KanBIM Workflow Management System: Prototype implementation and field testing

Abstract

Research Question: can a BIM-based workflow information system help construction personnel implement lean pull flow strategies? If so, how, and to what extent? Purpose: to test a prototype system in the field, measure and monitor its impact, and evaluate and discuss the implications. Research Method: we have implemented an early prototype of a novel workflow management information system for construction, called ‘KanBIM’, and tested it on a large residential construction site in three stages. Findings: the main significance of the results lies in the site personnel’s positive experience with the system and their observations of the ways in which it could influence the behavior and productivity of crews. These included recognition of the effect the system had in encouraging well-informed discussion and negotiation between crews concerning coordination of work. Limitations: although PPC and other quantitative measures were collected, the duration of the field tests and the depth of integration in company information systems insufficient to provide conclusive results. Implications: while the results are positive and indicate the value of BIM-enabled process flow control, further development and testing is needed. Value for researchers and practitioners: the prototype and the findings are an essential guide for future development of lean process flow control systems. We identify specific benefits a full implementation could bring to subcontractor trade managers, superintendents and other project management functions.
