IWA Plant 2 Condition Assessment
Kelsey Structural performed the structural condition assessment of the IWA Plant 2 facilities including two well structures, a booster pump station and welded steel reservoir. Work included structural site investigations at each facility to document structural condition, complete seismic analysis of each facility and a comprehensive series of technical memoranda summarizing the assessment findings with corresponding improvements recommendations and preliminary cost estimates. The results of the assessment identified several critical structural elements as being deficient in terms of seismic performance and current code requirements, with recommendations being made for complete replacement of the existing booster pump station along with seismic retrofits to one of the existing well facilities and lowering of the maximum operating water level in the reservoir to provide sufficient freeboard to allow for sloshing.
