The first step should be checking drawing. One must have adequate knowledge for analyzing a rebar drawing. The field engineers should have proper knowledge & capability to communicate with it in the jobsite.
To become an efficient rebar checker, practice for reading drawings on a regular basis. For this purpose one should gather proper knowledge with the steel rebar binding process. Given below, some useful tricks provided by some top peers who have lots of experience in this field :-
It is suggested to carry a measuring tape with yourself all the times for the purpose of examining the spacing and the splice or development length.
One should have clear conception on physical features of the construction component i.e. if some type of drainage pipe or electrical conduit should be set up or water stopper should be substituted or any other pipes / implanted item should be arranged.
Initially, the diameter of rebar should be examined properly through a vernier caliper. The other important things which should be examined thoroughly are rebar spacing, rebar development length, lap / splice length, alignment, no sag or buckling present in the bars, the couplers should be perfectly set and tightened, bars should be perfectly fixed, there should not be any rust on the bars, check for proper clear cover, no of bars should be computed properly and be similar with the drawings and should not be under or over 2 bars which are arranged there.
