Ozanne provides single source responsibility for design, engineering, construction and close out in partnership with architects and engineers using the design build delivery system. The owner contracts with the design builder early in the project planning process to manage and assume financial responsibility for all aspects of the project. On large, more complex projects the owner may wish to hire a criteria architect to establish conceptual design parameters. Once initial project parameters are defined, the design build team can generate schematic designs and a preliminary guaranteed maximum price including a design contingency. In some instances the design builder will pre-select the mechanical and plumbing contractors to provide design and engineering services on a design-assist basis. The design builder and team will fix the design and construction compensation and procure all subcontracts and other services, sharing all bid and cost information with the owner on an open book basis. The cost, schedule and other project specifics are defined and updated at the design and construction document phases.
