The RFID(Radio frequency identification device) are being used in various fields for monitoring components over few decades. Building information model files are used to extract and exchange the digital format of a physical component which can be virtualized. Combing RFID with BIM can help tracking the stages of manufacturing an element until the end use of it in construction industry. This combination can also be used in real time monitoring the work efficiency of mechanical element in a building. This technology is still under evolving stage around the world. Example of two construction projects implemented this method are,
· Maryland general hospital, Baltimore – case study 1
· Meadowlands stadium project, New jersey – case study 2
In UK construction industry this process of monitoring is widely used only in warehousing. Outcome of this research is to find the reason for not being used in UK construction industry. Whether the implementation is cost-effective? and Is there any cheaper alternate for “Active” RFID’s ? . which is a most efficient analysis software to collaborate RFID with BIM?
1.2 Background to the research:
Industry professionals have demonstrated the use of Radio Frequency Identification (RFID) Tags in construction applications in the past few years. RFID tags have successfully been used to track construction materials, equipment and tools. Studies indicate that the use of RFID tags in construction improves the overall process of construction. Does the construction industry need more motivation of adoption? Based on a previous research (2013 Ting et al) the construction industry needs more effective testing on live projects and more companies resist to change their practice. The research (Anoop Sattineni 2014) presented a framework for monitoring the movement of construction workers using RFID and BIM for safety purposes. The digital visualization is progressively growing in construction industry.
The use of BIM and RFID will allow the contractor to synchronise the construction with the design and logistics and find the errors or hypothetical situations way before the manufacturing process. Managing a project becomes ease and create a controlled collaborative environment on site. The previous research frameworks suggest the impletion of RFID & BIM in various fields like supply chain management, facilities management, Reduction of waste, Safety management (references 1.5).
The following image is from the National BIM report 2017 regarding the adoption of BIM in UK.
Use of BIM & RFID at site provided tremendous results in safety of workers as per the result done by (Arslan et al. 2014). The thesis conclude that the combination can be used to monitor the environmental conditions on the site and advocate its use for safety from an overall perspective.
Integration of RFID and BIM with Asset management:- The Asset management in a process in which the system is linked to a recorded model in efficiently aid in the maintenance and operation of facility and its asset. The BIM frequency identification device can make an efficient database.
Alternatives for RFID : There are various alternates available in the market instead of RFID. A brief comparison study will be made on this research based on their efficiencies and cost. Few know alternate devices/technologies are, BLE (Bluetooth Low energy), Barcodes, Laser, OBI, Embedded sensors and the NFC(Near field communication) . The comparisons will be made based on Cost, Data accuracy, range, data transfer rate, Level of detail and technical limitations.
EFFICIENT ANALYSIS SOFTWARE TO LINK RFID WITH BIM : There are many applications available in the market which provides BIM. The applications are grouped under architecture, Construction, structure, MEP, facility management and sustainability. List of few popular applications are,
· Autodesk Revit architecture
· Bentley architecture
· IES Solutions Virtual Environment VE-Pro
· Tekla structures
· Bentley structural modeler
· Tekla BIMSight
1.3 Research Methods:
The aim and objective will be carried out using the case studies of RFID implemented projects and through journals. Wide range of researches were done over the past 10 years. This research is mainly an observational research method. Will be an attempt to find more archival sources with specialist libraries.
1.4 Extensive Study:
As an extensive study from this research topic, a brief of its impact on clients, consultants and the contractors regarding the adoption of RFID & BIM or any alternative technology will be made through face to face questionnaire or through e-mails.
