Purpose This paper aims to focus on 11 digital technologies (i.e. building information modeling, artificial intelligence and machine learning, 3D scanning, sensors, robots/automation, digital twin, virtual reality, 3D printing, drones, cloud computing and self-driving vehicles) that are portrayed in future trend reports and hype curves. The study concentrates on the current usage and knowledge of digital technologies in the Swedish architecture, engineering and construction (AEC) industry to gain an insight in the possible expectations and future trajectory of these digital technologies. Design/methodology/approach The study applies an abductive approach which is based on three different types of methods. These methods are a literature and document study which focused on 11 digital technologies, two workshops with industry (13 participants) and an online survey (N = 84). Findings The paper contributes to a current state analysis of the Swedish AEC industry concerning digital technologies and discusses the trajectory of these technologies for the AEC industry. The paper identifies hype factors, in which the knowledge of a digital technology is related to its usage. From the hype factors, four zones that show different stages of digital technology usage and maturity in the industry are induced. Originality/value The contribution of the paper is twofold. The paper shows insight into opportunities, the current barriers, use and knowledge of digital technologies for the different actors in the AEC industry. Furthermore, the study shows that the AEC industry is behind the traditional Gartner hype curves and contributes with defining four zones for digital technologies for the Swedish AEC industry: confusion, excitement, experimentation and integration.

PurposeBuilding information modeling (BIM) is mostly limited to the design phase where two parallel processes exist, i.e. creating 2D-drawings and BIM. Towards the end of the design process, BIM becomes obsolete as focus shifts to producing static 2D-drawings, which leads to a lack of trust in BIM. In Scandinavia, a concept known as Total BIM has emerged, which is a novel “all-in” approach where BIM is the single source of information throughout the project. This paper's purpose is to investigate the overall concept and holistic approach of a Total BIM project to support implementation and strategy work connected to BIM.Design/methodology/approachQualitative data were collected through eight semi-structured interviews with digitalization leaders from the case study project. Findings were analyzed using a holistic framework to BIM implementation.FindingsThe Total BIM concept was contingent on the strong interdependences between commonly found isolated BIM uses. Four main success factors were identified, production-oriented BIM as the main contractual and legally binding construction document, cloud-based model management, user-friendly on-site mobile BIM software and strong leadership.Originality/valueA unique case is studied where BIM is used throughout all project phases as a single source of information and communication platform. No 2D paper drawings were used on-site and the Total BIM case study highlights the importance of a new digitalized construction process.

During the last decades, the introduction of Building Information Models (BIM) has opened new possibilities to ensure better communication and a shared understanding between stakeholders in construction projects. Similar benefits have been found in 4D simulations of the schedule. While BIM and 4D use has seen a steady increase, the potential benefits have not fully been realised, primarily due to tools not supporting and enabling the full potential of collaborative stakeholder involvement in scheduling. The benefits of 4D simulations come from improving communication between stakeholders. While traditional 4D modelling connects an existing BIM model with an existing schedule, a move from this type of passive 4D visualisation toward social co-creation enables all stakeholders to be involved in the scheduling process. This connection is further enhanced with the use of Virtual Reality (VR). Recent research has shown VR to enhance understanding and perception of the space and details and, thus, a better understanding of the project. This paper maps collaborative planning and scheduling method and traditional 4D scheduling using process modelling. This mapping is followed by implementing the 4D collaborative planning and scheduling method in the virtual project planning system with support for a multi-user interactive VR environment. The system enables social co-creation both during the planning and scheduling and during 4D modelling; it improves understanding of the project and the planning and scheduling.

During the design of a new hospital it is necessary for all involved stakeholders to understand, participate, communicate, and collaborate with each other to obtain a high-quality outcome. In order to support these creative and shared design processes, this paper presents the design and evaluation of Virtual Collaborative Design Environment (ViCoDE)a new collaborative design system. ViCoDE features seamless integration of a multi-touch table and several immersive VR-systems that facilitates interactive and collaborative design work with immediate feedback. The system has been evaluated during two collaborative design workshops in a real-life context of designing new healthcare environments. The results show that the multi-touch table and VR-system complement each other very well by facilitating different design spacesboth collaborative, as well as individualand that it fosters better understanding, participation, communication, knowledge sharing and collaboration among the different stakeholders. The contribution is two folded: presentation of new a collaborative design system and the evaluation of the use of it in a real-life design context, which demonstrate how these new technology-based workshops may facilitate design management.
