REQUEST FOR PREQUALIFICATION APPLICATIONS
FOR LAKE OSWEGO INTERCEPTOR SEWER – LAKE DOWN CONTRACT

The City of Lake Oswego, Oregon requests prequalification applications from interested contractors to construct the Lake Down Contract, one phase in the multi-phase project to upgrade the existing Lake Oswego Interceptor Sewer. This application is for the Lake Down Contract, for which prequalified contractors will be invited on December 16, 2009 to submit bids by February 17, 2010.  Approximate cost of the Lake Down Contract is $20 million to $30 million.  Work is expected to begin in March 2010 with the drawdown of Oswego Lake to begin in September 2010. Lake refill begins in January 2011 with completion of construction in April 2011. Prequalification will be required of all general contractors and specialty marine and bypass pumping contractors wishing to perform work on the Lake Down Contract.

Sealed Prequalification Applications must be received by 2:00 P.M. PST, November 4, 2009 by Joel B. Komarek, P.E., Project Director, City of Lake Oswego, P.O. Box 369, Lake Oswego, Oregon, 97034.  Copies of Applications for Bidder Prequalification are available for $50.00 on September 30, 2009, at 9 a.m. PST by contacting Willamette Print and Blueprint, Inc. at: www.wpbinc.com\content\digital_planroom or by phone at (503) 223-5011.

The new interceptor will be a gravity system, constructed of fused high-density polyethylene (HDPE) pipe.  It will be held in place by pile supports near the shoreline and by a buoyant tethered system using ground anchors and stainless steel wire rope in the deeper portions of the main lake. More information can be found on the project website at www.lakeinterceptor.com.
The Lake Down Contract involves the installation of pile supported and buried pipe to connect pipe previously installed during the first phase of Work (Lake Full Contract) to the City’s existing sewer system.  The Work consists of, but is not limited to, all labor, materials and equipment needed for installing pile caps, installing concrete manholes, installation of previously fused large-diameter HDPE pipe that has been sunk to the bottom of the lake to be supported by piles or buried, installing a cathodic protection system for the steel components of the pipeline, and bypass pumping existing interceptor flows.  Work will be conducted in drawn-down lake conditions with the lake surface at several different water elevations that range from a 22-foot drawn down to lake full (MSL 76.6 feet to 98.6 feet):

Lake Down Project work includes: 

  • Pile Caps:  Approximately 224 steel pipe caps to be fabricated and installed on piles installed during the Lake Full Contract.
  • Concrete Manholes:  23 concrete manholes and concrete structures to be constructed and installed.  11 in-lake manholes will be supported on grade and with ground anchors, 4 manholes and concrete structures will be supported by piles, and 8 manholes and concrete strucutures will be constructed on-shore.
  • HDPE Sewer Pipe Installation:  Approximately 7,322 feet total, including 5,178 feet of pile supported pipe and 2,143 feet of buried pipe.  Sewer pipe sizes range from 42-inches to 8-inches in diameter.  Pipe 22 inches and larger will be fused and sunk to the bottom of the lake by the Lake Full Contractor prior to the Work.
  • Earthwork for HDPE Sewer Pipe Installation:  Approximately 5,000 cubic yards of neatline excavation, 650 cubic yards of neatline over-excavation, 1,000 cubic yards of neatline select fill for bedding and backfill, and 4,400 cubic yards of material to be hauled out of the lake.
  • Temporary Sanitary Bypass Pumping:  Approximately 24 indivual temporary pump stations with flows ranging from over 6,000 gpm at several locations for the existing interceptor bypasses to under 5 gpm for many lateral lines.  Fused HDPE will predominately be utilized for bypass pumping piping, lengths may range from 100 ft to 4,400 ft long.  The duration of each bypass pump station will vary depending on the work conducted, ranging from 2 weeks to  6 months.
  • Cathodic Protection System:   Cathodic protection for approximately 337 piles and pile caps including power drops, cable, and rectifiers.
  • TV Inspection:  TV inspection of the interior of new in-water HDPE piping to assure design grade is achieved within tolerances.
