A prototype OT under 10 U.S.C. § 4022 is available only for a qualifying prototype project. The current construction-specific pilot is limited to prototyping the design, development, or demonstration of new construction techniques or technologies for improving military installations or facilities. Routine construction of barracks, roads, hangars, utilities, or other facilities normally remains a FAR-based procurement unless a specific statutory authority and the project facts support a different instrument.
OTA and OT mean the same thing here
“OTA” is common acquisition shorthand for an other transaction. The statute and current Department of Defense guidance generally use “other transaction” or “OT.” In this article, OTA and prototype OT refer to the same statutory family, not to a separate construction contract type.

The distinction matters because a FAR contract and a prototype OT derive their authority from different legal frameworks. FAR and DFARS rules govern procurement contracts. Section 4022 authorizes qualifying prototype projects through an agreement whose terms are shaped by the statute, agency policy, and the negotiated arrangement. Calling an instrument an OTA does not, by itself, answer whether construction labor rules, competition requirements, funding restrictions, ethics provisions, or other federal laws apply.

What a FAR-based construction contract does
A FAR-based construction contract is a procurement contract for acquiring construction under the federal acquisition system. The solicitation, evaluation, award, clauses, administration, payment, changes, labor standards, and closeout are handled under applicable FAR provisions, DFARS provisions, statutes, and the contract’s own terms.
#1 Best Overall
For ordinary military construction, the government can describe a required facility or civil work, compete the requirement when competition is required, award a contract, and administer performance through the established construction-contract framework. The exact rules vary with the acquisition method, funding source, contract type, dollar value, and the work being bought. “FAR contract” therefore describes the procurement framework, not one universal set of clauses or one standard design.
A FAR-based contract can also include nonconstruction work. When that happens, the government must determine whether a construction portion is covered by the construction wage rules in FAR 22.402 and whether it is physically or functionally separable from the other work.
What a prototype OT under 10 U.S.C. § 4022 does
Section 4022 is a statutory authority for qualifying DoD prototype projects directly relevant to enhancing mission effectiveness or improving platforms, systems, components, or materials. The statute identifies examples such as proof-of-concept work, a model or process, reverse engineering to address obsolescence, a pilot or novel commercial-technology application for defense purposes, agile development, and creating or demonstrating operational utility.
A prototype OT is therefore a means of developing or demonstrating something new, not simply a less formal way to buy a completed facility. The government and participants negotiate the agreement’s milestones, deliverables, intellectual-property terms, payment structure, data rights, inspection rights, security provisions, and remedies within the boundaries of the statute and applicable policy.
The DoD OT Guide, Version 2.0 (July 2023), is policy guidance rather than a replacement for the statute. An accessibility-updated PDF was posted in July 2025. The agreement officer still has to analyze the current law and the facts of the proposed project.
The construction-specific pilot is deliberately narrow
Current preliminary text of 10 U.S.C. § 4022(i), identified by the Office of the Law Revision Counsel as in effect on September 9, 2026, permits DoD or a military department to establish a pilot for prototype projects directly relevant to the design, development, or demonstration of new construction techniques or technologies to improve military installations or facilities.
Rank #2
That language focuses on the novelty being prototyped. A project does not qualify merely because its eventual product is a military building or because the customer is a military department. The proposed work must be connected to prototyping a new technique or technology and must satisfy the other applicable Section 4022 conditions.
| Current pilot feature | What the statute says | Practical meaning |
|---|---|---|
| Project count | No more than two prototype projects may begin per fiscal year, except the limit does not apply to projects carried out to repair a facility. | The authority is a bounded pilot, not an open-ended construction vehicle. |
| Aggregate value | Transactions under the pilot are capped at $300 million in aggregate value. | The cap is a legal limit, not evidence of a typical project size or available budget. |
| Permitted funding | The statute permits military construction, operation and maintenance, or research, development, test and evaluation funds, notwithstanding specified provisions in the statute. | Funding eligibility must be checked against the particular project and approvals; the authority does not eliminate normal fiscal controls. |
| Termination | The pilot authority terminates on September 30, 2030, subject to the statutory exception stated in the current text. | A project planned after that date requires confirmation that authority remains available under the applicable exception or later law. |
The current preliminary text should be used for current limits. The 2023 edition contains older facility-pilot language that differs from the current version and should not be quoted as if it were current law.
Side-by-side comparison
| Issue | FAR-based construction contract | Prototype OT under Section 4022 |
|---|---|---|
| Primary purpose | Procure construction or construction-related performance under acquisition rules. | Develop, demonstrate, or validate a qualifying prototype; the facility pilot addresses new construction techniques or technologies. |
| Fit for ordinary work | Generally suited to routine construction requirements when the agency is buying a defined facility or civil work. | Not a blanket route for routine barracks, roads, hangars, utilities, or facility construction. |
| Governing framework | FAR, applicable DFARS clauses, statutes, solicitation terms, and contract clauses. | Section 4022, other applicable law, DoD policy, and negotiated agreement terms. |
| Competition | FAR competition framework applies, subject to authorized exceptions. | Prototype selection and any later production path depend on statutory conditions, the agreement, and documentation. |
| Construction labor | FAR 22.402 supplies rules for covered construction and certain segregable construction portions. | The label “OT” does not decide labor obligations; the instrument, work, statute, and agreement require separate analysis. |
| Funding and approvals | Determined under the acquisition, appropriations, and construction rules applicable to the contract. | Section 4022 identifies pilot funding options and limits, while project-specific thresholds and approvals still apply. |
| Transition to production | Handled through the contract and applicable competition procedures. | A follow-on production contract or transaction may be authorized only when statutory and agreement conditions are met. |
These columns are not perfectly symmetrical. There is no single universal “FAR construction contract,” and Section 4022 OTs vary by project type, value, participants, and arrangement.
How to test whether a proposed facility project fits the OT pilot
- Define the thing being prototyped. Identify the new construction technique or technology, the technical uncertainty, and the demonstration objective. A conventional design-bid-build facility with no new technique is difficult to characterize as a prototype merely because it is innovative in a general sense.
- Connect the work to a military installation or facility. Explain how the prototype would improve an installation or facility and what evidence the government expects from the demonstration.
- Check the broader Section 4022 purpose. The project must remain directly relevant to enhancing DoD mission effectiveness or improving the systems, components, materials, or other purposes covered by the statute.
- Confirm the participant and teaming facts. Eligibility, nontraditional defense contractor participation, small-business involvement, and any required cost-sharing or approval findings depend on the particular statutory pathway and agreement.
- Check value, fiscal-year count, and sunset. Apply the two-project annual limit, the $300 million aggregate pilot cap, the repair exception, and the September 30, 2030 termination date in the current text.
- Map funding and approvals. Determine whether military construction, operation and maintenance, or research, development, test and evaluation funds are legally available and obtain the approvals required for the project and transaction.
- Write the agreement around measurable prototype outcomes. Set technical milestones, acceptance criteria, testing, data and intellectual-property rights, security requirements, payment triggers, government access, and remedies before award.
- Decide what happens after the demonstration. If a production follow-on is contemplated, include the required provision and document how the statutory conditions will be met; do not assume that a successful demonstration automatically creates a production award.
Why FAR 22.402 still matters when the work is not labeled a construction contract
FAR 22.402 applies construction wage requirements to construction work performed at a particular site, subject to the subpart’s terms. Covered work can include certain demolition and removal, on-site manufacture or fabrication connected with construction, and painting of public buildings or public works. The rule also excludes specified off-site manufacturing and construction so closely related to research, experiment, and development that it cannot be performed separately.
The regulation addresses mixed contracts as well. When a supply, service, research-and-development, or other nonconstruction contract includes construction, the subpart applies to that construction only under stated conditions. The work must involve a public building or public work, amount to a substantial portion above the applicable statutory threshold, and be physically or functionally separate and capable of being performed on a segregated basis. Incidental or inseparable construction is treated differently under the regulation.

FAR 22.402 is a FAR subpart governing construction wage requirements; it does not by itself decide every OT’s labor treatment. For an OT, the government must examine the agreement, the work actually performed, the statutory authority, and any other applicable labor or wage law. A project team should document that analysis instead of assuming either that all FAR rules apply or that none do.
Rank #3
Competition and follow-on production
Section 4022 permits a prototype OT to provide for a follow-on production contract or transaction. A follow-on may be awarded without competitive procedures when the prototype selection used competitive procedures and the participants successfully completed the prototype. The Department has a role in determining successful completion, and the agreement must support the planned transition.
DFARS 206.001-70 supplies a competition exception for certain follow-on production contracts for products developed under Section 4022 prototype OTs. It requires documentation from the agreements officer and refers to the requirement that the OT provide for follow-on production and satisfy the applicable statutory conditions.
- A production option should be considered during prototype planning, not added after the fact as an assumption.
- The selection record must show the competition or other authorized basis used for the prototype.
- Completion must be documented against the prototype’s technical and contractual requirements.
- The follow-on instrument still needs the required approvals, funding, scope, and terms.
- A successful prototype does not guarantee production, a specific quantity, or a noncompetitive award.
Funding, approvals, and compliance are not optional details
The pilot’s ability to use military construction, operation and maintenance, or research, development, test and evaluation funds does not convert those appropriations into unrestricted OT money. The project must fit the purpose and timing of the appropriation, and the transaction must satisfy Section 4022’s applicable thresholds, approvals, and other conditions.
The agreement should identify who has authority to approve the transaction, what technical and business findings support the prototype determination, how value is calculated for the pilot cap, and how the agency will monitor performance. Security classification, export controls, intellectual-property rights, cybersecurity, audit access, records, conflicts of interest, and ethics requirements should be addressed according to the facts and applicable law.
The statute itself treats an agreement under Section 4022 as a federal agency procurement for specified procurement-ethics requirements. That provision is one reason the broad statement “OTAs are exempt from the FAR” is misleading. An OT differs from a procurement contract, but it is not outside every federal requirement.
Common misconceptions
“Any military facility can be built through an OTA.”
No. The current facility pilot is for prototyping new construction techniques or technologies. The end use being a military facility is not enough.
“An OTA is simply a FAR contract with fewer clauses.”
No. The legal authority, purpose, competition analysis, negotiated terms, and compliance review are different. An agreement may omit or tailor clauses that would appear in a procurement contract, but the parties must identify which statutory and regulatory requirements still apply.
“FAR 22.402 never applies to an OT.”
That conclusion cannot be drawn from the instrument’s name. FAR 22.402 addresses covered construction work and segregable construction portions. The project team must analyze the actual OT and work rather than rely on a categorical answer.
“A prototype OT guarantees a later production award.”
No. Follow-on production depends on the prototype’s selection method, successful completion, agreement language, documentation, funding, approvals, and other statutory conditions.
“The statutory dollar cap is a recommended project budget.”
No. The $300 million figure is an aggregate legal limit for the pilot’s transactions, not a normal price, savings estimate, or performance benchmark.

Routine barracks replacement
A requirement to replace barracks using established designs and conventional materials is ordinarily a construction procurement requirement. The fact that the customer is a military department does not create a prototype. A FAR-based contract is the familiar route unless the requirement is redesigned around a genuine, statutorily eligible construction-technology prototype.

Demonstration of a new facility-construction system
A project that tests a novel construction technique at an installation, has defined technical uncertainty, and measures whether the technique improves facility performance may fit the Section 4022(i) pilot if all statutory limits, funding rules, approvals, and agreement requirements are met. The agency must still decide how the demonstration work, site work, labor requirements, and any later production will be administered.
Best Value
Research project with incidental site work
A research-and-development effort may require a small amount of site preparation or installation work. FAR 22.402’s treatment of incidental, inseparable, or segregable construction becomes important. The government should document whether the construction can be separated, whether it is substantial, and which labor requirements apply rather than assuming that the research label controls.
Repair of an existing facility
The current pilot’s project-count limit does not apply to projects carried out to repair a facility. That exception does not eliminate the other statutory requirements, the $300 million aggregate cap, funding rules, approvals, or the need to show that the work is a qualifying prototype involving new construction techniques or technologies.
What the acquisition file should explain
- The operational problem and the specific construction technique or technology to be prototyped.
- Why the project is directly relevant to improving a military installation or facility and to the Section 4022 prototype purpose.
- The proposed participants, roles, subcontracting approach, and any required eligibility findings.
- The value calculation, fiscal-year project count, repair exception analysis, funding source, and approval chain.
- The competition method used for selecting the prototype and the rationale for any authorized alternative.
- The treatment of site work, demolition, fabrication, painting, wages, safety, and other construction-related obligations.
- Milestones, tests, acceptance criteria, data rights, intellectual-property terms, security requirements, payment, changes, disputes, termination, and audit provisions.
- Whether a follow-on production path is included, and the evidence required to establish successful completion.
- The legal provisions that apply to the agreement, including procurement ethics and any requirements that are not displaced by using an OT.
Current status and limits of the available guidance
The current preliminary Section 4022 text supplies the facility-pilot limits described above. The 2023 statutory edition is useful only for historical comparison because its pilot wording differs. DoD’s OT Guide provides policy orientation, but it does not determine whether a particular construction proposal qualifies or supply a universal clause package.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsPublic materials do not establish which DoD components currently operate the facility-prototyping pilot, provide a complete list of awards, or prescribe the clauses for every project. Those facts are implementation-specific. A contracting office, legal counsel, and program team must review the current statute, policy, funding, and proposed agreement before selecting an instrument.
Bottom line for project teams
Use a FAR-based construction contract when the government is buying ordinary construction under the established procurement system. Consider a prototype OT only when the project is genuinely a Section 4022 prototype and, for facility work, fits the narrow pilot for new construction techniques or technologies. Treat labor rules, funding, ethics, approvals, competition, and follow-on production as separate analyses. The OT label can support a different acquisition strategy, but it cannot turn routine military construction into a prototype or provide a blanket exemption from federal requirements.
