Project Introduction
The Hanyu Financial and Business Center is located in the High-Tech Zone of Jinan City, Shandong Province. It features a planned total construction area of approximately 4.2 million square meters, with an investment of around 20 billion yuan. The A4 plot second section project, undertaken by China Construction Eighth Engineering Division First Construction Co., Ltd., covers a total construction area of 326,000 square meters. This includes 186,000 square meters above ground and 140,000 square meters underground.
The project comprises three towers, podiums, and an underground parking garage. Buildings 3 and 4 reach a height of 155 meters, while building 6 stands at 110 meters. The underground single-story area is notably large, spanning 36,000 square meters.
Application Achievements
Shortened Construction Period
Using work face management and construction simulation, issues in construction organization and material planning were identified promptly. This led to a reduction of nearly 30 days in the main structural construction period.
Technical Improvements
By fully leveraging BIM technology to simulate key and challenging solutions, the efficiency and quality of construction disclosure were significantly enhanced, saving approximately 30% of the overall time.
Cost Savings
Through the “Push Pin” method and stringent on-site quality control, combined with the use of rebar software for steel bar layout, cost savings amounted to several million yuan.
Brand Enhancement
The project received awards at the 2014 China Construction Association BIM Application Competition and the Longtu Cup BIM Competition, strengthening the BIM brand reputation.
Talent Development
Serving as a BIM pilot project for the company, it successfully trained personnel, with 90% of project staff becoming proficient in using BIM systems.

Section Division Workflow
Based on BIM 5D schedule management:
BIM-based visualization enables scheme optimization and construction disclosure:
Key and complex construction plans were simulated using visual models, improving first-time construction success through 3D animation disclosure.
The project applied BIM 5D and the “Push Pin” method to conduct quality and safety tracking management.
By collecting on-site quality and safety issues via mobile devices and synchronizing data with the BIM 5D platform for tracking, over 160 quality issues were addressed by November 2014, when the main structure was topped out. This effort saved approximately 3 million yuan in repair costs.
The project identified and resolved over 2,540 clashes, including more than 30 severe conflicts, resulting in estimated cost savings of approximately 2 million yuan.
Customer Feedback
1) BIM technology enabled over 90% of the engineering and technical staff (excluding some senior members over 50 years old) to master BIM proficiently. This accelerated the learning curve for recent graduates and new employees, and enhanced communication efficiency among construction teams and various specialized subcontractors.
2) By establishing multiple interface data sources and unified data transmission standards through the BIM 5D platform, the project effectively solved data identification and sharing issues, achieving comprehensive dynamic management of engineering data.
3) The use of electronic and 3D documentation improved work efficiency by approximately 30%.
4) The project achieved excellent construction quality on the first attempt, laying a solid foundation for subsequent Luban and Guoyou projects, and saving around 3 million yuan in repair costs.
