Through the data collection of field managers and workers in the early stage, we have established the personnel database of Jiangbian Phase IV Intelligent Construction Site, which lays the foundation for the later application. In the construction site, the hardware facilities such as smart meters, smart water meters, site treasures, dust noise monitoring equipment and face recognition system are installed in place. After the information is uploaded to the cloud platform, we distribute the smart safety helmet to every worker. Through downloading mobile APP, project managers can check workers'attendance, task assignment and communication, monitor the progress of tasks and other operations in the mobile terminal. Moreover, the platform of computer and mobile terminal organizes many fragmented data and presents them in the form of various charts. It is a step-by-step improvement process for safety quality, cost control and management level.

With the help of the intelligent platform, the safety and quality of the project have been guaranteed, and the construction progress has been greatly improved. This shows us the results of the previous investment. All the hard work has not been wasted. We call it the "Fourth Phase Speed by the River".

Through the construction of Intelligent Platform, from the project level to the company level, we all have a profound understanding that this platform can be used not only in the project site, but also in the company management. It can systematically manage the quality, cost and progress of construction. This is the first time that we construct and apply the intelligent construction site. It is also the trend of future development. We should change the traditional management mode to the direction of intellectualization and informatization, so as to become a strong brand enterprise. In the future, we will continue to work hard to maintain the intelligent platform and carry out the intelligent reform to the end.
