The invention relates to a construction laser system comprising at least one rotation laser which has a laser unit and a rotatable deflection means and is intended to emit a rotating laser beam, wherein the rotating laser beam defines a reference surface, and a laser receiver for determining a position relative to the reference surface. In this case, the laser receiver has a laser beam detector which is designed to generate an output signal when the laser beam impinges on the laser beam detector. An evaluation unit for determining the position of the laser receiver relative to the reference surface and an indicator for the determined position, in particular for indicating whether the laser receiver exactly coincides with the reference surface, are also present. The invention is characterized by a controller for the laser unit, which controller is designed in such a manner that a known emission pattern is generated over a sequence of a plurality of revolutions by varying the emission of the laser beam in a manner temporally coupled to the revolution period of the deflection means, and by the fact that the evaluation unit is designed to identify the reference surface using a sequence of output signals which are each generated by the laser beam detector when the rotating laser beam repeatedly successively impinges, which sequence corresponds to the known emission pattern.
