Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it?s actually built.The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase. VDC has also been investigated in order to identify the weaknesses in this technology and an assessment has been made as to how these can be eliminated and hence how VDC can be improved. Based on that this thesis has been carried out with the following main question: How can augmented reality be implemented in the construction industry and how can it become integrated with VDC in order to achieve a streamlining effect in construction?The theoretical background is based on a literature study where information about augmented reality has been collected from technical reports from all over the world. A study of the technology behind augmented reality and its possible areas of application as well as a description of the future possibilities and ongoing research has been made. VDC has only briefly been examined in the literature study. Interviews with construction staff and experts within AR and VDC have been conducted in order to obtain a basis for an analysis of the current situation. Based on these interviews gains and shortcomings of the VDC technology have been identified, and requests for the AR technology?s future applications have been plotted.The result of the literature study is that a positioning technique that is more accurate and more robust than the ones on the market today needs to be developed in order for the AR-technology to work properly. There are a number of beneficial areas of application for AR in construction given that the previously mentioned problem is overcome. VDC in construction brings substantial benefits in terms of financial and time savings. It serves the communication between design and construction.AR will be easier to use for marketing purposes and early stages of projects than in construction. As for VDC more focus needs to be put on the implementation of the technology to a broader crowd rather than developing the technology further in a small group of experts.In order for augmented reality to be implemented in the construction industry VDC and its support need to be further developed towards construction before yet another technology is introduced. Augmented reality will not solve the shortcomings of VDC today.
