A decision support system for the selection of curtain wall systems at the design development stage

In high rise building construction projects, curtain wall is one of the most widely used exterior finishing components and has a major influence on the overall building operational costs and efficiency in terms of CO₂ emissions. The selection of curtain wall systems involves numerous technical, environmental and economic factors, and impacts on all project stages from concept design, through manufacture to installation and operation. The current way this important decision is being made in the business process, and its simplification, are two important issues that are still unexplored in the literature. After investigating the drawbacks of the current business process using a retrospective case study and an industrial survey, a decision support system (DSS), which consists of a process framework and an integrated relational database as a central repository for the main curtain wall systems and their engineering parameters, is proposed as a potential solution. The DSS developed not only enables the resolution of the main issue of the selection of curtain wall systems at the early design development stage but it also helps specifiers identify multiple technical and commercial options that could be presented to clients in real time.

A decision support system for super tall building development

Super tall building projects commonly inherit a slow and lengthy decision making process due to financial uncertainties, in spite of large investments. However, current decision‐making practices depend upon detailed cost estimating and scheduling during the design development phase and not rough cost estimating and scheduling during the schematic design phase. Discrepancies between a project budget and program with estimated construction cost and construction period often result in architect and consultants having to perform costly re‐design work. To mitigate these issues, this study proposes a decision support system (DSS) model. An interim design development phase is introduced between the schematic design phase and the design development phase. Design alternative generation, database, cost and schedule estimation modules are developed. The design alternative generation module provides design alternatives that change proportionately in response to increases or decreases in the number of building stories. The database module is established for cost and schedule estimation modules. The cost and schedule estimation modules produce construction costs and construction period for design alternatives. Finally, the proposed DSS is validated through the case study of an ongoing real super tall building. Ultimately, the new DSS can assist project control groups in performing efficient and financially beneficial decision making in terms of construction cost and construction period. This research provides a fundamental step towards the development of the DSS for super tall building projects. Copyright © 2012 John Wiley & Sons, Ltd.     

A regulation evaluation system: a decision support system for the Building Code of Australia

Building regulations have historically been developed and drafted relying on groups of experts and their particular perceptions of what was an acceptable level of risk and what costs can be afforded by the community for improved health, safety or amenity. New technology, particularly in the areas of building design and material sciences, and the development of performance-based standards and codes are demanding major changes to the way in which regulations are developed and how they are assessed to ensure that any changes are in the community's interest. The regulation evaluation system described here provides a computer-based framework on which proposed changes to the Building Code of Australia (BCA) may be systematically assessed. The system requires any proposal to amend the BCA to be clearly identified together with all alternatives which achieve the desired objective. Direct costs and benefits are identified and quantified, making use of internal and external data. Where there is inefficient data, stochastic modelling is employed. The system not only aids decision makers by providing all available information, it also provides a transparency to the decision making and regulation development process.

A group decision support system for implementing value management methodology in construction briefing

This paper describes a group decision support system (GDSS) developed in response to the need of a computer supported collaborative work environment for implementing the value management (VM) methodology in construction briefing. The GDSS is based on the VM methodology that allows a client to define and represent his or her requirements with functions and functional performance, to bring forward ideas to achieve the functions, and finally to evaluate and highlight the ideas against the functional performance for further development in design. The conceptual framework, design, implementation, use of the GDSS are addressed and described in that order. The system is complementally evaluated through a field study and an experimental study. It is concluded that the GDSS can effectively facilitate the implementation of VM in construction briefing. In addition, the GDSS has big potential to improve the performance of VM studies in terms of the enhanced participation and interaction, the shortened time for tasks, and the improved satisfaction with VM workshops. Research limitations and knowledge contribution of this study are also discussed.     

Decision support software approach to the assessment of stone masonry bridges

This paper identifies the need for a formalized approach to the assessment of the integrity of stone masonry bridges and develops the concept of the use of a computer database and suitable software to support the practising bridge engineer in the decision-making process (decision support software, DSS).

The different standard techniques of assessment of masonry bridges are outlined and their limitations described. The common faults associated with masonry structures are discussed and the problems of identifying these faults are described. The part played by the individual components of a masonry arch bridge is outlined and the significance of faults on the individual components of the structure is discussed.

Database development and operation of the DSS are detailed and their value to the bridge engineer is discussed. The system is illustrated with a demonstration run.
