Short answer first, detail after

Construction's recurring confusions, settled once and for all

DXF or DWG, habitable area or statutory area, schedule of rates or bill of quantities. Questions people retype every year, whose answer fits in three lines.

These pages sell nothing. They exist because the wrong definition is expensive: an area quoted under the wrong rule gets disputed, a file sent in the wrong format comes back the next day. FloorScan only appears at the bottom, where the tool actually relates to the question.
