This is a client requirement. The clients would like to have the erection drawings in DWG format as well.
Why do they need them? They require the DWG format for the erection drawings because they use them to mark the drilling locations for anchors and determine the precise placement of columns, among other purposes. How do they do this?:
The more sophisticated ones use Total Station Surveys. Look through some videos on this:
- How to level a total station?
- How to import dxf into total station software?
- How to mark out points via total station.
Be warned: there is a risk that surveyors may use outdated or obsolete files in order to mark out column locations, drilling points. (I have a software solution for this problem, which will come shortly). Till that time, remain vigilant in ensuring your clients have the latest drawings.
On a related point: it is critical that we do not miss any dimensions. If we miss a dimension, we will get a call from the construction site, or the factory floor: the time wasted, and the costs are astronomical.
