Factors for optimizing time performance of Modular Construction: a review and evidence from Huoshenshan Hospital construction

Modular Construction is one of the emerging construction technologies, which play an important role in saving construction time and have gradually become a hot topic in the field of construction. In order to further understand the advantage of Modular Construction in terms of time performance, the research aims to identify key factors that can affect the duration of Modular Construction projects. Based on the literature review of 23 related papers, 13 factors that have significant impacts on the duration of Modular Construction have been identified and summarized into five categories, namely cooperation among stakeholders, design, construction, abundant resources, and the support of the government. How these key factors have shortened the duration of Modular Construction in practice is also explained by the case of Huoshenshan hospital, a well-known emergency hospital built for COVID-19 in China, which used the Modular Construction method.
