Abstract
Despite the efforts for sustainability studies in building and infrastructure construction, the sustainability issues in industrial construction remain understudied. Further, few studies evaluate sustainability and benchmark sustainability issues in industrial construction from a management perspective. This study presents a phase-based benchmarking framework for evaluating sustainability practices use focusing on industrial facilities project. Based on the framework, this study quantifies and assesses sustainability practices use, and further sorts the results by project phase and major project characteristics, including project type, project nature, and project delivery method. The results show that sustainability practices were implemented higher in the construction and startup phases relative to other phases, with a very broad range. An assessment by project type and project nature showed significant differences in sustainability practices use, but no significant difference in practices use by project delivery method. This study contributes to providing a benchmarking method for sustainability practices in industrial facilities projects at the project phase level. This study also discusses and provides an application of phase-based benchmarking for sustainability in industrial construction.
Highlights
Construction is a major industry in the global economy
Since the nature of a construction project may affect the level of sustainability practices use, this study assessed the level of sustainability practices use in each project phase by project nature and investigated its difference using Analysis of Variance (ANOVA) test
This study finds that the brown field projects tend to implement sustainability practices more than the others in front-end planning and construction phase when comparing four projects nature because the brown field projects build a facility on the area where another facility was already constructed and demolished
Summary
Construction is a major industry in the global economy. In 2015, the global construction market reached US$9.5 trillion, accounting for more than 10% of global gross domestic product (GDP) [1]. Within the global construction market, industrial construction accounts for 21% [1], but sustainability studies have usually focused on the other two sectors, building and infrastructure. Industrial construction is usually the most complex sector, and involves more dangerous facilities. If sustainability issues, such as environmental or safety accidents, occur in an industrial project, the impact is more severe than for building and infrastructure projects. Industrial construction projects require sustainability management practices to minimize negative environmental impacts throughout the project delivery process for industrial facilities
