A study is for improvement in practical use of RFID+4D. In the yard of construction industry, using information has become more important part to control total process. One of the way to improve the information using that comes from each step, RFID is getting attention. But it`s not really adapted on construction industry. Especially, a study on the curtain wall part has a problem of engineering process. Each steps of curtain wall process are separated. If it` could be connect totally, controling information of curtain wall from producing to fitting become more efficient with adapted RFID+4D.
