In Zweibrücken, a satellite-based GPS and a positioning zone laser transmitter from Topcon picked up the data for the VÖGELE System for 3D Machine Control. Before construction work got underway, the laser transmitter only had to be set up at a fixed point. This minimal preliminary work, which could be carried out simultaneously with the preparation of the surfaces for paving, greatly increased the time available for the job. As a result of this time saving, it was possible to build a section measuring 300m x 45m, corresponding to 13,500m2, in each night shift. In the planning, an area of only 180m had been assumed. In other words, during each night shift, a 5,400m2 larger area was built compared to the quantity calculated.
