Abstract: Apparatuses and methods for accurately applying an architectural layout to a surface. A calibration system includes a calibration rig having a plurality of vertical calibration legs assembled with a plurality of horizontal calibration legs and a laser that emits one or more beams of light onto a work surface to position the architectural layout relative to the calibration rig on the work surface. Calibration markers are positioned at intersections of the vertical and horizontal calibration legs for the laser to scan and confirm calibration accuracy of each of the calibration markers. The calibration markers calibrate the laser by using fixed, known points on the calibration grid that can be folded, collapsed, disassembled, and/or rolled for easy transport to other locations. The work surface can include obstacles and/or be uneven.

Abstract: The present device may project a building design drawing onto a floor to indicate substantially precisely where contractors should install their products on the construction site. The device scans the raw space, compares the proposed construction documents with the existing conditions and projects a full scale accurate image of the plan on a work surface of either gravel, dirt and/or concrete. The resulting image would allow installation of underground utilities and walls more quickly and with increased accuracy. This decreases the time needed for installation and reduces or eliminates the need for costly re-work necessitated by these common errors.
