In this photo each stage by stage of the process can be seen; from the poured in reinforcements in the foreground and on the right side of the image, the veritcals are attached in the center, the cross grid tied in left center, and in the midground the forming walls are being tied in.
These workers are attaching the forming walls to the vertical reinforcing steel bars.
As shown in the earlier post, this is the tied steel on the ground which will be raised and set in place attaching to the verticals.
The forming walls are assembled at the site to specifications insured to provide proper support for the poured concrete.
Every detail is important.
