Automation of building information modelling process of sanitary drainage system with Dynamo


The aim of this project is to design an adoptable solution that improves the quality of work and increases work productivity for the modelling of inspection chambers, waste sumps and manholes, and their pipe connections in Revit. Existing workflows and design requirements of the sanitary discharge system at a consultancy firm were analysed. Since the aim of the project is to address a practical problem, the mixed-methods research (MMR) overall approach was employed for this study. The MMR was conducted across four phases with different approaches used for data collection and analysis. Phase 1 involves understanding existing workflows and the design requirements of the sanitary discharge system the existing Dynamo workflow used at the consultancy firm managed to generate pipe connections. Phase 2 involves evaluating the performance and user experience of existing workflows. Phase 3 involves the creation and development of the solution. Phase 4 involves evaluating the performance and adoptability of the solution – the new Dynamo workflow. The new Dynamo workflow developed in this study provided users a better work experience than the existing modelling workflows. The new Dynamo workflow significantly reduced labour hours required for completing the given modelling tasks accurately.

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 is currently researching to develop an understanding that provides direction for educating learners on how to solve sustainable building value delivery problems. He engages in research for education because he wants to contribute to the human empowerment needed to improve industry practice and healthy living. Under the sustainable building value delivery theme, he focuses on indoor air quality value delivery and value-oriented productivity in sustainable building design, construction, and management practices. His research for education effort is enhanced by his fundamental knowledge and skillsets in building information modelling and other digital solutions adoption, design, critical, reflective, scientific, and lean thinking, fine art, oral and written communication, and storytelling. He has published more than 200 applied learning, discovery research, and literature review articles and creative works (fine art and creative writing) to develop an understanding of solving sustainable building value delivery problems. 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.
