The total estimated dollar value of the proposed action is:

4. Authority: FAR 13.106-1(b)(1): For purchases not exceeding the simplified acquisition threshold (SAT), 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: OTT Hydro Met is the only existing brand name that offers the features and configuration necessary to meet all factors relevant to CRREL’s requirement. CRREL currently operates multiple meteorological stations in remote locations that deploy the same or similar sensors, dataloggers, and hardware as the OTT HydroMet sourced equipment. CRREL has invested significant effort to develop the software programming for controlling these meteorological stations, the hardware required to operate these stations in remote and austere environments (installation tower, sensor mounts, power supply, communication cabling, etc), communication protocols for telemetering the collected data back to USACE database infrastructure, along with the data ingest infrastructure (database, servers, real-time data display) required for data storage and dissemination. CRREL requires the exact brand name and model sensors and hardware as outlined below in order to best optimize these previous developments and existing data ingest infrastructure. Sourcing alternative sensors, dataloggers, and/or installation hardware would require CRREL to design new software and hardware solutions that are compatible with these different products, which would place unnecessary time and cost requirements on the team executing the project. Furthermore, these delays would cause project failure because of the significant amount of time
