This is the first time a project will have been delivered by the Parliamentary Strategic Estates’ using Building Information Modelling (BIM).
Purcell has been appointed by Strategic Estates as architects for the essential conservation repairs and refurbishment to the external fabric and internal spaces of the Elizabeth Tower. Arguably the UK’s most famous landmark, the project is being delivered using BIM level 2, to digitally model the site and manage construction logistics around the tower during the works.
A programme of works is carried out on the tower every 25 years, due to the need to maintain the cast iron roofs, clock and stonework. Using this technology, highly accurate 3D models allow the team to develop and test their innovative design solutions before construction. The proposed work includes repairs to the cast iron roof, clock faces and other high level metalwork, water proofing the belfry tower, external stonework conservation, installing a lift and comprehensive re-servicing.
The repair and design philosophy was developed based on conservation excellence and a minimal intervention approach to ensure the integrity of the historic building. The design team is developing creative solutions in order to carry out the works in the limited space with restricted site access, while minimising any disruptions to the business of Parliament.
