Notices are published on the Office of Procurement Services' website when the County issues formal competitive solicitations (RFPs, IFBs and RFQs) for those procurements expected to exceed $50,000. The notices are accompanied by the entire solicitation document, when practical, in a downloadable format. Notices are also posted in the Office of Procurement Services offices and published in county’s newspaper or record which is currently the Arizona Business Gazette. When a wider distribution is deemed necessary for any type of solicitation, regional and national publications may be used to circulate the required information.
