<p>This thesis investigates the potential of Virtual Reality (VR) to solve established clashes in order to improve collaboration between industry professionals, while reducing spatial confusion. Industry professionals and academics state that it is collaboration itself that is one of the most critical factors in ensuring that a construction project is successful. In recent years people have investigated VR as a tool to provide a better environment for design due to its immersive properties and training potential. Current research is primarily focussed on the technology itself, but there are few studies conducted on the people using the technology and what they need in order to do so effectively. While it is essential to further the knowledge in the technological aspect, it is also vital to ensure that people can use it to its full potential. The aim of this study is to explore the relationship between advanced technology being developed and the way that people will be using it, alongside VR’s applicability as a collaborative tool for architecture and construction projects The focus of this study. While there are companies using VR in different stages of a project, it is unknown how productive people are when using this medium and what they require in order to use the technology effectively. Initial interviews with professionals have shown that there are problems in both peoples understanding of the technology used on projects as well as the methods of Building Information Modelling (BIM). The second part of this study involved multiple experiments in which users were put in different scenarios to solve clashes in a digital model using VR and Computer Assisted Design (CAD). This was performed in groups to investigate how they used the technology as well as how they collaborated within the digital environments. Initial experiments were run in Unity without a VR headset, and the final experiment was run using a VR headset (HTC Vive) for the full immersive experience. From these interviews and multiple experiments, the results produced insight into current user issues surrounding advanced BIM technology and the best way to implement them to make full use of the technologies capability during the design phase of a project. The results provided a framework detailing the information users need when using this technology to solve clashes collaboratively. Considering level of detail within the model alongside navigation tools, and perspectives provided a reliable method for aiding users in all aspects of collaborating in digital environments.</p>

A Company

This chapter presents an educational case study of applying Building Information Modeling (BIM) as an integrated design platform for interdisciplinary building and construction projects. The course is meant to focus on utilizing BIM for commercial construction. Students examine 3D geometry, spatial relationships, geographic information, quantities of materials, and properties of building components in this course. The students also learn the processes that make up BIM so they will be able to apply this information in a company. The purpose of the initial study was to assess the need for and receive feedback on the syllabus of the first commercial construction computer graphics course at Purdue University through a survey that was sent to industry professionals. The class was taught in the Fall 2009 semester and was successful according to the students in what they learned. The course was a 400 level course in which both upper level undergraduates and graduate students participated. The professor took the approach of a real world job and incorporated it into the content of the course. This chapter will discuss the initial case study of industrial professionals, the initial course creation, the development, and ultimately the final curriculum delivered within the course, as well as student feedback received at the end of the semester.

Building Information

Since its introduction, Building Information Modelling has evolved into a major technology in the construction industry, where information flows play a major role. However, the very presence of waste within these flows prevents the technology from reaching its full potential. This paper aims to develop a taxonomy focused on the sources of waste within information flows in BIM projects, as existing taxonomies focus primarily on work and material flows. Using a collaborative design science research approach, the study was divided into two phases: first, semi-structured interviews were used to collect data on BIM practices. The data was then used to identify similarities and contradictions in the information flows using process maps. Second, the ShareLab approach was used to validate the findings through a common agreement. The paper’s main contribution is the taxonomy of sources of waste in BIM project information flows, as it closes knowledge gaps in one of the main flows of construction projects. Another contribution is its use of a new approach to validate an artefact in a Design Science Research methodology named the ShareLab approach.

Point Of Reference

PurposeThe purpose of this paper is to present a modified model for collaboration in BIM-based construction networks (BbCNs). Though BIM is increasingly adopted and implemented across the construction industry, the problems associated with the lack of collaboration among teams in BbCNs remain a major hindrance to reaping the full potential of BIM. Previous studies have been conceptual in nature. This paper, therefore, attempts to modify and validate existing conceptual models that describe collaboration in BbCNs.Design/methodology/approachTo modify the conceptual model for collaboration in BbCNs, qualitative data through semi-structured interviews with BIM experts in the industry were collected and analysed using qualitative methods including the use of NVivo software.FindingsThe proposed model includes influential factors and their sub-factors to collaboration in BbCNs, as well as considering their indicators. Findings reveal that several overlooked concepts, particularly unfavourable BIM contractual arrangements, act as the root causes of the unwillingness of team members in BbCNs to engage in collaborative efforts.Research limitations/implicationsThe study's findings must be viewed in light of several limitations. First, the interviewees in this study were based in Australia hence their perceptions of BIM collaboration are reflective of the sociotechnical setting of BIM-enabled projects in this country. Also, the findings are based on the perception of experts in the field, rather than analysis of performance measures or quantitative assessment of associations among collaboration outcomes and various factors. This, however, provides the field with fertile grounds for future research.Practical implicationsThe study benefits researchers by shifting the collaboration discourse in BIM-enabled projects from technology-related issues to the people and contractual-related domains. Moreover, the developed qualitative model provides industry professionals with a point of reference to improve collaboration on BIM-enabled projects.Social implicationsThe study benefits researchers by shifting the collaboration discourse in BIM-enabled projects from technology-related issues to the people and contractual-related domains. Moreover, the developed qualitative model provides industry professionals with a point of reference to improve collaboration on BIM-enabled projects.Originality/valueArguments provided in this study highlight the necessity of considering the contractual arrangement of BIM-related projects and foster the willingness of team members to collaborate. This can be addressed using clear and comprehensive BIM execution plans and clearly explaining the role of BIM managers in the process.

The variants of the division of the life cycle of a construction object at the stages adopted in the territory of the Russian Federation, as well as in other countries are considered. Particular attention is paid to the exemplary work plan – "RIBA plan of work", used in England. A feature of this document is its applicability in the information modeling of construction projects (Building information Modeling – BIM). The article presents a structural and logical scheme of the life cycle of a building object and a list of works that are performed using information modeling technology at various stages of the life cycle of the building. The place of information models in the process of determining the service life of the building is shown. On the basis of the considered sources of information, promising directions for the development of the life cycle management system of the construction object (Life Cycle Management) and the development of the regulatory framework in order to improve the use of information modeling in construction are given.

Background: In view of many current mosquito-borne diseases there is a need for the design of novel repellents. Objective: The objective of this article is to review the results of the researches carried out by the authors in the computer-assisted design of novel mosquito repellents. Methods: Two methods in the computational design of repellents have been discussed: a) Quantitative Structure Activity Relationship (QSAR) studies from a set of repellents structurally related to DEET using computed mathematical descriptors, and b) Pharmacophore based modeling for design and discovery of novel repellent compounds including virtual screening of compound databases and synthesis of novel analogues. Results: Effective QSARs could be developed using mathematical structural descriptors. The pharmacophore based method is an effective tool for the discovery of new repellent molecules. Conclusion: Results reviewed in this article show that both QSAR and pharmacophore based methods can be used to design novel repellent molecules.
