Project Management for Construction: Cost Estimation

A nonlinear cost relationship often used in estimating the cost of a new industrial processing plant from the known cost of an existing facility of a different size is known as the exponential rule. Let y n be the known cost of an existing facility with capacity Q n, and y be the estimated cost of the new facility which has a capacity Q.

ESTIMATING COST MODELS: Power-Sizing Model. | …

Table 2-1 gives power sizing exponent values for several types of industrial facilities and equipment. The exponent given applies only to equipment within the size range specified. In Equation 2-3 equipment costs for both A and B occur at the same point in time. This equation is useful for scaling equipment costs but not for updating those costs.

Jan 16, 2014· Installation cost typically amounts to around 7–11% of the total cost of the compressor unit, but compressor size, capacity and location significantly impact the installation cost. A linear cost estimation approach can prove useful.

Scale economies and the "0.6 rule" - ScienceDirect

One aspect of scale economies which has received more attention in the engineering than in the economics literature is the "0.6 rule". This rule has its origins in the relationship between the increase in equipment cost (C) and the increase in capacity (V) given by C 1 /C 2 = (V 1 /V 2) α where α denotes the scale coefficient.A value of α less than unity implies increasing returns to scale.
