Construction EDI in Australia some recent developments and current aims

Abstract: The construction industry in Australia covers a very large number o€ organisations from small suppliers and contractors to major consultants and government authorities. These are spread over a large geographical area and the works which they undertake range from very small to billions of dollars. There is a wide variation in technical sophistication within the industry. A 1992 survey of the use of electronic exchange of data between sections of the industry showed considerable interest, limited understanding, and little attempt at implementation. The current economic downturn and the long term return on the first costs involved, limits enthusiasm. Difficulties with its adoption and steps to overcome these are proposed with a timetable to the year 2OOO. This will be achieved only with government commitment, a well defined industry plan, and dose ties with the international EDFACT body of the United Nations.

Reverse propagation of data for building management

Abstract: Lifetime data for the management of buildings is becoming more feasible and is now expected by more facilities managers. It should be possible to extract the data related to the building fabric and systems from that generated during design and construction. For this to be just what the users require and in the form they require it, depends upon their involvement at an early stage of a project. Reverse propagation can then enable their wishes to influence the data collected so that redundant data is not produced and does not cause confusion. New forms of procurement such as partnering, allow this early involvement; alternatively there must be standards to define the general form of management data. In Denmark the CIS-CAD system defines a simple format being tested on a series of projects. It extracts information needed for statutory authorities and management, and examples are given based on continuing experience of its use. The principles of reverse propagation are discussed and the trend in databases to allow input from both ends of the process. This will eventually allow a more precise and economic definition of the building model and core data needed for management.

Gathering End-user and Stakeholder Information in BIM-based Infrastructure Projects

Abstract: Improving customer orientation has been identified as one of the major challenges in the AEC industry. A number of reports have highlighted the need for a change, greater efficiency and stronger client focus on the construction industry. Customer orientation refers to the idea that a project is only successful if it meets the needs of its intended end-users. This could only happen if customer and end-user information is connected with the project for its whole lifecycle. In the house building, where the customer is usually known beforehand, service-related tools has been developed to capture end-users needs in the different phases of the project. However, Infrastructure projects differ from house building projects in the several ways, for example, end-users are presenting a big audience and the ownership of the projects are typically public authorities. These characteristics, together with the basic features of the project management, makes difficult to exploit past experiences to the future projects. One of the major strengths in the building information modeling (BIM) is that it enhances collaboration between the team members and allows the mutual channel for information exchange. However, there is lack of knowledge how end-user and stakeholder information and requirements can utilize and gather in the systematic manner from the design phase to the maintenance phase and for the infrastructure life cycle. In a present, it is widely noted that research system in this area has been found tangled and ineffective. In this sense, BIM could be also an effective tool for gathering, storing and utilizing end-user requirements, information, and knowledge.

Virtual integrated design and construction

Abstract: "Construction projects involve a large number of both direct stakeholders (clients, professional teams, contractors, etc.) and indirect stakeholders (local authorities, residents, workers, etc.). Current methods of communicating building design information can lead to difficulties including : ? Client di-satisfaction, due to incomplete understanding of the planned construction and the length of the design and construction processes ; ? Functional inefficiencies of the completed facility which could have been designed out had the users been effectively involved in the design ; ? Re-work leading to waste of time and materials due to inaccurate initial work or clashes between components due to conflicting information. Recent surveys [e.g. Egan report, Design and Build Foundation report] show that significant value improvement and cost reduction can be gained by substantially integrated solutions being applied by project teams as a mean of reengineering the project process. In particular, their is considerable benefit to be gained by the integration of design and construction. Objectives The aim of this paper is to present the research carried out in the frame of the CAVALCADE (Collaborative Virtual Construction and Design) project, funded under the European ESPRIT programme HPCN domain. CAVALCADE’s goal was to develop a collaborative virtual prototyping system. Using a distributed architecture, the CAVALCADE system aims to support and enhance concurrent engineering practices therefore allowing teams based in different geographic locations to collaboratively design, test and validate shared virtual prototypes. Several industrial sectors were presented in the CAVALCADE consortium (construction industry, automotive industry, transport industry and aeronautical industry). Representatives of each of these sectors evaluated and reported on the use of CAVALCADE in their business. In this paper, the CAVALCADE system will be presented in details. Technical and organizational difficulties encountered during the project will be presented. Special emphasis will be put on the evaluations done for the participating industrial sectors and these evaluations will be compared to the specificities of the construction sector. As a conclusion, the objectives of new IST project DIVERCITY (Distributed Virtual Workspace for enhancing Communication within the Construction Industry) that will build, among others, on the results of CAVALCADE, will be presented and the modules to be developed (1. Client-briefing workspace, 2. Design review workspace, 3. Construction workspace) will be detailed. 1 CAVALCADE (Esprit project n°26285) started in January 1998. The project is to be finished by December 1999. 2 High Performance Computing and Networking 3 IST project n°13365 . The start date of the project is January 2000."

Common building model for administrative checking system against building design proposals

Abstract: Japanese local administrative authorities are running a joint project to develop a computer-oriented checking/confirmation system for lawfulness of building design proposals. They aim in the long run to establish a paper-less checking system which enables designers to efficiently utilize their project data derived directly from their own CAD systems. It will take much time to reach the goal, but this could be the first step to establish relating national CAD standards from which we are now kept away caused by specifically complicated characters of our AEC industry. This paper describes the outline of the system and explains briefly a proposed common building model based on standardized coding system as the results in the first stage of development.

Documents for the Contractor - StLB

Abstract: In the middle of 1960 the public authorities of the federal state of Nordrhein Westfalen in West Germany began to use data processing to produce documents, i.e. building descriptions for contractors. They started with existing sample building descriptions and soon realized, that these documents were nor suitable for data processing. A special committee the Joint Committee on Electronics in the Buildings Industry (Gemeinsamer Ausschuss Elektronik im Bauwesen, GAEB) was founded in 1966 to develop building descriptions, suitable for electronic data processing. The committee developed the StLB (Standard Library of Descriptions of Building Works) as a common language in the building industry. Similar developments could be observed in other German speaking countries such as Austria and Switzerland but also in Great Britain.
