Subpart 31.1 - ApplicabilitySubpart 31.1 - Applicability    **Parent topic:**  Part 31 - Contract Cost Principles and Procedures31.100 Scope of subpart.       This subpart describes the applicability of the cost principles and procedures in succeeding subparts of this part to various types of contracts and subcontracts. It also describes the need for advance agreements.31.101 Objectives.       In recognition of differing organizational characteristics, the cost principles and procedures in the succeeding subparts are grouped basically by organizational type; *e.g.,* commercial concerns and educational institutions. The overall objective is to provide that, to the extent practicable, all organizations of similar types doing similar work will follow the same cost principles and procedures. To achieve this uniformity, individual deviations concerning cost principles require advance approval of the agency head or designee. Class deviations for the civilian agencies require advance approval of the Civilian Agency Acquisition Council. Class deviations for the National Aeronautics and Space Administration require advance approval of the Deputy Chief Acquisition Officer. Class deviations for the Department of Defense require advance approval of the Principal Director, Defense Pricing and Contracting, Office of the Under Secretary of Defense for Acquisition and Sustainment.31.102 Fixed-price contracts.       The applicable subparts of  part  31 shall be used in the pricing of fixed-price contracts, subcontracts, and modifications to contracts and subcontracts whenever (a) cost analysis is performed, or (b)a fixed-price contract clause requires the determination or negotiation of costs. However, application of cost principles to fixed-price contracts and subcontracts shall not be construed as a requirement to negotiate agreements on individual elements of cost in arriving at agreement on the total price. The final price accepted by the parties reflects agreement only on the total price. Further, notwithstanding the mandatory use of cost principles, the objective will continue to be to negotiate prices that are fair and reasonable, cost and other factors considered.31.103 Contracts with commercial organizations.       This category includes all contracts and contract modifications for supplies, services, or experimental, developmental, or research work negotiated with organizations other than educational institutions (see  31.104), construction and architect-engineer contracts (see  31.105), State and local governments (see  31.107) and nonprofit organizations (see  31.108) on the basis of cost.                                       (a) 						            The cost principles and procedures in  subpart  31.2 and agency supplements shall be used in pricing negotiated supply, service, experimental, developmental, and research contracts and contract modifications with commercial organizations whenever cost analysis is performed as required by  15.404-1(c).                                          (b) 						            In addition, the contracting officer shall incorporate the cost principles and procedures in  subpart  31.2 and agency supplements by reference in contracts with commercial organizations as the basis for-                                                         (1) 								                Determining reimbursable costs under-                                                                           (i) 										                    Cost-reimbursement contracts and cost-reimbursement subcontracts under these contracts performed by commercial organizations and                                                                              (ii) 										                    The cost-reimbursement portion of time-and-materials contracts except when material is priced on a basis other than at cost (see  16.601(c)(3));                                                                                                           (2) 								                Negotiating indirect cost rates (see  subpart  42.7);                                                            (3) 								                Proposing, negotiating, or determining costs under terminated contracts (see  49.103 and  49.113);                                                            (4) 								                Price revision of fixed-price incentive contracts (see  16.204 and  16.403);                                                            (5) 								                Price redetermination of price redetermination contracts (see  16.205 and  16.206); and                                                            (6) 								                Pricing changes and other contract modifications.31.104 Contracts with educational institutions.       This category includes all contracts and contract modifications for research and development, training, and other work performed by educational institutions (defined as institutions of higher educations in the OMB Uniform Guidance at 2 CFR part 200, subpart A, and   20 U.S.C. 1001).                                       (a) 						            The contracting officer shall incorporate the cost principles and procedures in  subpart  31.3 by reference in cost-reimbursement contracts with educational institutions as the basis for-                                                         (1) 								                Determining reimbursable costs under the contracts and cost-reimbursement subcontracts thereunder performed by educational institutions;                                                            (2) 								                Negotiating indirect cost rates; and                                                            (3) 								                Settling costs of cost-reimbursement terminated contracts (see  subpart  49.3 and  49.109-7).                                                                             (b) 						            The cost principles in this subpart are to be used as a guide in evaluating costs in connection with negotiating fixed-price contracts and termination settlements.31.105 Construction and architect-engineer contracts.       (a) 						            This category includes all contracts and contract modifications negotiated on the basis of cost with organizations other than educational institutions (see  31.104), State and local governments (see  31.107), and nonprofit organizations except those exempted under OMB Uniform Guidance at 2 CFR part 200, appendix VIII (see  31.108) for construction management or construction, alteration or repair of buildings, bridges, roads, or other kinds of real property. It also includes architect-engineer contracts related to construction projects. It does not include contracts for vessels, aircraft, or other kinds of personal property.                                          (b) 						            Except as otherwise provided in (d) of this section, the cost principles and procedures in  subpart  31.2 shall be used in the pricing of contracts and contract modifications in this category if cost analysis is performed as required by  15.404-1(c).                                          (c) 						            In addition, the contracting officer shall incorporate the cost principles and procedures in  subpart  31.2 (as modified by (d) of this section by reference in contracts in this category as the basis for-                                                         (1) 								                Determining reimbursable costs under cost-reimbursement contracts, including cost-reimbursement subcontracts thereunder;                                                            (2) 								                Negotiating indirect cost rates;                                                            (3) 								                Proposing, negotiating, or determining costs under terminated contracts;                                                            (4) 								                Price revision of fixed-price incentive contracts; and                                                            (5) 								                Pricing changes and other contract modifications.                                                                             (d) 						            Except as otherwise provided in this paragraph (d), the allowability of costs for construction and architect-engineer contracts shall be determined in accordance with  subpart  31.2.                                                         (1) 								                Because of widely varying factors such as the nature, size, duration, and location of the construction project, advance agreements as set forth in  31.109, for such items as home office overhead, partners’ compensation, employment of consultants, and equipment usage costs, are particularly important in construction and architect-engineer contracts. When appropriate, they serve to express the parties’ understanding and avoid possible subsequent disputes or disallowances.                                                            (2) 								                "Construction equipment," as used in this section, means equipment (including marine equipment) in sound workable condition, either owned or controlled by the contractor or the subcontractor at any tier, or obtained from a commercial rental source, and furnished for use under Government contracts.                                                                           (i) 										                    Allowable ownership and operating costs shall be determined as follows:                                                                                             (A) 												                        Actual cost data shall be used when such data can be determined for both ownership and operations costs for each piece of equipment, or groups of similar serial or series equipment, from the contractor’s accounting records. When such costs cannot be so determined, the contracting agency may specify the use of a particular schedule of predetermined rates or any part thereof to determine ownership and operating costs of construction equipment (see subdivisions (d)(2)(i)(B) and (C) of this section). However, costs otherwise unallowable under this part shall not become allowable through the use of any schedule (see  31.109(c)). For example, schedules need to be adjusted for Government contract costing purposes if they are based on replacement cost, include unallowable interest costs, or use improper cost of money rates or computations. Contracting officers should review the computations and factors included within the specified schedule and ensure that unallowable or unacceptably computed factors are not allowed in cost submissions.                                                                                                (B) 												                        Predetermined schedules of construction equipment use rates (*e.g.,* the Construction Equipment Ownership and Operating Expense Schedule, published by the U.S. Army Corps of Engineers, industry sponsored construction equipment cost guides, or commercially published schedules of construction equipment use cost) provide average ownership and operating rates for construction equipment. The allowance for operating costs may include costs for such items as fuel, filters, oil, and grease; servicing, repairs, and maintenance; and tire wear and repair. Costs of labor, mobilization, demobilization, overhead, and profit are generally not reflected in schedules, and separate consideration may be necessary.                                                                                                (C) 												                        When a schedule of predetermined use rates for construction equipment is used to determine direct costs, all costs of equipment that are included in the cost allowances provided by the schedule shall be identified and eliminated from the contractor’s other direct and indirect costs charged to the contract. If the contractor’s accounting system provides for site or home office overhead allocations, all costs which are included in the equipment allowances may need to be included in any cost input base before computing the contractor’s overhead rate. In periods of suspension of work pursuant to a contract clause, the allowance for equipment ownership shall not exceed an amount for standby cost as determined by the schedule or contract provision.                                                                                                                                         (ii) 										                    Reasonable costs of renting construction equipment are allowable (but see paragraph (C) of this subsection).                                                                                             (A) 												                        Costs, such as maintenance and minor or running repairs incident to operating such rented equipment, that are not included in the rental rate are allowable.                                                                                                (B) 												                        Costs incident to major repair and overhaul of rental equipment are unallowable.                                                                                                (C) 												                        The allowability of charges for construction equipment rented from any division, subsidiary, or organization under common control, will be determined in accordance with  31.205-36(b)(3).                                                                                                                                                                      (3) 								                Costs incurred at the job site incident to performing the work, such as the cost of superintendence, timekeeping and clerical work, engineering, utility costs, supplies, material handling, restoration and cleanup, etc., are allowable as direct or indirect costs, provided the accounting practice used is in accordance with the contractor’s established and consistently followed cost accounting practices for all work.                                                            (4) 								                Rental and any other costs, less any applicable credits incurred in acquiring the temporary use of land, structures, and facilities are allowable. Costs, less any applicable credits, incurred in constructing or fabricating structures and facilities of a temporary nature are allowable.31.106 [Reserved]31.107 Contracts with State, local, and federally recognized Indian tribal governments.       (a)                    subpart  31.6 provides principles and standards for determining costs applicable to contracts with State, local, and federally recognized Indian tribal governments. They provide the basis for a uniform approach to the problem of determining costs and to promote efficiency and better relationships between State, local, and federally recognized Indian tribal governments, and Federal Government entities. They apply to all programs that involve contracts with State, local, and federally recognized Indian tribal governments, except contracts with-                                                         (1) 								                Publicly financed educational institutions subject to  subpart  31.3; or                                                            (2) 								                Publicly owned hospitals and other providers of medical care subject to requirements promulgated by the sponsoring Government agencies.                                                                             (b) 						            The Office of Management and Budget will approve any other exceptions in particular cases when adequate justification is presented.31.108 Contracts with nonprofit organizations.       Subpart  31.7 provides principles and standards for determining costs applicable to contracts with nonprofit organizations other than educational institutions (see  subpart  31.3), State and local governments (see  subpart  31.6), and those nonprofit organizations exempted under the OMB Uniform Guidance at 2 CFR part 200, appendix VIII (see  subpart  31.2 for the cost principles applicable to nonprofit organizations exempt from the cost principles in the OMB Uniform Guidance at 2 CFR part 200).31.109 Advance agreements.       (a) 						            The extent of allowability of the costs covered in this part applies broadly to many accounting systems in varying contract situations. Thus, the reasonableness, the allocability and the allowability under the specific cost principles at  subparts  31.2,  31.3,  31.6, and  31.7 of certain costs may be difficult to determine. To avoid possible subsequent disallowance or dispute based on unreasonableness, unallocability or unallowability under the specific cost principles at  subparts  31.2,  31.3,  31.6, and  31.7, contracting officers and contractors should seek advance agreement on the treatment of special or unusual costs and on statistical sampling methodologies at  31.201-6(c). However, an advance agreement is not an absolute requirement and the absence of an advance agreement on any cost will not, in itself, affect the reasonableness, allocability or the allowability under the specific cost principles at  subparts  31.2,  31.3,  31.6, and  31.7 of that cost.                                          (b) 						            Advance agreements may be negotiated either before or during a contract but should be negotiated before incurrence of the costs involved. The agreements must be in writing, executed by both contracting parties, and incorporated into applicable current and future contracts. An advance agreement shall contain a statement of its applicability and duration.                                          (c) 						            The contracting officer	is not authorized by this  31.109 to	agree to a treatment of costs inconsistent with this part. For example, an	advance agreement may not provide that, notwithstanding  31.205-20,	interest is allowable.                                          (d) 						            Advance agreements may be negotiated with a particular contractor for a single contract, a group of contracts, or all the contracts of a contracting office, an agency, or several agencies.                                          (e) 						            The cognizant administrative contracting officer (ACO), or other contracting officer established in  part  42, shall negotiate advance agreements except that an advance agreement affecting only one contract, or class of contracts from a single contracting office, shall be negotiated by a contracting officer in the contracting office, or an ACO when delegated by the contracting officer. When the negotiation authority is delegated, the ACO shall coordinate the proposed agreement with the contracting officer before executing the advance agreement.                                          (f) 						            Before negotiating an advance agreement, the Government negotiator shall-                                                         (1) 								                Determine if other contracting offices inside the agency or in other agencies have a significant unliquidated dollar balance in contracts with the same contractor;                                                            (2) 								                Inform any such office or agency of the matters under consideration for negotiation; and                                                            (3) 								                As appropriate, invite the office or agency and the responsible audit agency to participate in prenegotiation discussions and/or in the subsequent negotiations.                                                                             (g) 						            Upon completion of the negotiation, the sponsor shall prepare and distribute to other interested agencies and offices, including the audit agency, copies of the executed agreement and a memorandum providing the information specified in  15.406-3, as applicable.                                          (h) 						            Examples for which advance agreements may be particularly important are-                                                         (1) 								                Compensation for personal services, including but not limited to allowances for off-site pay, incentive pay, location allowances, hardship pay, cost of living differential, and termination of defined benefit pension plans;                                                            (2) 								                Use charges for fully depreciated assets;                                                            (3) 								                Deferred maintenance costs;                                                            (4) 								                Precontract costs;                                                            (5) 								                Independent research and development and bid and proposal costs;                                                            (6) 								                Royalties and other costs for use of patents;                                                            (7) 								                Selling and distribution costs;                                                            (8) 								                Travel and relocation costs, as related to special or mass personnel movements, as related to travel via contractor-owned, -leased, or -chartered aircraft; or as related to maximum per diem rates;                                                            (9) 								                Costs of idle facilities and idle capacity;                                                            (10) 								                Severance pay to employees on support service contracts;                                                            (11) 								                Plant reconversion;                                                            (12) 								                Professional services (*e.g.,* legal, accounting, and engineering);                                                            (13) 								                General and administrative costs (*e.g.,* corporate, division, or branch allocations) attributable to the general management, supervision, and conduct of the contractor’s business as a whole. These costs are particularly significant in construction, job-site, architect-engineer, facilities, and Government-owned contractor operated (GOCO) plant contracts (see  31.203(h));                                                            (14) 								                Costs of construction plant and equipment (see  31.105(d));                                                            (15) 								                Costs of public relations and advertising; and                                                            (16) 								                Statistical sampling methods (see  31.201-6(c)(4).31.110 Indirect cost rate certification and penalties on unallowable costs.       (a) 						            Certain contracts require certification of the indirect cost rates proposed for final payment purposes. See  42.703-2 for administrative procedures regarding the certification provisions and the related contract clause prescription.                                          (b) 						            If unallowable costs are included in final indirect cost settlement proposals, penalties may be assessed. See  42.709 for administrative procedures regarding the penalty assessment provisions and the related contract clause prescription.
