Solicitation / RFP / RFQ

This document is a Brand-Name Justification and Approval (J&A) for a Firm-Fixed-Price purchase order. It details the procurement of SIEMENS industrial control hardware and associated equipment for a technology refresh of the Machinery Control System (MCS) Land-Based Test Environment (LBTE) at the Naval Surface Warfare Center, Philadelphia Division (NSWCPD). This refresh is necessary to support hardware modernization efforts for the Class Engineering Control System (ECS).

• SIEMENS ET200-SP series Programmable Logic Controllers (PLCs)
• SIEMENS IE/PB Link Protocol Conversion Gateways
• Supporting hardwired modules for the ET200-SP PLC

Specific part numbers, descriptions, and quantities are listed, including:

• ET200SP CPU 1510SP-1 PN (Qty: 130)

• Digital input module NAMUR, 8 channel (Qty: 170)

• Digital output module, 8 channel (Qty: 60)

• Relay output module, 2 channel (Qty: 20)

• Analog input modules (voltage, current, RTD) (Quantities: 30, 480, 25)

• Analog output module, current, 2 channel (Qty: 10)

• Serial module, RS422/485 (Qty: 5)

• Base module for ET200SP (Qty: 80)

• Contract Type: Firm-Fixed-Price purchase order.

• Funding: FY26 Other Procurement, Navy funding.

• Delivery: Requested delivery is twenty-four (24) weeks from the date of award.

• Options: No option quantities or periods.

This document is a justification for other than full and open competition, citing 41 U.S.C. 1901. The rationale emphasizes that Siemens is the only responsible source due to unique characteristics essential to the Government's requirements. Market research, including a Sources Sought Notice, did not yield responses from other vendors. The procurement is brand-name specific to ensure compatibility with existing ECS software and hardware configurations.

This procurement is being conducted on a brand-name basis, limiting competition to authorized Siemens distributors. Market research identified a minimum of four viable sources for procurement of Siemens components.

This procurement completes the modernization effort for the MCS LBTE at NSWCPD. Future contracts for similar supplies/services are not planned to be competed by NSWCPD.
