DESIGN-BUILD EXPERIENCE FOR THE CITY OF DELAWARE, OHIO WATER RECLAMATION FACILITY
Abstract:The City of Delaware is located in Central Ohio, approximately 20 miles north of Columbus. The City of Delaware has seen a 26% increase in population from 1990 to 2000. It is estimated that the population will increase by 25% to 31,500 in 2010, and then by another 30% to over 41,000 by 2025.
For the above reasons, the City has recently completed a water reclamation master plan to create a roadmap for the City's future wastewater treatment needs. It was concluded in the master plan that the existing facility should be expanded to 10 mgd at the existing site. The overall cost of the proposed expansion was estimated at approximately 15 million dollars, which represents a very large project for the City of Delaware. Therefore, the City decided to pursue an alternative capital projects delivery method in hopes of saving both time and money.
It was decided that the design engineer would provide conceptual documents, the aggregate of which would be approximately 30% complete. Although the overall project will only be approximately 30 percent complete when proposals are requested from the short-listed design build-teams, the project will be very well defined with regard to processes, tanks sizes, and types of equipment. It will actually be considered to be nearly 100 percent complete from a process standpoint.
The process to select the design-build team for this project is a two-step process. In the first step, statements of qualifications (SOQs) were requested from potential design-build teams. Based on qualifications including financial capability and condition; key staff experience and past performance; and the design build team/company experience and past performance; the three to five most qualified teams will be invited to submit detailed proposals. The most qualified team will then be selected based on SOQ evaluation criteria; technical approach; and price.
To date, response to the design-build concept for the City of Delaware project from the engineering and contracting community has been generally positive. However, the City of Delaware will not know until the project is completed whether or not utilization of an alternative delivery method was in their best interest.
