foundation part / flange part

ELF delivered the galvanized flange parts

today 8.10.2014 was an exciting day!  the flange parts came back from galvanizing and Andre brought it from ELF to my home.
It looked so easy how he lowered the 300kg part into the pit. Roloff-Bau (concrete work) and ELF (welding) did a perfect job. Everything is levelled.. ……perfect 10 for both !

10. Oct. 2014 – 27 cubic metres = roughly 50 tons weight

today 27cubic metres of special quick mix concrete were poured into the pit.
