This paper analyzes the drawbacks and causes of the current modular project management platform for cement engineering, and innovatively proposes a smart engineering project management platform. The platform is based on project management data, led by project implementation planning, with time as the management axis, each sub project as the spatial positioning, business activity management as the core, and progress, quality, and cost management as the focus of performance evaluation. By constructing five modules of "database, project implementation planning, business management, performance management, and functional management", the platform has achieved intelligent guidance for various tasks and achieved interconnectivity of project management process data, improved the intelligence level of project management.
