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 (NAICS code). 

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.

Applying to the roster is part of the registration process in the E-Procurement Supplier Portal. If you do not sign up for the Consultant Roster as part of your initial registration, you must email procurement.web@kingcounty.gov to receive an invitation to the roster.
