The City of Portland, Oregon, is using a hybrid contracting scheme that combines the scheduling advantages of design/build with the control of a construction manager arrangement to construct a multiphase solution to its combined sewer overflow problem. The method is enabling contracts and engineers to work together to find alternative methods of construction that save both time and money.
