Abstract [en]

Well detailed, informative and accurate work instructions are a necessity to mitigate delays in construction. Today, this is done through a combination of shop drawings, documents, sheets, work pre-planning meetings and onsite verbal work instructions to transfer knowledge and information between all actors. Due to the subjectivity of these methods, many incorrect assumptions and man-made errors originated from miscommunication and misinterpretation can occur. Such issues are tough to identify prior to their occurrence on construction sites, leading to construction delays. Virtual Reality (VR) technology can simulate and visualize assembly processes using Standard Operating Procedure (SOP). The visualization aims to ensure a quality communication with skilled workers and to aid their interpretation of SOPs by reducing assumptions. As a result of a more effective education, it can support the collaboration between actors. Utilization of SOPs for visualization of Work Instructions (WI) and assembly processes are important, because many process WIs on construction sites are repetitive. Modularity can increase the efficiency by supporting instancing and variation creation of construction tasks and products. Interactivity can support the continuously changing status and demands of construction sites. A method has been iteratively developed to support visualization of modular and interactive SOPs within the context of industrialized house-building (IHB), to increase the quality and consistency of communication at construction sites. Concurrently to development of the method, a prototype using VR technology was developed. Interactive functionalities along with VR technology make it possible to adjust SOP and WI modules to suit the demands and conditions of the construction site, including real-time. As a result, the developed method is responsive and adjustable to conditions such as weather, man-made errors, assembly re-sequencing and re-scheduling. Combining product design, SOPs, WIs and assembly process in early stages of construction has shown to help identify potential issues and aid in planning for cautious measurements. Results show that by using the developed method, skilled workers were able to identify occurring miscommunications, and misinterpretations between them, site managers and foremen as well as ensuring their understanding.

Abstract [en]

The house-building industry is increasingly recognizing the importance of information, viewing it as key for driving sustainable construction. This acknowledgment highlights that informed decision-making, based on the effective use of information, can enhance all phases of house-building. Sustainable house-building demands an integration of diverse information, technologies, and standards, necessitating the increased use of information to support decision-making. In response, the industry is focusing more on the capture, management, and storage of information. Despite significant investments in these areas, the full potential of this information is not yet realized due to the lack of and poor use of structured information systems. Furthermore, the information produced is often tailored for specific segments, leading to the creation of information silos that isolate data, making it difficult to collaborate across different stakeholder groups. While the benefits of structured information are widely acknowledged, the integration of structured data and information technologies in house building is impeded by unintuitive and fragmented information management practices. Additionally, many current information systems in the industry still emulate paper-based document structures, continuing the use of unstructured and non-standardized data. To address these challenges, this thesis explores the development of information structures that facilitate reusability across house-building projects and explores the integration of visualization techniques into these development methodologies. By employing cross-case analysis as the scientific method, this study evaluates findings from multiple cases to identify common themes and patterns, thereby enhancing the understanding of the observed phenomena by effectively comparing and contrasting findings from individual case studies.

The findings of this thesis underscores the delicate balance required in information structures to effectively blend standardization with project-specific flexibility. Effective reuse in house-building necessitates an equilibrium between these approaches to achieve both widespread applicability and project-specific relevance. The case studies analyzed illustrate how navigating this balance can enhance communication, foster collaboration, and ensure adherence to established procedures. This balance is crucial because information visualization can falter when skewed too far towards either extreme of this spectrum. Over-standardization can hinder the application to specific project nuances, while excessive customization may complicate data collection and visualization, requiring substantial resources to format and prepare. Therefore, developing reusable information structures depends on achieving a middle ground that is neither overly standardized nor excessively tailored.
