Looking for info on allowable costs. The contract will have FFP CLIN and CPFF CLINS for labor. The FFP CLIN will be priced for a mix of labor categories with an estimated number of employees in each. The CPFF CLINS will be O&A work as needed not included in the FFP CLIN. So trying to understand allowable cost for the O&A CLIN, if an employee under the FFP works on O&A work during his normal 40 hours paid time, is this O&A work an allowable cost for the CPFF CLIN.
