Appropriate Technologies for Conservation

Abstract Conservation principles rarely consider the technology of either the historic artefact itself or of the technologies to be used in conservation. This paper argues that the principles adopted should be appropriate to the technology of the construction, partly to preserve the integrity of the original design, but also partly for sound practical reasons. This is particularly true of more recent and somewhat transient technologies. It also considers the advisability of using some sophisticated techniques to stabilize existing structures when more traditional repair methods, even perhaps including rebuilding, might be more appropriate. This requires a more flexible approach and a clearer evaluation of the historical significance of the existing fabric. Moreover, for sensible judgements to be made and appropriate methods of repair to be selected, it is necessary that the technologies of construction be understood.
