Development of a mobile phone-based application for detection and communication of building defects


Accurate detection of building defects and communication to stakeholders with prudent use of invested resources, e.g., time, manpower, and money, increases value delivery to all stakeholders involved in the building delivery. This paper presents a prototype developed to facilitate enhanced value delivery for building defects inspection during building construction and management. With image classification and cloud database technologies, this study proposes a mobile (phone-based) machine learning application to raise awareness of building defects located in buildings and the implications to motivate building stakeholders to promptly reduce the risk level. The benefits of the developed prototype can further be enhanced when the developed prototype is integrated with drones. The adoption of the developed prototype will vary depending on the cause and context of the defined building defects detection and communication problems to be addressed.

Dr. Moshood Olawale Fadeyi is a sustainable building professor with specialisation in sustainable building value delivery education at the Singapore Institute of Technology. He is also an architect, an indoor air quality expert, a chartered engineer (UK) – building services, a chartered construction manager (UK), a cartoonist, and a specialist adult educator. He holds four university degrees, including a Ph.D. in Indoor Environment and Energy from the National University of Singapore and the Technical University of Denmark. He is architecture (BSc Arch and M.Arch.), building science (MSc.), and engineering (Ph.D.) trained. He is a member of the Chartered Institution of Building Services Engineers (UK), Chartered Institute of Building (UK), and American Society of Heating, Refrigerating, & Air-conditioning Engineers. He is well suited for architecture, interior design, building science, and architectural/building services engineering education. He has experience and expertise in developing undergraduate and postgraduate curricula to make students job-ready upon graduation. He currently researches to develop creative works and public education materials useful for developing critical and reflective thinking, communication skills, and technical knowledge needed to enhance industry, community, and education practices for solving sustainable building value delivery problems. Under the sustainable building value delivery education theme, he focuses on indoor air quality value delivery education and value-oriented productivity education (in sustainable building design, construction, and management practices). He has published more than 200 research and scholarship outputs in peer-reviewed journals, conferences, books, and public educational resources. His research for education efforts is enhanced by his fundamental knowledge and skillsets in the philosophy of building information modelling and other digital solutions adoption, problem-solving philosophy, design, critical, reflective, scientific, and lean thinking, fine art, oral and written communication, and storytelling. Companies and government agencies highly seek his expertise and leadership skills. He is the Editor, Author, and Cartoonist of Indoor Air Cartoon Journal – a creative and applied learning journal providing education on indoor air quality, with audiences from over 100 countries. He is a former National Taekwondo Champion in Singapore – Black Belt Middle-Heavy Weight category, 2006.
