The Machang Technology New City Commercial Complex project, located in the southern core area of Gui’an New Area, serves as a major gateway and landmark urban complex for the region. Recently, CCCC First Highway Engineering Co., Ltd. partnered with Luban Software by signing a BIM cooperation agreement to integrate Luban BIM technology and services into the project. After four months of on-site service, the project has achieved remarkable results in economic benefits, talent development, construction guidance, multi-calculation comparisons, and scheme simulation.
1. Project Introduction
The total construction area of the project spans 184,856 square meters and is divided into two plots, south and north, connected by a modern steel-structure commercial corridor.
The southern plot features:
– 2 underground floors (-10m)
– 4 above-ground podium floors
– Two tower buildings, each with 19 floors reaching 73.75 meters in height
The northern plot includes:
– 2 underground floors (-10m)
– 2 above-ground podium floors
– One tower building with 13 floors reaching 66.8 meters in height

2. Comprehensive Impact of BIM
Within just a few months of Luban BIM technology consultancy on-site, the project has realized comprehensive economic benefits exceeding 1.4 million yuan. These include:
– Direct economic benefits: 1 million yuan
– Indirect economic benefits: 400,000 yuan
– Major drawing issues identified: 20 structural and 28 steel reinforcement problems
– Auxiliary design optimizations: 1
– Detected clashes: over 8,000, with 25 critical areas requiring optimization
– Optimized mechanical and electrical pipeline layouts, resolving all collision points in the northern basement and increasing local net height by 10 cm
– Total saved working days: 30
– Discovered omissions in civil engineering quantities amounting to 447 m³ of concrete and 471 tons of steel reinforcement through comparative analysis
3. Key BIM Application Achievements
1. Site Layout Planning
This project faced challenges such as a narrow construction site, limited working surfaces, large construction volume, and a tight schedule. BIM technology was used to efficiently plan and arrange the construction site.
2. Benefit Analysis
Management relies on accurate data, and effective project management depends on managing engineering data precisely. By comparing BIM model data with bill of quantities and actual usage, discrepancies were identified: nearly 500 m³ difference in concrete volume and over 400 tons difference in steel reinforcement quantity.
3. Early Detection of Drawing Issues to Reduce Change Orders
Through preliminary modeling, 20 structural drawing issues and 28 reinforcement drawing problems were detected, allowing for proactive corrections.
4. Visual Transparency
A BIM model was established to identify drawing problems and simulate on-site construction challenges in 3D, improving work efficiency and reducing rework.
5. On-Site Material Planning
With support from the Luban system, managers control the quantities of concrete and formwork for each grade based on model data, preventing unnecessary losses caused by underreporting.
