Transforming Tunnel Coordination and Constructability with Computational BIM

共享此课程

说明

On rail infrastructure projects, consultants provide tunnel ring models for entire alignment, created using a two-point adaptive family based on the track center point via Dynamo. But these models lack detailed tunnel features—segmentation and dimple holes. Coordination with stakeholders requires complete tunnel models with segmentation and dimple holes. We must develop this detailed model to accurately place services brackets along the tunnel. The ring comprises eight segments, including a key segment with a varying location. A family of these segments, with a rotation parameter set by the tunnel's center point, is essential. Our process involves deriving the tunnel's center from track center points using geometric translations. Dynamo makes placement points for adaptive components. The angle of rotation is recorded on the site for the key segment in XYZ, and we develop construction model using that data. This construction model aids subcontractor in accurate service modeling.

主要学习内容

  • Learn the importance of detailed construction modeling for coordination, using tools like Dynamo for efficient data exchange.
  • Grasp the significance of accurate tunnel-segment placement for service bracket installation.
  • Explore techniques for integrating site survey data into construction models for enhanced coordination.
