Work includes general construction, alterations, and certain other items. Contractor shall provide services but not limited to furnish all supervision, labor, equipment, materials and transportation necessary to accomplish work for the demolition and replacement as required by specifications and drawings.

The purpose of this project is to address deficiencies associated with IT Closet Areas located within multiple buildings at the NMVAHCS. Multiple buildings on campus include Buildings 1, 2, 3, 4, 5/6, 8, 10, 11, 18, 39, 41, 43, 45, and 46. Construction includes renovating existing IT Closets and the construction of new IT Closets. Construction addresses deficiencies associated with IT Closet sizes, UPS deficiencies, grounding and bonding conditions within each closet, alarm monitoring, configuration of equipment within the closets such as cable trays/housings, rack configuration, sizing of sleeves for cabling, removing abandoned cable and addressing physical security needs. Provide new equipment rack(s) furnished with both horizontal and vertical cable managers, vertical bonding bars, UPS, patch panel and an optical fiber termination shelf. The termination of optical fiber is excluded from the scope of work. All existing cabling and fiber serving existing building data drops shall be retained and reused. IT closets shall be renovated with existing cabling to remain.

Comprehensive 3rd party inspections, testing and written reports for all Divisions are required and paid by the General Contractor. Contractor shall employ third party inspection consultants to perform all inspections required by this contract.

Contractor shall appoint a third-party individual, company or firm to act as the Commissioning Agent. The Commissioning Agent is the designated person, company, or entity that plans, schedules, and coordinates the commissioning team to implement the commissioning process.

Contractor is responsible for Asbestos Containing Materials (ACM) removal and mitigation where it occurs inside the IT Closet project area of work. Please also see the 2016 ACM survey (included in General Requirements 01 00 00, Appendix B) for suspected, selected locations. There will be no cost to the Government for any removal, testing, oversight or clearance of ACM. Traditional and Glovebag Abatement methods as stipulated in Specification Sections 02 82 11 and 02 82 13.13, are the only allowable methods of abatement. No alternate abatement methods will be considered.

Electrical Work: Includes all labor, material, equipment and supervision to perform the required electrical construction work on this project including materials and construction equipment to upgrade closet lighting with automatic control. Provide materials to install and wire up to four (4) additional 120 volt 20 amp duplex receptacles and up to two (2) new 120V 30 amp twist lock receptacles surface mounted to the two (2) post equipment racks. All the new circuits shall be wired to the emergency power sources indicated. Buildings 2 and 18 do not presently have emergency busses, emergency power will be provided with new 3-Phase UPS units with internal batteries and a dedicated branch panel for distribution. For communications functions, provide cable trays, two (2) post equipment racks with vertical wire management. Coordinate the rework of existing fiber optic lines serving existing closets to the new closet locations. Provide up to four (4) network drops in each new closet. Provide a new stationary wall mounted CCTV (Closed Circuit Television) camera in each closet. Provide access control for all the closet doors, coordinate with the door hardware schedule for additional requirements.

Provide a dedicated bonding system for the IT Closets. The bonding systems will include a secondary bonding bar in each closet and the bonding of equipment located in each closet to the new bonding bar. The existing fire alarm system will be modified by relocating and/or adding compatible smoke detectors to the existing building fire alarm system.

Contractor shall provide a 72-hour (Monday through Wednesday) load test on the following panels:

· Building 1 (EB1)

· Building 2 (2LA)

· Building 3 (EF3, EC2, 3N2A

· Building 5 (ENL5)

· Building 8 (8L2)

· Building 10 (10ERB)

· Building 11 (11BB)

· Building 18 (P18)

· Building 39 (R, E)

· Building 41 (DNL6, CNL6, CCL5, CTP7, 5CL5, BTP7, ACL5, ANL6)

· Building 45 (BLL45)

· Building 46 (EWL)

Contractor shall provide load monitoring data to the COR/AE. All panels, at the time of design survey (February 2019) had the required capacity to accept the added design load. This test is required by NEC 220.87 for verification that no loads have been added since the design level survey.

Mechanical, Plumbing and Fire Protection Work: Work includes all labor, material, equipment and supervision to perform the required Mechanical construction work on this project including provide material and construction equipment to equip deficient closets with a secondary, dedicated split system Computer Room Air Conditioner (CRAC). New CRAC Work includes: (1) installation of the indoor unit above the cable tray at the entrance of the closet; (2) installation of the associated condensing unit on the building roof or site; (3) installation of a new thermostat/humidistat in each IT closet; (4) installation of an integrated condensate pump, trap and drain line; and (5) installation/routing refrigerant, power and control lines between the indoor and outdoor units, providing refrigerant piping supports, roof penetration, curb and hood and wall penetrations. Refrigerant routing, structural supports, and penetrations shall be field verified and coordinated with the VA. Contractor shall submit shop drawings for approval showing the proposed routing, supports and penetrations prior to beginning any work. Provide space temperature sensor, space humidity sensor, auxiliary drain pan moisture sensor (not float switch) and supply air temperature sensors on all DX units and /or VAV terminals and connect these to the central Engineering Control Center (ECC) system for trending and alarm purposes via BACNet. All new split systems shall be addressable and controllable via the existing ECC. The central ECC system shall monitor space conditions and unit status and shall alarm the boiler plant operator or HVAC shop whenever temperature or humidity are out of tolerance, when water is in the HVAC secondary drain pan and when any supply air temperature does not match what is required by room conditions.

This project also requires reconfiguration of the existing building HVAC systems (duct, diffusers, grilles, bracing and supports) to maintain existing heating and cooling for the closet. This work on existing systems includes (1) relocating and replacing existing duct, (2) relocating and replacing existing diffusers to coordinate with the renovated IT closet space; (3) providing new structural supports for existing HVAC systems for locations where the ceiling is removed and/or other reconfigurations are required. Contractor is required to Test and Balance (TAB) new and existing HVAC systems per 23 05 93. This work requires preconstruction TAB readings to establish baseline performance for all existing HVAC systems serving the IT closet space.
