Code of Federal Regulations Title 48. Federal Acquisition Regulations System 48.1511.011-74 Work assignments

(a) Policy. When issuing work assignments, the independent government cost estimate shall not be released to the contractor. In most cases the Contracting Officer (CO) should authorize the contractor to expend only the estimated labor hours necessary to develop the work plan and to initiate preliminary tasks which must be performed before work plan approval can be made. However, in cases where the uncertainties involved in the effort are of such a magnitude that there is no reasonable expectation that the contractor can estimate the level of effort required by the tasks, objectives, or outcomes of the requirement, the CO may provide a ceiling level of effort for the entire work assignment at the time of its issuance. In such cases, the specific uncertainties precluding reasonable estimation of the required level of effort on the contractor's part must be documented in the contract file.

(b) Contract Clause. The CO shall insert the contract clause at 1552.211.74, Work Assignments, in cost-reimbursement contracts when work assignments are used.
