CONSULTANT SELECTION PROCESS

Enclosed is a copy of the City of Antioch’s Consulting Services Agreement. By submitting a

proposal for this work, a firm agrees to comply with all terms and conditions outlined in the

agreement. The City anticipates awarding a contract for an initial three-year term, with the option to

extend it for two additional years at the City’s discretion.

It is anticipated that from the qualifications submitted, City staff will be able to select the firm best

suited to meet the City’s needs. However, if that is not possible, the City will ask a “short list” of

professional services contract for the work after staff have determined the best qualified firm.

No compensation will be due any firm for preparation of a written proposal or for meeting with staff

after a “short list” has been determined.

The selected firm will receive a notice to proceed after the City Council has approved their contract.
