This is a market research notice seeking commercially available cost estimating databases or applications for potential use in Job Order Contracts within the NAVFAC Southeast Area of Responsibility. The required system must be a web-based platform with an annually updated cost database using the CSI work breakdown structure and an application capable of creating custom reports, templates, and future cost adjustments. A key requirement is that the system must be approved by the NAVFAC Command Information Officer and certified for the Navy-Marine Corps Intranet (NMCI) network. The Government indicates that RSMeans Online is a currently known and approved source that meets these requirements. If no sufficiently advantageous alternate sources are identified by the specified response deadline, a competitive procurement will be issued specifying RSMeans as the brand name.
