This acquisition is not reserved for Small Business, however, the bidder's size status may affect entitlement to award. The North American Industrial Classification System (NAICS) code is 335211 and the small business size standard is 750 employees. Item 0001- rental of dehumidification units, two (2) each; Item 0002 – rental of two (2) each cooling modules compatible with item 0001; Item 0003 -- rental of two (2) heating modules compatible with item 0001 above; Item 0004 – rental of four (4) each blower units for use with item 0003 above; Item 0005 – shipping charges for four (4) required shipments of above equipment. NOTE: See further specifications and table below for requirements and dates of above items 0001-0005. A OVERVIEW (TDD Equipment) To provide a super dry and temperature conditioned environment to the main ballast tanks and interior tanks of the submarine USS Albuquerque (SSN 706) to support sandblast and paint operations. 1. DESCRIPTION: For reliability, flexibility, and scheduling concerns, the TDD equipment will be split as two (2) duplicate, independent, and non-collocated systems positioned on opposite ends of the drydock. Each TDD system will consist of: (a) a desiccant dehumidification unit with an integral air-handler; (b) a temperature conditioning (cooling or heating) module positioned downstream of the desiccant dehumidification unit; and (c) a sixty (60) ton chilled water (chiller) unit, not provided by this Contract, dedicated solely to the temperature conditioning module when that module is a cooling coil. Initially, two cooling modules will be deployed, and, at the fall switch-over date, swapped for two heating modules. Eventually, the heating modules will remain and the desiccant dehumidification units returned. If the heating modules do not incorporate air-handlers of sufficient capacity, blower modules will be substituted for the desiccant dehumidification units. 2. EQUIPMENT: The equipment and their capacities/sizes are listed in Table A below and, except for blowers, subsequently described in the Specification. The equipment consists of two (2) similar desiccant dehumidification units and two (2) similar temperature conditioning modules. This Specification does not prevent the use of equipment that effectively combines the features of two or more machines such as a desiccant dehumidification unit with a downstream temperature conditioning module (e.g. thermostatically controlled chilled water coil downstream of a desiccant rotary structure within a desiccant dryer) or an air-handler integrated as part of a temperature conditioning module. The blower capacity can be met by two (2) units and a Y adapter if a single blower is insufficient. 3. LOCATION: The equipment will be used in Drydock #2 (DD#2) at Portsmouth Naval Shipyard (PNS). To include the framed base and any transitioning ductwork as reserved on the drydock floor plan, the desiccant dehumidification unit must be 16 x 8 feet or smaller and the heating or cooling modules must be 9 x 6 feet or smaller. The preference is that the cooling modules be of a design that does not integrate an air-handler for compactness since one is already incorporated in the desiccant dehumidification unit. However, the heating module may include an air-handler. 4.

DELIVERY: The equipment shall be fully charged and delivered to the site on the requested date in a ready-to-use condition. The Government can provide forklift services during normal work hours for removing the equipment from the vendor’s transport. If requested by the Vendor in advance and acceptable to the Government to provide training on the delivery date in-lieu-of a later start-up date, the Vendor shall instruct designated Shipyard personnel on how to properly run the equipment to include its operation, control, daily checks, & service contact(s). For multiple sets of comparable equipment with essentially similar operation, the orientation on a particular type of machine can be accomplished just once regardless of delivery dates. 2. PERSONNEL: To be allowed onto the Shipyard, personnel must be US citizens and carry appropriate personal identification. Vehicular access requires a non-expired personal Driver’s License and appropriate vehicle identification. Normal vendor access is available from 7 am to 3:30 pm Monday thru Friday from the Security Pass Office (Bldg 202 near Gate 1). To gain access to the drydock environs, personnel must possess and wear their own personal safety gear which must include: safety glasses w/ side protection, hard had, safety shoes with a ANSI approved reinforced toe box, and, at times, hearing protection. 3. PRICING: Proposals will be given to Contracting based on a twenty eight (28) day (short) month for a minimum of two (2) consecutive months for each machine with the option to extend monthly or weekly. Weekly extensions for each piece of equipment shall be billed at no greater than of the stated recurring monthly rental fee. Cost comparison amongst vendors is based on the expected usage for each piece and type of equipment plus the planned total number of scheduled shipping dates delineated in Section A. The proposal will provide credit for the equipment’s partial use during the last extension after the initial two month period and for any down time beyond forty-eight hours (two days). The cost of training, operation and control, and start-up fees shall be included in the monthly rate. 4. REPAIR: The Vendor shall provide to Contracting, the Engineering & Planning (E&P) Department Technical Liaison, and the Project Liaison as well as displaying on each major piece of equipment a point of contact and a telephone number for requesting repair. Within twenty-four (24) hours of initial notification of the need for repair, the Contractor shall have a knowledgeable and equipped technician on the job-site fully prepared to repair the rental equipment. The defective unit(s) shall be repaired within forty-eight (48) hours of initial notification or if the original defective unit(s) cannot be made operational, replaced within seventy-two (72) hours of initial notification. If the equipment failure does not arise out of abuse or negligence by the Government, the Contractor shall be responsible for all costs associated with its repair and/or replacement. 5. SERVICE: Except for daily surveillance checks only such as liquid levels, the Contractor shall be responsible for all routine maintenance (e.g. refrigerant charging, oil changes, replacing filters, lubricating, topping off liquid levels, etc.) for the duration of the rental period. As a minimum, all disposable filters shall be replaced every six months. 6. START-UP: Unless previously performed on the delivery date, on the agreed start-up date the Vendor shall instruct designated Shipyard personnel on how to properly run the equipment to include its operation, control, daily checks, & service contact(s) and shall insure the prior delivery of a set of operating instructions. The Vendor shall start and run the equipment to verify its operability. For multiple sets of comparable equipment with essentially similar operation, the orientation and start-up on a particular type of machine can be accomplished just once regardless of delivery dates. 7. TERMINATION: The Government shall dismantle the equipment (disconnect utilities & remove any government owned fittings) and provide a stowage location convenient for Contractor pick-up. The Government will notify the Contractor as to when the equipment is released and available. The last day of the rental period shall be the next normal workday that the equipment is available for Contractor pick-up after notification. The Government can provide forklift services during normal work hours for placing the equipment onto the Vendor’s transport. The Vendor shall be responsible for transportation. C GENERIC FEATURES (applicable to any machine) 1. COLOR: Because the rental equipment will be used at a nuclear naval shipyard with radiological controls, the colors yellow and magenta are specifically prohibited and such colors will neither be painted nor displayed (not even stickered) on any rental equipment. 2. CONSTRUCTION: Each machine shall be capable of continuous unmanned operation while exposed to the elements and ambient conditions. The equipment shall meet state and federal requirements, be modular in design for compactness, portable for transport, and ruggedly constructed for an industrial environment. Multiple machines of the same type and capacity shall be of similar design and construction. Each machine shall be factory assembled and factory tested within the last ten years. 3. DOCUMENTATION: Documentation will be located with the equipment, preferably via a water proof case, affixed to each machine. Minimally, the documentation will consist of: (a) Technical Instruction(s) such as an Operations & Maintenance Manual, Controls Manual, and/or Electrical Manual with Schematic; (b) instructions on how to Lift & Handle the equipment with its padeye(s) Certification; (c) government Contract Number to include a copy of the Contract and/or this rental Specification; (d) unless part of the technical instruction, simple Operating Instructions; and (e) point of contact with telephone number for requesting repair. 4. ELECTRICAL: There will not be a separate fee for a power chord / extension nor should extra cable be provided. The Shipyard will electrically connect the rental equipment to the appropriate power source and, if necessary, the Shipyard will also furnish and install a suitable power cable / extension. All electrical components shall conform to NEMA standards. Each machine shall require only one source of electrical power. The nominal power required shall be either 120 volt AC / single phase / 60 hertz or 460 volt AC / 3 phase / 60 hertz. The type of electrical power to be provided to each machine (voltage & amperage) must be clearly indicated on the outside of the equipment, readily detected, and collocated with any other electrical information and not identified on a separate decal. At least one week prior to delivery, the Vendor shall initiate contact with the E&P Dept. Technical Liaison with the following details: (a) electrical power type (i.e. voltage & amperage); (b) electrical connection type (e.g. wire size range for a terminal or mating part number for a connector / lug); (c) recommended capacity for the electrical source; and (d) whether or not the equipment is furnished with over-current protection. 5. LIFTING & HANDLING: Recently, this aspect has come under close scrutiny because of several accidents in the maritime industry. PLEASE NOTE: The precise weight of each machine to include its base support shall be prominently displayed. No exceptions. Each machine shall be firmly attached to a single rigid steel frame with both multiple slots for forklift handling and lifting padeye(s) (preferably welded) to permit safe single point lift operation using an overhead crane. The design safety factor for each lifting padeye shall be at least five (5) times the machine weight based on ultimate strength. For machines with two (2) or three (3) padeyes evenly spaced, the load can be considered equally distributed among the padeyes. For machines with four (4) padeyes, the padeye strength shall be as if each padeye would lift half ( ) the load. The preference is for multiple padeyes to be aligned in the plane of the lift (i.e. padeyes point towards the center) and to be located above the machine’s center of gravity (CG). If the padeyes are located below the CG, then the machine’s CG shall be accurately indicated as to its position as well as its elevation. The Vendor shall provide certification that the lifting points meet the criteria described above by design (5 to 1 ultimate strength) or by load test (2 to 1 w/ no yield). Such certification along with any other lifting data that might be useful shall be included with the documentation attached to the machine. 6. NOISE: When operating at full speed, the noise level shall be 85 dba (i.e. threshold for hearing protection) or less at six (6) feet from the unit / frame. For equating the noise rating of a particular unit, noise intensity (energy) is cut by half (i.e. reduced by 3 dba) as the distance is doubled. Hence, a noise rating of 88 dba at three (3) feet from the unit is equivalent to a noise intensity of 85 dba at six (6) feet. 7. TEST: The units shall be functionally tested prior to shipment. D SPECIFIC FEATURES 1. DESICCANT DEHUMIDIFICATION UNIT: The desiccant dehumidification unit or dehumidifier will be positioned upstream (pre-treatment accessory) of any temperature conditioning module. a. Capacity: (1) Moisture Removal: Based on ambient conditions of 75 F and 50% RH, the dehumidifier shall be capable of removing moisture to at least the quantity as dictated in Table A assuming a minimum air delivery also as dictated in the same table. As a stand alone unit, the dehumidifier shall be capable of delivering processed air at 0 F dew point or lower when the ambient conditions approach saturation at a temperature of 75 F. (2) Airflow: The dehumidifier shall incorporate a variable speed air-handler for the process air in which at full speed the external Total Static Pressure (TSP) in inches of water gauge (WG) and the airflow in cubic feet per minute (cfm) is at least the values as provided in Table A. b. Construction: The desiccant dehumidification unit shall be a single integrated framed structure manufactured as a complete unit to include all devices, accessories, and fittings necessary to generate and blow very dry air to ancillary mechanical equipment. c.

The reactivation wheel shall be capable of being manually shut-off and still have the blower fan in operation. The variable speed control for the process air fan shall be capable of adjusting the airflow to half or less of the minimal airflow as dictated in Table A. d. Design: The desiccant type dehumidifier shall be manufactured as one complete unit to include all necessary devices such as the desiccant wheel, desiccant driver, reactivation heater, energy control system, motors, air-handlers, filters, and other auxiliary components. The dehumidifier shall be of the non-cycling sorption type with a single desiccant rotary structure. Desiccant wheel shall be either titanium silica gel or lithium chloride. Integrated as part of the desiccant dehumidification unit shall be an air-handler consisting of a centrifugal fan and motor. The unit shall be compatible with any downstream post-treatment accessory (e.g. temperature conditioning modules). The unit shall be designed for continuous operation despite extreme ambient temperatures (i.e. 0 to 100 F). e. GFE (Government Furnished Equipment): Equipment shall not include flexible ducting. Even the interconnecting flexible ducting between the dehumidification unit and the temperature conditioning modules will be furnished by the Government. f. Transition: The processed air outlet piece shall transition to accommodate an 18-inch inside diameter round flexible ducting. g. Supplemental: Air shall be pre-filtered. The dehumidifier shall be delivered with clean (reusable) or new (replaceable) filters. The filters shall be of the correct dimension and in sufficient quantity to fill the design space for the filter rack. Upon delivery, the Vendor shall demonstrate that all filters are clean and in place. D SPECIFIC FEATURES (continued) 2. TEMPERATURE CONDITIONING MODULE: The temperature conditioning (i.e. heating or cooling) module will be positioned downstream (post-treatment accessory) of any desiccant dehumidification unit that may be associated with it. a. Capacity: As a post-treatment accessory, the temperature conditioning module shall allow for airflow from any pre-treatment accessory associated with it, such as a desiccant dehumidification unit, in the volume and static pressure as provided in Table A. (1) Heating: The electric heating module shall have a power heating capacity in kilowatts as indicated in Table A assuming a minimum air delivery also as provided in the same table. The rough approximation used for comparing electrical power in watts to heating power in British thermal units per hour (Btu/h) is 0.3 watts 1 Btu/h (e.g. 150 kw 500k Btu/h). (2) Cooling: Based on a chilled water supply temperature of 45 F and a ΔT of 10 F, the cooling module shall have a minimum cooling capacity as indicated in Table A assuming a minimum air delivery also as provided in the same table. The size of the cooling coil shall allow for a minimum flowrate of at least 2.4 gpm per ton of cooling capacity (assumes ΔT of 10 F). b. Construction: The module shall be a single integrated framed structure manufactured as a complete unit to include all devices, accessories, and fittings necessary to allow for very dry air to flow through the unit while being temperature modified without imparting additional moisture. The preference is for no air-handler in either type of module and definitely no fan in the cooling module. c. Control: The unit shall include a permanently mounted control board accessible without opening any panels with temperature thermometer(s) and pressure gauge(s) as necessary for monitoring and control. The unit shall be completely wired for safety, capacity, and operation such as a power/switch system with circuit breakers, manual/automatic controller, motor overload protection, high/low pressure cut-outs, and other essential components. The unit shall be capable of operating in a wide range of loads while the diurnal and seasonal ambient temperatures vary greatly. (1) Heating: The heating module shall have a manual adjustment in at least 4 stages, if not ther-mostatically controlled, capable of delivering processed air f
