Architecture Data

The Department of Defense Architecture Framework (DoDAF) is the overarching, comprehensive framework and conceptual model for architectural descriptions developed within the DoD. This framework helps Department of Defense (DoD) managers at all levels make effective decisions by ensuring the sharing of consistent and common information across the Department, Joint Capability Areas (JCAs), missions, components, and programs. The DoDAF helps the DoD Chief Information Officer (CIO) develop and maintain architectures required by the Clinger-Cohen Act. It also fulfills guidance from the Office of Management and Budget (OMB) and other Departmental directives and instructions.


Architect-Engineering Contracting

The Federal Acquisition Regulation defines Architect-Engineering (A-E) Services as:


  1. Professional services of an architectural or engineering nature, as defined by State law, if applicable, that are required to be performed or approved by a person licensed, registered, or certified to provide those services;
  2. Professional services of an architectural or engineering nature performed by contract that are associated with research, planning, development, design, construction, alteration, or repair of real property; and

    Those other professional services of an architectural or engineering nature, or incidental services, that members of the architectural and engineering professions (and individuals in their employ) may logically or justifiably perform, including studies, investigations, surveying and mapping, tests, evaluations, consultations, comprehensive planning, program management, conceptual designs, plans and specifications, value engineering, construction phase services, soils engineering, drawing reviews, preparation of operating and maintenance manuals, and other related services.

Buy American Statute

The Buy American statute (formerly the Buy American Act, 41 U.S.C. § 10a–10d) was passed by U.S. Congress in 1933. The purpose of the Buy American statute is to provide preferential treatment for domestic sources of supplies, manufactured goods, and construction material for public use unless a specific exemption applies. The statute requires the federal government to purchase domestic supplies for use in the United States, if— (a) The supply contract exceeds the micro-purchase threshold; or (b) The supply portion of a contract for services that involves the furnishing of supplies exceeds the micro-purchase threshold. In determining what are domestic goods, the place of mining, production, or manufacture is controlling.  The Buy American statute has separate provisions for supply contracts and construction contracts, and applies to small business set-asides.



Construction Contracting

The Federal Acquisition Regulation defines Construction as:


"Construction" means construction, alteration, or repair (including dredging, excavating, and painting) of buildings, structures, or other real property. For purposes of this definition, the terms "buildings, structures, or other real property" include, but are not limited to, improvements of all types, such as bridges, dams, plants, highways, parkways, streets, subways, tunnels, sewers, mains, power lines, cemeteries, pumping stations, railways, airport facilities, terminals, docks, piers, wharves, ways, lighthouses, buoys, jetties, breakwaters, levees, canals, and channels.


Construction does not include the manufacture, production, furnishing, construction, alteration, repair, processing, or assembling of vessels, aircraft, or other kinds of personal property (except that for use in subpart 22.5, see definition at 22.502)."



Contract Modifications and Changes

Contract modification is a generic term meaning any written change in the terms and scope of the contract. The terms modification and change are often used interchangeably.


Engineering Cost Estimation Method

Derived by summing detailed cost estimates of the individual work packages and adding appropriate burdens. Usually determined by a contractor's industrial engineers, price analysts, and cost accountants. The engineering cost estimating method is one of the four cost estimation methods recommended by the Office of Cost Assessment and Program Evaluation (CAPE).


Government Property

"Government Property" means all property owned or leased by the Government. Government property includes both Government-furnished property and contractor-acquired property (FAR 52.245-1). The FAR provides definitions for the various types of property that are considered to be Government Property and they are described below.


Indirect Contractor Costs

An indirect cost is any cost not directly identifiable with a single, final cost objective, but identified with two or more final cost objectives or an intermediate cost objective. A grouping of indirect costs be a defense contractor is often referred to as an indirect cost pool. According to FAR Part 31.001, a cost objective is a function, organizational subdivision, contract, or other work unit for which cost data are desired and for which provision is made to accumulate and measure the cost of processes, products, jobs, capitalized projects, etc.


Value Engineering (VE) and Value Engineering Change Proposals (VECP)

A Value Engineering Change Proposal (VECP) is a proposal submitted by a contractor under the Value Engineering (VE) provisions of the Federal Acquisition Regulation that, through a change in the contract, would lower the project's life-cycle cost to DoD. This contract change requirement can be the addition of the VECP to the contract, with attendant savings. VECPs are applicable to all contract types, including performance based contracts.
