The whole process engineering digital intelligent management platform is an engineering construction software system. It is primarily designed for project owners and is suitable for use by all parties involved in construction. It serves as an enterprise-level digital intelligent management platform for various types of engineering projects. With a focus on the management chain of planning, investment and documentation, as well as data transfer through BIM models, this platform incorporates built-in management standards. It standardizes, streamlines and digitizes the entire lifecycle management of engineering projects, from project initiation, planning and design, bidding and contracting, construction, to delivery and operation. This approach enables intelligent tracking, prediction and traceability throughout the project's lifecycle. The platform implements a primary responsibility system for the construction entities, aiming to achieve the "Five Guarantees and One Control" management objectives, which include ensuring safety, quality, progress, quality standards, integrity, and controlling investment.
