A construction element (2, 42) made from two concrete slabs (4, 6, 44, 46) with a space in-between offers a simple way of placing a floor or wall in a building under construction. The space between the concrete slabs (4, 6, 44, 46) is accessible through openings between concrete slabs (4, 6, 44, 46) placed next to one another. Conduits and pipes (30) can be installed in the space. The openings between the concrete slabs (4, 6, 44, 46) are covered by covering panels (26) in such a manner that an even floor or wall is created. <??>Once the construction of the building is completed, the conduits and pipes (30) can easily be accessed by removing the covering panels (26) and can be repaired or new conduits (30) can be installed. <IMAGE>
