Nowadays, the people's demand for housing has shifted from "yes" to "no", and they are even more eager to have comfortable and safe living conditions. The quality of construction projects is directly related to the interests and well-being of the people, and is an important carrier for promoting high-quality development and creating a high-quality life for the people. And engineering quality supervision has become the key to promoting the high-quality development of the construction industry. In recent years, the construction industry has increased investment in scientific and technological research and development, and through digital means, intelligent construction and supervision have been carried out, thereby promoting the improvement of construction engineering quality and high-quality development of the construction industry, maintaining the bottom line of engineering quality and safety, and creating high-quality construction products that the people expect. The construction of smart construction sites is an important way for digital supervision to help improve project quality. In recent years, Taizhou City, Zhejiang Province has carried out the construction of a smart construction site management platform and achieved positive results. The relevant person in charge of the Municipal Housing and Urban Rural Development Bureau told reporters that the "Smart Construction Site" management platform includes 10 subsystems, including lifting machinery management, migrant worker management, video online monitoring, dust online monitoring, supervision work evaluation, key position personnel management, model construction site evaluation, testing supervision, and quality acceptance, achieving resource integration, centralized control, real-time supervision, and full traceability goals. What role can the construction of smart construction sites play? For example, the tower crane visualization system monitors the working status of the tower crane in real-time, monitors the lifting objects and personnel safety. Install smart nuts on the tower crane. If the swing of the tower body is large and the smart nut is triggered, the warning message will be sent to the management personnel's mobile phone through the app and SMS within 40 seconds. The lifting machinery management system uniformly records the construction lifting machinery, configures electronic certificates for each component, and binds the electronic certificates one-on-one with the equipment, effectively solving problems such as equipment licensing and overdue use. The online dust monitoring subsystem is effective in monitoring construction noise and PM_ 2.5 PM_ 10. Collect wind speed and other indicators, and upload monitoring data in real-time to the smart construction site management platform. The system automatically distinguishes monitoring data, sends warning information to construction enterprises and competent departments, and automatically starts corresponding dust reduction equipment to achieve the unity of monitoring and control. Industry insiders say that digital supervision enables regulatory personnel to detect safety hazards in a timely manner without being on site, and manage equipment, construction personnel, progress, and environment. Supervisors can timely grasp the frontline progress, safety, environment, etc. of the construction site, and efficiently and conveniently supervise the construction site. Digital supervision of project quality is an important way to improve the project quality assurance system. The relevant person in charge of the Ministry of Housing and Urban Rural Development said that all regions should earnestly grasp the key links of digital supervision of project quality, take "quality power", "digital China" and "digital housing and construction" as the starting point, coordinate the construction market and construction site, and further stimulate the potential of digital supervision. Establish and improve digital regulatory rules and regulations, unify the digital regulatory data standard system, explore the establishment of the "Internet plus regulation" model and auxiliary decision-making mechanism, build a market environment of integrity, law-abiding, fair competition, and quality pursuit, and achieve "smart regulation". Focus on digital supervision of project quality inspection, build a national, provincial and municipal three-level digital supervision system of project quality, and speed up the overall
