QR Codes have taken our lives by storm in the last decade. Being used in all areas from home to retail stores. And the growth does not seem to decline, with latest use the well-known COVID tracking system. QR codes have many functionalities and are being used in all industries around the globe.
So what is a QR code and why was it invented?
QR code is an abbreviation for Quick Response code, a two-dimensional bar code that was first designed in 1994 by Masahiro Hara from the Japanese company Denso Wave for the automotive industry. Its purpose was to track vehicle manufacturing and was designed to allow for high-speed component scanning.
Usually, the QR code will be located on a white background which makes it easy for imaging devices to read. The initial design was influenced by the black and white pieces on a Go board.
The process by which the device reads the QR code is called Reed-Solomon error correction. This occurs until the image can appropriately be interpreted. The required data is then extracted from the patterns that are present in both the vertical and horizontal components.
There are four standardized encoding modes to store data efficiently, namely:
Uses for QR codes in the Construction & Operating industry:
The main use for QR codes has always been for consumer advertising since it provides a way to access a brand’s website easier and more quickly than by manually typing a URL.
However, QR codes are not just for company promotions anymore. Business can use them for assets inventory, logs, and ticketing and so much more.
Through the years, construction and operating companies have seen the benefit that QR codes can provide to their business and have adopted some of these functions.
Some of the functions include:
- Verifying tools and materials: All materials and tools being used on site needs to adhere to certain codes and standards to ensure quality and safety. Verifying paper-based documents can be cumbersome, so many companies opt for QR codes placed on material and tools to ease the process.
- Latest revision drawings: Not knowing whether the latest revision drawing is being used on site is a common occurrence. This can lead to costly mistakes and sometimes even injury to workers. Therefore, placing QR codes on drawings, building elements such as pillars and in site offices can provide a worker immediate access to the database to ensure that the latest drawing is being used.
- Manuals: Manuals is a very important aspect when it comes to the maintenance of a finished construction project. Thousands of manuals can exist, usually paper-based and stored in the office with digital copies only available to office staff. With a QR code placed on the objects that needs to be maintained, easy access can be provided to the maintenance staff to that specific manual. Eliminating errors and making for more productive work.
How does QDot utilize QR codes?
Did you know that QDot stands for Quality Dot? With the Dot referring to a QR code label hosting all the project information.
QDot has built the application around the use of QR codes, making for easy access to Construction information such as Design drawings, ITP’s and right through to operating and maintenance manuals.
We are also utilizing this function to link different projects together on the app which allows for traceability of materials, processes, and signoffs.
QDot aims to lead the way in new technology and help bridge the gap to easy and accessible data. To know more about how QDot utilizes QR codes in the construction and operating industry, please visit www.qdot.co.nz or contact us at email@example.com.
