Information model for construction briefing

Abstract: This paper describes an information model for the establishment and processing of client requirements on construction projects (briefing). The model is described using the EXPRESS-G graphical notation, and it provides a formal representation of the nature, sources and interrelationships between information required for the implementation of a methodology for client requirements processing in a computer environment. The rationale and details of the methodology, which forms the basis for the information model, are reviewed, and the complete entity-level diagram of the EXPRESS-G model is presented and discussed. The implementation of the information model in a computer environment will enhance the definition, analysis and translation of client requirements into solution-neutral design specifications. This in turn increases the chances that the resulting facility that is designed and built from those requirements will be to the satisfaction of the client.

Keywords: construction briefing, client requirements, information model, EXPRESS-G notation

Integrated design of an automation system to solve cost estimation problems in design phase

Abstract: "Architectural offices have a complex nature due to the large number of participants that are involved in the design process although they are considered simple organizations. One of the basic project-based problems that architects encounter in design process is to keep the construction costs under the limit given by the customers of the projects and to enlighten the customers about the impacts of their decisions on building costs. Calculation of the impacts of alternative decisions on building costs must be a continuous activity during the design stage and the models developed for the architectural practices should also provide this kind of tools for the architects. Although some of the CAD based software provide this facility, they have limitations. As for the commercial software packages for architectural practices, they were designed mostly in an accounting oriented approach and do not provide cost estimation facilities. This paper presents the integrated design of a computer based office automation system, ASAP (Automation System for Architectural Practices), a model for architectural offices that was developed by considering the lacks of currently available office automation models and the cost estimation system (ASAP-CE) that can be integrated or works independently to expose the estimated costs of alternative solutions for building design."

Automated sustainability compliance checking process: proof of concept

Abstract: Building Information Modelling solutions are evolving to achieve effective integration in the construction industry. The emerging approaches of knowledge sharing and data processing push the researchers to re-engineer innovative automated processes for integrated 3D design that complies with regulations and statutory requirements. This paper presents a generic approach for automating BIM compliance checking with standards and best practice with a focus on sustainability related standards. A methodology will be presented to provide a reusable solution for compliance checking within a similar context. The proposed approach is generic in nature thus allowing implementation in different fields of engineering including electrical engineering, energy, water and electronic engineering. It is anticipated that the findings of this research will promote a fundamentally innovative BIM-based compliance checking for a variety of industry standards. In this approach, the RASE methodology is utilised to extract requirements from sustainability based regulations, with the goal of converting them into compiled coded rules for execution by a rule engine

Application of fuzzy linear programming in construction projects

Abstract: In classical optimization model, the objective function and the constraints are represented very precisely under certainty. However, many of the constraints are externally controlled and the variations cannot be predicted to a reliable extent. This may cause difficulties in representing these interacting variables for optimization. To overcome these limitations, Zimmerman's fuzzy logic approach is applied for optimization in this paper. Here, the embedding simulation results are used as inputs to a fuzzy linear programming model to soften the notion of "constraints" and "objective function." This approach will acknowledge and postulate that the objective function and the constraints are of the same nature and the distinction between them is gradual rather than abrupt. An application of this integrated approach to a case study demonstrates the efficacy of this flexible algorithm in dealing with qualitative factors in a more meaningful way than classical linear programming. One of the main advantages of this method is that it can be easily implemented in the existing computer programs for optimization.

Construction competitiveness and knowledge management. Basic considerations

Abstract: Based on the importance of the construction, stakeholders in this industry should support its competitiveness improvement. However, authors sustain that not all are sufficiently informed about the current challenges, problems and advances regarding this industry and by this reason many valuable knowledge get lost. Understand the existence of different realities about construction, the shortages of information and state of the art is crucial to propose and implement strategies to support practical solutions. As a part of an on-going investigation, this research includes the revision of the nature, significance and challenges faced by the construction and makes reference to competitive policies, lessons learned and sustainable construction while knowledge management is emphasized as a key element to sustain construction competitiveness. Based on documental revision and field work developed with participation of oil and petrochemical construction companies and construction experts, this research present some preliminary results that confirm that there is a breach between construction knowledge available and the construction problems faced by this industry. This evidences that even of the practical knowledge available for the understanding of construction problems, to identify enhancement opportunities and to improve the complex processes related to construction, there is an important recurrence of diverse construction problems both in developed and developing countries. Based on such findings authors sustain that additional efforts must be devoted to permit that the existing knowledge transcend theory and can be used by construction organizations to improve it performance and competitiveness thus contributing to the solution of practical problems for the benefit of society. The presentation of basic information about those issues in practical way in diverse situations and with empirical evidences may facilitate the end-users change of attitude in front of such resources and thus reduce the existing gap between knowledges and construction problems.

PROCESS ORIENTED INFORMATION MANAGEMENT IN CONSTRUCTION

Abstract: The construction industry is often accused of being fragmented and inefficient in nature due to the lack of continuity and repetitive behaviour in projects. For many years information technology has been put forward as a solution. But, despite the potentials, little gains have been harvested by the development of computerised information systems (IS). The overall aim of this research is to determine if a more accessible and clearly described housing development process could be enabled by an information system, which in itself, could improve both individual and project (group) performance. Two research questions are being put forward; first, will a process-oriented IS positively impact on the performance of project managers and in particular on the performance of project groups? Second, how important is a process-oriented information management process for the success of the IS? To answer these questions an action research approach with large influences of survey research has been adopted. The research consists of two phases; a process orientation within a large Swedish housing development company and a survey of project managersˇ¦ attitudes towards a new process-oriented IS also including a study of dependencies found among variables of information system success (ISS). To enable a verification of the success of the IS an assessment instrument - hypothesis model - for evaluating ISS was developed. The assessment instrument was built on DeLone and McLean's (1992) ISS model and extended to include measures of information management process quality (process quality). The hypothesis model was then tested empirically with a questionnaire survey. A statistical test was also performed to test the hypothesised relationships of the augmented ISS model. In summarising the findings of the data analysis, it is evident that the new IS received unexpected support from the respondents. The findings also indicate that the collected and analysed data show support for numerous of the hypothesised relationships of ISS. Conclusions are drawn that confirm the presence of a process quality measure for assessing ISS. From a practitioner's perspective, this research suggests a course of action for process oriented organisational development. It also indicates beneficiary use of a process focus in IS development.

The architect's database

Abstract: Architectural design deals with issues of widely varying nature: aesthetical and spatial issues, detailing, material choice and systems design, having a strong impact on the cost of operation, repair and maintenance. Information technology in construction industry provides new possibilities of reusing design solutions thus supporting some aspects of the design process. The main purpose of our project is to investigate methods for structuring the information related to architectural work in order to support the process of reusing design solutions. An equally important task is the development of a concrete application of a comprehensive archive of components in an object-oriented relational database. The basics of the architectural work are shortly discussed and an outline of a database called a Kit of design parts is presented. Also, a comment on multimedia as a way of integrating the various kinds of information needed in an architect's database is made. Finally, the conclusion is drawn that informution technology will be one of the most important challenges facing the architect's profession during the years to come. Nevertheless tools like the Kit of d. p . will become vital tools that will help the professional to fulfil the new requirements.

An investigation into the main information dimensions of corporate real estate management

Abstract: The fragmentation of the construction and real estate sectors, and the information intensive character of their activities, makes it very difficult to select, store and transfer relevant information among its members. The volume and diversity of data in these sectors have been a hindrance for developing effective, integrated and standardised information systems for construction, building and real estate management. To overcome these problems at the level of strategic management of corporate real estate, a research was set to elicit the main information dimensions, or the main concerns, within the area. This research used as paradigms models that succeeded on defining and using the main dimensions of a particular subject matter, facilitating communications, decision-support and learning processes. Examples of these paradigms are the main factors of production in the theory of capital in economics, the balanced scorecard and the critical success factors in organisational management, the three dimensions in project management and Pena's (1987) main concerns for programming in architecture. The research consisted of a content analysis of seventy corporate real estate management (CREM) models used in industry and academia eliciting the main features (concepts, tools, techniques, methods) quoted on these models. Using classification techniques and supported by a literature review and expert interviews, these features were classified according to their nature, similarities and origin. The main dimensions resulting from this classification system provided the main information dimensions in CREM. These dimensions are financial, physical and human, each one divided in three classes, respectively. The financial dimension is divided in the classes rentability, business information and intelligence. The physical dimension is divided in the classes data, management and diagnosis. Finally, the human dimension is divided in the classes organisation, occupancy and customer. Examples of uses of the CREM framework are given.

Supply Chain Capital in Construction Industry: A Conceptual Model

Abstract: Supply chain management is one of the concepts adopted from other industries and being translated to suit the construction industry in order to bring improvements within the industry. The recent emphasis is on the integration of the whole supply chain because of the fragmented nature of the industry, and the large number of participants involved in a project development process. One of the aspects to achieve integration is by managing both tacit and explicit knowledge existed within a project supply chain through IT systems and social interaction. The main purpose of this paper is to develop a conceptual model, that provides a link between construction organisations and their learning activities as part of a supply chain of a project, resulting in creation of a learning organisation and a learning supply chain. The model shows that the learning supply chains, consist of learning organisations which would create supply chain capital in order to promote innovation and creativity by managing knowledge in supply chains on long term basis. In addition, the learning organisations would also establish a virtual knowledge transfer among themselves and the supply chains they are involved. The paper also suggests that, as unit of competition changes from organisation verses organisation to chain verses chain under supply chain management, supply chain capital will become increasingly important for sustaining competition within construction industry. Therefore, supply chain capitals are to be created through managing knowledge in supply chains on long term basis using the proposed conceptual model. The model also facilitates innovation and creativity essentially required to thrive in the downturn business environment of today in many countries in different parts of the world.
