Requirements for RFID tagging process of concrete elements in building project

Concrete elements can be divided into many different types (e.g. facade elements, pillars and hollow slabs) which all have their own characteristics. We have completed two pilots to collect experience of embedding RFID (Radio Frequency Identification) tags into concrete elements, its effects to the different phases of a building project and processes related to them. The requirements of identification may vary for each type of these elements. The tagging process and the needs may also be divergent. Our experience clearly shows that identification of elements using RFID in larger scale requires remarkable engagement from the parties involved in the supply chain. The assurement of the readability of RFID tags in a completed building requires elaboration and clearly defined processes already during the modeling of a building. In this research we have focused on the information related to the elements and identification at defined action points to provide useful status data. This status and information is produced through all the manufacturing chain from production post-control.
