Abstract

The present invention relates to a construction tool for laying out components of a structure. The system comprises a length of tape comprising a first calibrated edge and a second calibrated edge separated by a width sufficient in size so that said first and second calibrated edges remain visible after installation of the components of the structure; a plurality of stud placement indicators marked on said length of tape at periodic intervals; a leader depending from a zero line of the first and second calibrated edges, said leader comprising a length and a plurality of graduated lines indicating the length of the leader; an adhesive backing; and at least one overlay label connectable to the length of tape and comprising a length sufficient in size so that a symbolic indicator will remain visible after installation of the components of the structure, a width substantially equivalent in size to a dimension of a component of the structure, an adhesive backing, and a symbolic indicator for placement of a component of the structure; said symbolic indicator comprising an architectural symbol representing the component of the structure. The system allows tradesmen to locate (and avoid) other components of the structure after the surfacing component has been installed and the walls enclosed, for purposes of repair or later component installation. The device solves the need for re-measurement of dimensions of the structure. The device is further used in a novel method for laying out structures comprising at least one wall.
