TOP-DOWN SYSTEM ADVANTAGES :- High execution rate (5 underground + 5 above ground

floors at the same time)- Maximum safety for self and adjacent structures,

provided by underground structure- Easy underground floors pouring – on ground- Project management advantages – several work sites at

once- Cost efficient

TOP-DOWN SYSTEM DISADVANTAGES :- Some technical difficulties (such as: initial floor support)- Difficulties with positioning and anchoring the metal structure in foundation

-Different execution rates:- 1 underground floor 30 days- 1 superstructure floor 10 days(superstructure initiation delay)

MATERIALS Concrete - C32/40 – in core walls, between level 5 underground

and level 5 above ground- C20/25 structure remaining, pilots, cast walls, mat foundation

Hot rolled steel S 355 – M (OL52)- HD columns- W, UPN, IPN beams and other structural elements

S275 (OL37) – Hambro joistsPC52, OB37 - RebarSTNB - Wire meshConnections – welded joints for rebars & for reinforcing with

rebars of the column segment connections– bolted connectionsfor metal structure assembling

(bolts class 5.6 and hi strength bolts class. 8.8 şi class.10.9)
