  1. 1. Virtual reality in construction : tools, methods and processes

    Författare :Stefan Woksepp; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : Present-day construction projects are characterized by short-term partnerships between multidisciplinary teams with varying levels of process maturity and information handling capability. They involve the planning, design and erection of structures of all types. LÄS MER

  3. 2. Virtual Collaborative Design Environment: Information structure and interfaces

    Författare :Shahin Sateei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cross-project learning; Collaborative Virtual Environment CVE ; Design Guidelines; virtual reality; Head-mounted display HMD ; User involvement;

    Sammanfattning : The failure to identify design issues in early phases of construction projects has been identified as a significant cause of costly rework, as these issues can impact the building occupants’ abilities to efficiently perform their daily work tasks. Therefore, it is crucial to consider their feedback when design reviewing. LÄS MER

  4. 3. Managing virtual factory artifacts in extended product lifecycle management systems

    Författare :Iman Morshedzadeh; Amos H. C. Ng; Masood Fathi; Kaveh Amouzgar; Dag Henrik Bergsjö; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Virtual models; product lifecycle management; information model; knowledge management; ontology; manufacturing data; provenance; manufacturing systems; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : Reusing previously designed virtual models and the knowledge extracted from running them can reduce time and costs. Since these models are representations of physical artifacts, they have been built based on some criteria, assumptions, and limitations. LÄS MER

  5. 4. A process model for work-flow management in construction

    Författare :Rogier Jongeling; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggproduktion; Construction Engineering and Management;

    Sammanfattning : This thesis describes a novel approach for management of work-flow in construction, based on the combination of location-based scheduling and modelling with 4D CAD. Construction planners need to carefully design a process that ensures a continuous and reliable flow of resources through different locations in a project. LÄS MER

  7. 5. A Virtual Design Studio for Low-Frequency Sound from Walking in Lightweight Buildings

    Författare :Nata Amiryarahmadi; Sweden Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight floors; Walking sound; Low frequency; Annoyance; Virtual design studio;

    Sammanfattning : In recent years there has been a growing interest for building lightweight multistorey woodenresidential buildings in countries like Sweden with large and renewable forests. While positive aspectsof these buildings, such as sustainability, ease of construction and lightness, motivate building more inwood, poor acoustic performance is a risk which concerns the wooden-building industry.
