SEATTLE, WA, Oct. 3, 2005 -- King County will soon seek proposals on two major contracts to design and build a marine outfall for the Brightwater wastewater treatment system north of Seattle, Wash.
The county hopes to create interest in the project among construction management firms and design-build teams with experience in both deep-water marine outfall construction and nearshore construction.
King County will use a design-build procurement procedure for the marine outfall construction project and plans to advertise the request for qualifications and proposals in spring 2006. Firms and teams will be evaluated through the county's RFQ/RFP procurement process. Those determined to be qualified will then be invited to submit proposals and participate in the remainder of the selection process. King County expects to award the design-build contract by June 2007.
The county is seeking a construction management team to support the outfall design-build project. The RFP for construction management services is scheduled to be advertised in late 2005. The construction management contract is expected to be awarded before the design-build RFP and RFQ are advertised in spring 2006.
Design on the marine outfall is now at 30% completion. As now planned, the outfall will consist of a 60-inch-diameter pipe extending 4,700 feet from Point Wells into Puget Sound. The 500-foot diffuser at the end of the pipe will be about 600 feet deep. The selected design-build team will complete the outfall design.
The total construction cost for the entire Brightwater system, which includes a treatment plant and a 13-mile conveyance pipeline besides the deep-water marine outfall, is an estimated $1.4 billion.
When procurement packages are advertised, they will be available on the King County Procurement and Contract Services Web site at http://www.metrokc.gov/finance/procurement/rfp_rfq_itb/default.asp or by calling Ken Curl at 206-684-1376. King County will not establish a list of potential proposers.
Interested firms are also encouraged to visit the Brightwater project Web site at http://dnr.metrokc.gov/wtd/brightwater/ for more information.
The wastewater-treatment utility now operated by King County has been preventing water pollution for 40 years. The regional clean-water agency serves 17 cities, 17 local sewer utilities and more than 1.4 million residents in King, Snohomish and Pierce counties.
