Step 3- Insitu Concrete Frame

Secondary steel is added in some projects for additional support to the structure or the cladding and other building elements. Normally this is designed after that of the primary structure, and is often considered during or after the primary structure construction period. Therefore it has not been included in the activity steps but has considerable additional health risks such as significant manual handling unless it is designed early enough to be included in the main frame works.
