Time-cost relationship for predicting construction duration

Czarnigowska, A. / Sobotka, A.

Reliable estimates of project cost and duration are necessary inputs for decision-making in the earliest stages of construction projects. As little data is available, the estimates can only rest upon records of similar completed schemes. The tools that use such records to facilitate project planning continue to be the object of interest of researchers. This paper investigates the applicability of a simple regression model for the prediction of road construction duration on the basis of early cost estimates. Statistical validity of the model was confirmed, and its predictive ability tested.
