1. INTRODUCTION AND PURPOSE

The Department of the Army is conducting market research in accordance with Federal Acquisition Regulation (FAR) Part 10 to identify sources capable of developing a Frequency Inverter-Converter based on the furnished Government drawing, 98-19604. Note: reference attached drawings (98-19521, 98-19524, 98-19525, 98-19780, 98-19781, and 98-19782), appendices, and Purchase Description for additional information. The Government owns the competitive Technical Data Package (TDP) for this integration. The TDP will not be provided during the RFI phase. The TDP will be provided as Government Furnished Information (GFI) under subsequent competitive actions. Vendors must base their responses and rough estimates solely on the drawings and appendices attached to the RFI.

This RFI is solely for information and planning purposes and does not commit the Government to contract for any supply or service. The Government is not at this time seeking proposals and will not accept unsolicited proposals. Telephone inquiries will not be accepted or acknowledged, and no feedback or evaluation will be provided. The Government will retain all responses, which will be protected as business sensitive and will not be released outside of the Government and the Government’s program support contractor(s). The information provided may be used by the Government in developing its Acquisition Strategy, Performance Based Specifications, and/or related Acquisition Requirement documentation. Respondents are advised that the Government will not pay for any information provided, or administrative costs incurred, in response to this RFI; all costs associated with responding to this RFI will be solely at the Respondent’s expense.

Defense and commercial contractors, including small businesses, veteran-owned businesses, service-disabled veteran-owned businesses, HUB Zone small businesses, and woman-owned small businesses are encouraged to participate. Not responding to this RFI does not preclude participation in any future Request for Proposal(s) (RFP), if any is issued.

It is the responsibility of the potential offerors to monitor additional information pertaining to any future requirement.

• Performance Requirement: The final integrated system must be capable of meeting standard military requirements for environmental durability (e.g., resistance to rain, dust, vibration, humidity, etc.) and endurance/reliability.

3.7.1 Component & System Details (Government Furnished Equipment - GFE)

The following GFE will be provided for development and shall be taken into consideration when developing the ROM:

• Generator: 3 kW Tactical Quiet Generator, 60 Hz (MEP-831A), with approximate dimensions of 34.8"L x 27.8"W x 26.5" H and a dry weight of 304 lb.

• Detailed information is available in appendices and the 3 kW TQG purchase description, accompanying this solicitation.

3.7.2 Cost Estimate Instruction

ROM cost estimate for a frequency inverter-converter shall be IAW the specifications identified in Government drawing, 98-19604 (reference attached drawings (98-19521, 98- 19524, 98-19525, 98-19780, 98-19781, and 98-19782), appendices, and the 3 kW TQG PD for additional clarifying information). These estimates should be broken-down as follows:

• Non-Recurring Engineering (NRE) Cost (as a delineated cost from total cost, break down as desired for additional information).

• Production cost for initial 10 prototypes.

• Developmental Test Cost: Refer to appendices for list of tests.

• Include a brief Basis of Estimate (BOE) explaining the methodology and assumptions used to derive your figures (e.g., estimated labor hours, material types).

• Per-Unit Production Cost (assuming 150 systems per year). Note: This per-unit production cost is not mandatory for the ROM; however, providing this recurring cost provides for planning purposes.

3.7.2.1 Assumptions:

• All GFE (generator(s)) will be delivered to the vendor's facility.

• The vendor is responsible for all non-recurring engineering (NRE) associated with designing, developing, producing, and testing of the frequency inverter-converter.
