urgent feedback required pls

[Elhani]

hello sir,
we are also constructing our house, we have finished the plinth level and soil filling and the concrete laying is done hes starting the pillar to reach lintel level, but our contractor is doing the pillar concrete filling work manually (in the sense hes not using centering guys and gang machine) hes just starting with 4 pillars and then move to the others (remaining 8 as we have 12 pillars)
i wanted to know if the work for pillars is done together by centering guys and concrete filling thru gang machine? or manually like how our contractor is doing!
pls give feedback ASAP, thanks

Centering will come into picture for Lintels ,Beam and Roof Slab. All Columns must be cast up to lintel level , before the shuttering work can begin.
You can cast 12 columns at once with 12 Column Boxes and Lot of labour and gang or do one by one with manual mixing .Its fine your contractor chose to do 4 at a time.
