Big Data Applications in Built Environment: Towards a Use Foundation Model

Abstract: The term ‘big data’ is increasingly permeating the current debate over the present and the future of our built environment. There are heightened expectations about the role big data may or can play in enabling new applications and decisions across the whole lifecycle of assets, from early design phase through construction to operation and end-of-life. It is therefore necessary to analyse the state-of-the-art in big data applications in built environment. This paper presents a structured and systematic literature review on this emerging theme. The results are quantitatively analysed using network and clustering techniques. The research identified distinct clusters within two lenses: (1) the project lifecycle (i.e., design/planning, construction, and operation), and (2) the built environment hierarchy scale (i.e., component/product, building/facility, site, neighbourhood, region and city). Six clusters of big data applications across the two lenses were identified: energy management, traffic management, design & planning, onsite construction activities, city-wide services, and smart cities.The clusters show the level of research intensity around each of their nodes and the connections between the nodes which indicate the emergence of new avenues of investigations. These results represent the first steps towards developing a descriptive ‘Use Foundation model' for big data applications in built environment.

Structural framework for assessment of fac-tors influencing the serviceability of facilities

Abstract: Assessment and control require a gauge or a scale to relate processes to results in order to evaluate the strategies adopted and to enable effective variations to be made. Assessment is a requisite to effective and efficient management. A firm needs to be able to gauge the immediate and a future impact of its decisions and strategies. Assessment is needed to enable structural adjustments to a business whenever it is expedient. Both long term and short term assessment should encompass all aspects of activities in a firm. This means that the facilities needed to implement the strategies should be considered along with the traditional functions of management. The assessment framework considers many factors including selecting the right qualities to assess and also making the assessment right. A good classification and structuring of the source information is needed to give a total picture of facilities and hence enable an effective management brought about by total control of the situation. This study examines and models factors that define suitability and viability of facilities and proposes an assessment framework. It is envisaged that the results of this study will enable a better understanding of facilities management and its related use as a tool towards the bigger goal of portfolio management.

A geographically distributed multi-reasoning mechanism for change negotiation management of large scale engineering systems

Abstract: In large scale engineering projects, no design process can perfectly forecast every aspect of detailed project conditions. Sometimes oversights, mistakes or changes in the design must be corrected, and sometimes completely external factors also force changes in the situation. The basis for most changes is some form of conflict. In addition, the negotiation of such conflicts frequently results in suboptimal, inefficient agreements leading negotiators to believe that they could have reached other settlements.This paper presents the preliminary results of a research that explores mechanisms to provide a model for this negotiation process and applies automated multi- reasoning and learning mechanisms to the same. The ultimate goal of this research is to provide negotiators with precedence information to help them reason in a co-operative way assisting in the effort to seek "all-gain" rather than "win-lose" solutions.

STEP software architectures for the integration of knowledge based system

Abstract: ATLAS (EP 7280) is a collaborative research project to improve the competitiveness of European Large Scale Engineering companies within the world market. The project focuses on the development of software Architectures and Tools based on non proprietary information exchange standards such as STEP and EDlFACT to improve business integration and co-ordination. The understanding of software integration does not only cover classical engineering applications but also addresses knowledge based systems (i.e. rule based and case based) by means of STEP based AI environments including a LISP binding of the SDAI specification (STEP Part 22). The work undertaken during the course of the project opens the road to the future integration of KB systems within STEP architectures.

Advanced electronic document management solutions for the construction industry: the CONDOR project

Abstract: The paper is based on research carried out within the CONDOR project funded under the European ESPRIT programme. CONDOR is specifically concerned with defining the working practices, processes, techniques, tools and technical infrastructure to allow the construction industry to progress from its current position towards a large scale, computer integrated industry. Furthermore, the project aims at bridging the gap between current information systems and future ones, and provides a migration path from document-based to model-based approaches to information representation and structuring. After a brief overview of the state of the art of Electronic Document Management systems in the construction industry, the paper presents the overall CONDOR system architecture, along with a detailed description of its components. The latter include: * the CONDOR Integration Services (implemented as a class library in the CONDOR demonstrator); * the CONDOR API: it defines the services to allow on the one hand, inter-working between the projectís legacy EDM systems, and on the other, semantic linking between different documents and between documents and other information objects (the precise services that are provided have been largely determined from the results of the analysis conducted by the projectís end-users), * the Adaptors: they provide the mapping between the CONDOR API and each of the document and object management systems to be integrated. It is worth pointing out that the CONDOR system is designed to be open enough to coexist and inter-operate with construction legacy applications, as with other existing and emerging distributed components, in a seamless way. These legacy applications can then, in turn, take advantage of the generic, and construction specific, advanced document management functionality developed within the CONDOR project. The paper then presents the conceptual models that support the CONDOR system, this includes the CONDOR Information Management Model (CIMM). The CIMM is concerned with the management of information produced within a projectís lifecycle, from inception to demolition. Whilst the CIMM is developed within the frame of the construction industry, it is aimed to be generic enough to be used in any other industrial context. CONDOR addresses four primary issues that are central to information management: ownership, rights and responsibilities; versioning of information; schema evolution ; and recording of intent behind decisions leading to information. Finally, the paper presents one of the project end-userís implementation strategy of the Condor approach. The CONDOR project is ongoing and supported by a user interest group, which involves representatives from a variety of non-construction industry companies all over Europe.

Large Scale Calibration for Augmented Reality on Construction Sites

Abstract: Accurate calibration methods are a key to achieve accurate registration in AR systems. Most calibrations developed thus far represent the system accuracy as pixel errors regardless of the view distance. Examination of work tasks in construction, however, indicates that the system accuracy may not satisfy the accuracy demands of specific work tasks due to variations in the view distance. This indicates the necessity of large scale calibration for construction sites for seeing objects at longer ranges with satisfactory system accuracy. This paper proposes a new scheme for large scale AR calibration for construction sites.

Presentation of design models

Abstract: CAD systems offer new and improved techniques for the presentation of designs. This paper presents several of these techniques that are based upon computer-generated images of a 3-dimensional computer model of a design. These new techniques include holography, animating and virtual reality. Some of the techniques that can be improved by CAD systems are paper scale modeling and stereoscopy. - presentation purposes, such as showing a design or explaining functional or - presentation activities, such as modeling a design or generating images; - presentation techniques, as mentioned above. techniques employed and the production activities. Because production activities can be very time consuming, the purpose of the presentation and the preferred techniques should normally be well specified at the beginning of a presentation production to makethe latter creative productive. However, since most of the computer-based presentation techniques are still new to most designers, it will be very difficult to make the right specifications of purpose, techniques and activities at the beginning of the production process. That means that there is a need for a better understanding of the techniques and for a more flexible way of producing presentations of designs. Calibre has developed tools to make the production of presentations more flexible. One of the tools is a program (ModelCom) that converts different 3-dimensional computer models of designs (design models) into models for different programs that are able to generate images. Another tool is a program (ImageCom) for converting different generated images into image descriptions for different presentation techniques. These tools are of great importance for Calibre's exploration of various techniques for the presentation of design models. This exploration gives Calibre the unique opportunity to present a varied menu of presentation techniques and related future expectations. The paper describes: technical aspects; There exists a relationship between the purpose of a presentation, the presentation
