Attachment 0004_Cost Proposal Template .xlsx

This is a Cost Proposal Template for software engineering services supporting Command and Control Experimentation (C2X) and Modernization for Future Naval Operations under Solicitation N66001-26-R-3608. The template is designed for SEAPORT-NxG IDIQ contract holders and establishes the cost proposal structure for a base year plus four option years (CLIN 0001-0004 for labor; CLIN 0002-0004 for Other Direct Costs).

The template requires offerors to submit detailed labor cost breakdowns using fully burdened rates for prime contractor personnel and unburdened direct labor rates for subcontractors, with separate submissions from subcontractors sent directly to the government. Cost elements include direct labor organized by eCraft labor categories at government and contractor work sites, indirect costs (fringe benefits, overhead, and G&A calculated as percentages), Cost of Money, and Other Direct Costs. The template mandates maximum pass-through costs of 8% and maximum fixed fee of 8% per SeaPort-NxG guidance. Offerors must provide escalation rates for each contract period, fully burdened rate sheets for each year, and indirect rate supporting documentation with three years of actual overhead expense data and allocation bases. Prime contractors must ensure coordination with subcontractors to verify that hours, labor categories, and total costs match exactly between subcontractor proposals submitted to the government and those reflected in the prime's proposal submission.
