“Evaluation of Earthquake Damage to a Flood Protection Levee System at a Central
American Banana Plantation”


A seismic event located off the northeastern coast of Central America resulted in damage to an earthen flood protection levee system. An insurance claim by the owner provided anassessment of areas within the levee system that warranted repairs. The purpose of our services was to evaluate the insured’s categorization of damages and to provide an independent opinion based upon our observations. Our assessment of the site conditions involved walking approximately 60 kilometers of the levee system, photographically documenting our observations, and using global positioning system (GPS) devices for location purposes. Our conclusions generally concurred with the owners initial assessment and actually provided additional lineal footage of the levee system to be included for repairs.
