I. Project background
1. Industry Background
Smart construction site has become the development trend of the industry
The smart site scheme takes into account the demands of multi-party supervision and can realize the efficient control of the whole project. It is the best solution to solve the current problems of site management and also the development trend of “Internet +” in the construction industry.
National new infrastructure to enable multiple policies to promote
With the continuous development of new infrastructure, many provinces have introduced policies to vigorously promote the construction of smart construction sites, boost the sustainable, stable and healthy development of the construction industry, and facilitate the rapid construction of new national infrastructure projects.
There is an urgent need for intelligent site supervision
Government regulatory departments and construction enterprises have an urgent demand for construction site management information platform construction, AI, big data, cloud computing, Internet of Things and other technologies help the transformation and upgrading of the construction industry.
2, the industry pain point
1) Regulation is difficult
The construction project volume is large, the site environment is complex, and the project involves many links, such as construction quality, safety, progress, materials, equipment, environment, personnel, etc., which makes the overall supervision of the site difficult and the control requirements of each link extremely high.
2) Difficult personnel management
Construction site project personnel number is large, mobility, lack of effective organization, supervision is not in place easy to lead to confusion of personnel management, labor disputes, site illegal operation, bring great difficulty to enterprise labor management, at the same time there is a great risk.
3) Frequent safety accidents
Construction operations are high-risk, and there are many potential safety hazards for people, vehicles and objects on site. Construction sites lack intelligent supervision means for construction operations, and they cannot prevent and give early warning of safety accidents, resulting in frequent safety accidents and huge losses.
4) Information island is serious
There are many sites, many collaborators, scattered data without sharing, fragmented application, easy to form information islands, leading to the separation of business processes, difficult docking of all parties, low efficiency of collaborative work, low efficiency of construction operations, and many blind spots and loopholes in project management.
5) The informatization level is weak
The traditional extensive supervision informatization level is weak, and the digitalization and intelligence of construction sites are in urgent need. There is an urgent need for cross-domain data fusion, comprehensive perception of people, vehicles, objects and environment, etc., and intelligent linkage of business to realize visual, manageable and controllable projects.
3. Development trend
As more and more hardware devices are deeply combined with the project, more and more systems are used by the construction unit. Various applications are chaotic and scattered, and data is fragmented and cannot be used uniformly, resulting in poor experience. Through a unified platform to integrate all business data, centralized management, combined with AI, big data, cloud computing and other technologies, to achieve intelligent decision-making and management of site supervision.
