A Design-Decision Making Model for Detail Design of Building Elements

Abstract

In this study, it is aimed to develop a design-decision making model which helps the building element detail designers to create design alternatives according to the design factors and determine the most appropriate solution by evaluating the alternatives. In the development of the model, the general design-decision-making process phases (analysis-synthesis-evaluation) adopted by various theorists looking at design in terms of system approach were followed as a method. In the analysis phase, the preliminary information obtained from the previous design phases is analyzed and design factors that can affect the detail design are determined. In the synthesis phase, alternative detail design solutions are developed according to the design factors and the relations between them. Thus, feasible detail design alternatives that can meet the design objectives of the building element can be obtained. In the evaluation phase, by using an appropriate evaluation method, feasible alternatives are evaluated according to design factors and the most suitable detail design alternatives are selected. The developed design-decision-making model allows designers to use his intuitive power and creativity during the creation of a detail design alternative and simplifies the understanding and control of decisions both in the creation of alternatives and in the evaluation process. Automating the model and integrating it with BIM systems will eliminate the process length and time loss, enabling more efficient use of the model.
