Brand Name Determination Honeywell Accelerometer

1. Contracting Activity: The ERDC Contracting Office (ECO) is located at the U.S. Army

Engineer Research and Development Center (ERDC), 3909 Halls Ferry Road, Vicksburg, MS 39180-6199.

2. Description of Action: This determination seeks approval to award a new Firm Fixed Price

(FFP) contract on a brand name basis pursuant to procedures at Federal Acquisition Regulation (FAR) 13.106-1(b)(1)(i) to procure twenty-five (25) Honeywell Q-Flex QA-650 Single Axis Quartz Accelerometers.

3. Description of the product required to meet the agency’s needs: The Geotechnical and

Structures Laboratory (GSL) Structural and Mechanics Branch (SMB) requires the Honeywell Q-Flex QA-650 Single Axis Quartz Accelerometers. Accelerometers for this project must meet the following specifications:

Performance Characteristics

Performance Input Range ±30 g Bias <15 mg One-year Composite Repeatability <2500 µg Temperature Sensitivity <100 µg/°C Scale Factor 1.20 to 1.40 mA/g One-year Composite Repeatability <2500 µg Temperature Sensitivity <200ppm/°C Axis Misalignment <15000 µrad Vibration Rectification <100 (50-500 Hz) µg/g2rms Intrinsic Noise [g-rms] <3000 (0-10,000 Hz) Environmental Operating Temperature Range -55 to +96°C Shock 100 g Vibration Peak Sine 25 g @ 30-500 Hz Resolution/Threshold < 10 µg Bandwidth ˃300 Hz Thermal Modeling Yes Electrical Quiescent Current per Supply <16 Ma Quiescent Power <480 mW @ ±15 VDC Input Voltage ±13 to ± 18 VDC Physical Weight 51 Nominal, 65 Max grams Diameter below mounting surface Ø 1.045 ±0.005in.

Height – bottom to mounting surface 0.617 in. Max Case Material 300 Series Stainless Steel

Shipping shall be FOB destination and associated costs included in the quote.

4. Authority Cited: Due to the Independent Government Estimate (IGE) for this requirement is less than the Simplified Acquisition Threshold (SAT), contracting without providing for full and open competition is authorized under 41 U.S.C. 1901, as implemented in Federal Acquisition Regulation (FAR) 13.106-1(b), Soliciting from a single source (1) For purchases not exceeding the simplified acquisition threshold (i) Contracting officers may solicit from one source if the contracting officer determines that the circumstances of the contract action deem only one source reasonably available (e.g., urgency, exclusive licensing agreements, brand-name or industrial mobilization).

5. Reason for Authority Cited:

Background: The SMB has been tasked with determining the current health and monitoring of concrete hydraulic structures for the USACE and provide performance data that can be used to validate numerical analyses. As part of this research, measured responses from select dams will form the basis for the evaluation of each concrete dams’ fundamental characteristics and key performance indicators that describe existing conditions and performance. The work being performed by SMB requires the Honeywell Q-Flex QA-650 Single Axis Quartz Accelerometers.

Justification: The Q-Flex QA-650 accelerometers offer the capability of capturing and monitoring high-speed data in large civil structures. The QA-650 Accelerometers are being used to determine the current health and monitor concrete hydraulic structures for the Corps of Engineers. Due to the specific capabilities and specifications of these accelerometers, the QA- 650 accelerometers must be used to capture real-time responses from select dams in order to accurately describe exiting conditions, and performance, for replication in developing numerical prediction models. No other accelerometers on market will meet the specifications and capabilities requirement.

6. Efforts to Obtain Competition: This brand name justification will be provided with the solicitation as required by FAR 5.102(a)(6). These items are sold by several different companies, therefore adequate competition is anticipated.

7. Determination that costs will be fair and reasonable: The Independent Government Estimate (IGE), catalog prices, price competition, and the laboratory’s technical representative’s knowledge of the industry will be used to determine if the quoted price is fair and reasonable.

8. Description of Market Research: Based upon market research, it is determined that this requirement is a commercial item, and it is recommended that the required brand name item be competed as 100% set aside to small business. There are other small business resale companies capable of providing the required accelerometer.

9. Contracting Officer Determination: I certify that this justification is accurate and complete to the best of my knowledge and belief.
