Steel fabrication is a kind of manufacturing work for construction industry.
The CIM technique has been used to computerise the steel fabrication activities, such as automatic painting, robotic welding, CAD drawings, cutting machine, through a controlled by a computer programme, etc. In the context of this dissertation, the Simulator can be seen to be an object oriented knowledge-based system, which specialises in the process of steel fabrication. It is used to demonstrate process of steel fabrication. However, it should be noted that the Simulator is not classified as a CIM technique, because it control directly the manufacturing activities in the fabrication shop. But due to the real time function is available in the Simulator, it can be used as assistance to the process manager for tendering, reducing production cost by increasing the manufacturing productivity, determining fabrication process, estimating fabrication cost, enabling the engineer to decide on the steel section design, connection design, and so on.
