The benefits from the precast concrete construction IFC extension are e.g.:

• Enabler for streamlined product data exchange between building designers, element designer, element manufacturer, and contractors
• More efficient process without much of the manual re-input of data into different IT systems, and better possibilities for exploiting the data in downstream applications
• Better basis for further development of precast concrete production automation.

Relationship to other exhange specifications: The work will build on the existing Finnish precast concrete exchange specification BEC-system, which provides for well documented PCC design process definitions, and fairly comprehensive PCC product data definitions. The specification was defined by the industry, and has been tested in real industrial use. The basic idea of the proposed project is to use BEC-definitions as the basis, update and expand them where needed, assure the international applicability of the definitions, and document them as required by the IAI domain project procedures.

• Precast conctere building frame structures, and various types of elements, like beams, columns, slabs, facade the elements, etc.
• Spatial configuration of frames and elements, i.e. 3D shape (including features), location, and connectivity of elements
• Element reinforcement, material, and other quality properties.
• Element fixtures
• Definition of basic support conditions and loads on the elements as input for dimensioning purposes (?)
