NOTIFICATION OF INTENT TO SOLE SOURCE The New York District plans to solicit and award an Invitation for bid construction project for Building 738, Sherman Barracks, at the USMA West Point, NY. This notification serves three (3) purposes: A. To notify potential bidders of the Government’s intent to solicit a brand name(s) only component for this project. B. To identify potential sources that can provide an equivalent to the brand name only item(s). C. Notification of the Army’s intent to solicit brand name components as described below. 1. The items described below, under summary of requirements, are embedded in the construction project. The contract will be issued as a competitive Invitation for Bid solicitation. Only the components described below will be sole source, if no other sources are identified that can provide an equivalent system. In the event no equivalent sources are found, the brand name only justification will be issued pursuant to FAR Part 6.302-1, Only One Responsible Source. A subsequent market survey will not be published in support of a Justification and Approval for sole sourcing. Supplies of the brand name component will be provided directly to the Contractor(s) and not to the Government. 2. Summary of Requirements: (A) Complete Monaco Fire Alarm System (estimated cost = $320,000): Due to post wide compatibility issues and based on the capabilities described below of a Monaco Fire Alarm system, all new construction and renovation projects at the USMA, West Point are now featuring the latest version of the Monaco Fire Alarm Control Panel. The MAAP Plus Analog Addressable Integrated Radio Transceiver and Fire Alarm Control Panel is capable of point reporting up to 1584 addressable device points via proprietary UHF radio signal to the Monaco D-21 Enhanced Central Radio Control Alarm receiving system at West Point Fire Department Dispatch. New Fire Alarm installations include Mass Notification Systems (MNS) in accordance with DoD Unified Facilities Criteria (UFC) 4-021-01. The existing RF infrastructure provided by Monaco supports the UFC requirements for primary MNS communications. The Monaco Fire Alarm and integrated MNS system has the capability to remotely activate the in-building MNS messaging system and provide live-voice announcements directly from the D-21 Central Station at West Point Fire Dispatch. Each Fire Alarm System (FAS) and Mass Notification System (MNS) shall be a complete, supervised, non-coded, analog-addressable system, installed in class A configuration per NFPA 72. The FAS/MNS shall provide point reporting to the Fire Alarm Control Panel (FACP). The FACP shall in turn provide point reporting to the Monaco D-21 Central Receiving Station at USMA West Point Fire Department Dispatch. Point reporting, also known as point to point reporting, is the capability to relay the status of each addressable device and certain system components such as Signaling Line Circuits (SLC) to the D-21 Central Receiving Station in real time. The FAS/MNS shall be tested and perform as a critical life-safety system. The FAS/MNS shall be compatible with and shall communicate seamlessly with the D-21 Central Receiving Station, without impairing operational function or reliability of any existing FAS or MNS. Use of interfacing relays between the FACP and communications transceiver to provide point or zonal alarm trouble status shall not be permitted. All devices must comply with the Aug 1997 Federal Wireless communication commissions office of engineering and technology Bulletin 65, Evaluating Compliance with the FCC Guideline’s for Human Exposure to RF Electromagnetic Fields. (B) Best Hardware Lock Cylinders & Cores (Non-Electronic) (estimated cost = $68,000) Due to compatibility and consistency issues with keying at the USMA, Best lock is the USMA standard for lock hardware. This applies to locks that are not electronic and have status monitor capabilities compatible with the electronic security access system. Hardware locksets shall accommodate Best lock cylinders and cores. The Contractor shall provide cores to secure building during construction and shall turn over hardware cores to the government upon completion of construction. Government will replace Contractor cores with Best lock cylinders and cores after each area of the projects are completed is turned over to Government. (C) C Squared Systems, LLC Telecommunications system (estimated cost = $30,000) United States Military Academy, West Point Command and other authorized personnel always require access to distributed antenna systems specifically provided by C squared systems. Additionally, the need to comply with current Army regulations and standards further bolster the need to retain C Squared Systems to provide distributive antenna systems (DAS). C Squared Systems complies with Department of Defense (DoD), Network Enterprise Center (NEC), Information Systems Engineering Command (ISEC) standards for maximum readiness within the network systems at United States Military Academy, USMA. West Point will need these systems to meet the mission requirements outlined by Department of Defense (DoD) and Training and Doctrine Command (TRADOC). (D) Identiv uTrust Card Readers & Velocity Software (estimated cost = $200,000) Provide contact/contactless card readers that can read credential CAC cards whose characteristics of size and technology meet those defined by ANSI ISO/IEC 7816 in close proximity to the card reader and are in compliance with NIST FIPS 201-2. Provide readers with "flash" download capability to accommodate card format changes and the capability of reading the card data and transmitting the data, or a portion thereof, to the ESS control panel. These should be Identiv Model 8116 or 8216 and primarily used on locations requiring dual authentication, or the ability to be escalated to a dual factor scenario. (F) Electrical Power Meter: Shark Meter from Electro Industries/Gauge Tech (estimated cost = $4,000) The West Point's advanced metering system was developed based on the Army Directive 2014-10. The metering system consists of Shark 200 advanced meter to monitor electric utility. The existing system has gone through the cybersecurity and risk management framework to obtain an approved Authority to Operate (ATO). Any other meter beside Shark 200 will invalidate the ATO and will not comply with the Army Directive 2014-10. Additionally, this system has already been implemented and integrated into West Points advanced metering network (i.e water use treatment plant, USMA Academic building, etc.) (G) Ventrol Air Handling Units (estimated cost = $200,000) - Heating and cooling unit 4 pipe w/ separate CHW and HW coil sections - Heat wheel section - Heat pipe section/ bypass control damper - Galvanized steel heavy gauge integrated panel frame construction - Double wall construction/ panel thermal brake - Painted cabinetry - 4" Fiberglass Insulation - Internally mounted fan motor - Fully gasketed panel and frame members - Leakage less than .09 cfm per sq. ft. at 5.0" static pressure - Access doors with gasketed seals and stainless steel hinges - G-90 galvanized steel outer panels - Galvanized inner panels - WELDED, 5" Base rails - Direct Drive fans w/ permanent lubricated motors (no belts) - Filter section w/ 2" 30% and 4" 85% filters (1 set) - Chilled/HW water section, 5/8" tubes, threaded brass MPT - One drain and one vent per entire coil - FANWALL Supply/Return fan cube sections with Class III welded fans - Stainless Steel drain pan - Balanced fans to BV-5 no isolation needed - Premium eff motor - Panel Mounted ABB VFDs, one per fan/motor assembly - Main disconnect on main control panel - Motor control panel - 6 pulse VFDs w/ 5% line impedance - One complete spare fan/motor assembly per motor/fan type - Fan wall 2.0 Optimization by VENTROL in SAF/RAF, additional AF stations not required - Fan outlet guard on each fan cube - Backdraft damper on each fan cube, if more than one. - Startup. - All mechanical/electrical components and devices are all contained inside a filtered return air plenum space, which is an out of the elements mechanical equipment space large enough to house all the mechanical equipment, fan motors and control panels and their devices in one out of the elements work space.
