Portland, Oregon’s Alternative Contract Approach to Tackle a Complex Undergound Project
Abstract
This paper discusses the process utilized by the City of Portland Oregon’s Bureau of Environmental Services (BES) to procure and compensate Impregilo-SA Healy (I/H) for the West Side Willamette River Combined Sewer Overflow (CSO) Project. The contract method is a three-phase process consisting of qualifications based contractor procurement, pre-construction phase design assistance/construction planning, and facility construction where the contractor is compensated on a cost reimbursable-fixed fee basis.
The paper focuses on pre-construction phase lessons learned from the development of the contract general conditions, establishment of a construction budget and cost control program, incorporation of contractor recommended design changes, and development of a subcontractor procurement program for construction.
