The construction industry generates a large amount of “construction and demolition waste”, given little attention is paid to material recovery. As a key strategy, the widespread implementation of building materials reuse has suffered from information deficiencies, which can be potentially improved with digitalisation. Therefore, the PhD project aims to support information flow in reuse processes throughout digitalisation in the built environment, especially under the context of renovation and demolition projects. The leading study seeks to understand the challenges and opportunities that contribute to improper information flow in demolition projects, while the other studies focus on providing support for specific challenges.
