Carrasquillo Associates (CA) was retained in 2014 to investigate unusual wear on crane rails in a steel processing plant in Pennsylvania. CA conducted an on-site investigation to measure the severity of the crane rail wear and to determine its cause. Custom crane rail measuring devices were fabricated at a machine shop in Austin, TX for this purpose. In addition, CA reviewed numerous surveying reports to verify dimensional compliance between laser surveys, project specifications and industry standards. Life cycle estimates of the crane rails were made based on the information collected during the site visit and research conducted by the US DOT.
