BIM Data Management to Field Setout


   02 Dec, 2020      1:00 PM AEDT        


Presented by Graham Wirth, this presentation explores the difficulties surveyors can experience when setting out Design solid models. Initially, designs using BIM or solid modelling were restricted to building structures. This format is now becoming the norm across most structural infrastructure designs. Surveyors' traditional use of line and point positioning technologies needed new methods to manage setout of solid design models.

This presentation will demonstrate new digital tools that assist surveyors with this process. Using the IFC BIM data exchange format, surveyors are able to import Solid models traditionally referenced at a 0,0,0 coordinate location. We'll also explore converstion to metres and using 2D and 3D transformations to bring the model into a real world geodetic position, as used by surveyors. With the IFC format ability, surveyors can separate the structure elements critical to setout requirements, such as footings, slabs and columns. These solid elements are then able to be broken down to the points and lines for setout.
