Count reinforcing bars from spacing and cover, then estimate length, lap and steel mass. Metric mass uses d²/162 kg/m. US mass uses nominal pounds per foot for sizes #3 to #18. Lap is a multiple of the nominal diameter. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
12 mm bars at 150 mm centres over a 6 m run.
