A BIM model to visualize quality risks in construction projects

Defects are a non-value adding activity seriously affecting the performance and productivity in construction projects that spend unnecessary cost, time materials and manpower. Non-quality represent the 4% of the contract value of the new dwelling or renovation and produce other adverse consequences such as temporal deviations, affectations in project sustainability as well as safety and reduction ofproject performance. Developing tools that bring awareness ofthe potential quality risks can help organizations improve their quality performance. Moreover, there are significantly growing evidence linking BIM benefits to decision-making tools. This paper presents the implementation of a quantitative methodology to forecast potential quality risks into a 40 model (BIM-QRC). BIM-QRC proposes 40 multiple views related to the needs of each practitioner. The methodology ranks the significance of all quality risks of a construction project and is able to compare several design options in terms of quality performance. While the existing methodology is useful to get consciousness ofthe quality risks of a project, the adaptive visualisation of different business views improves the understanding and comprehension of the quality performance of a project and facilitates decision making for both designers and contractors.Peer Reviewe
