The budget for this opportunity is difficult to estimate due to the lack of specific information in the document. However, considering the scope of the project, which includes the development and implementation of a comprehensive Airport Security Record Keeping and Auditing System, the budget could be substantial. The system must be secure, centralized, and auditable, and must support security operations by maintaining accurate records for personnel, credentials, access control activities, inspections, incidents, investigations, training, equipment maintenance, regulatory compliance activities, and corrective actions. The solution must provide comprehensive audit capabilities, enforce role-based access control, and protect Sensitive Security Information. Factors that may influence the likely payment range include the complexity of the system, the number of users, the level of customization required, and the level of support and maintenance needed. Based on these factors, a rough estimate for the budget could be between $500,000 and $2,000,000.
