The project information management system based on the digital application of engineering construction value chain can help the project related parties work together online, ensure that the information transmission is timely and accurate, and make sure the work flow is closed-loop management. Digital information assets can be used for advance warning, in-process alarm, post hoc analysis, and then form the organizational process assets.

Project Cost & Contract Management takes contract as the main line, combines project budget, collection, payment, change and cost to control the project in an all-round way. It can ensure that the project team can effectively make the cost prediction in the project progress, control the project cost in the whole process, find out the cost deviation timely, and put forward suggestions and take corrective measures before the deviation occurs.

Visual Smart Management can be applied with 3D to ND applications. By using the 3D models to integrate design, project management and site management information, the communication efficiency of the project participants will be improved obviously in the early stage and the construction period of the project. Several universities and consulting firms have reported that the application of VSP 3D-5D can save project cost and time, improve accuracy, and reduce errors and rework in the design and construction period. After the facilities are put into use, the project owner can also get the digital model and carry out digital operation and maintenance, which is applied with 6D-ND or more complex applications to support plant integrity management, safety emergency management, operator training and process optimization. The digital system of facilities provides the basis for digital twin applications.

By using scientific and systematic information means, the user can organize, manage, monitor and coordinate the construction activities comprehensively and efficiently, get the site information timely and accurately, and support the project decision-making effectively. Through the demonstration of planning, design, procurement and construction process, it can improve the communication between project stakeholders, improve the work plan, and clarify the scope of work, tasks and workload. Through informationized and refined construction management, human errors are eliminated, duplication of work is reduced, design and construction are coordinated, and prediction and analysis of planned and actual progress are realized.
