Report
Summary
The Digester Dome Replacement project is intended to replace the fixed domes covering four of the 14 anaerobic digesters (Digesters 2, 3, 4 and 12). These existing domes are structurally deficient due to age and the corrosive environment within the digesters. The anaerobic digesters are critical to the solids treatment process at the plant. The project will include removal of the existing domes, fabrication and installation of new domes, rehabilitation and coating of the digesters’ interior walls, installation of protective coatings to the interior of the digester domes and installation of roofing material and ancillary equipment on the exterior of the digester domes.
PCL Construction, Inc. will assume the risk of delivering the project through a Guaranteed Maximum Price.

PCL Construction, Inc., may also compete to self-perform limited amounts of work.
