Executive Summary

This project involves the design for interior renovation of an existing Dialysis space to improve the condition of the unit, which is currently undersized, outdated and has functional deficiencies. This project will require use of existing 5W space to be converted into temporary Dialysis clinic while the main space is being renovated.

The primary goal of this project is to fully renovate the existing Dialysis Suite to modernize and right size it to current VA and industry standards. The space shall be designed in a manner that creates efficiency, provides a functional lean flow and allows the maximum amount of dialysis patient care station. The space should also be flexible to serve as an infusion clinic two days/nights a week. The space should be an open plan to allow direct nurse supervision of patients, maximize circulation, include right sized spaces and locate support spaces so they are conveniently accessible.

April 24, 2025 protect penetrations and joints within fire-resistance-rated walls and horizontal assemblies. The building codes require these breaches to be protected, and the UL Solutions Qualified Firestop

c. Training

1) Training will be specified for any system which incorporates a new technology or system component that is not familiar to the maintenance and support staff presently trained on the existing systems.

3. Telecommunications Pathways and Spaces

a. Interior Spaces

1) Telecommunication Rooms (TR): The new TR will be constructed under the EHRM Project and will be located in Room 5W07 and will be stacked from floor to floor. The purpose of the TR rooms is to support horizontal and backbone building cabling, and voice and data equipment. The size of the TRs will be per ANSI/TIA 569-E and will meet/exceed the minimal size TR (Minimum size 10’ x 10’).

a) All walls will receive 3/4” fire treated plywood installed 6”to

8’-6” AFF. The rating stamp will be exposed.

b) The room will have dedicated power, cooling, and standard lighting. Cooling will be 24/7/365, maintaining 68°F to 72°F. The

TR will be humidified to maintain a humidity level between 30% and 60%. Dedicated 120 volt and/or 208 volt power receptacles will also be required.

c) Doors will be equipped with rough-ins for proximity readers, door status switches, exit devices, and camera locations for entry access.

d) New 19” (W) x 7’ (H) equipment racks with vertical and horizontal wire management will be installed as required.

e) Grounding of all equipment to a ground bar located in the room will be required.

f) UPS power will be provided for Owner-provided network switches.

b. Interior Pathways

1) General: Anywhere that a penetration is required through a corridor, wall or hard ceiling for telecommunications cabling, installation of conduit sleeves will be required. For penetrations serving more than 12 cables, mechanical firestopping will be required.

2) A wire basket cable tray system will be installed in all corridors within the areas identified under this scope of work to support voice, data, April 24, 2025 video surveillance, and CATV. Security system and access control system cables will be routed within their own conduit pathway.

a) Nurse Call, fire alarm, overhead paging, and other low voltage systems will use separate dedicated cable supports and/or conduit. Nurse call cabling for code blue applications will be routed in their own separate conduit system. Cable supports will not be supported from the cable tray system. Access control and PACs system cable can be installed in a cable tray segregated from the other systems’ cabling in the tray.

4. Structured Cabling System

a. The telecommunications infrastructure will be a “structured cabling system” designed and installed to ANSI/TIA requirements and the Infrastructure Standard for Telecommunications Spaces (ISTS), Version 4.0, issued by U.S. Department of Veteran Affairs - Office of Information and Technology.

b. A manufacturer’s System Assurance Warranty of at least 20 years will be required for the system.

c. All horizontal cabling (i.e., cabling between the workstations and technology rooms) will be Category 6A, 4-pair unshielded twisted pair cable for all applications. Cabling shall be identical for all applications (i.e., voice and data). All

Category 6A cabling will terminate onto a Modular Patch Panels on equipment racks in the TR’s. All horizontal cabling installed in plenum spaces shall be plenum rated.

d. Horizontal cabling from each Wireless Access Point (WAP) location will consist of two Category 6A, 4-pair unshielded twisted pair cables installed from the nearest TR to an outlet box at each WAP location. Terminate both ends of the cable onto a CAT 6A RJ-45 outlet, green in color onto both ends of the cable at each outlet box enclosure. Snap each outlet onto a 2-Port faceplate, white in color.

e. Each information outlet location will receive two (2) Category 6A jacks (RJ45).

The outlet box will be a typical dual gang backbox with a single gang plaster ring mounted at 18” unless otherwise noted. Special use outlets will be configured per the requirements of the equipment serviced by the outlet (copy machines, printers, wall phones, etc.). Two outlets will be provided for every 50 NSF of programmed space per room. High density WAOs, if required, will have four

RJ45 jacks).

April 24, 2025

f. The system will be required to be fully tested to CAT 6A performance requirements and will be tested at 500 MHz.

g. Labeling and Administration

1) Labeling and administration will be provided for the TIP to include each cable end, patch panel ports, racks, and patch panels. Work area outlets will also be labeled with source TR and patch panel port identifier. All system components will follow the numbering scheme currently used for the facilities on this campus.

h. Warranties

1) Labeling and administration will be provided for the TIP to include each cable end, patch panel ports, racks, and patch panels. Work area outlets will also be labeled with source TR and patch panel port identifier. All system components will follow the numbering scheme currently used for the facilities on this campus

G. Security Systems

1. Wireless Access System

a. Wireless Local Area Network (WLAN): A WLAN will be provided for the VA enterprise network and for a separate guest WLAN. A third-party vendor that has a national account with the VA, will provide heat maps to verify WLAN coverage and will design, provide, install, terminate, test, and turn up the WAPs in accordance with VA Standards.

2. Access Control System

a. Access control system is existing to remain in service. The system is a Lenel, On-Guard, PC-based access control system. New card readers (smart card), door contacts, electrified hardware, request to exit devices, and control panels will be installed per project requirements.

3. Video Surveillance System

a. New cameras will be provided and connected to the existing video surveillance system. New cameras will be IP based, with Category 6A cable drops to each camera. New network video recorders (NVR) will be specified as required.

1) Any required storage upgrades are not a part of this contract.
