including participants ’ position and gaze , improves communication and collaboration efficiency .
ii ) Seamless Translation In every construction project , there is a decisive process , in which design is transformed into reality , abstract ideas are translated into physical objects . As almost every project is unique , site-specific and labour-based , intensive and accurate “ translation ” of the design information is required . The current translation process of turning design documents into reality is a constant struggle . It is a complex cognitive process in which wrong interpretation of data often leads to costly errors , quality issues and rework .
Digital 3D models reduce the level of abstraction and help clarify the design intent , but still , at the execution stage , there is a clear boundary between documentation and the real world . Mixed Reality technology blurs this line . With Mixed Reality , the information is superimposed on the physical environment . This minimises the need for translation and reduces subjective interpretation .
The user visualises the design in context , and can better understand , interact with and execute the required actions in real time . The immediate visual feedback also supports a more effective production control process . Overlaying design on as-build structures reveals any deviation and provides immediate feedback .
iii ) Extending the Digital Thread Integration of business workflows and improved communication are clear goals in today ’ s AEC industry . The silo structure and the need to re-create data , when moving from one stage to the other , are still sources for major inefficiencies . Project delivery methods like IPD and technology changes such as Building Information Modelling ( BIM ) support this trend and have proven to positively impact project quality , cost and schedule . Mixed Reality technology supports integration and collaboration along three main axes :
The Project Stage Axis : Design to Build ( and Operate ): Moving along this axis , Mixed Reality brings 3D data to life and puts information in the user ’ s hands without the need to change or adjust the data format . A sign-off BIM model can be projected in context to guide
