Construction Management
Construction Management reviews and provides design recommendation to Capital Projects prior to advertisement of a bid, takes responsibility for management of the construction process from bid opening through project completion, evaluates any claims submitted by Contractors, performs all field quality control, prepares inspection reports, and handles all warranty work notification and verification. Construction Management also provides these same services to other Sonoma County agencies, assisting County Departments that don’t regularly contract projects. Towards the end of this page is the lists of projects in-progress or projects that have been completed in the past two years.
