Description
The project involves the removal and replacement of four existing 24-inch discharge pipes at the Kellogg Creek Influent Pump Station, located at the Kellogg Creek Water Resource Recovery Facility in Milwaukie, Oregon. The work includes demolition and removal, pipe replacement, concrete wall restoration, flap gate refurbishment, testing, and site restoration. The project requires a minimum of two discharge pipes to remain in service at all times during construction, and the contractor is responsible for maintaining the required minimum flow capacity throughout construction.
• The existing discharge pipes are approximately 10 feet in length and run horizontally between two concrete walls.
• The pipes are currently exposed and accessible via hatches above the pipe corridor.
• The project requires the contractor to core, cut, or otherwise remove the concrete as necessary to extract the existing embedded pipe sleeves and wall penetrations.
• The base quote pipe material shall be lined ductile iron with a shop-applied exterior corrosion protection system.
• Quoters are encouraged to also provide alternative pricing for 316L stainless steel and/or coated carbon steel.
• The project estimate is $150,000.00, and the work must be substantially completed no later than September 30, 2026.
