The International Symposium on Reliability Engineering and Risk Management (ISRERM) was jointly established by Professor Jie Li and Professor Yan-Gang Zhao with support from Professor Alfredo Ang in 2008 to promote scientific development and innovative application of reliability-based, risk-based, or other uncertainty-informed decision making to address all safety related aspects in the management of engineering systems over their design life. The symposium has since been held in Tongji University, Shanghai, China (2008, 2010), Kanagawa University, Yokohama, Japan (2012), National Taiwan University of Science & Technology, Taipei, Taiwan (2014), and Yonsei University, Seoul, South Korea (2016).

The 6th International Symposium on Reliability Engineering and Risk Management (6ISRERM) was held at the National University of Singapore (NUS) between 31 May and 1 June 2018. It is organized by the Department of Civil and Environmental Engineering, NUS, and supported by the ASCE Infrastructure Resilience Division, the Geotechnical Safety Network (GEOSNet), the Institute for Risk and Reliability, Leibniz Universitãt Hannover, the International Association for Bridge Maintenance and Safety (IABMAS), the International Association for Life-Cycle Civil Engineering (IALCCE), the International Association for Structural Safety and Reliability (IASSAR), the International Civil Engineering Risk and Reliability Association (CERRA), the Joint Committee on Structural Safety (JCSS), and TC304 (Engineering Practice of Risk Assessment and Management), International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE).

The symposium theme is “Resilience and Sustainability of Urban Systems”. One of the goals of this symposium is to stimulate discussions on how resilient and cost-effective solutions could be developed to reduce these vulnerabilities by making our complex systems and networks resilient in the sense of preserving and even enhancing critical functions after an expected or unexpected disturbance.The technical programme includes sessions such as “Reliability and Resilience of Critical Infrastructure Systems and Networks” (17 papers), “Global reliability of structures and systems” (10 papers), and “Designing systems for eco-efficiency, robustness and resilience - framework, methods and tools” (5 papers). ISSMGE TC304 contributed 5 sessions (36 papers). This proceedings contains 143 papers from "Australia, Chile, China (mainland, Hong Kong, Macau), Chinese Taipei, Colombia, France, Germany, Ireland, Japan, Malaysia, Netherlands, Norway, Singapore, South Korea, Switzerland, UK, USA", including the Alfredo Ang Lecture and 3 keynote lectures. There are also 4 presentations in a plenary session on “Smart Construction” organized by Prof Hongwei Huang from Tongji University and 4 presentations in an industry session on “Digitization of Civil Engineering” organized by the Geotechnical Society of Singapore (GeoSS). Full papers for these presentations are not included in this proceedings.

The editors are indebted to the authors for the efforts in preparing their papers. We are also grateful for the technical advice and assistance from the session organizers, the International Advisory Committee, the International Scientific Committee, and paper reviewers. Last but not least, this symposium could not have been organized so successfully without the generous financial support from our main (Gold) sponsor, Zhao Yang Geotechnic Pte Ltd 朝陽土地工程私人有限公司 and other sponsors: Geoharbour 上海港湾集团 and Keller ASEAN.
