Since the fitting accuracy of shell structures is in the centimetre range, but that of metal façade elements is in the millimetre range, façade sheets always had to be reordered and specially adapted for assembly in the past. On the construction site of the Palm paper factory, Borgel Elementbau for the first time used a 3D laser scan survey for a building element, which helps to avoid this additional effort and to shorten the assembly time.
The scanned data of the 3D model allow such an exact pre-planning that the façade cladding of the building can be executed in one “go” without any additional adjustment work. According to project manager Niels Borgel, the resulting reduction in installation time is approximately 2 weeks.
