What is the tolerance for compression test results of concrete, according to the standards?
This is the wrong method of lapping rebars in the column. The lapping length of the rebar must be 46d. For 16mm bar, =16 x 48 =768mm The lapping shall be shattered and not in one place. And the welding must be done for the whole 768mm on both sides.
