- Statement of Work Description: This is a Small Business Sources Sought notice. This is NOT a solicitation for proposals, proposal abstracts, or quotations. The purpose of this notice is to obtain information regarding: (1) the availability and capability of qualified small business sources; (2) whether they are small businesses; HUBZone small businesses; service-disabled, veteran-owned small businesses; 8(a) small businesses; veteran-owned small businesses; woman-owned small businesses; or small disadvantaged businesses; and (3) their size classification relative to the North American Industry Classification System (NAICS) code for the proposed acquisition. Your responses to the information requested will assist the Government in determining the appropriate acquisition method, including whether a set-aside is possible. An organization that is not considered a small business under the applicable NAICS code should not submit a response to this notice. This notice is issued to help determine the availability of qualified companies technically capable of meeting the Government requirement and to determine the method of acquisition. It is not to be construed as a commitment by the Government to issue a solicitation or ultimately award a contract. Responses will not be considered as proposals or quotes. No award will be made as a result of this notice. The Government will NOT be responsible for any costs incurred by the respondents to this notice. This notice is strictly for research and information purposes only. Background: The National Institutes of Health (NIH) is the nation's leading medical research agency and the primary Federal agency whose mission is to seek fundamental knowledge about the nature and behavior of living systems and the application of that knowledge to enhance health, lengthen life, and reduce illness and disability, conducting, supporting and making medical discoveries that improve people's health and save lives. The National Institute of Neurological Disorders and Stroke (NINDS) Surgical Neurology Branch (SNB) is a part of the National Institutes of Health (NIH), conducting research into the causes, treatment, and prevention of neurological disorders and stroke. The NINDS mission is to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. Water-borne contaminants in animal drinking water can pose risks to research integrity, and could potentially harm rodent health and welfare. Therefore, the Building 35 Shared Animal Facility (SAF) has a requirement for animal drinking water that is essentially free from contaminants. The animal drinking water system in Building 35 is currently supplied by a building-wide, reverse osmosis (RO) system that is maintained by a service contract through ORF. Although a properly maintained building RO system will initially provide contaminant-free water, the building RO water is at risk of acquiring bacteria and other contaminants as the RO water recirculates throughout the building to supply labs and to supply the vivarium. To help mitigate the risk of acquiring water-borne contaminants from the building RO recirculating loop, the building RO supply water is further treated at the vivarium level using a dedicated recirculating loop, which utilizes both UV radiation and 0.2µ filtration for secondary treatment. Although this secondary treatment system initially provided adequate drinking water quality for the research animals housed in Building 35, over time this secondary treatment system has been compromised with bacteria and other contaminants. The source of the contamination is likely due to contamination within the Building RO supply loop, and the design weaknesses inherent in the secondary treatment system. The Chlorine Repressurization System (CRS) referred to in the Statement of Work, addresses the major design flaws in the existing secondary treatment system by eliminating the secondary recirculating loop and by providing a residual biocide (free chlorine) to protect against the formation of biofilms in the secondary storage tank and in the distribution header piping that directly supplies the bottle filling equipment. The CRS will also provide extra capacity (600 gallons) of chlorine-treated water to the vivarium. The additional treated water capacity is required in order to accommodate the tripling of rodent cages added during the recent expansion of the Building 35 SAF. The additional capacity will also assist in the provision of treated animal drinking water in the event of a sustained emergency or disaster event. Purpose and Objectives: The purpose of this acquisition is to replace the existing animal drinking water treatment system in the Building 35 Shared Animal Facility (SAF) that is consistently failing to provide the quality of animal drinking water that is required for the research animals on study. Scope of Work: Animals housed for research must be provided water that is essentially free of bacteria and other contaminants in order to minimize experimental variables, and to maintain acceptable animal health and welfare according to federal regulations. The Chlorine Repressurization System (CRS) proposed in this Statement of Work addresses the two major design flaws of the existing system: (1) The absence of a low-level residual biocide (free chlorine) to prevent the formation of biofilms on the wetted components of the system; (2) The elimination of the recirculating header loop which can continuously re-contaminate the reserve water supply. These design flaws have contributed significantly to the inferior quality of the animal drinking water and must be corrected. In addition to improving the animal drinking water quality, the CRS will also provide additional treated water capacity. The Building 35 SAF tripled in animal holding area after the completion of the Porter Neuroscience Research Center Phase 2 expansion project. No additional treated animal drinking water capacity was included in the initial building design. The 600 gallon storage tank designed into the CRS will accommodate the additional animal holding capacity and will also provide an adequate supply of treated animal drinking water to sustain the valuable research animals during emergency and disaster events. Contractor shall provide and install an Edstrom Industries (or equivalent) Chlorine Repressurization System (CRS) which utilizes chlorine as a residual biocide, does not recirculate water back to the master holding tank, and is specifically designed to provide drinking water for animals used in research. Specific Requirements a.System Requirements: The Animal Health Care Section has determined the following minimum requirements for a secondary animal drinking water treatment system that utilizes free chlorine as a residual biocide: i.Ultra-filtration of the incoming building RO supply water to 0.01µ utilizing a low maintenance, self-flushing membrane system. The ultra-filtration system will be equipped with a bypass line and valve to feed the vivarium bottle filling equipment directly, in the event that the chlorination system needs to be maintained or serviced. ii.50 (+/-) gallon, floor-standing polyethylene solution tank for premixing liquid household bleach with incoming RO supply water. The tank must be sealed with a removable lid to prevent the escape of chlorine fumes. The tank must also contain a solution level tree with alarming capability so that the system alarms in sufficient time for new solution to be added. iii.Wall-mounted chlorine injection system that will precisely meter the concentrated chlorine solution into the animal drinking water. The chlorine injection system must meet the following additional minimal requirements: 1.Concentrated chlorine solution injection must be controlled and monitored by the flow rate of the incoming RO supply water. 2.Chlorine injection system must have a mixing chamber to thoroughly mix the RO water and concentrated chlorine solution, after the solution has been injected into the RO water. 3.Chlorine injection system must have the ability to manually adjust the amount of concentrated chlorine solution that is injected into the RO supply water based on manual chlorine titration. The injection system must be capable of adjusting and holding to a concentration within a very tight range (1 ppm - 20 ppm). 4.Chlorine injection system must have a set of dry contacts for connection to a building automation system so that personnel can be notified of critical alarm conditions. iv.600 gallon, floor-standing polyethylene storage tank for storing the chlorinated RO animal drinking water, post treatment. The storage tank must meet the following additional requirements: 1.Contain a removable, bolt-down polyethylene cover which is initially sealed to atmosphere. 2.Equipped with level control tree for controlling on/off of the injection system and for controlling low level and high level alarm states. 3.Equipped with a safety overflow check valve. 4.Equipped with a 0.2µ air vent filter for filtering/venting atmospheric air while tank is emptying and filling. v.34 (+/-) gallon floor-standing, pressurized storage tank for staging the chlorinated animal drinking water prior to the on-demand delivery to the facility bottle filling equipment. The tank must contain an FDA approved liner and diaphragm (polypropylene, butyl). vi.Dual pump skid for water distribution. The dual pump skid must meet the following additional requirements: 1.Pumps must be centrifugal and manufactured using 316 stainless steel (passivated) 2.Pumps must be mounted on a 304 grade stainless steel floor-standing frame 3.Piping and fittings must be schedule 80 PVC 4.Two pumps are required for redundancy 5.Pumps must be three phase and sized (horsepower) for the intended water distribution capacity 6.Pumps must be controlled to cycle between each other so that water does not stagnate in either pump. 7.Controller must allow for one pump to operate during a failed pump replacement. Pump manifold system must be equipped with isolation/shutoff valves to allow for pump replacement while system continues to operate. vii.The CRS must connect to a header system that will deliver the treated water to the three bottle filling systems located in the cage wash area. This header system will be provided by others and will be non-recirculating. Once the treated water leaves the CRS, the water will either be used to fill water bottles, or will be flushed to drain. viii.All wetted components must be made of 316 grade stainless steel, or suitable plastic materials that will withstand exposure to aggressive RO water and concentrated free chlorine solutions without leaching harmful by-products into the animal drinking water that could potentially compromise research. The AHCS will require a materials list and will make the final determination on the suitability of the materials used in the design and manufacture of the system. ix.The manufacturer of the CRS must provide detailed submittal drawings for approval. x.The manufacturer of the CRS must have the following installation, system start-up, and system training capabilities: 1.Installers must be factory-trained by the manufacturer 2.Upon satisfactory installation and start-up of the CRS, the manufacturer will provide satisfactory on-site training to the owner.
