The RFQ method is used primarily for establishing capacity contracts through a qualification-based selection of professional A-E services when future services are necessary from numerous firms for an undefined project scope of services as required by A-Es of the same or similar discipline. A RFQ will be advertised and firms will submit a Statement of Qualifications (SOQ).

Establishment of the Qualified Vendor List and On-Call Contracts

The firm is required to submit a Statement of Qualifications  (SOQ) in response to a Request for Qualifications (RFQ). A minimum score is established as a pass point for respondents to qualify for inclusion in the QVL. An evaluation panel scores the respondents SOQs with all responsive SOQs meeting the minimum pass point will be included in the QVL. The highest scored respondents may, at the discretion of the evaluation panel and based on the County needs, be invited for interviews for determining which firms will be recommended for on-call contracts with specific dollar amounts. The Director may use the QVL for various services as required. The QVL is typically solicited at least once every three to five years to give additional firms an opportunity to participate.

The QVL may also be utilized as the first step of the two-step process defined as a Request for Proposal. An invitation to submit proposals on a specific scope of work can be sent to all vendors within the QVL and the proposals will be evaluated based on the established criteria set forth in the invitation.

The QVL may also be utilized as the first step of the two-step process defined in Section 3.3-105(3) od the Design and Construction Policy Manual (DCPM). An invitation to submit proposals on a specific scope of work can be sent to all vendors within the QVL and the proposals will be evaluated based on the established criteria set forth in the invitation to submit a technical proposal and may be required to submit a price proposal. Proposals by all firms are evaluated by an evaluation panel based on criteria outlined in the RFP. The evaluation panel scores the proposals at which point final price negotiations may begin with the firm having the highest evaluation rating. The contract may be awarded to one firm for project specific services or for repetitive services that may be required over the term of the contract. The selection and award of these contracts will require approval by the Board of Supervisors when exceeding the DCPM Section 3.3-102 thresholds.
