4. Justification Rationale:

As Campbell Scientific Eddy Covariance CO2/H2O Open-Path Gas Analyzer Systems are currently used by RRRU, it is necessary to obtain the same manufactured equipment to limit scientific variability and ensure scientific integrity.

This is essential for the Long-Term Agro-ecosystem Research (LTAR) network.

5. Determination of Fair and Reasonable Cost:

Fair and Reasonable price will be determined via price comparison, in accordance with FAR 13.106-3 (a)(1), Whenever possible, base price reasonableness on competitive quotations or offers. Price reasonableness will also be determined by comparing the proposed prices to the prices paid for this same purchase last fiscal year under PO #AG- 8KAP-P-14-0028, in accordance with FAR 13.106-3 (a)(2)(ii), Comparison of the proposed price with prices found reasonable on previous purchases.

6. Market Research:

Based on past procurements, it is known that more than one vendor can supply the required products.

7. Actions Taken to Remove Barriers to Competition:

There is a possibility for barriers to be removed if other LTAR networks begin using different equipment, or all the Eddy Covariance open path gas analyzer systems are replaced at one time.
