Brief of the session
Academic communication with experienced scholars is important for current RPG students to enhance research skills and acquire domain knowledge. Therefore, CIB HKU Student Chapter organises the research sharing session inviting extraordinary young scholars internationally to share their latest research efforts. This time, we gratefully invite Dr. Thilini Jayawickrama and Dr. Chao Chen to present their research outcomes and experience via an online meeting. They are professionals in the fields of sustainable construction and computer-aided building engineering, respectively. They will introduce how they designed, conducted and validated their research, difficulties they faced and how they were overcome, and the impact of their research outcomes. If interested, you are most welcome to join this online session!

Introduction
Speaker 1: Dr. Thilini Jayawickrama, an Online Course Facilitator for the Construction Management Program in University of South Australia Online
Title: Re-visiting environmental assessments for approaches enhancing natural capital
Abstract
Environmental assessments including multi-criteria rating systems are widely adopted in construction with major focus on minimizing negative environmental impacts in terms of waste management, efficient use of energy, water and other resources. However, less attention is paid on positive impacts of enhancing natural capital stocks and conserving biodiversity. With the current rate of natural resources depletion, the existing natural capital stock will not be able to provide sufficient environmental resources and services for the survival of economies and societies. Also, the importance of integrating natural systems in built environment is increasingly recognized for the human wellbeing. It’s time to revisit environmental assessments to acknowledge approaches that enhancing natural capital stocks and conserving biodiversity thus, promoting such practices in construction projects.
About the speaker
Dr Thilini Jayawickrama is an Online Course Facilitator for the Construction Management Program in University of South Australia Online. After graduating with BSc (Hons) in Quantity Surveying in University of Moratuwa, Sri Lanka, she completed her PhD in National University of Singapore. She is a former Senior Lecturer in the University of Moratuwa, Sri Lanka and has worked as a Quantity Surveyor in a leading construction company in Dubai, UAE. Her research interests lie in sustainable construction and environmental assessments.
Speaker 2: Dr. Chao Chen, a Post-doctoral Research Fellow in Department of Real Estate and Construction, The University of Hong Kong
Title: Development of low-cost mobile laser scanning for 3D construction indoor mapping by using inertial measurement unit, ultra-wide band and 2D laser scanner
Abstract
This study introduces an innovative mobile laser scanning (MLS) method for 3D indoor mapping. The generally accepted and used procedure for this type of mapping is usually performed using terrestrial laser scanning (TLS) which is high-cost and time-consuming. Compared with TLS, the developed method shows advantages of low-cost, high mobility and time saving on the implementation of 3D indoor mapping. It integrates a low-cost 2D laser scanner with two indoor positioning techniques – ultra-wide band (UWB) and an inertial measurement unit (IMU), to implement a 3D MLS for reality captures from an indoor environment through developed programming algorithms. A reference experiment by using conventional TLS was also conducted under the same conditions for scan result comparison to validate the method’s feasibility.
About the speaker
Dr. Chao Chen obtained his PhD degree in Architecture & Built Environment from University of Nottingham in 2019. He also has MSc degree of Distinction in Electric, Electronic & System discipline in Loughborough University and BEng degree of Architectural Environmental Engineering from University of Nottingham. Currently he is a Post-doctoral Research Fellow in Department of Real Estate and Construction, HKU. His research direction is the integration of BIM, AI and blockchain.
