Procurement Services

Welcome to the Office of Procurement Services. Transparent, fair and competitive public procurement across the County generates business opportunities, drives economic growth and creates jobs. By rethinking the entire approach to purchasing, professionalizing public buyers, cutting red-tape, and capitalizing on the benefits of the digital revolution, procurement  can be made more efficient, more effective, and more citizen and business-friendly. Improved governance, the simplification of procedures and the greater use of electronic tools in public procurement are also important tools for fighting fraud and corruption.
