Rebuilding Woolwich Arsenal clock tower, London, UK

In October 2008 the £70 million Warren Development at Woolwich Arsenal in London, UK was 90% complete when the historic clock tower suffered almost total destruction following impact by a large earth-moving digger. The project team employed rigorous investigation, traditional detailing, minimal intervention and detailed analytical techniques in the restoration. This case study takes a chronological journey through the events following the collapse to the completed restoration. At each stage the attention to conservation best practice is emphasised as empowering the entire reinstatement process. The following aspects are covered in detail: initial assessment, background research, survey, salvage, logging, testing, modelling, analysis, scheme design, interrogation of proposals, appropriate detailing, reconstruction and finishing. Through cross-referencing to conservation guidelines the author provides the argument that it is the attention to conservation best practice that allows the successful delivery of this sensitive restoration project both in terms of heritage and cost effectiveness. The project reinstated 85% of the original materials of the clock tower and helped ensure its future. This project was shortlisted for the ICE 2011 London Heritage Award and inclusion in Open House London.
