Product modeling strategies for today and the future

Abstract: Today, there is a growing set of technologies being developed for information exchange in the construction industry. These range from Aspect Models in specific product areas to large scale integrated product models, to new languages such as EXPRESS-X and EXPRESS-2. The purpose of this paper is to sort out and review these various efforts, from several different perspectives: * in terms of what can be used now or in the near future in a production form; * in terms of the significant technical issues and limitations that may require generation changes in exchange technologies; * in terms of external business practices (reflecting case studies), practical benchmarks and adoption criteria, political and other externalities that are affecting these efforts. The survey will review the following issues: * current capabilities of ISO-STEP Part definitions to support information exchange in the building industry; * current efforts by IAI, BCCM in STEP, and other parallel activities and their potential contribution and pitfalls (problems to be overcome); * different current research efforts and the problems and solutions they identify, including COMBINE, EDM-2, VEGA, work at CIFE at Stanford University. Hitherto underdeveloped model aspects, such as capturing the semantics of the client's brief, or capturing design evolution (program, decisions and rationale), modeling performance assessments, and others such as relevant standards, construction site handling, etceteras will be reviewed and priorities assessed. Over the last ten years, the set of requirements that a building product model must meet in order to be accepted in practice as a significant 'productivity enhancement has incrementally expanded. That is, as various research goals have been set, then met, the true extent of the challenge for realizing production-based building product modeling has grown. We will review this expanding set of requirements and attempt to scope their final range. These requirements include, among other aspects: * 'semantic coverage', * level of interoperability across applications, * level of embedded project management control, and * maintained linkages to parallel 'unstructured' information flows, e.g. managed by Engineering Data Management and Document Management software. It will be argued that a viable growth scenario regarding the semantic coverage of building models is likely to be a determining factor in the way that CAD vendors will embrace these as the basis for developing the next generation of architectural CAD software. Priorities of development will be identified and compared with perceived market pulls. The perspective taken will emphasize the US point of view. However, we will endeavor to also weight significantly the European situation and efforts. The result of these perspectives will be to identify 2-3 scenarios of future evolution in the area of building product modeling, with an assessment of their likelihood of coming to be, and the critical issues needed to accomplish them.

The Influence of Space Layout Design on OccupantÕs Energy Behaviour

Abstract: In the past 15 years, the calculation of energy consumption in buildings has become more and more critical due to growing scientific and political concerns to respond to the challenges of global warming and climate change. The estimation of energy demand in buildings is now often a required process during the design stages. Yet, there is a considerable discrepancy between the predicted and actual energy consumption in buildings due to occupantsÕ energy consumption activities. OccupantsÕ presence and their interactions with building systems play a significant role in buildingÕs energy consumption; however, it has been overlooked in building energy predictions. Different studies have been performed with the aim to better understand the parameters affecting occupantÕs energy behaviour with special focus on climatic, economics, regulations and social/personal aspects. Interior design of the space, too, has various impacts on behaviours of occupants and their interactions with building systems which affects the energy consumption of buildings. Space layout is a feature within interior design of space which influences occupantsÕ movement and choices of intentional behaviours. This paper highlights a gap in the knowledge by introducing Òspace layoutÓ features as an influential factor on occupantÕs energy behaviours and propose an analytical method to study the impact of the space layout on occupantsÕ energy behaviours. Understanding the impact will help designers influence the sustainable behaviour through the design of interior spaces.

World wide web as a coordination technology for knowledge work

Abstract: This paper will bring some understanding of the World Wide Web as an information and coordination technology, and suggest some principles and metaphors for Web working. The suggestions will be underpinned by recent experiences from a collective Web-working project, and a transformation of a technical standard into hypertext format. Some ideas and visions for future developments based on the new medium are presented. World Wide Web is more than a tool or a technology, it is a new medium based on a set of very simple principles that enable us to cope with a vast Ocean of information and knowledge. The basics of World Wide Web and HTML (Hypertext Markup Language) will be explained. A small-scale experiment in collective writing in Web will be reported. The task was development of the PAKT Yearbook of 1994, where a dozen of contributors worked concurrently on individual pieces around a shared Yearbook structure. This small project may in some sense resemble an engineering project, where many discipline experts are performing individual tasks around a shared goal and work breakdown structure. The experiment was based on use of Microsoft Internet Assistant which provides a simple add-on that makes Microsoft Word a combined Web reader and writer. Using this interface to the Web, working there is as simple as traditional word-processing. This mode of working can easily be expanded with any kind of tool based on the same concepts of process linking. There is, however, no support for the work processes associated with creating the product (in our case a Yearbook), or the organization of the processes. Based on our experiences, we suggest some metaphors and practical approaches to efficient Web working. Another experiment has been in the domain of technical standards. A couple of existing, paper- based standards from the petroleum industry have been converted to HTML, with cross-references transferred to active hyper-links. Using WWW as a one-way information server and as a shared working space will be illustrated. We see at least three future aspects of Web development; active objects replace static information, information structures will be supplemented by knowledge processes (enterprise modelling), and the information economy will evolve based on integrated flow of transactions.

Customer relationships management in AEC sector

Abstract: Quality is the major guide for enterprises in terms of competitive strength of organizations in the information age. While globalization increases its impact throughout the world, the term “Quality” expands its meaning and the cultural and social aspects of quality becomes the most important contributors of the product quality. The customer orientation of the finished product and after sales service is becoming vital in terms of marketing. Industrialized sectors had been providing solutions in that sense under the Total Quality Management (TQM) principles since the early 80’s. For the Architecture/Engineering/Construction (AEC) sector, several managerial tools and techniques has been adapted but these partial solutions do not perform well enough as they did success in other industrialized sectors. This is probably because the need for an enterprise-wide customer orientation infrastructure is not yet proposed. This paper discusses the early concepts about a “Customer Relationships Management” (CRM) model for the AEC sector which, CRM to be the foundation for TQM; issuing that CRM is the key enabler for any tool or technique towards quality and industrialization. .

User survey on a wan portfolio M.I.S. used for porfolio/project management in Hong Kong.

Abstract: This paper presents the results of recent research into the user expectations for a Management_Information_System (MIS) for the project/portfolio-managed delivery of a large and diverse range of projects. In 1998, the Works Bureau of the Government of Hong Kong undertook objective measurement of the extent that an MIS, called the PW_MS, contributed to the successful project and portfolio management of its large and diverse portfolio of more than two thousand public works projects. This rolling-programme of projects includes up to 72 types of public infrastructure. The delivery process depends on a highly differentiated organisation in which each of the public works departments has different staffing levels, workloads, locations, and each undertake different types of work. The objective of the assessment was to determine: · the extent that the PW_MS was successfully used for the management of individual projects; · the extent that the PW_MS was successfully used to help manage the portfolios-of-projects overall; · the extent that other means of data collection and reporting that are otherwise used for both of these functions; and, · to identify the requirements for an improved MIS. This paper presents the results of this postal survey of a population of five hundred and eighty-four authorised users of the PW_MS. It is a complex WAN system, with 168 terminals in the client and public works offices for operational access to the MIS. It has routines for the planning, reporting and monitoring of the cost, time and scope aspects of each project in the PWP. It establishes a fixed plan for each project and provides an audit trail of progress towards completion. The data in the system is combined to provide summary reports of portfolios of projects. A random selection from the User-population was used to form a population-sample for the postal questionnaire survey. The sample frame was constrained to ensure a 95% confidence limit that the response was statistically indicative of the population; and that it included sufficient numbers of the primary classes of users to also ensure a 95% confidence limit that the response was indicative of these strata of the population. This methodology is described in the paper. A sixty-five percent response was achieved. The results show that the User satisfaction with the PW_MS is not high. The results state a range of User dissatisfactions but they do not call for a fundamental change in approach: they validate the exploitation of proven, readily available, information technology for the management of portfolio-of-projects. Portfolio-management and project management is enabled by these techniques although the survey results indicate that more can be done to improve the man-machine interface. The results identify key-areas for such improvement. These findings are presented in the paper.

Longitudinal-grounded case study of a project management information system: a reality check.

Abstract: This paper presents the methodology and findings of a longitudinal-grounded case study of the ambitious implementation of a PMIS within the public works organization of the HKG SAR. It has provided an opportunity for practical experimentation through the quantitative measurement of 'before' and 'after' effects arising from a change in management techniques. These were substantially dependent upon the introduction of a novel PMIS that conformed to the Cleland and King model for a portfolio-management-system that is added-value gained from a project-management data pipeline. The timing of the implementation and its attributes makes it an appropriate vehicle for experimentation to substantiate the Cleland and King proposition for project and portfolio management in multi-projects scenarios. A triangulated-search of the case files covering all aspects of the implementation of the PMIS provides a reality check of the construction business issues that drive systems implementation. It leads to the observation that empirical research into the day-to-day reality of IT innovation within the industry is essential if the gap between research and practice is to be narrowed. Pre and post implementation measurements of performance are used to assess the results achieved from this example of in-practice innovation. At least a three-fold improvement in spending performance was achieved when five years post implementation performance was compared to the five-year pre-implementation period.

The use of ICT in the construction industry: critical success factors and strategic relationships in temporary project organisations

Abstract: This paper describes the application of a previously developed model of critical success factors for ICT-mediated chains to three construction project supply chains. These cases drew on the experiences of key stakeholder organisations within each in order to firstly, identify the extent to which features of a previously developed, generalised model of ICT success factors were present in each case, and secondly to extend the model in respect of those aspects relating to pre-existing relationships, strategic relationship formation, and the expectation of a continuing business relationship into the future. The paper is structured to describe the protocols and analysis used, and to report a summary of the findings across the three cases.

A WWW-based regulation broker

Abstract: There is an ever growing body of regulations covering many aspects of design, operation and disposal of engineered systems, artifacts and products. Constructed facilities are governed by an exceptionally large number of applicable regulations. We have developed a WWW–based broker for providing access and support for using these regulations. In this paper, we describe the underlying representations of the documents and classification systems, the search engine used, and the basic operations conducted by the broker. We also discuss further work we intend to conduct.

From BIM Models to Integrated Energy Efficiency Applications for Industrial Facilities

Abstract: Raised interest in efficient use of available resources in industrial facilities prompts for software-tools to predict and manage energy demand of the whole system. An integrated approach considering all energy consumption contributors, classified into building, energy system, production and logistics, is developed within the research project Balanced Manufacturing (BaMa). Thereby BIM models of industrial spaces containing valuable information are used for creating a comprehensive representation of building-related aspects in a hybrid simulation environment, able to assess manufacturing and auxiliary energy demands.For testing the applicability of this integrated hybrid approach, a prototype is developed based on an actual use case. The simplification procedure is presented and the energy performance results are compared with that of an established building energy modelling software, discussing advantages and limitations. Essential information that needs to be transferred from the BIM model is clarified and prioritised.
