In Shenzhen International Convention and Exhibition Center project, 5G intelligent scheduling system realizes the average daily installation volume exceeding 1,200 tons; Hong Kong-Zhuhai-Macao Bridge steel box girder project compresses the construction period by 23% through the digital twin technology; Xiong'an New Area, a super high-rise building applies the modularized construction to achieve the speed of three-day one-floor construction ... These practices reveal that modern Steel Structure engineering is reconstructing the progress control paradigm through technological innovation.

I. Digital progress planning system

BIM-4D dynamic projection technology

The steel structure project adopts Navisworks+Project linkage 4D simulation system, and a stadium project identifies 36 process conflicts in advance. By simulating 300 construction scenarios through Monte Carlo algorithm, the risk of schedule deviation was reduced to ±5%.

Intelligent Gantt Chart Optimization

Primavera P6 platform integrates resource constraint algorithms, and a bridge project compresses critical path duration by 18%. The material-machine-human coupling model developed by it realizes the response time for dynamic adjustment of schedule ≤ 4 hours.

Intelligent Production Scheduling System

Prefabrication Plant Digital Twin

A steel structure processing base in Shanghai deploys MES system to monitor the status of 32 production lines in real time. Through genetic algorithm optimization of cutting scheduling, the material utilization rate was increased to 98.7%, and the average daily production capacity exceeded 800 tons.

Intelligent Logistics Scheduling

With UWB positioning + AI path planning system, a super high-rise project increased the efficiency of component transfer by 40%. The tower crane intelligent anti-collision system developed by the company reduces the waiting time for hoisting operations by 65%.

Modularized rapid construction technology

3D Modular Unit Prefabrication

A project in Xiongan adopts 18×12×6m standard module, and the degree of completion of factory prefabrication reaches 95%. The on-site installation speed reaches 2,000 square meters/day, shortening the construction period by 45% compared with traditional construction.

Hydraulic overall lifting

Hangzhou Asian Games Stadium applies 2000-ton lifting system to lift 800 tons of steel roof in a single lift, with synchronization accuracy of ±2mm. the PID closed-loop control algorithm developed by it stabilizes the lifting speed at 0.8m/h ±5%.

IV. Innovative Mode of Resource Guarantee

Blockchain Supply Chain Management

A key project establishes a steel traceability alliance chain, and the response time for handling abnormal pieces is compressed from 72 hours to 4 hours. Smart contract automatically triggers replenishment instruction, and inventory turnover rate is increased to 18 times/year.

Equipment Sharing Cloud Platform

The Yangtze River Delta region integrated 320 sets of heavy machinery, and equipment utilization rate increased from 58% to 82% through 5G+BeiDou scheduling. The preventive maintenance system it developed reduced breakdown downtime by 70%.

V. Real-time progress monitoring system

Drone Inspection System

DJI M300 is equipped with LiDAR, and an airport project realizes daily scanning of 200,000㎡ construction surface. Through point cloud comparison technology, the accuracy of progress deviation identification reaches ±0.5%.

Internet of Things Progress Kanban

Deploying 500 RFID tags + UWB positioning terminals, a complex project displays the status of 2,000 components in real time. The progress prediction model it developed has a weekly plan completion rate prediction accuracy of ≥95%.
