Description | The existing fermenter was constructed during the 2007-2008 Phase 1 Improvements Project. Following initial construction, the one-year warranty inspection revealed the coatings on the concrete were delaminating. The coatings were removed and completely re-applied after the one-year warranty inspection. The City wished to ascertain the condition of the structural and mechanical components of the fermenter after over a decade of nearly continuous operation. A condition assessment of the structure was performed in July 2020. The fermenter was emptied and cleaned prior to the inspection. The condition assessment evaluated the fermenter concrete, concrete coatings, piping, hardware, equipment, launder, ventilation system, and access points. The initial assessment of the fermenter yielded some insight into the condition of structure and equipment, but further assessment is required to determine a final rehabilitation scope. Areas of contaminated concrete were discovered as well as section loss of interior steel components. Several testing procedures and a follow-up assessment are required to better understand the condition of the structural components of the fermenter and devise a final rehabilitation strategy. |
