Creation of a column and beams and increase the ground floor height

I want to create a column and beams for this tower, and this is how it looks in Graphisoft ArchiCAD.

Find the attached file below
ArchiCAD and Grasshopper Design.gh (59.5 KB)
And I don’t know if it is possible to increase the ground floor height to 5000mm.
Making it two things you are going to solve for me;
(1) Columns and Beams
(2) The ground floor height
Or you can choose anyone you think you can do out of the two or if there is anyone you direct me to, you can please do that for me please, Thanks.
