- Description
- This is a combined synopsis/solicitation for commercial items or services prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This solicitation is issued as a Request for Quotations (RFQ), solicitation number F4BWN08120A002, in accordance with FAR Parts 12 & 13. STATEMENT OF WORK TO DESIGN A REPLACEMENT CONTROL SYSTEM FOR THE USAFA TRISONIC WIND TUNNEL 1.0 PURPOSE. The purpose of this effort is to propose a design to upgrade/replace the obsolete system for controlling the Trisonic Wind Tunnel located in Building 2410, Aeronautics Laboratory, United States Air Force Academy. 2.0 BACKGROUND. The subject control system is part of the permanently installed support equipment for the Aeronautics Laboratory's Trisonic Wind Tunnel (TWT). The Facility is used for cadet instruction and aeronautics research. The TWT is powered by air stored in large tanks pressurized to 600 psig. The primary parameters that must be controlled are 1) the pressure in the stilling chamber at the upstream end of the wind tunnel and 2) the position of the model support system in the wind tunnel test section. The present control system was installed in 1988, and consists of a Moog chassis containing a series of signal conditioners, controllers and amplifiers, and an Allen-Bradley programmable logic controller (PLC). These devices control hydraulic valves that open or close the pressure control valves and move the model support mechanism. The PLC also serves as an interlock to prevent operation of the wind tunnel unless required conditions are satisfied. The control system is still functional, although at least one amplifier has failed affecting a pressure display. The existing system is based on obsolete analog technology and requires extensive manual tuning via multiple potentiometers for the system to function as desired. 3.0 SCOPE. The contractor shall perform a thorough review of the existing control system and produce a document illustrating the required function of a control and interlock system for the wind tunnel. This must include: 1) control of the stilling chamber pressure, 2) position of the model in the test section, 3) manual control of all operator-controllable features, 4) an interlock to prevent operation of the wind tunnel unless all systems are operable and in the proper state, 5) systems to ensure shutdown of the wind tunnel in the event of power failure, loss of hydraulic pressure, emergency stop or excessive stilling chamber pressure, and 6) an interlock system to include physical barriers or warning systems to prevent operation of the tunnel if personnel are in potentially hazardous locations. The contractor shall then recommend hardware and software as appropriate to fully build and install a control system capable of performing these functions and facilitating future control features. It is desirable to have some level of communication between the data acquisition systems and the wind tunnel control systems. For example, if the aerodynamic loads on a force balance measured by the data acquisition system exceed the recommended maxima, the model positioning system should reduce the angle of attack to prevent damage to the equipment. These potential interfaces will be coordinated with Aeronautics Laboratory personnel. 4.0 GENERAL REQUIREMENTS 4.1 Conditions of Work: 4.1.1 The contractor shall perform this work in a manner which will minimize the disruption of normal Air Force Academy operations. 4.1.2 The area of work shall be restricted to Rooms 113, A-10, and A-11 of Building 2410, Aeronautics Laboratory. 4.1.3 Parking of the contractor's vehicles shall be restricted to the parking lot south of Building 2410, and specifically to the spaces designated by the Contracting Officer's representative at the site. The company’s name shall be prominently displayed on all contractor's vehicles parked in the designated spaces. 4.1.4 The contractor may use reasonable required amounts of electricity and water from existing outlets and lines without charge. 4.1.5 The contractor shall comply with all applicable Air Force and USAF Academy regulations pertaining to safety, traffic control, and fire prevention. 4.1.6 The contractor's working hours shall be between 7:30 AM and 4:30 PM, with no work on weekends or federal holidays. Permission to work at times other than those specified shall be obtained from the Contracting Officer at least 5 working days in advance. 4.2 Transportation: The contractor shall provide all transportation necessary for travel of personnel and shipment of parts to and from the Air Force Academy. 5.0 TECHNICAL REQUIREMENTS 5.1 The contractor shall thoroughly examine the existing control system and associated documentation. A reasonable number of test runs may be conducted to demonstrate the control system function and allow collection of data as necessary. 5.2 The contractor shall thoroughly document the logic necessary to require all systems to be functional and in proper states before the valves in the high pressure system can be opened. 5.3 The contractor shall thoroughly describe and document the feedback control loop required to maintain the pressure in the stilling chamber within operator-specified limits and control the rise time of the pressure. This must include control signals sent to the existing hydraulic valves that control the actuators opening the valves to the high pressure system. 5.4 The contractor shall thoroughly describe and document the feedback control loop required to maintain the operator-specified angle of attack of models attached to the model positioning system. This must include control signals sent to the existing hydraulic valves that control the position of the mechanism. 5.5 The contractor shall work with Aeronautics Laboratory personnel to consider all potential emergency scenarios (loss of power, loss of hydraulic pressure, etc) and build into the design of the control system features to immediately shut off the wind tunnel in an emergency. 5.6 The contractor shall design an interlock system to provide suitable warning to personnel that the tunnel is ready to run or that any systems are in a potentially hazardous state. 5.7 The contractor shall produce a proposal for a system to include hardware and software to accomplish the design characteristics of the control system and interlock. 6.0 SCHEDULE. All work shall be coordinated through the Contracting Officer's representative at the site and completed no later than 180 days after contract award. The total accumulated downtime of the Trisonic Wind Tunnel for this work shall not exceed 10 business days. 7.0 Basis for Award. a. The Government will award, a single purchase order resulting from this solicitation to the responsible offeror whose offer, conforming to the statement of work (SOW), will be most advantageous to the Government, price and technical acceptability considered. This will be a Lowest Price Technically Acceptable (LPTA) Best Value award. In using the LPTA Best Value approach, the Government intends to award, to an offeror who provides the Air Force a technically acceptable proposal and the best price. The Government reserves the right to conduct discussions if the Contracting Officer later determines them to be necessary. The Government reserves the right to reject any or all offers if such action is in the Government’s best interest. The following factors shall be used to evaluate offers: Factor 1 - Technical Proposal Factor 2 - Price b. Technically Acceptable. Technical Proposals will be graded on a “Pass/Fail” basis. All technically acceptable proposals will be evaluated for price. The Government shall conduct a Technical Evaluation on the Contractor’s Technical Proposal using the three technical subfactors below, assigning a rating of Acceptable or Unacceptable. (1) Offeror proposed deliverables meet the requirements stated in the SOW (Documents, Reports, CDRL items, formats, etc.). (2) Offeror proposed schedules are acceptable. (3) Offeror proposed an approach which sufficiently addressed the technical require-ment and reflects a clear understanding of the requirement. (4) Offer must include summary of technical approach to meet all requirements in Section 5 of Statement of Work. c. Price. This will be a Lowest Price Technically Acceptable (LPTA) Best Value award. Only proposals that are technically acceptable will be considered. The award will be made to the lowest priced, technically acceptable proposal. The Government reserves the right to award without discussion. 8.0 This solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 01-07.
