You replace them with the correct length bars, and hope never to make the same mistake again.
40 x diameter (12mm) of bars = 480mm
At what length lapping is to be provided
Lap length is the length overlap of bars tied to extend the reinforcement length.. Lap length about 50 times the diameter of the bar is considered safe. Laps of neighboring bar lengths should be staggered and should not be provided at one level/line. At one cross section, a maximum of 50% bars should be lapped.In case, required lap length is not available at junction because of space and other constraints, bars can be joined with couplers or welded (with correct choice of method of welding).
The lap length for welding a reinforced bar will depend on the size of the bar that is being welded. If the bars are different diameters when lapped, the lap length should be calculated using the lesser diameter.
Over lap of steel bar is provided 60 times of dia of steel bar. For example (.5") dia steel bar overlap length is (30"). (.5x60=30")
Lap 12mm steel bars refer to the practice of overlapping or joining two steel reinforcement bars (rebar) that are each 12 millimeters in diameter. This technique is commonly used in construction to ensure structural integrity and continuity in reinforced concrete structures, especially when the length of a single bar is insufficient. The overlapping section, or lap length, is critical for ensuring effective load transfer between the bars. Proper lapping techniques help prevent issues such as cracking or structural failure in concrete elements.

This is the additional length of steel of one structure required to be inserted in other at the junction. For example, main bars of beam in column at beam column junction, column bars in footing etc. The length requirement is similar to the lap length mentioned in previous question or as per the design instructions.
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.

The length of a lap in a footrace is 400 meters. I should know I run it.
no a lap is down and back
