The National Institute of Science and Technology (NIST) has recognized that the U.S. construction industry has room for large productivity gains. NIST has also recognized that the increased use of prefabrication in construction projects may be one way of attaining these gains. This research has been conducted to investigate the available productivity gains and appropriate applications for one form of prefabrication, which is multi-story modular construction. The research identifies vertical expansion as a potential application for multi-story modular construction methods. In the research, the design process for a modular expansion is mapped out and a case study is used to help identify factors that can impact the feasibility of implementing modular construction methods for the purposes of vertical expansion.
