A rotating construction laser includes a laser core module with a laser unit for emitting a laser beam and rotation means for rotating the laser beam around an axis of rotation defining a laser beam plane. The rotating construction laser is provided with an outer pivoting mechanism attached to the laser core module, the outer pivoting mechanism being operable to tilt the laser core module around an X-axis as a first axis of rotation and around a Y-axis as a second axis of rotation. The rotating construction laser further includes a dual grade mechanism with a first level sensor operable to indicate a rotation of the laser core module around the X-axis and a second level sensor operable to indicate a rotation of the laser core module around the Y-axis. Both level sensors can be operated mutually independent.
