Exploring the Potential of iPad-LiDAR Technology for Building Renovation Diagnosis: A Case Study

Abstract

Digitalization and sustainability are twin trends in the construction industry (CI). Mobile devices are becoming more and more powerful, gaining the ability to support tasks that, until recently, were unthinkable. One example is LiDAR. The use of this technology embedded in tablets and smartphones brings new possibilities at a scan-to-BIM level. Given the commitment to circularity, waste audits will become mandatory for renovation projects. This is a heavy task that can benefit from existing processes and from digital technologies. This paper aims to demonstrate how everything is related and can be efficiently combined. The research convenes digital transition, green transition, circular economy, waste audit, LiDAR, and design processes' improvement. A mixed-methods approach aims to demonstrate how it is possible to establish digital waste audits and how these can become the core of the diagnosis process to be made during strategic definition or as part of the renovation design's initial actions. LiDAR technology embedded in mobile devices is worthy and can bring major improvements to the diagnosis phase. This will become more compliant with objectives set for digitalization and improved sustainability, contributing to the sector's twin digital and green transitions.
