A concrete contractor historical records show that the construction duration for a cast-in-place foundation formwork is 1,000-SF/crew-day. Determine the number of days a 200,000-SF formwork for a cast-in-place concrete foundation using 3-crews.
Solution: Apply the equation: Durationactivity = Area / Productivity * Crew Size
Durationactivity = 200,000 - SF/ 1000-SF/ Crew-day * 3 crew = 66.67 days
