Sheet1
| Question | Government Response |
| Is the Excel File; Copy of Price Schedule (Attachment 2).xlsx, protected? | Yes, this has been replaced by Copy of Price Schedule Attachment (rvs).xlsx, and should be accessible. |
| Are the previous part numbers or NSNs available or is that information part of the material in the Controlled Technical Documents? | NSN: 6665-01-565-7438 |
| Access to Controlled Technical Documents: Is CMMC Level 1 sufficient instead of CMMC Level 2? | Yes, we have adjusted the requirement for this solicitation to CMMC Level 1 (Self) reflected in the Supplier Performance Risk System (SPRS) for each contractor information system. The link for FAQ for NIST and CMMC is provided here (paste in browser); https://search.certifications.sba.gov/advanced?page=0 |
| Will the deadlines for document requests and questions be extended? | Yes, please see the revised Synopsis and Solicitation attachment for details. |
| The steady‑state input power limit of <1,400 W conflicts with the required steady‑state output power of 1,100 W AC plus 250 W DC at the specified minimum efficiency in the PSPEC. | This has been addressed in a revised verson of EA-E-2450, PSPEC for the Shipboard Power Pack (SPP) |
| The objective requirement to recharge a completely depleted battery in <60 minutes is incompatible with reasonable charging C‑rates for sealed lead‑acid (SLA) batteries at the battery capacities implied by the backup runtime requirement. | This has been addressed in a revised verson of EA-E-2450, PSPEC for the Shipboard Power Pack (SPP) |
| What is the intended timeline for Contractor-performed First Article Testing (FAT)? |
The PWS indicates Contractor testing, but also delivery of articles for government testing (PWS 3.2.3) and Compatibility Testing (3.2.3.1).
| Is the intent that the Contractor "delivers" First Articles for internal testing at 90 calendar days (PWS 4.1 Test Units), then performs its portion of the FAT, before shipping the units to the government; or that the Contractor First Article testing be performed on separate units? | All Contractor conducted First Article Testing (FAT) will be performed on the three (3) units specified in PWS 4.1 prior to the delivery of the three (3) test units to the Government (no later than 150 days after contract award). | |
| The Inspection Requirements numbering in EA-E-2450 do not line up with the numbering/labels of tests in the PWS 3.2.3, Government Conducted Testing. For example, Shock Requirements are listed as 4.5.4.2.3 (presumably .1 and .2), but as 4.5.2.5.2.3 in the PWS. Please confirm which tests the government plans to conduct themselves. | Please see the revised PWS for the revised paragraph references. | |
| EA-E-2450 3.1.6.5 indicates a lithium battery -- are other types of batteries acceptable? | Yes, other battery types are acceptable. The Government will not provide Government sponsorship for NAVSEA S9310-AQ-SAF-010 approval of lithium batteries for this procurement. If lithium batteries are proposed vendors should have NAVSEA-approved lithium battery designs that comply with S9310-AQ-SAF-010. | |
| PSPEC EA‑E‑2450 Rev 1, 3.1.6.4. Section 3.1.6.4 requires the battery charger to be capable of charging a completely depleted battery in less than 12 hours, but the PSPEC does not define the starting or ending battery state. How should “completely depleted” and “charged” be defined for purposes of demonstrating compliance with the 12‑hour recharge requirement (e.g., depth‑of‑discharge, terminal voltage, or state‑of‑charge limits)? | “Completely Depleted” is the state where the power pack’s "Battery Low" Built-In-Test (BIT) signal is triggered per Section 3.1.9.5 (when it has been discharged to the point that the power pack's Built-In-Test (BIT) indicates the battery is no longer able to perform its backup function). |
“Charged” is the state where the battery can successfully meet the threshold backup power requirement of the minimum threshold per Section 3.1.6.3 (when the charging function has completed and the battery is capable of meeting the minimum (threshold) backup power requirement).
| PSPEC EA‑E‑2450 Rev 1, 3.1.12.1 / 3.1.12.1.1. The PSPEC specifies an alphanumeric status display with two lines for text and requires the first text line to display voltage and current values for the AC and DC outputs, but does not define display flexibility or formatting. Is a status display with more than two lines acceptable, provided all required information is displayed and human‑factors requirements are met, and should AC and DC currents be displayed separately, or is a combined/aggregated current display acceptable? | Yes, a status display with more than two lines is acceptable. The PSPEC requires AC and DC currents be displayed separately. |
| PSPEC EA‑E‑2450 Rev 1. 3.5.3. The PSPEC defines controlled and uncontrolled storage requirements but does not explicitly state whether these requirements apply to the battery pack, nor whether battery maintenance is permitted during storage. Do the storage requirements in Section 3.5.3 apply to the battery pack as well as the power pack enclosure, and is battery maintenance or conditioning permitted during storage periods? | The storage requirements in Section 3.5.3 apply to both the battery pack and the power pack enclosure. Yes, battery maintenance or conditioning is permitted during controlled storage. |
| PSPEC EA‑E‑2450 Rev 1, CDRLs / DIDs. For a total fixed‑price procurement of 40 Shipboard Power Pack units, ROM estimates indicate that documentation and data deliverables represent a significant portion of the per‑unit cost. Is the Government open to tailoring CDRLs and associated DIDs (scope, format, frequency, or level of detail) to reduce per‑unit cost for a 40‑unit total fixed‑price purchase, while still meeting program and sustainment needs? | To clarify, the Government is buying up to 23 units under this effort. We do not plan to tailor the DIDs at this stage of competition. We may consider working with the awardee on specific CDRLs after award. |
| PSPEC EA‑E‑2450 Rev 1, Section 4. The PSPEC includes extensive First Article and conformance testing requirements that may require specialized facilities and test setups. Will required verification and testing be funded separately by the Government, or should offerors assume all testing costs must be included in the proposed unit price? | No, the First Article Testing and required verification testing will not be funded separately. Please see the price schedule attachment and corresponding paragraph reference of the PWS for the proper allocation of funds. |
| PSPEC EA‑E‑2450 Rev 1, 3.1.6.5. Lithium batteries require approval in accordance with NAVSEA S9310‑AQ‑SAF‑010, which requires a Government sponsor. Will the EMBD program provide Government sponsorship for NAVSEA S9310‑AQ‑SAF‑010 approval of lithium batteries, or should offerors assume lithium battery solutions are out of scope for this procurement? | The Government will not provide Government sponsorship for NAVSEA S9310-AQ-SAF-010 approval of lithium batteries for this procurement. If lithium batteries are proposed vendors should have NAVSEA-approved lithium battery designs that comply with S9310-AQ-SAF-010. |
| PSPEC EA‑E‑2450 Rev 1, Table II / 3.1.2.3. Table II identifies a single +24 VDC output pin and return pin supporting the 250 W DC output, corresponding to approximately 10.4 A continuous current. Can the Government confirm whether 16 AWG wiring is the expected minimum conductor size for the DC output harness, or whether alternative wire gauges are acceptable provided the DC output current, temperature rise, and environmental requirements are met? | Wire gauge should be in accordance with the specified connector in Table II, the specified contact size and the current bearing capacity of those contacts. |
| The PWS states that 10 units shall be delivered No Later Than 90 Days after award. Is that 90 days a hard deadline or could an alternate delivery schedule be proposed? | The requirement to deliver test units has been extended from 90 days to 150 days after the contract award. Please see revised PWS. Participants are welcome to propose different delivery schedules for test units and production units as long as the schedule does not exceed 12 months after award (proposal schedules will be evaluated as unacceptable/meet/exceed). |
| Are we able to share the controlled documents with prospective partners, assuming we follow all the necessary cyber security measures? | Prime contractors are responsible for ensuring their subcontractors also adhere to these access limitations and data handling requirements when sharing of data is required. |
