Description

The National Institute of Standards & Technology (NIST) has a requirement for a temperature-controlled Class 100 environmental chamber to house an Interserv optical pattern generator. The project shall be a turnkey installation, including design, fabrication, installation and certification. Because of the space constraints on installation and on the equipment to be installed, a site visit to verify all dimensions is required before beginning the project. The environmental chamber is to be installed in the chase adjacent to clean bay room 1(2130), Building 1, 325 Broadway, Boulder, Colorado. Care must be taken to protect the clean environment of the clean room = through barriers, clean construction techniques, etc. The chamber shall be a stand alone unit constructed of insulated, metal skinned clean room panels. The chamber shall include a rear access door, a front vertical slide window, interior fluorescent lighting and an HVAC unit with blower, water cooled condensing unit and SCR controlled reheat. The self contained chamber structure shall be face mounted into the = existing clean room wall. All modifications to the existing wall system, including moving the existing chase access door and some electrical services are the responsibility of the contractor. Specifications as follows: A) ENVIRONMENTAL CHAMBER INTERIOR CONDITIONS: (A.1) Horizontal air flow, 1600 cfm, 90 fpm max. (A.2) Temperature set point 20 degrees C. plus or minus 0.1 degrees C. (A.3) Pattern Generator equipment heat load 1 kW. (A.4) Lighting 60 fc, amber sleeved fluorescent. (A.5) Pressurization 0.05 to 0.10 in. WC. (A.6) Existing chase conditions (exterior to chamber) 20 degrees C plus or minus 2 degrees C, 40 percent RH plus or minus 5 percent. B) DEMOLITION: The existing pattern generator, existing environmental chamber and existing air handling unit will be removed prior to installation by the Government. Any other duct work, lighting, conduit, framing, etc., including the clean room wall area where the environmental chamber penetrates, is the responsibility of the contractor. All demolition is to be coordinated in advance with NIST staff. Existing clean room operations must not be compromised during installation of the chamber. Temporary barriers must be installed to isolate the clean room and minimize disruptions. C) ENVIRONMENTAL CHAMBER SHELL: (C.1) Dimensions: (Note: all dimensions to be confirmed by contractor at NIST and with Interserv) Chamber inside dimensions 127 in. wide, 60 in. deep and 96 in. high Maximum overall width of chamber including walls, and supply and return air plenums 144 in. (C.2) Wall and roof panels shall be foam insulated, durable metal skinned, clean room compatible construction. Panels shall have a factory applied white finish in baked enamel or epoxy. All trim shall be aluminum, satin anodized finish. Any framing used shall be gasketed or sealed for airtight integrity. Roof panels shall be rigid and capable of supporting 20 PSF in addition to lights, ducts, etc. (C.3) The front wall section of the chamber including the window area shall be easily demountable to allow installation of the pattern generator. D) DOORS: (D.1) Rear chamber door =96 30 in. wide, 80 in. tall, ADA approved door handle, door = closer, clean room compatible materials and finish, weatherstrip for positive seal. (D.2) Chase door relocation=96 There is an existing chase door = in the location where the new chamber is to be installed. As part of the demolition and reconstruction of the chase wall to accommodate the new chamber, this door and frame is to be removed, modified and reinstalled in a clean room panel near its current location. E) WINDOW: (E.1) Vertical slide window, 45 in. wide by 34 in. high. Aluminum satin anodized finish trim, 3/16 in. tempered safety glass, sealed airtight, upward vertical sliding unit (slides down toward floor to open) with counter spring supports and manual releases. The exact location of = this access window to be determined by Interserv. F) AIR HANDLER: (F.1) Air balance: 1600 cfm HEPA filtered air delivered to chamber, 25 cfm air loss to pressurization, 100 cfm lost to lamp exhaust, 1475 cfm return air to handler. (F.2) Commercial grade water-cooled interior mounted condenser, R-22 refrigerant, 208 volt 3 phase, condensate drain pan. (F.3) Blower isolated and balanced for minimum vibration and acoustic noise. (F.4) SCR controlled reheat unit providing zero-crossing infinitely continuous modulation from 0 to 100%. The heater unit shall be provided with safety interlocks including cabinet door interlock, automatic high limit control manual reset, air pressure and overcurrent. (F.5) Air handler shall be mounted in the area above the chamber. G) DUCTWORK: (G.1) Ductwork shall be adequately sized per = and constructed per SMACNA and ASHRAE standards. (G.2) All ductwork and = any plenum boxes or perforated panels shall be stainless steel, cleaned inside and out for clean room use. (G.3) Dampers shall be provided to adequately balance supply, makeup and return air flows. All dampers shall be stainless steel, cleaned inside and out for clean room use. (G.4) Any flex connections used shall be clean room compatible and cleaned inside and out for clean room use. H) AIR FLOW/AIR CHANGES: (H.1) Supply air shall be delivered through HEPA filters comprising the central 4ft. x 4ft. area of the right hand chamber wall or a = pressurized plenum with remote HEPA filtering and a perforated side wall. In either case, 1600 cfm shall flow into the chamber from the right and out through the left side wall/return air cavity. This left side wall = return air cavity should be adequately perforated and sized to provide uniform horizontal flow across the granite block, stages and optics of the pattern generator. I) CONTROLS: (I.1) A stand alone microprocessor control package shall be provided that provides a digital readout of chamber temperature and set point. (I.2) Controller shall have the ability to restart in a logical and safe manner after a power outage. (I.3) Chamber temperature shall be measured via a remote probe which = can be mounted anywhere within the chamber. J) ELECTRICAL: (J.1) All electrical work shall be performed per the National Electrical Code. (J.2) Chamber shall include a switched, 1 ft. x 4 ft. 2 tube = fluorescent fixture with amber tube covers, providing 60 fc at 36 in. Switch shall be mounted to be accessible from clean room side of chamber. (J.3) Chamber shall provide 2 110v duplex receptacles mounted interior. K) CERTIFICATION: (K.1) After installation, chamber shall be cleaned = inside and out using standard Class 100 cleaning practice. (K.2) Using calibrated equipment, measure temperature (logged over 24 hour period), pressurization, air flow and illumination level to demonstrate that specifications are met. (K.3) Particle counts =96 use laser particle counter to verify Class 100 conditions within chamber. (K.4) Demonstrate power fail recovery procedure. L) WARRANTY: (L.1) All components, materials and labor shall be covered by 1 year warranty. = M) DRAWINGS, MANUALS AND TRAINING: (M.1) A full set of as-built drawings shall be provided along with DXF format CAD files on disk. (M.2) Manuals for all components and equipment shall be provided and include certification data, PM procedures, troubleshooting instructions, and spare parts list. (M.3) Training shall be provided for up to 4 NIST personnel in proper operation and maintenance of the chamber and its controls. Delivery needed as soon as possible. This procurement is being conducted per FAR Part 13, Simplified Acquisition Procedures (below $100K). All specifications are addressed in this synopsis. Technical merit as well as price will be used to evaluate offers. As technical merit becomes more equal, price becomes a greater factor. When submitting a quote, please include business size, Federal Tax ID number, and Dun and Bradstreet number.
