The digital preservation of national memorial architecture: A new approach with BIM and VR technology

Abstract

National memorial architecture serves as a testament to civilization, embodying and perpetuating a nation’s culture, values, and identity. It facilitates the preservation of historical events or memories for future generations to reference while symbolising national pride and unity. However, the conservation of such monuments currently faces numerous challenges, including the impact of unforeseeable forces, excessive tourism, and inadequate funding. In response to these challenges, this paper proposes a solution utilizing Building Information Modeling (BIM) and Virtual Reality (VR) technologies for digital preservation. BIM enables comprehensive data collection of commemorative structures, while VR provides immersive virtual experiences, enhancing public understanding and engagement with these monuments. Using the People’s Heroes Memorial Tower in Zhangcun, Siming Mountain Martyrs Cemetery, Ningbo, Zhejiang, China, as a case study, this paper demonstrates the entire process of digital preservation and explores the potential applications of these technologies in safeguarding national memorial architecture.
