In this course, a holistic approach is taken to the hardware of a building of which all structural elements are examined individually previously. The two production processes, which are on site and off site productions, in the construction industry are examined. The conventional way of constructing a building, site organization and management, production stages are covered by on site production. Off site production deals with the prefabricated building systems: prefabricated reinforced concrete panels, frame structures, timber panels and frame structures, steel structures. The target of this course is to enable the students to gain knowledge on the modularization and standardization as well as the work flows in the building production processes and mass productions. Subjects are examined in terms of architectural design principles.
