Supporting a Model for Increased Labor Time Utilization When Engaging Building Information Modeling for Prefabrication

摘要

Utilizing a building information modeling (BIM) based workflow process, this paper, embedded in a case study environment, defines a workflow model to increase modeling labor time utilization for project teams engaged in prefabrication and installation validation of building components. Through participant observation and structured research methods, the findings highlight the importance of various scheduling techniques, model, and data management procedures, communication protocols, and reality capture processes. This research provides a process framework in which workflows can be streamlined and modeling team labor time utilization rates increased. The increased utilization rates positively impact downstream installation of prefabricated components based upon the coordinated construction model. Additionally, this paper identifies and defines the importance of varying typologies of geometric information within a building information model used for prefabrication in a constrained construction environment. In conclusion, this paper defines an ideal-state project workflow for successfully engaging in BIM-based prefabrication and installation validation in ever changing construction field conditions.
