A plumb system for construction projects having a laser module embedded within includes a spring or the like device acting as a connecting device to a tripod or the like apparatus for projecting a vertical laser beam to a vertical end point, from the floor to a certain top point. Conversely, a spring or the like device mounted to the opposite end of the laser module of the plumb can be mounted to a certain high point for projecting a top to bottom laser beam for determining an end point at the floor. An optional horizontal base designed to horizontally receive the plumb for projecting a horizontal laser beam. A horizontal level indicator mounted onto the horizontal base can ensure a true horizontal plane. An optional self standing horizontal block can be used to determine the intermediate points of the horizontal laser beam. In addition, it can be used as a fixed point on a vertical surface by positioning the laser beam to lock on to it, the other horizontal point in line with the fixed point can be determined.
