to design & deliver Yanggao South Road Tunnel”

Yanggao South Road Tunnel

The reconstruction of the Yanggao South Road covered the area between the current Century Highway and the Pujian Road cross-route bridge, and measures a total of 1.95km (1.2 mi).

The road, tunnel structure, Zhangjiabin Bridge, rain sewage pipeline, traffic sign and lines, signal lights, ventilation, monitoring system, power transmission and distribution, architecture, greening, and related equipment—as well as the initial greening and pipeline relocation—cost RMB ¥1.455 Billion in construction and installation, with the total investment amounting to RMB ¥2.47 Billion [USD $386 Million].

The Dassault Systèmes 3DEXPERIENCE platform version R2015x was selected as the BIM platform for the entire process. SMEDI realized the following benefits by adopting the 3DEXPERIENCE platform:

Data Security

The platform adopts the Cloud platform and the structure model of the central server to unify the database of the project. This provides reliable data security protection for the project.

Ease of Simulation

The platform supports the type expansion of the BIM model and adopts the approach of self-defined uniform type in the Yanggao South Road Project. The side-stones, parapet, and asphalt in the tunnel structure are laid out in a unified manner. This gave great convenience to the latter-stage quantitative surveying and simulated implementation.

Cross-Model Clash Detection

With the multi-disciplinary, real-time-coordinated BIM platform, the design professionals in the structure, bridge and pipeline fields can carry out real-time design work on the same platform. This synchronized modeling function can instantly identify any errors in the design process and quickly check for any mutual interference between different models.

Workflow for Large-Scale Modeling

The BIM modeling workflow approach on the 3DS platform has been initially formed. The current software format can support a large-scale data model for a 100km roadway. The entire BIM area covers the initial solution design, the intermediate detailed structure design, the latter-stage implementation simulation, and project reporting.

Efficiency of Templates

The innovative re-use function of the knowledge template library can, with the template function provided by CATIA®, rapidly exemplify the different components in the tunnel structure, thereby avoiding duplication in modeling and enhancing working efficiency.

In the demonstration and proofing stage of the project solutions, the BIM technology was introduced to visualize the 3D design, to compare the various solutions, and to optimize them. Satisfactory results were achieved in the briefing sessions for government leaders and the project owners.

In the design stage, both BIM and regular design methods were employed, and the design results were checked to help ensure that the quality of the design drawings was secured.

In the tendering stage for the construction, the joint design team made a significant breakthrough in estimating quantities of building materials based on BIM, and successfully acquired from the BIM information the quantities of concrete and steel for the main structure, and those used to protect the structure. 65% of the estimate was checked against the traditional calculations, and was used in the checklist for the formal tendering of the project.
