I have done a great number of these proposals, both for The City and County of San Francisco, and for private clients. I've managed up to 14 sub-consultants on a team where we were the Prime Consultant, coordinating with marketing personnel and leadership at other firms to present one cohesive proposal to the final client. Submitting these to The City means compliance forms are crucial and anything that strays from the very specific instructions in the RFP can mean disqualification.
