Written by GovTribe AI · Apr 9, 2026

This is a Questions and Answers document addressing inquiries regarding the Portable Patient Transport System (PPTS) prototype procurement under Army Contracting Command-Aberdeen Proving Ground.

The document addresses technical requirements for the PPTS, including system monitoring, glove port specifications, transfer mechanisms, filter specifications, and interoperability requirements with NATO litters and biocontainment systems. Key technical clarifications address HEPA-equivalent filtration performance (99.97% or greater at 0.3 microns), glove port compliance with ASTM F1671 and ASTM D6319 standards, watertight storage container requirements, and system weight constraints (individual components not exceeding 50 lbs; total system not exceeding 200 lbs in stored configuration). The Government emphasizes that Berry Amendment compliance is required for all prototypes and that the system must support transport of mechanically ventilated patients while maintaining biocontainment, with battery backup supporting up to 12 hours of continuous operation through hot-swappable packs and maximum 1-minute power interruptions during swaps.

Procurement details indicate that multiple Prototype Other Transaction (OT) Agreements will be awarded under 10 U.S.C. 4022 authority against Army Open Solicitation W9128Z-25-S-A002. The Government will award up to 15 systems with anticipated Phase III completion by FY29. Offerors must demonstrate credible regulatory pathways to FDA 510(k) clearance and full airworthiness certification by end of Phase III and assert threshold requirement compliance in Solution Briefs. All proposed costs must be reasonable and directly allocable to prototype development, with Government evaluation including FDA clearance support through funding and subject matter expert guidance. The procurement encourages formation of diverse teams involving Non-Traditional Defense Contractors (NDCs) and small businesses, with partnering viewed as favorable but not mandatory.

PPTS

		Question	Answer
	PPTS	Does the system need monitors?	Yes, the anteroom and main room of the system need a monitoring system to alert when there is loss of pressure.
	PPTS	What is the distance between glove ports based on?	Based on user requirements.
	PPTS	What is the rationale behind the number of glove ports?	Will need to prove you can provide the required care.
	PPTS	What is the difference between transport pouch vs pass through port?	Pouch is transfer of items in and out of the system while maintaining negative pressure in the system. Port is more for transfer of cabling.
	PPTS	Could the Government clarify the clinical rationale behind the 14-port desired requirement and whether a solution with fewer glove ports that still allows for comprehensive patient care access would be considered compliant?	See threshold requirement
	PPTS	Can the DoW clarify the intended functional use of the pass‑through ports? Would alternative interface designs that achieve equivalent clinical functionality be acceptable?	We will consider alternative interface designs. Examples of functional pass-through items include vent tubes, IV lines, patient care devices, EKG wires
	PPTS	What types of large items does the DoW intend to transfer through the transfer pouch?	Food, water bottle, medication, absorbant pads, patient comfort items
	PPTS	Will sizing spec be provided with min/max requirements for the utility ports (cables/hoses)?	Yes. See final Statement of Objectives
	General	Could the Government provide or reference the applicable NSN or specifications for the stanchion systems in these platforms so offerors can demonstrate compatibility in their Solution Briefs?	https://www.coemed.org/files/stanags/03_AMEDP/AMedP-2.1_EDA_V1_E_2040.pdf
	General	What is required for Berry amendment compliance?	This is the statute itself. Primary Law (U.S. Code): 10 U.S.C. § 4862 - "Requirement to buy certain articles from American sources; exceptions".
	PPTS	What if our initial deliverable is non-Berry compliant, with the promise that our final version will be?	It is in the best interest of the government for the Prototypes to be Berry Compliant. The prototypes will undergo testing to validate their performance. This testing would need to be replicated in the event of a change in the material composition between prototype and production. The replication of this testing is an unacceptable cost to the Government in both dollars and time.
	PPTS	Is cost for production a factor?	You may be evaluated against the cost you provide, and justification will be required.
	PPTS	What kind of data rights are required?	The government will always want unlimited data rights. Vendors would need to assert their data claims. The SOO and CFS indicate that Government Purpose Rights are the minimum acceptable level.
	PPTS	Could the Government clarify how pre-existing government-funded IP interacts with the Unlimited Rights preference in Section F?	Legal response: Review the criteia as wriiten. “The Government’s strong preference is for Unlimited Rights for all technical data, software, and associated intellectual property developed under this effort.”
	General	Would the anteroom need to be decontaminated?	Yes.
	General	Include disinfection process?	Probably, refer to CFS .
	PPTS	Will a copy of Test Plan, Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report, Vol. 54 No. RR-17, 30 December 2005 be furnished?	No the test plan will not be provided. A copy of the referenced document can be downloaded at https://www.cdc.gov/mmwr/PDF/rr/rr5417.pdf
	PPTS	To clarify the watertight requirements, will the SIS have the requirement of being watertight or only the storage containers?	The storage containers must be watertight. There is no watertight requirement for the system, but must pass the liquid containment requirements.
	PPTS	Specifically, is a Solution Brief acceptable if the offeror demonstrates a credible Phase III path to FDA clearance even if clearance has not yet been initiated?	The solution briefs for FDA marketing authorization and full airworthiness are required by the end of Phase III. The Offerors RSP must demonstrate a credible approach to meeting the project's core objectives. Draft Interface Control Document (ICD); submission of the FDA 510(k) clearance request and performer's status with the FDA 510(k) clearance process.
	PPTS	Could the Government provide its anticipated Phase III timeline?	Anticipated to end by 2FY29
	PPTS	Does the Government anticipate providing any support, such as letters to FDA or access to government-generated test data, to assist performers in achieving clearance?	CPE-CBRND provides support toward achieving clearance in the form of funding and subject matter expert review and guidance and, when allowable and pending negotiation, shares Government-generated test data that may be of use to performers.
	PPTS	Could the required FDA clearance be pursued through this DoW–FDA collaborative pathway?	Performers should respond with their regulatory strategy, including proposed pathway(s), that they believe are appropriate for their device and the indication that CPE-CBRND is seeking.
	PPTS	If human factors engineering studies are required as part of FDA clearance, will the DoW support these studies by providing access to representative users and relevant operational environments?	Yes.
	PPTS	Is the requirement for the filter to be located outside the system vs. inside?	The preference is for the filter to be located outside the system.
	PPTS	Would the Government confirm whether EN1822 H14 certification is an acceptable equivalent to NIOSH P-100 for purposes of this CFS, or whether NIOSH P-100 is a hard certification requirement regardless of demonstrated performance?	The requirement for the exhaust filter is HEPA-equivalent filtration performance of 99.97% or greater at 0.3 microns. In addition, the preference is for a filter in the DoW inventory: https://www.nsnlookup.com/dla/webflis
	PPTS	Would the Government clarify if the intent of the NIOSH P-100 requirement is for the level of particulate filtration effectiveness, or if being oil-proof (i.e. P- vs N- filter rating) is critical for the expected use environment?	The requirement for the exhaust filter is HEPA-equivalent filtration performance of 99.97% or greater at 0.3 microns. In addition, the preference is for a filter in the DoW inventory: https://www.nsnlookup.com/dla/webflis
	General	Will a filter system with ASZM-TEDA and HEPA filtration be acceptable for use instead of the NIOSH P-100 certified filters?	The preference is not to have carbon in the filter. The requirement for the exhaust filter is HEPA-equivalent filtration performance of 99.97% or greater at 0.3 microns; however, inlet filters shall have a a minimum MERV rating of 5 as stated in the SOO. In addition, the preference is for a filter in the DoW inventory: https://www.nsnlookup.com/dla/webflis
	PPTS	Are projects considered funded requirements? Or will they be impacted by continuing resolutions?	They are funded as they can be.
	General	Will funding be provided for program management of this opportunity in addition to purchasing of prototypes?	Yes, funding will be provided as required to execute the agreement.
	General	If selected for funding, what categories of offeror’s product development expenses are allowed? For example, engineering & design changes to meet military requirements, prototype costs, tooling costs, testing needed for FDA 510K (or De Novo) application, FDA-consultant fee, and marketing expenses.	As this effort will be awarded as an Other Transaction (OT) agreement, it is not subject to the specific cost principles of the Federal Acquisition Regulation (FAR). However, all proposed costs must be considered reasonable and directly allocable to the work required to perform the prototype project as defined in the Statement of Objectives (SOO). The Government will evaluate proposed costs as part of its overall best-value determination.
	Common	What is the rationale between modifications of system vs new systems?	This is the requirement from the Service.
	PPTS	Does there need to be Interoperability between the BIQ programs systems?	Yes, SIS will be in BCIS, and on a ship. PPTS will be on a litter then brought into the BCIS and SIS.
	PPTS	Would the ppts need to be tested with litter or does the system need to be rigid?	System must be compatible with NATO litter at a minimum.
	PPTS	Could the Government clarify whether the system is expected to have a universal connection mechanism compatible with all listed litter types, or whether compatibility is demonstrated on a per-litter basis?	Per-litter basis, but universal would be viewed more favorably.
	PPTS	Additionally, is litter compatibility intended to replace the system having its own independent base structure, or is it expected to function both as a standalone unit and in conjunction with the listed litters?	Design considerations are up to the vendor, but system must be compatible with NATO litter at a minimum.
	PPTS	Is flame resistance required for fabric shelter?	Not at this time.
	PPTS	Is there a requirement for the type of gloves?	Glove port gloves shall meet or exceed the requirements of ASTM F1671 and ASTM D6319. Glove port gloves shall provide sufficient dexterity for caregivers to perform clinical tasks such as operating medical equipment, administering medication, and adjusting patient monitoring devices.
	General	Is there a requirement for protection of the care giver?	No.
	General	Is partnering preferred? Will networking list be provided for the attendees from Industry Day?	Preferred yes, but not a mandatory requirement for all offerors in all circumstances, partnering is a foundational element of the 10 U.S.C. § 4022 authority and this specific acquisition strategy. Offerors should view the formation of diverse teams, especially those involving Non-Traditional Defense Contractors (NDCs) and small businesses, as a key strategic element for a successful proposal. A list of attendees will be provided.
	PPTS	What is the process of transporting the patient that is infected?	Utilize a PPTS that will be loaded into a vehicle then into a BCIS.
	PPTS	Would you desire the patient to be able to get out of the system?	We have not considered it. We would need to clarify with the services if that is a needed capability.
	PPTS	Does the DoW require the PPTS to support transport of mechanically ventilated patients while maintaining biocontainment?	Yes
	PPTS	Could the Government confirm whether this may be satisfied through a combination of hot-swappable battery packs that collectively sustain 12 hours of continuous operation, rather than a single battery configuration?	Yes that is the requirement.
	PPTS	Additionally, does the 1-minute maximum power interruption apply to each individual swap event?	Yes it applies to each swap event
	General	Could the Government confirm whether battery backup and a 200 lb package weight limit are threshold or objective requirements for the SIS, and if so, what is the minimum required battery backup duration?	Threshold - req 200 lbs for system. Battery backup duration - 60 minutes
	General	What is the preference for the solution? System or Components?	We are not integrating, we want a complete solution.
	General	Is this being procured via the CWMD OTA?	No, this is being procured via the Army Open Solicitation and will be a direct agreement with vendors, not a consortium.
	General	Under AOS what constitutes a “significant participant”?	The Government's definition of "significant participation" is intentionally qualitative, not quantitative. There is no specific dollar threshold or percentage of contract value that automatically qualifies as 'significant.' the Government will make a business judgment on a case-by-case basis. A contribution will be considered "significant" if it is material to the success of the prototype project. The focus is on the substance and importance of the NDC's contribution, not just its price.
	PPTS	Will the CFS allow for the production contract?	Yes, it will allow for follow-on production without a Justification and Approval for other than full and open competition.
	PPTS	The CFS states that Solution Briefs must assert to meeting or exceeding threshold requirements to be considered, but several requirements including FDA 510(k) clearance and full airworthiness certification are only required by the end of Phase III. Could the Government clarify whether the initial Solution Brief threshold assertion applies to current demonstrated capability, a credible plan to achieve requirements by the applicable phase, or both?
Specifically, is a Solution Brief acceptable if the offeror demonstrates a credible Phase III path to FDA clearance even if clearance has not yet been initiated?	The solution briefs for FDA 510 (k) clearance and full airworthiness are required by the end of Phase III. The Offerors RSP must demonstrate a credible approach to meeting the project's core objectives. Draft Interface Control Document (ICD); submission of the FDA 510(k) clearance request and performer's status with the FDA 510(k) clearance process.
	PPTS	Design a new system or current system with some deviations?	Up to the venter to submit which ever system that meets the timeline but also what the gov needs.
	PPTS	What are the quantities?	Up to 15 systems (Stated 3.2 of SOO).
	PPTS	What are the anticipated / projected quantity requirements for SIS in production quantities and over what period of time?	See section 2 (Follow-on production authority) of the Statement of Production
	PPTS	Could the Government clarify whether the initial Solution Brief threshold assertion applies to current demonstrated capability, a credible plan to achieve requirements by the applicable phase, or both?	The Government encourages solutions, even if they do not meet all requirements. Performers are permitted to iterate on their current designs to meet the requirements specified in Attachment 1, Tables 2 and 3, as long as the anticipated delivery timelines for Phase I can still be met.
	PPTS	Will the requirements mature as the program progresses?	Yes, there is a possibility that requirements may mature.
	PPTS	Can the DoW confirm whether user experience with Phase I prototypes may result in changes to the Desired Requirements?	It is not anticipated that the requirements will be changed.
	General	Timeline of phasing for ability to produce the extra prototypes?	No answer. We are stressed to meet the deadline schedule for testing.
	General	When will the final CFS be posted?	After the 01 April deadline and after all questions have been taken into consideration so that a final CFS/SOO can be established.
	General	When are questions due?	Varies. 1 April 2026 is the last deadline.
	General	When are submissions Due?	Mid-May at the latest.
	General	What are the differences between the dates identified in the Draft Call for Solutions (CFS) for the Questions due date and the date identified on Sam.gov?	All due dates for questions and proposed solution proposals will be identified in each final Call for Solutions.
	PPTS	What will be done with the questions submitted during Industry Day?	The questions will help ACC get their ducks in a row and will be provided to all vendors via Sam.gov.
	General	Would there be a requirement for Man Portability?	Man protability requirements should not exceed the existing man portability requirements for the existing TMT60 tent shelter
	PPTS	Weight? Per piece or system?	any one component must be no more than 50 lb, but total system must meet req of no more than 200 lbs in its stored configuration including storage containers.
	Common	Who are the Interested parties in PPTS?	USAF.
	PPTS	Does the system need to be soft or hard?	The additional evaluation criteria will guide which solution fits our needs.
	General	Is EMP and/or Ballistic paneling a requirement?	No requirement for ballistic.
	PPTS	Bio Protection/Govt testing?	May say in the SOO, we are not reiterating all the requirements in the brief, refer to the individual systems documentation.
	PPTS	Will the system undergo a road vehicle crash test?	Vehicle crash test is not anticipated.
	PPTS	MIL STD Testing? Do you require vendors to perform this?	Risk based assessment for vendor provided test results.
	PPTS	How often will they be used?	Hopefully never. Threshold requirement is for a single use system.
	PPTS	How many uses are required for SIS solutions?	There is no defined requirement for number of reuses, but is expected to last for the duration of its shelf-life. The vendor should provide an assertion of the number of uses they believe the system will sustain.
	PPTS	Could the Government clarify whether alternative waste management approaches, such as a sealed passthrough or red bag disposal interface, would be considered compliant with the spirit of the waste management requirement?	We will consider alternative options that are compliant with the spirit of the waste management requirement.
	PPTS	Additionally, is the 5-liter per receptacle volume a firm desired requirement or is there flexibility based on the enclosure's overall footprint?	Alternative options would be considered, but must still meet the 10 liter waste containment requirement.
