ABSTRACT
Integrated structural life cycle design includes the tasks and methods in the design process. Designers in co-operation with the owner create alternative investment plans, and make a multiple criteria analysis leading to decision-making between alternatives. The analysis of clients’ needs is a preparatory phase of the building project. This phase deals mainly with the use and the spatial requirements of the buildings, and it is the responsibility of the client, the architect and the contractor. The phase of conceptual design is the most important, because the decisions made in this phase have a strong influence on the economic, environmental, aesthetic, functional and technical quality of structures. The ranking of design alternatives ends the sketch design phase and results in the draft designs. Ordinary mechanical design is performed using conventional design methods. Acoustic design usually includes airborne sound insulation, impact noise level control between spaces and control of vibrations of structures during use.
