Design in a hypertext environment

Abstract: In the paper it is suggested that hypertext is suitable for the development of design tools associated with the preliminary design phase of Building Services Enginnering. This argument is supported by the development of a prototype model for "sprinkler installation design". The Macintosh HyperCard has been chosen to demonstrate the effectiveness of the procedures.

Building codes and performance standards as knowledge-bases for design

Abstract: Code compliance checking is an integral part of the building design process. Many research attempts have been made to automate code compliance checking as a secondary task to developing a design solution.But it is possible to represent the code requirements in a knowledge base to assist in the design process. In the present study, a buildingenvelope design knowledge base has been developed to model the performance based design approach. The National Building Code of Canada's design requirements and an ASHRAE standard specifications for building envelope are incorporated in a knowledge base. A frame-based knowledge representation technique is used to implement the semantic relationships among the design context attributes. Once the performance attributes are established in the design context, then design altematives can be generated. A database of standard construction types for walls, roofs and glazings is developed to contain the material properties data required to generate design alternatives. This paper presents the knowledge acquisition and representation of building code and performance standards information, and also briefly describe the design process implemented in a prototype system.

Towards model based design - a case study: the modular design system

Abstract: The U.S. Army Corps of Engineers has developed a tool called the Modular Design System (MDS) to assist design professionals in the processes of planning, design, and construction document preparation for repetitive facility types. The use of early versions of MDS has demonstrated a reduction in time by nearly two-thirds typically required to design and award a construction contract. Initially developed to support Army Reserve Training Centers, the USArmy Corps plans to expand its use over a wider range of repetitive facility types. The current implementation is a hybrid document/model approach consisting of electronic drawings linked by an external database. Data consistency issues associated with this architecture limit its scalability. To meet expanded requirements, the USArmy Corps is developing a model based information approach utilizing emerging commercially available object based CAD systems. This redesigned information infrastructure marks a fundamental change from an implicit to an explicit model-based representation. Three key capabilities make MDS a powerful tool. First, the ability to capture and reuse corporate design criteria at the architectural function level. Second, it provides an integration framework for engineering analysis. Third, it manages and integrates the contract document production.The underlying MDS information infrastructure will move towards a model based approach. Future work will focus on collaborative processes such as conflict resolution and design review. Additionally, MDS offers the opportunity to transfer an information rich model downstream to operations and maintenance.

Issues in modelling and processing design standards

Abstract: In almost all engineering design contexts, design standards are used to specify performance requirements Design standards, or codes ofaccepted practice, have traditionally existed only in textual form. The complexity of the information expressed within a standard, and the fact that related information is usually scattered over many differentsections of a standard, makes standards hard to understand, prone to errors of omission during usage, and subject to multiple interpretations. This problem is compounded by the fact that standards are also subject to change as research leads to improved understanding of behavior. This paper first discusses the current approaches for developing andusing a design standard and then identifies several components that are needed to provide effective computer-based assistance to standards authoring, promulgation and evaluation. Next, the issues that must be addressed in providing these computer-aided standards processing components are discussed. As these issues are raised, an object-oriented approach to addressing these issues is also discussed.

Information model for performance driven computer integrated construction

Abstract: A generic information model for computer integrated constructionis presented. The viewpoint is performance driven design and construction, quality management and computerised information management over the life cycle of a building. The building information management process is divided into subprocesses by means of hierarchical activity models. Accordingly, conceptual data models controlling each subprocess are presented. For instance, the design process is controlled by a design data model. The data models also illustrate integration of traditional classification approach into product models.

A hyperdocument representation of the project for a user-adaptive groupware

Abstract: This paper describes the representation of a project inside a groupware tool dedicated to heterogeneous and short-lived teams. With a few exceptions, the concurrent engineering tools taken from industry and services are not used in building projects. These tools transpose in computer terms existing situations with hierarchical rules. Therefore, these tools couldn't respect the strong autonomy, of the actors in the French building context. The solution, we propose, give a relational vision of the cooperation and of the interactions existing during the processes of conception-construction in architectural works. Our first interest point concerns the representation of the actors, the documents and the assignments as a relational network and not as a hierarchical tree, mostly used in the groupware tools. In a second point, we use this relational network to produce a hyperdocument representation of the project data. This hyperdocument representation gives an adaptive view of the project organization and evolution to each actor in order to display information related to him only.

Integrating documentation for building .operation and maintenance in planning and design

Abstract: A general platform for a lifelong database is fundamental for the integration of information between design and management. Documentation from design as part of a facilities management system is necessary to retain the technical and functional quality of a building through its lifetime and to reduce the lifecycle costs. The use of computers have given us the opportunity of reducing the gap between design and management, even if it so far has tended to reinforce rather to weaken the organizational fragmentation that already exists. This paper focus on 10 important aspects for the development of computer integrated systems: Define the need for information in different management organizations; Avoid unnecessary information; Design simple systems; Develop a general platform - a lifelong database; relate to common standards; Produce the necessary information for operation and maintenance in design and construction; The implementation of an automated system demands a working manual system; An accurate database; A logical way of updating the database information and Link data to graphics.

Determination of effects of modifications during planning processes

Abstract: Usually, the co-ordination of design and planning tasks of a project in the construction industries is done in a paper based way. Subsequent modifications have to be handled manually. The effects of modifications cannot be determined automatically. The approach to specify a complete process model before project start does not consider the requirements of the construction industries. The effort of specification at the beginning and during the process (modifications) does not justify the use of standard process model techniques. A new approach is presented in this paper. A complete process model is deducted on the base of a core. The core consists of process elements and relations between them. Modifications need to be specified in the core only. The effort of specification is therefore reduced. The deduction of the complete process is based on the graph theory. Algorithms of the graph theory are also used to determine the effects of modifications during the project work.

Improving building life-cycle information management through dwumfntatiqm and communication of project objectives

Abstract: Most CurrentIy available computer tools for the building industry proffer little more than productivity improvement in the transmission of graphical drawings and textual specifications, without addressing more fundamental changes in building life-cycle information management. This paper describes preliminary research into the development of a fiamework for the aocumentation and communication of the project objectives of a building project. When implemented in an interactive networked environment, this fiamework is intended to promote multiple participant involvement in the establishment and use of a common set of explicit goals, from the earliest phase of a project throughout its life cycle. A number of potential applications for this fiamework are identified. The requirements for integrating this life-cycle information with a product model of the physical design of a building, in an attempt to document and communicate design intent, are also discussed.
