A concrete panel pre-pour marking system in the form of a portable stand that includes a central reference pointer at the bottom end of the stand that is used as a starting point. The upper end of the stand has a computer processor, keypad, display screen and a device for reading pre-saved construction drawings for the panels to be formed. Key points for locating panel corners, arches, lift inserts, reveals, openings, and other required features are identified with a projection of laser beam(s) to the specific point on the surface upon which the forms are to be laid out and the concrete to be poured.
