A top mounted column placement element includes a plumb bob hanging element to allow a plumb bob to hang from the top mounted column placement element and identify a corresponding portion of a bottom mounted column placement element. The top mounted column placement element defines a column perimeter. The bottom mounted column placement element also defines a column perimeter. Once the top mounted column placement portion and bottom mounted column placement element are in place, the column can be placed and set to conform to both defined column perimeters, ensuring the column is properly positioned.

Some embodiments of the invention relate to an inclination sensor for determining an inclination of an object with respect to a reference vector of a reference coordinate system. The inclination sensor may include a tilt detector for determining gravity vector data of a local gravity vector, and a calculation unit comprising means for providing, based on the position data, position-related vertical deflection data, the vertical deflection data comprising information about a relation between the local gravity vector and the reference vector, and calculation means for calculating reference vector data based on the vertical deflection data and on the gravity vector data, wherein an inclination of the object with respect to the reference vector is derivable from the reference vector data, to a surveying system comprising such an inclination sensor and to a method for determining the inclination of the object with respect to the reference vector.

A tilt sensor includes a one-way rotational drive configured to translate rotational motion of an input shaft in a first rotational direction about a first axis of the input shaft and in a second rotational direction about the first axis into rotational movement in a first rotational direction about a second axis of an output shaft. The tilt sensor further includes a pendulum coupled to the input shaft. The pendulum is configured to rotate the input shaft in the first rotational direction or the second rotational direction responsive to a tilt motion of the tilt sensor. The tilt sensor further includes a motion meter coupled to the output shaft. The motion meter is configured to display a measure of total tilt motion of the tilt sensor.
