description

This dissertation presents the evaluation of an onsite augmented reality tool and its relevance for helping construction agents to prepare and monitor the progress of a building's construction or renovation through a mobile device. The case study focuses on virtual renovation works regarding an ancient window –dated eighteenth century- in a room of the Cluny (Saone et Loire, France) abbey buildings. The study aims at comparing the efficiency and the precision of users' behavior in four situations while performing identical sets of tasks. Three methods related to the ICT uses of onsite AEC (Architecture, Engineering and Construction) guided the experiment: the first method focuses on paper-based content; the second method provides a digital model of the project on a workstation. The third method consists in using a full digital model with colocation access to the database on a mobile device. The fourth method considers working in an immersive room to interpret thermal simulation data. The result of this work is dedicated mainly as a decision-aid tool for project owners and constructors. The comparison between these methods led to a first experiment whose results favor the second method, which implies working on a desktop workstation. However, beyond the aspect of ergonomics and user interface, further investigations are necessary to study the propriety of using the Building Information Model (BIM) on the construction site.
