- Description
- This modification is being posted for clarification purposes only. Environmental Control Unit- The Atmospheric Early Warning system (AEWS) at the Ogden Air Logistics Center (OO-ALC/LHE) is seeking acquisition of Environmental Control Units (ECU). The Government is currently refining an acquisition strategy for ECU?s to support remote radar facilities in Alaska, Hawaii, Canada and Puerto Rico. The new family of ECUs have updated performance requirements outlined for the AN/FPS-117 Radar. This AN/FPS specification is used only as a reference for this Sources Sought Synopses (SSS). The plan is to purchase in fiscal year 2004 approximately 52 identical ECU?s. This SSS is for market research purposes only and respondents are reminded a formal solicitation may not necessarily result. Information received as a result of this market survey may be reflected in a formal solicitation. The Government will not pay for any information received in response to this request, nor will the Government compensate respondents for any costs incurred in developing information provided to OO-ALC-LHE. Recommend that information be limited to that readily available and that proprietary information not be included. However without written permission from the respondent, OO-ALC-LHE will not release to any firm, agency or individual outside the Government any information marked proprietary Response packages should be delivered in two paper copies, including brochures, software copies (Microsoft Word or Excel) may be delivered along with the paper copies. The response packages are due to Justen Bonham OO-ALC-LHKC address: 6029 Wardleigh Road, Hill AFB UT 84056-5638. General Requirements: The new ECU?s will replace existing equipment at remote radar sites. Modifications to existing sheet metal ducting may be required. Repair of wall from any hole created from removal of existing duct shall also be required. Removal of ducting may include potential Hazmat problems such as asbestos in the wall/piping and lead paint. Intake dampers will need to be routed and controlled remotely to both inside and outside of the building/tower as weather dictates. Return air must be modulated to avoid a negative pressure inside the building/tower. Two ECUs will be installed and work in tandem alternating as back-up and have a direct digital control (DDC) panel with remote diagnostic and programming capabilities at each radar site. Since commercial off-the-shelf equipment is expected to satisfy this requirement, a twelve-month warranty of equipment and installation and support software is required beginning after successful acceptance tests at each site. Contractor will be required to perform site surveys since many sites are unique. Operational manual, drawings and Interface description (ICD) shall be included. Refrigerant used must comply with the environmental laws of the country the ECU is operating in. Scope: The microprocessor control system (MCS) shall be fully integrated and installed as a complete package by a single contractor. The contractor shall furnish all materials including all computer hardware and software, operator input/output peripherals, field hardware panels, sensors and field control devices and installed wiring. The contractor shall be responsible for engineering, installation, labor services, system calibration, initial software programming and system checkout as necessary to provide a complete and fully operational MCS as specified herein. Control power: 120/208 volts, 3 Phase, 4 wire, 60 Hertz. Cannon type connectors shall be used. Control power and signal wiring shall be segregated throughout the installation of this project, and shall be kept at least three feet apart at all times. Under no circumstances shall power and signal wiring be run in the same raceway. Control signal wiring shall be routed clear of all lighting ballasts and other electro-magnetic devices that may damage the integrity of the control signal. Controller should be shielded from possible outside interference. Specific requirements: Equipment must be capable to withstand cold soak temperatures of minus 70 F and must be able to maintain 60 degrees Fahrenheit within four hours. Operating temperatures will be from 0F to 120F. Return air dry- bulb temperature shall be 60 F plus or minus 5F at 100F ambient with a total cooling capacity of 60,000 BTUs. Total heating capability shall be at least 15KW. Due to restricted facility space the ECU must have exhaust, intake and return ports originating from the top and or front of the ECU. All components must be readily accessible from the front of the ECU. ECU must be able to withstand storage altitudes up to 40,000 feet. Operational altitudes are between sea level and 15,000 feet. The DDC system shall be capable of executing the following standard control routines: ECU heating and ECU cooling failure alarms, high and low temperature alarms, maintenance time reminders, trend logs, supply air reset, enthalpy control, remote damper control, economizer or free cooling control, automatic and manual switchover of backup ECUs, fault override capability and remote reset for heat, cooling and fan modes. Sensors will be installed to monitor fault isolation and provide remote diagnostic feedback for the following: high temperature switch, low temperature switch, return air, outside air, supply air, mixed air, damper control, condenser air inlet, evaporator air pressure, differential air pressure for filter, expansion valve, condenser fan, ECU cabinet temperature, room thermostat, humidity control, dry bulb, wet bulb, high head pressure alarm and low suction pressure alarm. Computer interface: A standard interface protocol shall be used. Transfer Control Protocol Internet Protocol (TCP/IP) is preferred for the AN/FPS-117 system. The controller output shall be Category 5 and connect to existing 10 Base T- 10 Base 2 hub /converter in the equipment room. Vendor will need to integrate controller interface protocol with existing proprietary AN/FPS 117 radar software. Expansion: Expansion of the Microprocessor control systems (MCS) shall accommodate additional hardware components to meet future expansion requirements but shall not require special software to achieve this expansion that modifies the operation of the system or its operating systems.
