These are some drafting samples to demonstrate my ability to present construction documents accurately and easy to understand. The most valuable feature of construction documents is to communicate properly in order to avoid mass numbers of request for information (RFIs) or, in worst cases, misleading people on the field to do the wrong thing. I took the liberty, in some cases to create, in addition to the drawing itself, some graphical clues like keymaps and diagrams which I thing convey the idea an extra step.
