What contract type does a KO determine when no other type is suitable?

The correct answer is Time and Material Contracts. This contract type is typically utilized when it is not feasible to accurately estimate the extent or duration of the work required, and when it is essential to maintain flexibility in the procurement process.

Time and Material Contracts allow for a combination of reimbursement for direct labor hours at specified hourly rates, along with the reimbursement of materials at cost. This structure is ideal in situations where the exact scope of work cannot be predetermined, such as in research and development projects or when unforeseen complications arise during the performance of the work.

In these scenarios, the contracting officer (KO) identifies that other contract types, like fixed-price or cost-reimbursement contracts, may not be suitable due to inherent risks or uncertainties in timely delivery or defined output, thus opting for a more adaptable and responsive approach. This contract type supports the need for flexibility in managing workloads, especially when project requirements may change or evolve.
