2006 _ SHEET COATING LINE - MITTAL STEEL POLAND S.A. in Swietochlowice
The design of a wide-spatial RC substructure of varied effective depth from -4.4 to -9.2m, the length of 50.5m and 4.5-14m various width

- on shallow parts of the basement it's been designed and erected the 2-storey 10.3m high RC structure which has 2 levels of the 0.8m technological floors of 11.5m free span and a bearing peripheral wall of a 0.2m thick,
- because of the various external loads and variable rigidity in longitudinal direction - the jet grout technology piles - in the proper spacing - were applied to bear this foundation,
- a concrete was poured in 8-12m sections the works have been fulfilled in urban environment during winter; besides the standard procedures, the horizontal and vertical section breaks were secured with an expansion tape (a water filtrations of the various efficiency was located on the whole excavation slope),
- watertight concrete C30/37 and the steel class A-IIIN have been adopted and the substructure was designed in order to satisfy the serviceability limit states
