Unit rate-based cost estimating – input and methods
Languages of publication
The paper investigates the so-called “simplified methods” of construction cost estimating: from the simplest single-rate estimates to complex elemental and feature-based cost analysis. Method databases of recorded or calculated unit rates and a wide choice of data manipulation techniques, such as intuitive or mathematically supported case-based reasoning, statistical inference and non-parametric modeling are looked at. The consequences of using input from real-life projects and uniform purpose-made calculations (such as those published in Polish pricebooks) are also analyzed.
