9 December 2021 (Online conference) Editors: Zul-Atfi Ismail, Fahmi Muhammad Ridwan, Che Zulzikrami Azner Abidin, Nur Soleha Abdul Rahim, Noor Ainee Zainol, Nurfadzillah Ishak Organiser: Faculty of Civil Engineering Technology, Universiti Malaysia Perlis, Perlis, Malaysia PREFACE International Conference on Civil and Environmental Engineering (CENVIRON2021) is the fourth CENVIRON conducted since the first conference in 2017. The initial purpose of the conference is to gather researchers, academia and industries in a platform to exchange views, share ideas and discuss current researches in the field of civil and environmental engineering. This include current research and development especially in the advancement of various scope related fundamentals and applications. This conference is expected to spur a fruitful debate and discussion, scientifically bring fresh ideas and at the same time, create a networking opportunity and strong collaboration between the participants. Due to the COVID 19 pandemic, unfortunately, we have reached an agreement to opt for a virtual conference instead of the planned physical conference in the metropolitan city of Penang, Malaysia. Since the pandemic in Malaysia is still unstable and shows no sign of settling soon, and no mass gathering is allowed, this would be the best choice as to put everyone’s health a priority. Despite that, our team has managed to meet regularly via face to face discussions and virtual meetings, in order to ensure the quality of the conference and manuscript is not compromised. The conference was officiated on 9th December 2021 by the UniMAP’s Vice Chancellor, Prof. Dr. Zaliman Sauli at Auditorium of UniMAP Chancellory Building with minimal physical attendees among the conference organizing committee member to allow for social distancing, and with more than 60 attendees following through Google meet platform. The opening ceremony was broadcasted live via UniMAP’s official Facebook page. Two esteemed keynote speakers were invited for the plenary sessions, i.e., Dato’ Seri Ir. Dr. Zaini Ujang (Secretary General, Ministry of Energy, Green Technology and Water Malaysia) and the Dato’ Ir. Haji Mohamad Zulkefly Sulaiman (Director General, Public Work Department Malaysia). The online parallel sessions were successfully organised at Tuanku Syed Faizuddin Putra Library, Universiti Malaysia Perlis (UniMAP) using Google Meet platform. Researchers, academicians and students are among the viewers of the virtual conference. The parallel sessions were conducted according to the theme of publication. Details of the presentation schedule were included in the upcoming section. Each parallel session was chaired by an academician in the related field of Civil and Environmental Engineering to ensure smooth and lively discussions. Each session took about 15 minutes of presentation and 5 minutes of Q&A. Overall, 70 papers were accepted for CENVIRON2021 after rigorous peer review process. In summary, the success of the conference is a team effort. I am grateful to all the committee members who worked very hard to make this event a successful one. We would also like to thank all the authors who submitted their papers to the conference, and the reviewers who contributed to the review process, ensuring quality publication of the conference proceedings. We hope that you will find this conference thought provoking and engrossing and that you had a valuable experience sharing ideas with others at this conference.
