In one construction production process, a huge quantity of data is used and it has complicated relation among companies and systems. But the system environment which associates it is not established by the present construction production. Therefore, when the event which blocks a process plan occurs, great cost occurs in change of a process plan. This paper shows how to realize the increase in efficiency of management by the information sharing system using XML technology and SVG technology. And, the "Parts and Packets unified architecture" system using RFID and Active Data Base shows the technique of preventing the increase in the cost accompanying change of a process plan.
