BIM Precise Surveying and Mapping Resolves World’s Largest Twin-Helix Steel Structure

The Meisi Lake City Island is the world’s largest twin-helix steel structure. It is very difficult to install elements onto the site precisely with traditional methods. Working with BIM 360 Glue software and Point Layout software, users can generate the set points from Building Information Modeling (BIM) models directly, laying out the data with the total station automatically. The class will show the best practice to set the points to space elements, and run the site survey with a standards procedure. We’ll also show how to get the site position with a total station, and compare the installation results with original BIM model for quality audit. The economic and social value is to eliminate deviation of manual centering, and improve mapping precision; decrease quantity of surveyors with automatic robot, improve mapping efficiency, and shorten working period; and reduce surveying works at high altitudes, and thereby improve safety management. This session features Point Layout, BIM 360 Glue, and BIM 360 Layout. AIA Approved
