Profile boards

Once the layer of blinding has been completed, the profile boards are set up. The main grid lines or outside faces of the structural shell are established with wires and bricks. The setting-out is the responsibility of the architect and is subsequently checked by the surveyor. By that, he or she refers once again to the existing permanent control points. The surveyor marks the building lines on the profile boards (tolerance ±5 mm). With the help of plumb bobs the plan layout is projected onto the blinding layer of lean concrete. The location of the building is thus fixed. Work can now begin on the drains or the ground slab.
