Peter is an Associate Director in the Development and Project Management team at Rise4. The consultancy specialises in key sectors — including hotels, Oxford colleges, universities, high-end residential and commercial. Peter will present a case study in the removal of Reinforced Autoclaved Aerated Concrete from internationally significant Grade I listed buildings at St Catherine's College.
Since September 2023, the College has restricted access to various areas within the College due to the presence of RAAC in the College’s roof structures, principally the original Grade I Listed Arne Jacobsen site. This included the Kitchen, Dining Hall, JCR, SCR, Administration Block, Wolfson Library, the Bernard Sunley Building and the top floor of the Accommodation Blocks Staircases 1 to 16.
The complexity of this project is driven by the fact that many of the impacted buildings are Grade I Listed, therefore requiring sensitive design and extensive consultation with the Local Planning Authority and Heritage England. In October 2024, the College signed a construction contract with Beard to begin the remediation works and work is now on site.
