Attachment 0004_Cost Proposal Template.xlsx

This is a Cost Proposal Template for a Command and Control Experimentation (C2X) and Modernization Software Engineering Services contract (Solicitation N66001-26-R-3608) under the SeaPort-NxG IDIQ contract vehicle. The template is designed for use by prime contractors and subcontractors to submit fully burdened labor rates and other direct costs (ODC) across a base year plus four option years.

The cost proposal structure includes detailed labor cost breakdowns organized by Contract Line Item Numbers (CLINs) for both government and contractor work sites, with separate sections for direct labor, indirect costs (fringe benefits, overhead, G&A), and Cost of Money calculations. Prime contractors must submit fully burdened rates using subcontractor costs, while subcontractors submit unburdened direct labor rates directly to the government, with strict requirements that hours and costs match exactly between prime and subcontractor submissions. The template incorporates fee analysis with a maximum fixed fee allowable under SeaPort-NxG of 8 percent and includes pass-through cost analysis limitations. Additional required submissions include fully burdened rate sheets for each contract period (base year and four option years) and indirect rate detail documentation with supporting overhead expense data and allocation bases. The template emphasizes coordination between prime and subcontractors to ensure consistency in labor categories (eCraft codes), hours by work location, and total contract pricing across all proposed periods.
