discharge air temperature = 74°F

• Return air temperature = 94°F

• Supply airflow o 4 CRACs running - normal operating condition = 6,000 CFM o 3 CRACs running - one CRAC failed condition = 8,000 CFM

• Expected rack inlet temperature = 74°F - 78°F to meet the OIT requirement of 72°F - 80°F.

The Data Center will be provided with the following monitoring:

• Liquid water detection system at the floor level near CRAC units.

• Multi-location rack cabinet temperature sensors.

• CRAC supply and return air temperature.

These receptacles shall be fed from both the normal and critical branch new TR panelboards. New receptacles shall be provided above the IT racks to serve the technology equipment. New panel schedules shall be provided for each of the new TR panelboards.

Grounding and Bonding System

Proper grounding of existing and new electrical systems will be designed according to the VA Design Manual. Bonding between the electrical systems and the technology infrastructure will be established.

Lightning Protection System

The baseline of this project will be to provide a Lightning Protection System for the existing main hospital building containing the new Data Center. The Lightning Protection

System (LPS) shall be NFPA 780-compliant as required by the OIT.

Metering

Metering will be provided for baseline utility consumption and to show the use of power in TRs over time. The energy consumption data that will be reported will be found in

Table 19 of the OIT standards.

Uninterruptible Power Supply

The existing Data Center is served by two existing UPSs. Each UPS has a rated input voltage of 480V and an output voltage of 480V. “UPS-Data Center” is located within the existing Data Center. “UPS-P” is located in the main switchboard room located elsewhere in the building. “UPS-P” is rated for 80kVA, and its integral meter shows an existing load of 15kVA. UPS-Data Center is rated for 225kVA, and its integral meter shows an existing load of 42.5kVA. Total existing combined electrical load of both

UPS’s is 57.75Kva.

The new UPS system shall consist of (2) new UPS’s that are capable of a maximum battery capacity of 150kVA. But each UPS will initially only be installed with a battery capacity of 60kVA. These (2) UPSs shall provide 2N redundancy to cover 100% of the

IT equipment electrical loads in the Data Center. They are sized to provide a minimum of 10 minutes of back-up capacity and will be provided with a battery monitoring system.

The new UPSs will be fed from a combination of existing electrical switchboards and a new emergency distribution panelboard, both fed downstream by emergency automatic transfer switches. The emergency side of the transfer switch serving each UPS shall be sourced from separate emergency busses. The normal power feeds for the transfer switches will be derived from the existing normal power electrical distribution switchboards with new circuit breakers.

• Calculations – UPS – MCR:

o Per OIT, the ultimate design for the critical load in the generic medium CSC provides for sixteen (16) IT equipment sever cabinets at standard density(5kW) and four (4) at high density (10kW)

(16 x 5kW) + (4 x 10kW) = 120kW o Provide 1.25 of ultimate design load to adequately size UPS

1.25 x 120kW = 150kW (per UPS) o Sizing the UPSs at a maximum 150kVA for future capacity allows the current MCR to facilitate the replacement of up to four standard racks with high density racks in the future.

Lighting

Lighting will be provided for the new rooms to meet OIT and IES footcandle requirements. TR lighting shall consist of 4’-0” LED utility strip light fixtures that will be either chain hung or surface mounted. Lighting will illuminate all aisles and passageways for proper identification of people and equipment. These new light fixtures shall be served from the new TR panelboard.

The new Data Center shall be provided with new lighting consisting of 4’-0” LED utility strip light fixtures that will be chain hung. Lighting will illuminate all aisles and passageways for proper identification of people and equipment. New lighting will be provided to meet OIT and IES footcandle requirements.

Depending on occupancy, three-level lighting protocols will be followed as stated on page 44 of the Infrastructure Standard for Telecommunications Spaces.

HVAC Electrical Connections

New electrical connections shall be provided to all new HVAC equipment.

The TR’s HVAC system shall consist of a DX split system. The outdoor unit shall be served from a nearby existing electrical emergency distribution panelboard. A Nema 3R electrical disconnect shall be provided at each outdoor unit.

Electrical Calculations

Electrical short-circuit, voltage drop, and demand calculations will be performed with computer software. The short-circuit and voltage drop calculations will be calculated with PTW (Power Tools for Windows) SKM. The available fault currents will be gathered, and preliminary calculations will be run for the normal and essential systems being specified. Voltage drop calculations will be performed on feeders and large branch circuits. Voltage drop values will be limited to the National Electrical Code and

VA standards threshold.

Demand calculations for the telecom spaces are prescribed as part of the EHRM and

OIT design standards. These will be followed for demand calculations while considering coincidental loads.

Life Cycle Cost Analysis

The new 150kVA UPSs are considered centralized UPSs. Typical lifetime of a UPS is

10-20 years. Typical factors that affect a UPS’s life cycle cost analysis are environment, usage, maintenance, et cetera.

Fire Alarm

Fire alarm systems will be modified as necessary to accommodate the design. Rework or relocation of fire alarm panels within TRs may be necessary. This may also include new NAC or SLC circuits depending on the relocation of fire alarm panels.

Structural

A structural engineer has been added to the AE Team to provide recommendations on how to safely remove the bearing walls and roof structure over the new Data Center.
