Founded in 1962, China Construction Fourth Engineering Bureau currently employs 16,000 people and operates as a subsidiary of China State Construction Engineering Corporation. This group ranks 52nd on this year’s Fortune Global 500 list, generating an annual revenue of approximately 600 to 700 billion yuan. Their expertise lies in constructing high-rise buildings, having completed 30 projects taller than 200 meters and three exceeding 400 meters, including landmarks like Jingji 100 in Shenzhen and the East and West Towers in Guangzhou.
While utilizing iTWO software, Yan Pingyu organized his team into five specialized groups responsible for modeling, quantity calculation, pricing, time control, project management, and monitoring. Group leaders have continuous access to real-time data, enabling efficient coordination.
During the construction of the IFC Tower in Dongguan and the Yinhu Metro Station in Shenzhen—both projects by China Construction Fourth Engineering Bureau—iTWO demonstrated exceptional capabilities in controlling time and costs. From these experiences, six core values were identified.
First, Visual Collaboration and Process Innovation. iTWO provided a robust communication platform, connecting various departments seamlessly and fostering innovation throughout project workflows.
Second, Precise Detection and Timely Feedback. Quickly identifying errors and providing prompt feedback is vital during construction. While building the IFC foundation, iTWO helped avoid thousands of potential errors, ensuring both safety and time savings.
Third, Accurate and Fast Quantity Price Analysis. To better control costs, the bureau incorporated national and local standards into the model. iTWO quickly verifies compliance and highlights profit and loss areas. Yan Pingyu compared iTWO’s calculation and pricing functions with other local software and found only a 1% error margin, which significantly boosted his team’s confidence in the platform.
Fourth, Optimized Scheduling to Maximize Profit. Based on experience, Yan Pingyu typically divided each 40,000-square-meter floor into 11 sections with dedicated workflows for foundation construction. However, simulations with iTWO revealed that splitting the floor into 13 workspaces could save 18 days and reduce costs by 2%, allowing for a more efficient work schedule.
Fifth, Information Integration and Virtual-Real Comparison. Monitoring progress across large-scale projects can be challenging. Using the iTWO platform, project managers gain clear visibility into which parts of the project are on schedule and which require acceleration. The platform compares actual progress with planned milestones and tracks actual costs against budgeted expenses, enabling timely problem identification and resolution.
Sixth, Ensuring Data Authenticity. Accurate data is crucial as project profits fluctuate with process changes. Previously, data was manually recorded, which posed risks of errors. With iTWO, data is directly entered into the system with no unauthorized modifications allowed. Any changes are traceable, ensuring data integrity and supporting effective project management.
