The idea was to erect a monument of large blocks. Since concrete for Mies not "EDEL" appeared enough he took Oldenburg clinker. (It should really be first basalt blocks - but too expensive.) So a model of cooperating sculptor was made in clay (d name escapes me [Herbert Garbe].) - And with plenty of dislodgement and improvements to a coal Sketch [5] of Mies along with it! According to the model, I made the drawings, the rear mirror set was the front. E. Walter made drawings of the concrete form without the clinker panel that called on all sides minus about 13 or even with ties 25 cm (clinker Mass). There was a shell of concrete. When shuttering rods were especially carefully for the lower surfaces of the so-called blocks located at all corners and ends. This is followed by the clinker held in the joints (about 2-3 blocks) fixed so as not to fall off.
