Reply #345: Drawing

[Kevin Fenton]

"So, after the building is constructed, when they do an inspection report someone draws in and numbers 47 core columns, labeling two such columns CORE COLUMN (TYP) because they just thought that's how the building was constructed?"
Yes. The symbols on the diagram and the legend indicate that the columns labelled CORE COLUMN (TYP) were not the ones which were inspected. The vast majority of core columns were not inspected in this inspection. Therefore the drafter must have taken their layout from somewhere else, presumably some preceding documentation.

"Do you think that the person that drew this diagram just made up the layout and numbering of the vertical columns in the building?"
No, he/she/they got it from somewhere else and allegedly verified a small proportion of it. As we don't know who drafted it and don't know what preceding documentation he/she/they based it on, then we cannot verify the accuracy of the drawing regarding the core columns. As an argument, it's only a little better than, "I remember this documentary I saw..."

The photo of the steel core columns during construction is much better, so is the "bathtub" photo. Not so sure about "sunset" though.


Why do you think it's the bottom of the core?
