Abstract

Construction processes happen in partially controlled environment; resulting in prefabricated components being vulnerable to variances resulting from deviation in quality of work put in place. However, wider adoption of VDC methods and advances in Reality Capture technology has opened up avenues for adopting prefabrication in construction projects by enhancing predictability using two methodologies. First, the use of advanced VDC methods to create highly detailed and coordinated models. Second, incorporating deviations in installed/existing building components using as-built 3D models created from laser scans of the construction site. This paper focuses on case studies of commercial projects in the USA that have prefabricated interior wall partitions, resulting in higher productivity and quality. Further, it would outline the processes and workflows used by a global team, located in the USA and India; concluding with quantitative and qualitative benefits observed on these
