＝＝＝＝
When issues arise in performance of a federal contract, a contractor may seek redress from the government by filing a claim with the contracting officer. However, commencing such a claim may result in an exercise of patience and waiting by the contractor.

The Contract Disputes Act, as a jurisdictional hurdle for claims over $100,000, requires a contractor to submit a “certified claim” to the agency. The CDA also requires the contracting officer, within sixty days of receipt of a certified claim, to issue a decision on that claim or notify the contractor of the time within which the decision will be issued.
