The labor productivity of constructing a 1250 square feet concrete block wall by two bricklayers and three helpers in four days, working 8 hours a day, is approximately 0.128 worker-hours per square foot.
To calculate labor productivity, we use the formula:
Labor Productivity = Total Labor Hours divided by Quantity of Output.
In this case, the total labor hours are the combined hours worked by the two bricklayers and three helpers for four days at 8 hours per day. The quantity of output is the wall area, which is 1250 square feet.
Total Labor Hours = (2 bricklayers + 3 helpers) times (4 days) times (8 hours per day). Total Labor Hours = 5 workers times 4 days times 8 hours per day equals 160 worker-hours.
Now, plug this into the labor productivity formula: Labor Productivity = 160 worker-hours divided by 1250 square feet. Labor Productivity is approximately 0.128 worker-hours per square foot.
So, the labor productivity achieved on this wall is approximately 0.128 worker-hours per square foot.
The question probable may be:
1. A concrete block wall is 1250 square feet (sf) in wall area. Two bricklayers and three helpers built this wall in four days, working 8 hours a day. Calculate the labour productivity that was achieved on this wall. Remember the units of labour productivity are labour hours (workerhours) per unit of quantity (square feet, in this case)
