Title
AN ORDINANCE authorizing King County, through the wastewater treatment division of the department of natural resources and parks, to adopt the design-build procedure of public works contracting for construction of the Brightwater marine outfall project.
Body
BE IT ORDAINED BY THE COUNCIL OF KING COUNTY:
SECTION 1. Findings.
A. The King County council adopted the regional wastewater services plan ("RWSP") by Ordinance 13680 on November 29, 1999, which set forth policies intended to guide the county in providing treatment at its expanding plants and in expanding treatment capacity through 2030. The RSWP calls for construction of Brightwater by 2010 to provide needed wastewater capacity for portions of north King and south Snohomish counties.
B. The Brightwater project includes a 36 million gallon per day (mgd) wastewater treatment plant and conveyance facilities to transport untreated wastewater to the Brightwater treatment plant and discharge treated wastewater to Puget Sound through a marine outfall.
C. Constructing an outfall pipeline deep in Puget Sound requires highly specialized design and construction requirements.
D. The department of natural resources and parks and its consultants evaluated traditional and alternative construction project delivery methods and recommended that the marine outfall be constructed using the design-build contracting method. The evaluation determined that having a single entity responsible for both design and construction will minimize, if not eliminate, delays in constructing the marine outfall. The design-build contracting method will also foster scheduling efficiencies by allowing phased procurement/construction of the certain portions of the marine outfall to proceed while design of other project elements is still being completed. A summary of King County's process to select the design-build contracting method for constructing the Brightwater marine outfall is included as Attachment A to th...
