yes, joint measurement for laps should be recorded
if the bar length is 5o m , what will be the actual length including lap length
Lap reinforcement is needed because if lap is not given in a steel structure,that portion will be filled only with mass concrete and it will not attain the expected strength,so inorder to prevent that we can provide a lap rod whose length is 50D i.e 50 times the diameter of the rod.
when length of reinforcing bar is small and we have to provide longer reinforcement in that case the second bar is provided with proper overlapping with the first bar this overlapping is known as lap length. the straight length of shall not be less than 12mm dia and 200mm length.
