Description

PREPARED IN ACCORDANCE WITH THE FORMAT IN SUBPART 12.6, AS SUPPLEMENTED WITH ADDITIONAL INFORMATION INCLUDED IN THIS NOTICE. THIS ANNOUNCEMENT CONSTITUTES THE ONLY SOLICITATION; BIDS ARE BEING REQUESTED AND A WRITTEN SOLICITATION WILL NOT BE ISSUED. This solicitation is issued as Request for Proposal No. 2001-Q-04069. This procurement is being issued unrestricted under the NAICS code # 334516 with a size standard of 500 employees. This solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 97-27. The National Institute for Occupational Safety and Health (NIOSH), in Morgantown, WV has a requirement for one each of an Aerosol Test Chamber in accordance with the specifications contained herein. This chamber will allow for safe aerosolization and containment of biological and non-biological aerosols. Within this chamber, various pieces of sampling and control equipment can be tested under NIOSH projects. SPECIFICATIONS: One horizontal Aerosol test chamber capable of maintaining a uniform velocity profile and aerosol concentration profile across the cross-sectional area of the chamber throughout the test box, at an air flow range of 10 -- 1000 SCFM, with interior dimensions 30 inches square and approximately 19 feet long. Exterior flanges and attachments must not extend further than 6" from the surface of the chamber, the exception is the exhaust flange at the downstream end of the chamber. This exhaust flange shall allow the attachment of 12" diameter ventilation pipe and be no longer than 12" in length. An air mover is not included in this procurement as this chamber will be connected to a Phoenix controller which is connected directly to the building exhaust system. The chamber shall be composed of six modules bolted together and sealed at the connection flanges in the following order: nozzle box (for measuring flow rate), inlet HEPA box, 2 test boxes, and outlet HEPA box. The chamber should be mounted to a two-section steel 3' high cart with rollers. The chamber should contain the following components: Nozzle box (18 gauge stainless steel): This should be 30 inches square, 22 inches in length. The face plate shall contain four tapered nozzles to measure flow (4", 3", 2", 1" diameter openings). A pressure tap at the top of the box will be used to measure flow rate through one or more of the nozzles. A relative humidity and a temperature transducer shall also be mounted in the nozzle box. Electronic micromanometers (with analog or digital outputs) shall be included that are capable of measuring pressure within 1%. Humidity measurement shall be within plus or minus 3% RH in the range of 20% -- 80% RH. Galvanized steel inlet HEPA box: This should be 30 inches square and less than 32 inches in length and permit the installation of a pre-filter and a 24" x 24" x 11-1/2" HEPA filter. Access to the filters must be possible via side door(s). The filter box must be scan tested with an optical particle counter to give leakage of less than 0.01% at 0.3 micrometer test aerosol. The filter must be capable of removing greater than 99.97% of all 0.3 micrometer airborne particles from the air entering the box resulting in a clean air environment inside the chamber. #18 gauge stainless steel aerosol source box: This should be 30 inches square, 48 inches in length and permit the mixing of inlet air and aerosol. The 1" diameter aerosol inlet tube (18 gauge stainless steel) shall be mounted in the side of this box with its outlet facing upstream in the center of the box cross section. A flange for this tube shall be provided on both sides of the box. A plug shall be provided for the side not in use. The 90 degree bend in this tube shall not have a radius less than 2". This tube must be attached with a flange so that it is removable for cleaning and autoclaving. The outside end of the tube shall protrude at least 2" from the side of the box for attachment of tubing. Two stainless steel baffles shall be included to mix the air flow and two stainless steel (80 mesh stainless steel) screens shall be included to straighten the air flow. One baffle shall have a center opening with 10% of the cross sectional area of box. The second baffle shall have a uniform opening around the perimeter with an opening area of 20% of the cross sectional area of the box. The baffles and screens shall be mounted in such a way as to be movable for optimization of mixing and turbulence reduction downstream. Aerosol measurements downstream of the inlet box shall indicate a constant concentration within plus or minus 5% in the center 50% of the cross sectional area of the box. Turbulence intensity in the region downstream of the screens shall be less than 5%. Windows (16" x 16") made of acrylic plastic (3/8" thick) must be installed on both sides of the box upstream of the aerosol inlet to permit side access to the box for cleaning purposes. These windows must be provided with seals that do not leak under a pressure test. The window must be installed with quick release holders to allow easy access to the box. A fused silica window (5" x 16") shall be installed on the top to permit sterilization (the inactivation or killing of viable microorganisms) of the box using UV lamp. The window seals shall be tested by sealing the ends of the box and applying 2" w.g. pressure. The box shall hold this pressure for at least 30 minutes. #18 gauge stainless steel test section box (2 each): This box should be 30 inches square, 48 inches in length and contain the inlet side of the test piece. Windows (16" x 16") made of acrylic plastic 3/8" thick must be installed centered on both sides of the box to permit side access to the box for cleaning and experimental purposes. These windows must be provided with seals that do not leak under a pressure test. The window must be installed with quick release holders to allow easy access to the box. A fused silica window (5" x 16") shall be installed on top to permit sterilization (the inactivation or killing of viable microorganisms) of the box using UV lamp. The window seals shall be tested by sealing the ends of the box and applying 2" w.g. pressure. The box shall hold this pressure for at least 30 minutes. A series of 12 ports at least 2" apart shall be installed at the bottom of each side of the aerosol test boxes. These ports shall accept 1/4" NPT fittings for connections to equipment in the box. Plugs to seal these ports shall be provided. Galvanized steel outlet HEPA box. The design should be similar to the Inlet HEPA box. This should be 30 inches square and less than 32 inches in length and permit the installation of a pre-filter and 24" x 24" x 11-1/2" HEPA filter. Access to the filters must be possible via side door(s). The filter box must be scan tested with an optical particle counter to give leakage of less than 0.01%. The filter must be capable of removing more than 99.97% of all 0.3 micrometer airborne particles from the air entering the box resulting in a clean air environment inside the chamber. A hose adapter plate should be attached to the end of this pox to connect the chamber to the blower. The flange in the plate should allow attachment of a 12" ventilation duct. Additional requirements: All seams (chamber sections and widow framing) should be continuously welded to prevent any leakage of air. The flanges between all major sections (inlet HEPA box/aerosol inlet box/test inlet box/test outlet box/outlet HEPA box) shall be "quick connects". The entire system shall be leak tested by pressurizing to 2" w.g. The system should hold this pressure for 30 minutes. Four thermocouples with 10 channel display box and analog or digital output, one humidity and temperature transducer with display box and analog or digital output, three UV disinfectant lamps (Spectronics Corp #XX-15G or equivalent) and three GE #124 Quartz Glass (5" x 19" x 1/8") are to be included as well as 4 air flow nozzles and electronic micromanometers with analog or digital output. NIOSH will connect the 12" duct to a Phoenix Control capable of adjusting the air flow to a specific CFM (50 -- 1000 SCFM).
