ST-1 Steel Frame Constructions

Business needs:
The ST-1 Steel frame constructions project deals with the business need of exchanging steel frame product data between constructional steelwork designer and other disciplines of AEC projects. Exchange needs to be addressed include:
  • Steel frame baseline information provision as input for steel frame design
  • From the steel frame design, steel frame spatial configuration data back to the building design for design coordination, collision detection and visualization
  • Early planning of steel frame fabrication, transport, assembly and erection.

Solution:
The ST-1 project defines the information requirements for exchanging steel frame spatial configuration data, IFC Object Model extensions to address those requirements, and a mapping specification between IFC Object model and CIMsteel Integration Standards V2.0 (CIS) for that steel frame information.
The solution recognises IFC specification as the specification for AEC/FM product data exchange especially between disciplines, and CIS as a detailed product data exchange specification especially for constructional steelwork.

Scope of work:
In Scope:
The spatial configuration data includes the shape and spatial arrangement of steel structures; i.e. the 3D shape of the members of the structural steel system, their locations, orientation and relative position, and connectivity to each other. A mapping specification for converting steel frame spatial configuration data between the IFC Object Model and CIS to be defined, allows for converting steel design baseline from building designers from the IFC form, into CIS form for steel designer; and steel design from steel designer from the CIS form to be converted back into the IFC form for building design coordination and visualization.
