Forensic Engineering Investigation of PVC Piping Failure in a Multistory Condominium Building

Abstract

Polyvinyl chloride (PVC) piping systems in larger commercial buildings are subjected to greater stresses due to normal building movement when segment length, diameter, and schedule are increased in comparison to smaller residential installations. The likelihood for increased stresses in these system installations must be recognized and accommodated for in the initial piping system design. Performance aspects, such as thermal expansion and building settling, must be considered as well as piping configurations and hanger support placement. This paper addresses the investigation methodology used to identify the causes of chronic building construction defects that resulted in water and mold damage to a recently renovated multistory condominium building.
