Augmented Reality to overcome Visual Management implementation barriers in construction: a MEP case study

Visual Management (VM) is an important Lean method to enhance information flow and reduce waste in construction. However, its adoption is hindered by several barriers. Scientific works mention that emerging technologies can support or replace conventional VM practices, but empirical evidence is missing. Based on an in-depth literature review, we derived the research questions (RQs), arguing if Augmented Reality (AR) could mitigate VM implementation barriers. Thus, a corresponding AR measurement model was developed. Through a case study of mechanical, electrical, and plumbing (MEP) installations in a multi-story apartment building, the RQs were answered using an AR head-mounted display (HMD). To gather the necessary empirical evidence, the data was collected through direct observations on-site and through semi-structured interviews. The study findings show that (1) AR provided time savings and generally satisfactory accuracy levels. (2) AR demonstrably reduced the training effort to better support MEP marking work. (3) The use of AR reduced the resistance to change to adopt VM practices, although concerns were raised about poor ergonomics and work safety risks. Future research activities should consist of investigating the potential of other emerging technologies to overcome the common Lean implementation barriers in construction.
