Vibration Modeling


Paul Carpenter Associates, Inc. (PCA) delivers vibration prediction modeling services for a variety of assignments such as rail and construction-related projects. Following the Federal Transit Administration's (FTA) guidance, PCA performs screening and general vibration assessments for public rail clients. PCA possesses noteworthy experience performing operational vibration assessments using approved vibration prediction modeling methodologies for rail realignments, introduction of cross-overs, maintenance facilities, and monorail systems. In addition, PCA commonly utilizes FTA guidance to evaluate the potential for vibration-induced annoyance during construction as well as the potential for structural damage during heavy construction activities such as pile driving, installation of sheeting, blasting and some earthwork activities. PCA performs construction-related vibration assessments for environmental documents and assists in the development of vibration control specifications for large construction projects.
