All you need to know about RFID !
Radio frequency identification (RFID) technology has been widely used in the field of construction during the last two decades. Basically, RFID facilitates the control on a wide variety of processes in different stages of the lifecycle of a building, from its conception to its inhabitance.
In this paper we are going present the establishment of the RFID technology in four main stages of the lifecycle of a facility: planning and design, construction and commission and operation and maintenance.
Radio frequency identification technology demonstrates a great potential in the monitoring of constructive processes. Among these operations, a wide variety of them are carried out before the building work starts. On the one hand, several processes are related to the conception of different RFID systems aiming to facilitate the constructive process. On the other hand, one can consider the use of RFID in the production of different materials used in the building construction.
Monitoring is a determining task to achieve an accurate measurement of progress in building sites. In addition, this control strategy helps manage labour, safety and equipment. All of these aspects are separately evaluated with the help of RFID tags. However, there also exists a variety of works in which different methods are integrated to manage an overall project.
The continuous movement of materials and workers in the job site, together with the advances in the works, make the monitoring of resources in the construction environment truly complicated. RFID technologies are not able to control every process carried out in the workplace. However, the combination of several technologies can automate the monitoring systems, helping measure the progress of every process. Thus, laser scanning and photogrammetry can be used for site representation, RFID and barcodes for collecting actual working hours and modelling for information purposes and updating planned data . The control of the status of materials in the job sites by means of RFID technology is a useful tool to show a 3D model of the building under construction and to compare the planned model with the built one. To visualize the construction progress in real time we propose the integration of building information management (BIM) models and augmented reality. They suggest the use of an RFID system to track different components.
Building information management (BIM): This process, providing the physical and functional characteristics of facilities, is going to play a critical role in the transformation of the construction sector. We have presented a system based on the combination of laser scanning and RFID, aiming to generate BIM models for the monitoring of construction process.
