At 02:36 we have welding of the WTC perimeter columns. You need approx 2-3 full time welders on each tower do do this, so it is not very expensive. The concrete floors are at 11:50. Casting on-site also produce flat floors with no bending, that actually occurs on the steel underneath. Note that the steel lattice get cast together by the concrete.
This was included in material given to Tom Alandh at SVT in September 2008.
