Our current system (Online Vendor Registration) will be retired in Fall 2020!

Until the new system launches, we'll continue using our current system to manage our Rosters. For more information regarding the new system, click here.

Architectural/Engineering Consultant Roster

The Consultant roster may be used to award contracts for capital projects with an estimated cost of less than $500,000.

Projects solicited via the Consultant Roster are not advertised. King County will invite at least one SCS-certified small business to submit a proposal for every project, if available in the solicited category. 

There's no limit on how much work can be awarded to SCS-certified small businesses through the Consultant Roster. Larger firms can be awarded up to $500,000 annually, per agency.
