MCC Capital Engineering & Research Incorporation Ltd. (MCC CERI) has created smart CIM platforms at the park, district, and city levels, covering the entire lifecycle management of planning coordination, construction control, operation management, urban health check, and smart government affairs. These platforms integrate multiple business dimensions, including municipal facilities, rail transit, energy and low-carbon development, and industrial parks, to create an integrated urban planning, construction, and management platform. In the Daxing Airport Economic Zone Planning and Construction Information Platform project, MCC CERI constructed a 50 km2 twin city of the airport economic zone, covering data throughout the entire life cycle of planning, design, construction, and operation, and created an integrated management and control platform for the planning, construction, and management of the airport economic zone.
