Calculate crew output rates and estimate how long a task will take to complete.
500 m² of work, crew of 4, each producing 5 m²/hr, 8-hour days:
Use this for scheduling, labour planning, and progress tracking on activities like paving, forming, placing concrete, or earthworks where output rates are reasonably known.
Does not account for weather delays, equipment downtime, or learning curve on new crews. Use as a baseline estimate, then adjust based on actual site conditions.
Best source is your own historical production data from similar past work. RSMeans or similar cost guides also publish typical productivity rates by trade.
Not always — confined work spaces or limited equipment can create diminishing returns beyond a certain crew size. This calculator assumes linear scaling, which works best for open, unconstrained tasks.
