Week – 5 Estimating Duration Work Problem >>> Construction Project Management
1. Assume that you are a construction manager of a general contractor company. Your company is awarded to construct a residential tower in upper Manhattan in New York City. The building is affected by space congestion on 2 sides of the building and other 2 sides are congestion-free. The formwork for the building started on April 1, 2019. You are assigned to calculate the duration of formwork activity using the following data :
- The construction team has a 4 formwork crews with 3 members each for the whole building.
- RS Means Productivity for congestion-free sides = 470 square feet per day per crew member.
- RS Means Productivity for congested sides = 390 square feet per day per crew member.
- Formwork required on each side of the building = 56000 square feet.
1. What is the total formwork required for the building? ( in square feet).

- RS Means productivity for congestion-free sides = 630 square feet per day per crew member.
