Attachment_E_NIEHS_Level_of_Effort_worksheet.xlsx

This is a Level of Effort cost proposal template for the NIEHS Division of Translational Toxicology Chemistry Research contract (Solicitation 75N94026R00002). Offerors must utilize the provided Excel template to submit detailed cost proposals with all calculations flowing from labor rates and hours entered into designated yellow cells. The template requires input of hourly rates for four labor categories: Senior Research Professional (GS-14/15), Research Professional (GS-12/13), Technical Staff (GS-7/11), and Support Staff (GS-5), along with indirect cost rates (fringe benefits, indirect costs, G&A, and fixed fee). Offerors must also apply a 3% annual inflation escalation factor across the contract period.

The cost structure addresses two distinct work scopes: base services and optional studies (Option 1). For each, offerors allocate labor hours across 22 defined task types including ADMES, AWA, BMD, BSA, CCA, CH, CIPS, CP, CRA, CS, FA, FD, FPAS, IVS, MCH, MCP, MIPS, PD, PFS, SCA, SHIP, TKS, VA, and OMICS, plus contract administration. The base year costs flow through to ten option years, with Option Year 10 representing a six-month extension under Option 2. The template includes separate worksheets for base labor and cost details, optional work labor and cost details, direct labor calculations, other direct costs (materials, supplies, equipment, travel, consultants, computing), indirect costs, and cumulative contract totals. Any modifications to formulas must be noted for evaluator identification.
