Abstract
When the outer walls of buildings are retained while the main building is demolished and replaced by a new structural frame, a retained facade results. The challenges created by this method of construction are unique and this paper focuses on the technical and managerial issues relating to this approach. It identifies options for developing existing buildings ; reasons for employing retained facades; and important technical considerations which need to be addressed by designers and contractors, including temporary support, connection between facades and new structures, strengthening a facade's existing foundations and design of new foundations for these facades. Some of the major management implications of retained facades are also described. These include contractual issues, surveys, inspections and monitoring of facades, access and safety, programming and statutory control. The paper is based on case studies of contemporary construction projects, surveys of construction engineers and managers, and relevant literature.
