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

Abstract:

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.

Keywords: Building defects, Defects detection, Defects communication, Mobile cloud computing, Machine learning

Assoc. Prof. Moshood Olawale Fadeyi is an Associate Professor of Sustainable Building Value Delivery Education at the Singapore Institute of Technology. He holds four university degrees, including a Ph.D. in Indoor Environment and Energy from the National University of Singapore and Technical University of Denmark. Assoc. Prof. Fadeyi is architecture (BSc Arch and M.Arch.), building science (MSc.), and engineering (Ph.D.) trained. Assoc. Prof. Fadeyi is an architect, an indoor air quality expert, chartered engineer (UK) – building services, chartered construction manager (UK), cartoonist, and specialist adult educator. Assoc. Prof. Fadeyi is a member of the Chartered Institution of Building Services Engineers (UK), Chartered Institute of Building (UK), and American Society of Heating, Refrigerating, and Air-conditioning Engineers. Assoc. Prof. Fadeyi is a complete package for architecture and architectural engineering education in the 21st century. Assoc. Prof. Fadeyi does research for education. From 2018, his research direction that aims to enhance applied learning pedagogy is guided by a question, “How, and why of the how, does the applied, creative (artistic), and case study research done with and for students impact their acquired job-readiness knowledge and skills required to enhance the work process needed to increase the ratio of delivered sustainable building performance usefulness to invested resources?” His expertise and interests guiding his research for education efforts are indoor air quality value delivery and value-oriented productivity (in sustainable design, construction, and facility management practices). The outcomes of his research done with the goal of educating students to be industry-ready are also shared publicly to educate industry professionals and the community. His research for education efforts is grounded in design, critical, reflective, scientific, and lean thinking with digital solutions adoption and storytelling. He has written more than 180 published scholarly and peer-reviewed articles in line with applied learning pedagogy enhancement and provision of scientific evidence on new knowledge. Assoc. Prof. Fadeyi's expertise and leadership are highly sought after by companies and government agencies. Assoc. Prof. Fadeyi is the Editor, Author, and Cartoonist of Indoor Air Cartoon Journal – an applied learning journal providing education on indoor air quality with audiences from over 100 countries. Assoc. Prof. Fadeyi is a former National Taekwondo Champion in Singapore - Black Belt Middle-Heavy Weight category, 2006.
