Looks at the recent Statue of Liberty restoration as a project combining conservation within a larger construction effort. Because the complexities of the construction portion of the project, i.e., a compressed time frame, engineering design considerations, union labor, and the extensive visitor services and island modifications, meant that most work would be accomplished by trade contractors, close supervision and tight specifications pertaining to the historic fabric were necessary. In one case, the contractor was selected on the basis of ability to perform and not on price. Although much of the work done on the skin was accomplished by persons not trained in conservation, the completed project reflected a high degree of care and skill. Training, supervision, and, in one case, the development of a new technique were responsible for achieving the quality of the work. The new technique involved the use of liquid nitrogen to remove paint from the inner surface of the skin. To reach the exterior surface of the copper, a scaffold made of aluminum was erected around the statue in a manner that would not injure or stain her delicate skin.
