Doing Business with Historic Seattle

Historic Seattle maintains properties within its portfolio and engages in development projects throughout Seattle. In accordance with current and applicable sections of the Revised Code of Washington (RCW) Title 39, Public Contracts and Indebtedness, Historic Seattle often relies upon the services provided by contractors, consultants, and vendors. Transparent Project Roster, Request for Qualification, and Request for Proposal processes are utilized to obtain professional assistance.

Project Roster

Historic Seattle Preservation and Development Authority (PDA) maintains a Project Roster, per RCW Title 39, Public Contracts and Indebtedness, to assist in the selection of contractors, design-builders, vendors, and consultants for all work under $350,000 in estimated value, defined by the State of Washington as Limited Public Works Projects. Historic Seattle PDA selects eligible firms to participate in the proposal/bidding process on a per-project basis.

All firms who potentially or currently work with Historic Seattle PDA must be registered with MRSC Rosters, the service that hosts and manages our Project Roster.
