RPG Transmission erected Power Transmission Lines and had great difficulty assessing the progress of the tower erection. Excel (part of MsOffice) could generate charts depicting each of the tower in any transmission path. However, they could not have a clear view of what occurred between the charts, i.e. between two towers beyond the charted range.
I was hired for creating an Excel Addin, whereby I could create charts in a different way. To give an example:
Bar Charts showed 10 Towers, say from 1 to 10, 11 to 20 and so on.
My program created Special Bar Charts, from 1 to 10, 9-19, 18 to 27 and so on.
Additionally, my program would create a Graphic, showing all Six Stages of Completion.
