(a)(1) Supplies and services. The contracting officer shall insert the clause at 52.249-8, Default (Fixed-Price Supply and Service), in solicitations and contracts when a fixed-price contract is contemplated and the contract amount is expected to exceed the simplified acquisition threshold. The contracting officer may use the clause when the contract amount is at or below the simplified acquisition threshold, if appropriate (e.g., if the acquisition involves items with a history of unsatisfactory quality).
