Using Engraved QR Codes to Connect Building Components to Materials Passports for Circular Construction
Computing in construction(2022)
摘要
There is an increased need for tracking building component information through its lifecycle(s) in order to reduce risk and uncertainty for reuse. Existing literature for material tracking focuses primarily on RFID for location tracking on equipment. However, Quick Response (QR) codes were used in this case study because of the low cost, speed of implementation, and accessibility. QR codes were applied to the structural wooden members through laser engraving. This proof of concept analyzes the challenges and advantages associated with using QR codes as the chosen tracking technology as well as engraving them as a permanent fixture.
