5.1 HVAC System

5.1.1 Each Telecommunications Room (TR) will have a ducted 3‐ton chilled water fan coil unit, except TR B236, to maintain space temperature. TR B236 will have a 1‐1/2‐ ton fan coil unit. Each fan coil will have a digital thermostat/controller with display showing room temperature and humidity. These fan coil units will not have humidity control per OIT Infrastructure Standard for Telecommunications Space.

5.1.2 Fan coil units will be located outside of small TRs to avoid the potential of leak either from the chilled water pipes or clogged condensate drain directly over the IT equipment. Fan coil units will be located inside a large TR where these fan coil units can be installed away from the IT equipment.

5.1.3 OIT Infrastructure Standard for Telecommunications Space classified TR as Network

Support Centers (NSC). Per OIT Standards section 3.1.3.11, water detection monitoring is not required. Under current system design, a point water detection system will be provided to monitor the secondary drain pan should the primary condensate drain fail.

EHRM Infrastructure Upgrades Design Narrative

The water detection system will be tied into the Building Automation System which allows on site building engineer to correct deficiency.

5.1.4 The 2‐pipe fan coil units will tie into the building’s existing chilled water loop, which is located in the Mechanical Rooms on each floor; only the fan coil unit on the first floor will tie into a chilled water riser, which is located outside of a Mechanical Room.

5.1.5 Supply and return air will be ducted from fan coil unit. The return air grille will have a filter frame capable to house a standard 20”x20”x1” filter.

5.1.6 Overhead pressurized and non‐pressurized pipes are shown on drawing M401. Drip pans will be installed below these pipes and drain to TR room entrance.

5.1.7 Building air conditioning system will be used to provide positive pressure for all TR rooms. Small TR rooms will have 3 air change per hour (ACH) and large TR room will have 2 ACH.

5.2 HVAC System Capacity

5.2.1 The fan coil unit size will be based on two CyberPower 3 KVA/2.7 KW UPS power output which IT equipment are required to operate. Provide IT equipment heat rejection data, if possible, for an accurate heat load calculation.

5.2.2 Based on the 1988 HVAC record drawings, the existing chilled water plant is capable of providing 1660 GPM of chilled water and the building is using 1312 GPM. The total chilled water consumed by the new fan coil units will be 42 GPM, well within the maximum capacity of the chill water plant.

6. PLUMBING

Provide proper grounding for the new telecom system for the project.

7.2 Existing Telecom Rooms

7.2.1 Minimum Point of Entry (MPOE): MPOE room P201 is located on P2 level of the building, which receives Outside Plant Cables (OSP) from service providers for the building. Fiber optic cables are routed through 24‐inch wide ladder trays in the room to upstairs to the Main Computer Room (MCR) A114 on the first floor. The backbone cable connection between the MPOE and the MCR will remain to reuse for this project.

7.2.2 Main Computer Room: The Main Computer Room A114 is located on the first floor and the whole room is covered by a raised floor with floor tiles. With field measurement, clear space from top of concrete floor slab to bottom of raised floor tiles is about 11" and the floor tile is approximately 1" thick. Each floor tile is supported by pestels at four corners of the tile.

Six 2‐post data racks are installed in the room, which include two separate racks for telecom service equipment from service providers, AT&T and Time

Warner, respectively. The remaining data racks accommodate network

EHRM Infrastructure Upgrades Design Narrative equipment (i.e. fiber splice boxes, core switches, voice gateways, and wireless

LAN controllers, etc.).

Both vertical and horizontal cable management rings were observed on the data racks. However, most of the cables are not run in horizontal management rings so they are not well organized, when routed from the racks to conduit sleeves above the racks to space above the suspended ceiling.

Conduit sleeves above the racks are used to route fiber optic and horizontal cables from the data racks to space above the suspended ceiling.

Both ladder tray and mesh tray are used to run cables above the data racks.

A double section UPS with battery cabinet and 2‐section UPS electrical panel

“UPS‐P1” and “UPS‐P2” serve the Main Computer Room. The UPS is an Eaton

“93E‐60/40”, 32KW/40KVA UPS with 208VAC output. The UPS appears fairly new and is in good condition. However, the single group of batteries serve both panels “UPS‐P1” and “UPS‐P2”, which doesn’t meet A/B side redundancy requirement from VA OIT standard.

The MCR A114 serves data outlets at west portion of the first floor.

7.2.3 Telecom Room B122:

The Telecom Room accommodates two 2‐post data racks with network equipment and patch panels serving data outlets at east portion of the first floor.

Fiber splice boxes are mounted on a 2 x 4‐foot plywood backboard on the wall and receive fiber optic backbone cables from MCR A114.

Horizontal cables are routed through ladder trays above the racks to space above the ceiling through conduit sleeves on the back wall. The existing cable installation is lacking in cable management.

7.2.4 Telecom Room A312:

There is no existing Telecom Room on the second floor and on the fourth floor serving telecom outlets on those floors.

The Telecom Room A312 on the third floor accommodates nine 2‐post data racks with network equipment and patch panels serving data outlets on the second floor, third floor, and fourth floor.

Fiber splice boxes are mounted on a 2 x 4‐foot plywood backboard on the wall and receive fiber optic backbone cables from MCR A114.

Some horizontal cables are routed through ladder trays above the racks to space above the ceiling through conduit sleeves on the back wall. Other cables are routed through poke‐through conduit sleeves on floor. The existing cable installation is lacking in cable management.

7.2.5 Telecom Room A502:

The Telecom Room A502 on the fifth floor accommodates two 2‐post data racks with network equipment and patch panels serving data outlets on the fifth floor.

Fiber splice boxes are mounted on a 2 x 4‐foot plywood backboard on the wall and receive fiber optic backbone cables from MCR A114.

EHRM Infrastructure Upgrades Design Narrative

Horizontal cables are routed through ladder trays above the racks to space above the ceiling through conduit sleeves on the back wall. The existing cable installation is lacking in cable management.

7.3 Proposed Electrical Work for the Project

7.3.1 New Cables:

7.3.1.1 Backbone Cables: New 24‐strand OM4 multi‐mode fiber optic cables within one 2‐inch inner‐duct in two 4‐inch conduits ((1) 4‐inch conduit as spare) will be provided from MCR A114 to each Telecom Room.

7.3.1.2 Horizontal Cables:

The existing horizontal cables are CAT 5 or CAT 5E cables, which utilize technology over 20 years old and have limited bandwidth (100MHz). They will be replaced by new CAT 6A cables for the project. The existing cables are currently routed in above‐ceiling slab suspend mounted 6”x6” metallic wireway along with telephone and MATV system conductors.

CAT 6A cable is augmented version of original CAT 6 cable. CAT 6A cables make use of their higher standards by allowing full 10GBASE‐T transmission speeds of up to 10 Gbps, at 500MHz of signal bandwidth, over 100 meters (330 feet). The 100 meters (330 feet) consists of 10 meters (35 feet) for patch cables and 90 meters (295 feet) for total fixed cabling.

All horizontal UTP CAT 6A cables shall be terminated to T568B per OIT

Design Guide Templates.

7.3.1.3 Cable Route:

Cable trays will be provided in the MCR and in the TRs to route cables in the TRs. Provide dividers in the trays so fiber optic cables and CAT 6A cables will be routed separately in the same trays.

Unless otherwise noted, all the cables out of the MCR and the TRs will be routed in the existing 6”x6” wireways, or installed on new J‐hooks above the suspended ceiling in corridors, if the existing wireway is more than

50% filled with existing and new cables. J‐hooks will be provided no more than 5 feet apart and will be supported from building structure. Cable route will be coordinated with existing equipment, pipes and ductwork above the ceiling. Conduit sleeves will be provided for cable penetrations through walls, floors, and ceilings. Fire stopping will be provided for conduit penetrations through fire rated walls, floors, and ceilings. Where fire rated penetrations are required, UL listed assemblies shall be used.

7.3.2 Diamond Analysis:

So as to ensure new telecom system performance with CAT 6A cabling to meet Cerner

Infrastructure requirements, Design Guide document ‘SOCAMES 6 Design Alert 1’ by

VA OIT provides a three‐dimensional estimation approach called ‘Diamond Analysis.’

It was provided to assure that the fixed cables being installed don’t exceed the

EHRM Infrastructure Upgrades Design Narrative specified UTP cable segment of 90 meters (295 feet) from existing or new Telecom

Rooms. Diagonal radius of 80 meters (262 feet) is used to draw a diamond shape using the TR as the center of the diamond. The 80‐meter (262‐foot) coverage instead of 90‐ meter (295‐foot) is used “in order to account for vertical cable distance, installation of slack for bypassing obstructions, cable management, bend radii and other in‐situ obstacles” per the ‘SOCAMES 6 Design Alert 1.’

The existing Main Computer Room and existing Telecom Rooms will be utilized for the project, plus a new TR room B201 for the second floor and a new TR room B444A for the fourth floor respectively. See Sheet GI‐101 for UTP horizontal cable distance assessment (Diamond Analysis) for all the TRs for the building, per ‘SOCAMES 6 Design

Alert 1.’

7.3.3 New Telecom Outlets:

7.3.3.1 Wall Outlets:

The majority of existing wall mounted telecom outlets use 4‐port outlets with a single‐gang back‐box and faceplate per outlet. A few telecom outlets use 1‐port or 6‐port outlets with a single‐gang back‐box and faceplate per outlet. While replacing all existing CAT 5 and CAT 5E cables by new CAT 6A cables existing back‐boxes for the telecom outlets may remain for reuse. All existing telecom jacks will be replaced by new CAT 6A

RJ45 jacks with new faceplates for the outlets. The new 4‐port telecom outlets will consist of three jacks with Gray, White, and Blue colors respectively and the fourth as blank with cover. Stainless steel faceplate will be used as cover for the new telecom outlets. Three color coded CAT

6A cables with Gray, White, and Blue colors will be provided for color coded jacks for each of the outlets accordingly.

7.3.3.2 Wireless Access Point (WAP):

Ceiling surface mounted WAPs are located throughout the buildings. All the existing cables for the WAPs will be replaced by new CAT 6A cables.

Above ceiling or wall mounted 2‐port data outlet will be used for each ceiling or wall mounted WAP.

7.3.4 Labeling:

Labels will be provided for each wall outlet and outlet for WAP, with an identification number for each outlet. The identification number will include the information of

“from which Telecom Room (TR#), from which Data Rack (DR#), from which Patch

Panel (PP#), and from which Port of the Patch Panel (PO#)” the cable is fed, “to which

Room (RM#), to which Telecom Outlet (TO#), and to which Jack of the Outlet (J#).” The proposed numerical format for the outlet ID is as below –

TR# ‐ DR# ‐ PP# ‐ PO# ‐ RM# ‐ TO# ‐ J#

All the new cabling will also be tagged on both ends of the cable and in any pullbox required, with the same label(s) as data jack(s) fed by the cable(s).

All labeling shall be ANSI/TIA/EIA/606C compliant. They shall be machine printed with black lettering on white field.

EHRM Infrastructure Upgrades Design Narrative

With labeling for the new telecom outlets, Contractor shall update a template for new cabling inventory for the project. The template in Excel will be provided from VA

Project Manager per Contractor's request. The new cabling inventory spreadsheet will be saved in an electronic file with a hard copy attached to data cabinets/racks for future management, updating, and trouble shooting.

7.3.5 Main Computer Room A112:

7.3.5.1 New Data Cabinets: Four new OIT standard Data Cabinets will be flush mounted on raised floor with floor stands on concrete floor slab below raised floor. The Data Cabinets will be anchored and support from the floor stands. See structural design for Data Cabinet installation requirement. The new Data Cabinets will accommodate the following:

Existing service equipment from AT&T and Time Warner

New fiber optic patch panels to receive existing fiber optic cables from

MPOE on P2 level

New equipment provided by VA OIT (i.e. core switches, network switches, voice gateways, and wireless LAN controllers, etc.)

New 48‐port patch panels for CAT 6A cables

New data cabinets installed Power Distribution Units (PDUs)

New horizontal and vertical cable management system

New data cabinet mounted environment sensors

New water leakage detection loop connection

3‐foot clearance around the new data cabinets shall be maintained per OIT standard.

7.3.5.2 New UPS System

The existing UPS system (E)”UPS” in the MCR consists of a single group of batteries, a UPS, a step‐down transformer and two section panels “UPS‐

P1” and UPS‐P2”. It doesn’t provide any redundancy so not meet VA OIT requirement for UPS.

Two new UPS systems (N)”UPS‐A” and (N)”UPS‐B” will be provided to replace the existing (E)”UPS”. New Galaxy VS 40KW UPS system from APC

(Schneider Electric) is used as design basis. Each of two new double‐ convertion UPS systems will consist of four sections – a UPS cabinet with rectifier, inverter; a Lithium (Li‐Ion) battery cabinet with strings of chargeable batteries and battery breaker; a maintenance bypass cabinet with unit input breaker to receive 480V, 3‐phase power, maintenance bypass breaker, unit output breaker and output transformer to step down

480V to 208Y/120V; and a Power Distribution Unit with two 42‐pole electrical panels (N)"UPS‐PA" and (N)"UPS‐PB".

Each new UPS system will be rated as 40KW/40KVA with 480V, 3‐phase input and a 208Y/120V, 3‐phase, 4‐wire output. An existing 150A/3P circuit breaker at existing switchboard “1ESS” in Emergency Switchgear

EHRM Infrastructure Upgrades Design Narrative

Room P201 on P2 level feeds the existing (E)”UPS”. Switchboard "1ESS" feeds mechanical loads and others. It is considered as Equipment Branch of the Essential Electrical System. Per part 8.5.3 of VA Telecommunications and Special Telecommunications System Design Manual (FEB. 2016)", "Electrical power (for Main Computer Room) shall be on critical branch of the Essential Electrical System." Existing switchboard "2ESS" is considered as Critical Branch of the ESS. The new (N)”UPS‐A” and (N)”UPS‐B” will be fed from the switchboard "2ESS" with two new 80A/3P feeder breakers in space of the existing switchboard. 30‐day meter reading of the existing switchboard has been provided for the project in order to determine its peak demand for reusage to accommodate new loads, per NEC 220.87.

The new (N)”UPS‐A” will be installed and connected prior to disconnect and remove the existing (E)”UPS”, to minimize downtime of UPS backup.

Each of the two new UPS systems will provide 40 minutes runtime to backup essential load in the MCR. Battery Monitoring System (BMS) is provided with the new systems. Disconnect switches with external connections will be provided for the BMS and low voltage cable connections will be provided for the new UPS systems per coordination with the UPS supplier. Grounding Electrode Conductors (GEC) will be provided for the new step‐down transformers for the UPS systems.

7.3.5.3 Provide new below‐raised‐ floor concrete floor mounted twisted‐lock receptacles, NEMA L21‐20R, under data cabinets to serve data cabinet mounted PDUs, per “VA CFM/OIT Design Guide Templates for Critical

Telecommunications Spaces in Clinical and Non‐Clinical Environments.”

Provide a 208/120V, 3‐phase, 4‐wire circuit from the new UPS panels

(N)”UPS‐PA” and (N)”UPS‐PB” at MCR dedicated for each twisted‐lock receptacle.

7.3.5.4 Provide mesh type cable trays above data cabinets for cable runs to and from the data cabinets. The mesh cable trays will be supported from concrete slab above drop ceilings. Seismic bracing will be provided for long thread rod supports above the ceiling.

Provide wall mounted conduit sleeves to route cables from cable trays to space above ceiling.

7.3.5.5 The MCR A114 will serve telecom outlets at west portion of the first floor of the building with new CAT 6A cables.

7.3.6 Telecom Rooms:

7.3.6.1 Existing Telecom Rooms B122 on the first floor, A312 on the third floor, and A502 on the fifth floor will be reused to serve telecom outlets on the related floors.

7.3.6.2 The existing Pharmacist Room B201 will be reassigned as a new Telecom

Room to serve all telecom outlets on the second floor.

EHRM Infrastructure Upgrades Design Narrative

7.3.6.3 A portion of the existing Group Therapy Room B444 will be reassigned as a new Telecom Room B444A to serve all telecom outlets on the fourth floor.

7.3.6.4 New 4‐post data racks with base plates anchored to concrete floors will be provided for each of the TR’s. Per VA OIT standard, 7 feet tall, 23.75 inches wide and 30 inches deep cable management racks with 45 Rack Mount

Unit (RMU) space, Legrand Mighty Mo 20 or equivalent, will be provided as the new data racks. However, per coordination with Legrand tech support, Mighty Mo 20 racks are not seismic rated. New data racks provided shall be seismic rated per confirmation from VA. To provide sufficient rack mount unit spaces, the number of new data racks to be provided for each of the TR’s is as below:

TR B122 – (2) data racks TR B201 – (3) data racks

TR A312 – (3) data racks

TR B444 – (2) data racks

TR A502 – (2) data racks Rack mounted equipment will include fiber optic patch panel to receive

OM4 backbone cables from MCR A114, network equipment provided by

OIT and 48‐port patch panels for horizontal cables. A horizontal cable manager will be provided below each patch panel. Vertical cable managers along front sides of the racks will be provided.

Two CyberPower OL3000RTXL2UHVN UPS's will be mounted on the racks.

Each CyberPower UPS is rated as 208VAC, 1‐phase, 2.7KW/3KVA. Two

208V, 1‐phase, 20A Vertical Power Distribution Units (PDUs) will be provided for the racks. Two new, above data racks, ceiling mounted twisted‐lock receptacles with NEMA L6‐20R configuration, will be provided to serve the rack mounted UPS's, which will feed rack mounted

PDU's.

As design intent, we try to maintain 3 feet clearance in front of and at both sides of the new data racks in the TRs; however, some TRs have limited space. Maintaining existing racks/equipment operational while providing new racks/equipment in the same rooms will add some challenges. The

OIT standard rack, Legrand Mighty Mo 20 or equivalent, is a 4‐post rack, which will occupy more floor space than a regular 2‐post rack. Close coordination with the VA facility and with VA OIT has been performed to ensure the number of new data racks can fit in the room and also meet project and OIT standard requirements. Chatsworth Product (CPI) 19" wide, 4‐post, adjustable server rack is proposed for the project. It is

Seismic rated with 45 Rack Mount Space (RMU) and will take less space than the Mighty Mo 20 rack. Mighty Mo 20 rack is not seismic rated.

7.3.6.5 Power for the Telecom Rooms:

EHRM Infrastructure Upgrades Design Narrative

Two 208/120V, 1‐phase, 3‐wire with grounding circuits will be provided for the two twisted‐lock receptacles at each TR. The circuits will be from nearby 208/120V branch panels from existing Critical Branch essential electrical system. The new telecom loads from each TR will be supplied by circuits from a panel on the same floor.

New 120VAC, 20A receptacles with red faceplates will be provided at TRs.

The receptacles will be fed by Critical Branch essential electrical system.

New Telecom Room Fan Coil Unit (TFC) will be provided for each TR. A

208VAC, 20A circuit from nearby branch panel from existing Equipment

Branch essential electrical system will be provided for each new TFC, per

VA design standard. Because the existing Equipment Branch 208/120V panels are located on P2 and roof levels only, the new circuits for TFCs will be fed from these panels. The new TFCs for TRs on the first and second floors will be served by the panel on P2 level and TFCs for TRs on the third, fourth, and fifth floors will be supplied by the panel on the roof level. All the junction boxes and local disconnects serving the new TFCs at the new

TRs shall be permanently labeled for which panel and circuit and which floor the circuit is from.

Where the existing branch panels are used for new loads, 30‐day meter reading of them is required to determine peak demand of the panels, per

NEC 220.87. It is permissible to use 14‐day meter reading to determine existing peak demand, per government’s response to RFI 01. If the panel will be overloaded with the new loads or the panel is out of circuit for the new loads, a new panel will be provided to accommodate project needs.

Load calculation for its upstream step‐down transformer and the related

480/277V panel has been provided to ensure the existing transformer and the upstream panel are not overloaded with new loads for the project.

7.3.7 Grounding and Bonding for Telecom:

No grounding or bonding is currently dedicated for the telecom system for the building; a new grounding and bonding system will be provided. It will consist of the following per VA Telecom Design Manual and TIA/EIA standards:

A Telecom Main Grounding Busbar (TMGB) at MPOE P201 on P2 level

A Telecom Grounding Busbar (TGB) at MCR and at MCR and at each TR

Bonding conductor connection will be provided between TMGB at MPOE and existing Main Grounding Busbar at Main Service Switchgear “MSSA” at Main

Electrical Room P205 on P2 level. Intersystem bonding terminations will be provided for connecting the intersystem bonding conductors between the two systems.

Bonding connections will also be provided for the existing raised floor on the

MCR.

7.3.8 Construction Phasing for Electrical:

7.3.8.1 Construction sequence should be considered and coordinated to minimize impact on existing facility operation during the construction. Contractor shall coordinate with VA facility, project manager and VA OIT and provide new telecom system including data cabinets, data jacks, equipment, cables, pathway, and all required connections prior to disconnecting and removing existing telecom systems, in order to minimize service downtime for the areas to be worked.

7.3.8.2 For existing telecom room with limited space, Contractor shall carefully unbolt and slightly move/rotate existing data racks to save space for new data jacks. Existing equipment and cabling shall be supported and protected while installing the new equipment.

7.3.8.3 The existing third floor TR Room A312 supplies cables for data outlets on the second, third, and fourth floors. For those three floors, proposed work sequence is as below:

1) New TR and equipment on the second floor and fourth floor with associated cabling should be installed prior to work on the third floor.

2) Disconnecting and removing existing data racks, equipment, and cabling in Room A312 serving the second and fourth floors.

3) Install new data racks serving the third floor at the existing rack locations for the second and fourth floors. Unbolt and slightly move/rotate existing racks for the third floor if required for the new rack installation.

4) Disconnecting and removing existing remaining data racks, equipment, and cabling in Room A312 after new racks, equipment, and cabling installed for the third floor.

7.3.8.4 For the telecom work, which requires equipment disconnection and/or reconnection, and for any electrical panels or transformers to be replaced for the project, the work should be scheduled at night or in weekends so the electrical replacement work will have minimum impact on the facility daily operation.
