B -- TESTING OF PROBES IN A NON-AXIAL FLOW SWIRL WIND TUNNEL SOL DC0071 DUE 043097 POC Ms. Jones at 202-260-9031 WEB: NOT AVAILABLE, NOT AVAILABLE. E-MAIL: NOT AVAILABLE, NOT AVAILABLE. This contract action is for services for which the Government intends to solicit and negotiate with only one source using the Simplified Acquisition Procedures of FAR Part 13 to: perform the attached test matrix on from 8 to 11 probes to be provided by the WAM. Each test will involve a 16-point Method 1 traverse from four ports. Upon completion of testing, the contractor shall ship all of the tested probes to Durham, North Carolina to an address that wil be provided. The contractor shall participate in periodic conference calls with EPA project managers to discuss the testing status. The contractor shall participate in a pre-test meeting for EPA project managers at the contractor's facilities. The purpose of the pre-test meeting is to discuss the test plan and to observe the start of swirl wind tunnel testing. Deliverables/Schedule as follow: A. Task no. 1: Work Plan due: 15 days of receipt of this work assignment B. Task no. 2: Hold pre-test meeting due: Same day as testing starts C. Task no.3: Perform Testing due: 2 weeks after receipt of probes D. Task no. 4: Data Analysis and Report Preparation -- Interim QA'd data 2 weeks after testing -- Final QA'd data 4 weeks after testing -- Draft technical memorandum 6 weeks after testing -- Final technical memorandum 8 weeks after testing E. Task no. 5: Participate in weekly conference calls.

These previous tests must have been at yaw angles of 10 0, 20'. and O' and velocities of 50, 70 and 90 feet per second. Criterion #2: Contractor must have access and capability of testing in a wind tunnel capable of creating swirl flow conditions at controllable, pre-set anoles of yaw and pitch. (Note: The flow within the tunnel must display the indicated yaw and pitch characteristics. It is not acceptable to sli-nply orient the probes at pre-set angles to the flow stream in a wind tunnel where the flow is axial.) At a minimum, the now in the tunnel must be able to be pre-set at separate settings of approximately 10 degrees, 20 and 30 degrees yaw, and 10', 20, and 30 degrees pitch. Criterion #3: The total axial velocity in the tunnel must be able to be held over a range from 50 through 90 feet per second and be able to be verified to within + 2.0 fps by the pressure drop across the venturi. Criterion #4: Contractor must be capable of complying with the attached statement of work. A statement confirming this ability si-ned by an authorized representative of the contractor sMI be sufficient evidence of capability. The above criteria must be met before submitting packages to: US EPA; 401 M Street, SW; Bid and Proposal Room -- 300 Fairchild; mail code 3803F; Washington, DC 20460 -- Attn: Ms. Nel Jones -- Fax at 202-260-1929.
