CSEE is celebrating its 12th anniversary, marking more than a decade of bringing together researchers and professionals to share research and developments in civil, structural, and environmental engineering. This civil, structural, and environmental engineering congress proceedings will be published with an ISSN and ISBN, indexed in Scopus, Google Scholar, Semantic Scholar, and archived permanently in Portico. The congress is composed of 3 conferences. While each conference consists of an individual and separate theme, the 3 conferences share considerable overlap, which prompted the organization of this congress.
