“…AR has been getting more attention in the construction industry because of its ability to superimpose virtual objects on real world scenes. Several research works have used AR for providing more accurate interactive site visualisation [51], construction worksite planning [52], underground infrastructure planning and maintenance [53], comparison of as-built and as-planned images on construction sites [54], and visualisation of equipment operation and tasks [55]. The effectiveness of using AR tools in supporting decisionmaking and conveying the sophisticated knowledge to the parties engaged in construction has also been overtly advocated [54].…”

Whilst unavoidable, inspections, progress monitoring, and comparing asplanned with as-built conditions in construction projects do not readily add tangible intrinsic value to the end-users. In large-scale construction projects, the process of monitoring the implementation of every single part of buildings and reflecting them on the BIM models can become highly labour intensive and error-prone, due to the vast amount of data produced in the form of schedules, reports and photo logs. In order to address the mentioned methodological and technical gap, this paper presents a framework and a proof of concept prototype for on-demand automated simulation of construction projects, integrating some cutting edge IT solutions, namely image processing, machine learning, BIM and Virtual Reality. This study utilised the Unity game engine to integrate data from the original BIM models and the as-built images, which were processed via various computer vision techniques. These methods include object recognition and semantic segmentation for identifying different structural elements through supervised training in order to superimpose the real world images on the as-planned model. The proposed framework leads to an automated update of the 3D virtual environment with states of the construction site.

The development of a physical building control center can support project management and -control to optimize the flow of the complex processes at a construction site. The concept consists of equipping vehicles with sensors and using VR and AR-techniques to visualize this realtime information and allow an optical adaption to current circumstances. The result will be shown by a more efficient utilization and enhanced cost effectiveness. To analyse what is required you always start by clarifying the relevant object to be presented in VR. The instrument chosen was interview. The second step is to work out the necessary way of computing, viewing and manipulating this data. Finally a hardware setting is designed that would probably fulfill the derived requirements. The results of the interviews are presented. By processing these data the information and objects, which shall be visualized within the use case of a control center as well as in an on-site use case, are elaborated and also introduced. For these reasons hardware settings are analyzed and the basis for an implementation is established.

“…Research has identified several application areas in which colocated collaboration can benefit from Augmented Reality (AR) technology, e.g., collaborative geometric modeling [14] and collaborative construction simulations [13] (see Lukosch et al [18] for an overview). AR has also been suggested as a technology to create distributed augmented spaces to support building tasks such as those involved in collaborative design [31,32] and molecular modelling [7].…”

Augmented Reality (AR) displays have been suggested as shared-space technology to support remote collaboration, e.g., in design and building tasks. But with AR displays, the shared space typically consists of only the virtual work objects (e.g., design artifacts) while collaborators' interaction is grounded in their individual, physical environment. This can become problematic during activities that involve the positioning of virtual objects because the collaborators may require shared spatial references to coordinate their actions. In a lab experiment with 16 dyads, we studied how collaborators deal with that issue, and whether the provisioning of additive, virtual landmarks influences collaboration. As a result the landmarks improved user experience and decreased the reported temporal demand. In addition, we identified task-specific problem situations and provide implications for the design of distributed ARs to facilitate the collaborative positioning of virtual objects.
