Join the A/E Reference File Consultant Pool

The Architecture/Engineer (A/E) Reference File (Utilized by University of Washington, Department of Enterprise Services & many other Washington State public owners) is a central file of consultants’ Architect-Engineer Qualifications (Form 330) and web addresses.

Washington State government organizations use the file to select consultants based on qualifications instead of a bidding process for public works projects with an estimated fee under $500,000.

Join the On-Call Consultant List

On-Call Selections are intended to provide service throughout Washington State on as-needed basis. While On-Call consultant services are limited to $300,000 maximum fees per project, there is no limit to the number of projects a selected firm may perform per biennium.

Every two years, E&AS publishes a Request for Qualifications for consultants for a variety of discipline areas. Consultants must be able to provide complete services for the specific discipline selected for, including but not limited to studies, design, bidding, contract administration and project close-out.

Once qualifications received, they are reviewed by a consultant selection board consisting of E&AS project managers based upon published criteria. The consultant selection board recommends top candidates for each discipline area. Once interviewed, the consultant selection board selects top qualified firms for each discipline area and those firms are put on an On-Call list that E&AS and its’ clients use for projects throughout the biennium.
