These items are required to maintain compatibility with the existing AMI network, support data collection, analysis, reporting, and network protection, and align with specific Unified Facilities Guide Specification sections for metering.

• The estimated value for this J&A is $1,800,000.

• This justification covers only the specified brand-name items; other aspects of the AMI program will be acquired competitively.

• The proposed action will be synopsized on the Government-wide Point of Entry as sole brand availability.

• The Government will accept only prices determined to be fair and reasonable.

• This is a justification for other than full and open competition, citing 10 U.S.C. 2304(c)(1) and FAR 6.302-1(c) due to the requirement for a single responsible source.

• The use of different metering and wireless devices would result in significant duplication of costs, endanger the existing AMI system's warranty, and violate the Platform Risk Assessment (PRA) accreditation.

• No additional market research was conducted as it was deemed not practicable.

• NAVFAC EURAFSWA has no current plans to compete future contracts for these specific items, but will assess feasibility if other potential sources emerge.
