Wattmeter Calibration Systems

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the Wattmeter Calibration Systems solicitation (N6426726R1003), clarifying various aspects of the requirements and schedule.

• Delivery Schedule: The "date of lead time event" for the first Delivery Order (DO) begins upon issuance of the DO. Amendment 0002 is forthcoming to revise delivery dates, specifically addressing a potential 12-month lead time for the initial system while subsequent systems maintain a 90-day interval.
• CMMC Requirements: Offerors must adhere to DFARS 252.204-7025 and 252.204-7021. Level 1 (Self) CMMC status must be recorded in SPRS prior to award. The required CMMC level is Level 1 (Self) throughout contract performance unless modified by a specific DO.
• Transfer Standards: Automated or electronically switchable paths for RF transfer standards are not explicitly required. Manual operator-performed connections are acceptable, provided accuracy requirements are met and transfer standards are modular/removable.
• Demonstration Unit: No demonstration unit or formal demonstration event is required upon award or prior to acceptance of the first system.
• Turnkey Solution: The Government intends to award a single prime contract for a complete, integrated turnkey solution (PLWCS and WCS). Component-only proposals are considered non-responsive/technically unacceptable.
• Alternative Proposals: While FAR 52.212-1(e) permits multiple offers, any alternative proposal must still conform to the solicitation's requirements for a fully integrated turnkey solution.

Amendment 0002 is forthcoming, which will revise delivery dates. Bidders should note the clarification that a turnkey solution is required, and component-only proposals will be deemed non-responsive. CMMC requirements are confirmed as per DFARS clauses.
