| Question and Answer Document 3: EESSS Draft RFP FA8534-22-R-0002 | |
| The government’s specification shall take precedence/priority over any questions/answers response in the event there is a conflict between the former and latter. | |
| 3.2 Energy Efficient Small Shelter description. | Comments |
| The EESSS is intended to be a lightweight, energy efficient expeditionary shelter system, to be used by the United States Air Force (USAF) for the purposes of billeting, storage, and work space. The EESSS shall be a fabric structure, measuring approximately 20.0 feet in width, by 32.0 feet in length, configurable to allow multiple shelters to be connected and shall meet all requirements specified henceforth. | Yes the vestibule is considered an integral component of the shelter and will be included in all testing. |
| The vestibule is not mentioned in 3.2 Energy Efficient Small Shelter System description, is the vestibule to be included in requirements 3.4 Deployment and recovery time and/or 3.5 Environmental conditions? | |
| 3.3.2 Interior peak height. | |
| The minimal interior (liner) peak height shall be no less than 8.0 feet measured along the centerline of the shelter. | Yes. The headroom is measured in an operating set-up to include any additional components. |
| Does this minimal interior (liner) peak height include the plenum and other systems requirements/accessories to ensure 8.0 feet of headroom? | |
| 3.3.4 Shelter system sidewalls. | |
| The shelter shall have sidewalls that are a minimum 7.0 feet high. The sidewalls shall not slope more than a maximum of 16.0 inches from the base to the top of the sidewall. | The geometry will be calculated such that a minimum of 7 ft headroom measured 16 in. perpendicular from the side wall base. |
| The Air Force has used a Quonset shaped shelter for over 20 years. A Quonset shaped shelter has a slope of significantly more than 16.0 inches (more than double) from the base to a height of 7.0 feet. Is the intention of the Government to disqualify a Quonset shaped shelter from meeting this EESSS requirement? | |
| 3.3.5 System weight: | |
| States - “The EESSS system weight shall encompass the shelter along with all supplied components, including, but not limited to: fabric skin, support structure, interior insulating liner, solar shade fly, electrical system, lighting, flooring, plenums, vestibule, wind lines, anchoring system, repair kit, manual, supplied tools (such as lift poles, etc.) and any other additional gear needed to complete the shelter system. | |
| If a ladder, compressor, or power generation is required to complete the shelter system is that weight to be included in the EESSS systems weight? | No. The support equipment is not included as system weight. |
| Additionally, if these are required to complete the shelter are they to be provided by the offeror? | Support equipments will be covered as part of the MRSP. |
| Based on known commercial solutions, an 1,100 pound system weight with insulated liner and vestibule is challenging. Is this a threshold maximum weight of the system or an objective weight? Would the Government consider providing a threshold and objective system weight for offerors? | The maximum accpetable weight of the entire shelter system is 1100lb. |
| 3.3.6 Modular design. | |
| The EESSS shall be designed to allow personnel in the field to connect multiple shelters in an end-to-end configuration. | Yes. The entire end wall must be removed to allow the total cross section area to be shared from with each additional shelter added. |
| For clarification, when connecting multiple shelters in an end-to-end configuration as shown in FIGURE 1 on page 24, is it required that the endwall be removed (no center wall). A connection just the doorway does not meet this requirement. | |
| 3.5 Environmental conditions. | The Government expects the manufacture to perform/provide all testing specified. |
| Is it the Government’s intention that the offeror will supply third-party test reports with respect to Section 3.5 Environmental conditions with its proposal? | |
| 3.6.1 EESSS fabric skin. | |
| States “The EESSS’s fabric skin shall be Class 1 Tan 686A, in accordance with USISI-PRF-44103.” | |
| There is no mention of blackout in the purchase description. However, blackout is a requirement to meet USIFI-PRF-44103 fabric specifications. Can the Government confirm that the blackout requirement is waived? | No blackout is required. |
| 3.6.3 Shelter frame: | |
| “If the EESSS shelter frame requires a separate exoskeleton frame to support the weight of the PV system, the PV supports shall be the same color as the shelter and shall not be considered part of the EESSS.” | |
| This states that regardless of the increased weight and size of additional frame to support the weight of the PV systems it is not considered part of the EESSS. | If an additional frame is required to support 600lbs, it will be considered part of the EESSS. |
| Can the Government confirm that this allows another frame potentially the same weight and size of the shelter frame to be used to support the PV system and gives no advantage to a shelter system that requires no separate exoskeleton frame. | Confirmed. The EESSS must accomdate 600lbs, either with existing shelter frame or an additional exoskeleton. |
| Since Factor I includes Transportability as an evaluation criterion and it is an Energy Efficient Shelter, shouldn’t the PV support be considered part of the EESSS? | If an additional frame is required to support 600lbs, it will considered part of the EESSS. |
| 3.6.4.1 Solar shade fly: | No solar fly is required for end walls. |
| Is a solar shade fly required to include an endwall solar shade fly (with door openings) or just the roof and side walls? | |
| 3.6.4.1 Solar shade fly: | |
| In the Questions & Answers from 2020: | |
| Q: Is it acceptable to the USAF to put the PV system (fly) directly on the shelter cover and frame without an exoskeleton frame? | |
| A: “The structural integrity of the frame must be capable of supporting the 600lb weight of a fly (with or without PV integrated). A functional solar shade fly design must allow adequate air space between exterior shelter fabric and solar barrier material. “ | |
| Shouldn’t this statement be included in the current Purchase Description to ensure a functional solar shade fly and that when integrated with Photovoltaics that potential heat generated doesn’t adversely affect the EESSS? | The design of the shelter must meet all environment testing with the use of a solar fly if the solar fly is an integral component of the shelter. |
| 3.6.5.3 Vestibule: | No solar fly is required for vestibule. No lighting is required in vestibule. Yes. The vestibule is considered an integral component of the shelter system for all testing. |
| Is a solar shade fly required to cover the vestibule? Is the vestibule required to have lighting? Is the vestibule required to meet section 3.5 Environmental conditions? | |
| 3.6.7 Heating ventilation and HVAC duct adapters. | No Y's, adapters, or ducts are required. REVISED |
| States that “Ys” and adapters shall include insulated wraps for system. Can you specify a minimum energy efficiency R-value and should this insulated wrap be included in the EESSS 3.3.5 System weight? | |
| 3.6.8 Internal plenums | Yes. The Government would like the designer to consider the available interior headroom when planning for air distribution. |
| The EESSS plenum shall impose the least impedance possible on the shelter’s usable interior space. | |
| Can the Government please better define “impose the least impedance possible”? Does the Government mean that the plenum shall maintain the interior peak height of a minimum of 8.0 feet along the centerline and 7.0 on the sidewall? | |
| 3.6.11 Interior Lighting. | Yes. Consideration would be given to an illuminated switch. |
| Would the Government consider an illuminated switch other than a rocker switch? | |
| 3.6.4 Energy efficiency. and 4.6.6.3.1 Energy efficiency tests. | |
| Just for clarification, each offeror is to identify a climatically controlled chamber large enough to connect two 600 sq ft EESSS shelters side-by-side and end-to-end with capability to provide +116 ˚F with 1120 W/m2 of solar radiation in a diurnal cycle (MIL-STD-810 Method 505.7, Procedure I and Table I of MIL- HDBK-310 hour 13) and also provide an ambient environment of -25 ˚F to +125 ˚F. | |
| Is this climatically controlled chamber testing completed as part of the verification process by the Government, or is it to be scheduled, performed, and paid for by the offeror? | The entire testing process for the EESSS is a verification. All testing will be the responsibility of the offeror. |
| 4.2 First article inspection: | Same as previous answer. |
| “The contractor shall provide or arrange for all test equipment and facilities.” | |
| Can the Government confirm that “provide or arrange” includes all scheduling, execution, and cost of testing listed in Section 4: VERIFICATION? | |
| 4.6.4 Deployment and recovery time verifications. | The Government will provide pratical MOPP gear for testing purposes. |
| Will the government provide all individual protective equipment listed (e.g., helmet, individual body armor, arctic mittens) to conduct these verification activities? | |
| The government’s specification shall take precedence/priority over any questions/answers response in the event there is a conflict between the former and latter. |
