(a) Any document posted to the Electronic Data Access (EDA) system is part of the contract file and is accessible by multiple parties, including the contractor. Do not include in EDA contract documents that are classified, too sensitive for widespread distribution (e.g., personally identifiable information and Privacy Act and Health Insurance Portability and Accountability Act), or attachments that cannot be practicably converted to electronic format (e.g., samples, drawings, and models). Inclusion of any document in EDA other than contracts, modifications, and orders is optional.
