The technical strategies available in the design and construction industries seem overwhelming. Perry Forsythe, a professor of architecture management at the University of Technology Sydney, recently gave a presentation at the Frame Australia event in Melbourne, explaining each of the major technologies and their effect at the construction cycles.
According to Forsythe, building technology can be divided into four categories: automatic data collection, intelligent processing, new reality, sharing and connectivity. These can be considered in five phases of construction: design, manufacturing, component supply, construction and construction operations and facility management.
The automatic collection of data can be completed by RFID technology, and the tag with ID identity identification is cheap and easy to be recognized and read. The meaning of the tag ID, the tag’s use object and the tag definition given by its database. The focus of the use of RFID technology is to ensure the correct reading of ID tags and how to use the data in the definition ID database.
The application of RFID technology in the construction and living space is roughly divided into two stages: the construction period of thestructure trunk and the management of people or objects after the construction.
The use of RFID during the construction period is usually in the management of building materials and construction projects. For example, steel skeleton construction management in large buildings, using RFID tags to define the classification symbols and serial numbers of building components, can accurately manage which steel brick building materials belong to which building, which floor, which component type, which column Line or serial number. In addition, the management of the construction project can be related to the engineering category, construction group or team, construction date record and tracking, etc. The construction management can control the warehousing, scheduling and construction period of the building materials, and even as the basis for clarifying the responsibility at the future acceptance.
The introduction of RFID technology has effectively reduced a large number of manpower copying and recording operations, improving work efficiency, data correctness and reducing labor costs. However, the use of current RFID tags is not yet permanently left in building materials. Usually, the positioning or application of the building materials components is completed. After the acceptance is completed, the RFID tags are removed and reused in the unfinished building materials and the engineering control of the next stage.
The building after construction, the RFID tag is combined with a sensor such as an accelerometer, a torque meter, or a water pressure gauge. RFID tags and sensors can be placed in the important beam or main structure of the building body, and the sensed values can be read out by wireless transmission technology, and the displacement, shape or groundwater level of the beam and column can be tracked regularly. Basis for assessing the safety of beams and columns or the impact on buildings when an earthquake occurs.
Now, a more advanced form of radio frequency identification is called active radio frequency identification, which can emit its own signal (a radio frequency identification device that scans and reads only bar codes is called passive radio frequency identification). These measures can be used to issue warnings about the moisture content of the wood in wet areas and balconies, and indicate the need to take action on any deteriorating material conditions.
