It is certainly unusual to see an advanced fingerprint and face recognition system, something rarely seen outside of futuristic movies and the most modern of office buildings, being used at a noisy construction site, as the way of controlling access for its workers.
Country Garden Holdings, a construction firm in Dongguan, a mid-sized city in China's Guangdong province, has installed such a system at its Country Garden-Chashan Mansion project. Ou Peikang, an administrator of the Chashan project working on the construction site, said, as he was placing his hands on the scanner and facing the monitor, "the workers got used to the system in a matter of days.”
"All the construction workers enter the site every day through the system," Ou added.
Wang, a worker with many years of experience in the field, said, "This is the cleanest and most orderly construction site I have ever seen in my career as a construction worker." The methodic approach to every aspect of the site is immediately obvious as soon as one reaches the entrance gate: the entrance area is inlaid with grooves so vehicles can be washed and cleaned by an automated car wash and the accompanying spraying and aspirating systems.
A digital screen, also located in the entrance area, displays the current weather information, including PM2.5, PM10 and humidity, constantly monitoring the environment within the site.
Workers on the site can also access information about construction materials by scanning the QR code with their smartphone.
