## Description

This J&A leverages the authority of FAR 6.302-3; “Industrial mobilization; engineering, developmental, or research capability; or expert services”. Consistent with the requirements of FAR 6.305, this J&A is being made publicly available. All costs associated with responding to this justification will be solely at the interested party’s expense and any information provided in response to this justification is purely voluntary. Not responding to this justification does not preclude participation in any future competition or participation in future subcontract opportunities which may arise with NSF.
