S-curve modelling in early phases of construction projects

The methodological procedure for forecasting cost distribution over time is given for the project realization phase using cost s-curves for three different types of structures: building, tunnel, and motorway. Three different approaches are used, and their results are correlated and presented in form of mathematical regression expressions and appropriate diagrams. The proposed methodology can be used for cash flow forecasting during all phases of construction projects, specially in the earliest phase in which detailed information about the project is scarce.
