BRIDGE ENCLOSURE: FACILITATING CONSTRUCTION, INSPECTION, MAINTENANCE, UPGRADING AND OPERATION

Enclosure of a bridge superstructure within a durable outer skin, which also provides access within that skin, greatly reduces many of these difficulties. Enclosure protects the structure and provides safe access for whatever purpose without the need to disrupt traffic above or below. Consequently the authority responsible for an enclosed structure does not need to interface with the other authorities who would otherwise be affected by work on an unenclosed structure. These benefits, both practical and in terms of whole life costing, are illustrated by case studies. Since whole life costing is increasingly being applied in the form of financial incentives/penalties, enclosure is shown to be first cost competitive, as well as economically attractive.
