I have always believed that the government may allow a contractor to write the SOW or requirements for the government. The government can use these specifications in their solicitation, but the contractor cannot bid on the resulting contract from those specifications that they supplied because it would be a conflict of interest. I have searched through the FAR and cannot find any specific FAR language that absolutely prohibits the practice. This would be a unique service where there is a limited number of contractors available to complete the work with different methods of completing the contract. Any thoughts. Thanks. This is still in pre-solicitation but will be a time sensitive procurement due to a very narrow weather window.
