Abstract
The objective of this research is to create a comprehensive risk assessment framework for the restoration stage of heritage building rehabilitation in Egypt. Forty-two primary risk factors were gathered from various sources including literature, site visits, and stakeholder interviews conducted during the restoration stage of the Amr ibn al-Aas mosque and Kom el-Shoqafa Cemetery in Alexandria.
