How you’ll check the Centering of the Slab
Known as the TBM (Temporary benchmark level) - This Level is taken from the down.
You get the Height below which the actual Height of the centering must be decided- because, as you know, the Plywood is placed at the same level.
Measure the Plywood level to the marking (In the Image-29 Inch) and Repeat it with all the Columns and rods.
Now, with the Measuring tape, Check the level from every corner and find out that the Height from the slab centering is the same everywhere.
a. If it’s less- Tell them to get the centering up. If you find the 28 inch, rise the centering to 29 inch.
b. If it’s more- reduce the Height, let’s say if it is 30 Inch; tell the site Engineers to reduce it so make exact 29 Inch.
When Plywood is laying in Different Pieces, tap the Joints' opening in the centering.
Tapping the Joints done
a) When concrete is pouring into the Slab, Water will leak out from the holes.
b) Water cement Ratio- It plays a significant role in the slab centering checklist as it is Important to maintain the slurry's water-cement ratio. So to save the Ratio, Voids are to be filled with the Tapping.
