(c) The Administrative Dispute Resolution Act (ADRA) of 1996, as amended, 5 U.S.C. 571, et seq., authorizes and encourages agencies to use mediation, conciliation, arbitration, and other techniques for the prompt and informal resolution of disputes, and for other purposes. CBCA guidance on ADR may be obtained at http://www.gsbca.gsa.gov/CBCA-17712-v1-CBCA_ADR_INFORMATION.pdf or from the CBCA upon request. ADR procedures may be used—

(2) Prior to the submission of a claim; and

(3) In resolution of a formal claim.
