Design for Manufacturing and Assembly (DfMA) Checklists for Off-Site Construction (OSC) Projects

Off-Site Construction (OSC), which has the advantage of improving construction productivity, is being spotlighted as a solution to limitations conventional production methods. Despite need for, and various advantages of, introduction utilization OSC, however, several issues remain, such design errors reduction in completeness, due lack experience expertise project participants, well improper consideration environment technical constraints. To resolve these issues, it necessary develop an optimal plan that conforms OSC manufacturing efficiency; thus, there have been ongoing efforts industry introduce Design for Manufacturing Assembly (DfMA), derive plans projects. Some studies related application DfMA conducted, however they neglected present checklist reviewing optimality plans. This study therefore developed OSC–DfMA checklist, review projects, by listing goals process, principles. utilized systematic literature review, structured interview, content validity analysis methods presented herein.
