Abstract
A scheduled progress curve should be smooth without any unevenness, and the amount of work in the middle of construction period should be more than that in the earlier or later period. The curve showing labours for the construction of 4-story reinforced concrete building with the total area of 4000m^2 is in general as shown in Fig. 2 by the solid line, whereas it is desirable that the curve takes a form as shown by dotted line. If the period of construction could be shortened, for instance, by 5 days in concrete work, by 10 days in carpenter work and by 10 days in plastering work, the curve would be moved towards the desired form shown in Fig. 4. The amount of work will be further improved if the minimum amount of materials required by the labours is added, and the scheduled progress curve will approach the ideal form.
