Capital Projects Team: Building for the Future

Our Capital Projects Team oversees a wide range of projects—planning, coordinating, and managing each step from concept to completion. The Team works closely with County departments, agencies, and outside experts to deliver projects that meet community needs, stay on schedule, and make the best use of public funds.
Bid Opportunities & Permits: To bid on a project, please visit the Supplier Portal, which lists all the County’s bidding opportunities. If you’re looking for permits or inspections, please visit Permits and Resource Management.
