Steps

Work scaffolding:
The basis is formed by a work scaffold which must comprise at least two assembly frames (No. 1, Fig.
4+5). They must be aligned parallel to one another and at right angles to the wall.
The wall is measured from the work scaffold; the facade cladding is applied and the trueness of the wall
is then verified. Position the assembly frame on the scaffolding at a sufficient distance to the wall so that
after measuring the wall the facade cladding and/or ETICS can be applied without needing to move the
work scaffolding.
Attaching the measuring elements to the work scaffolding
Connect the measuring elements (No. 3, Fig. 1, 4, 5) using the brackets (No. 2, Fig. 1) to the longitudinal
beams (No. 4, Fig. 4+5) on the assembly frame. Deploy 3 measuring elements per assembly frame if pos-
sible (No. 3, Fig. 4+5).
The two upper and lower measuring elements remained fixed while the middle measuring elements are
attached at working height and moved upward as building work progresses.
Using the adjusting device (No. 5, Fig. 1), set the front side of the measuring element to a specific clea-
rance with respect to the wall to be measured (No. 6, Fig. 4).
Align the front side of the measuring element either flush with a predefined reference point on the wall, or
set up the front side at a predefined clearance to it. The reference points should be on a common reference
plane that touches the wall or maintains a specific clearance to the wall. The clearance depends on the
thickness of the facade cladding and/or ETICS.
After doing so, you can use the plumb lines (No. 7, Fig. 4+5) to measure the wall; attach the lines to the
measuring elements using the positioning grid (No. 8, Fig. 1).
Measuring the planes by means of plumb lines:
Use the positioning grid attach the plumb lines in the reference plane, or at a predefined distance from the
wall, vertically and horizontally to the aligned measuring elements (No. 7, Fig. 4+5).
The front side of each measuring element also has a central positioning grid (No. 9, Fig. 2+3), 2 inclined
positioning grids (No. 10, Fig. 2+3), or a positioning bore (No. 11, Fig. 2+3). The central positioning grid (for
horizontal alignment) and the positioning bore serve to lay a plumb line laid in them as close as possible to
the front side. Inclined positioning grids (for vertical alignment) allow you to lay plumb lines vertically with
respect to the wall to be measured near the front side.
Measure the trueness and planarity of the wall from the reference plane defined by the tensioned plumb
lines. The layout and proximity of measuring points will depend on the individual wall conditions.
If necessary, you can now level the wall. You can then apply the facade cladding or ETICS to the wall and
verify its planarity.
If possible attach the topmost and bottommost measuring elements in fixed positions on the scaffolding
and move the measuring elements in between them as building work progresses. You can use the fixed
measuring elements as a reference for the correct alignment of the measuring elements that you move,
and adjust the elements as needed.
