BIM-augmented reality integrated approach to risk management

Abstract

Despite the acknowledged promises of adopting technologies such as BIM and AR, research addressing the challenges and opportunities of such synergies in cost and schedule risk management is still limited. This paper contributes to the literature by presenting an integrated, proactive BIM-Augmented Reality (AR) risk management system enabling an online inspection of project cost and schedule risks. This system records the actual risk data (e.g., risk type and likelihood) using AR on commercial smartphones, runs an online Risk Failure Mode and Effects Analysis (RFMEA), and updates the project's BIM model to provide informed risk-related solutions. A case study is provided to demonstrate the implementation of the proposed system in a real project. Despite the challenges cited in the post-implementation survey (e.g., system ergonomics and synchronizations of automated/non-automated subsystems), 67% of the users acknowledged the improvement in cost and schedule risk management owing to enhancement in communication, timeliness, and risk perception.
