NPV-at-Risk Method in Infrastructure Project Investment Evaluation
Author: Sudong Ye and Robert L. K. Tiong | Size: - MB | Format:PDF | Quality:Original preprint | Publisher: ASCE Journal of Construction Engineering and Management | Year: 2000 | pages: 7
Strategic capital investment decisions are crucial to a business firm. The decision to invest in privately financed infrastructure projects requires careful consideration, because they are exposed to high levels of financial, political, and market risks. The project appraisal methods should incorporate analysis of these risks. A number of capital-investment decision methods can take risks into account, but each of them focuses on different factors and has its limitations. Thus, a more vigorous method is needed. A systematic classification of existing evaluation methods shows that it is possible to develop a new method—the net-present-value-at-risk (NPV-at-risk) method—by combining the weighted average cost of capital and dual risk-return methods. The evaluation of two hypothetical power projects shows that the NPV-at-risk method can provide a better decision for risk evaluation of, and investment in, privately financed infrastructure projects.

BS ISO 11277 specifies a basic method of determining the particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction.
BS ISO 11277 has been developed largely for use in the field of environmental science, and its use in geotechnical investigations is something for which professional advice might be required.
A major objective of BS ISO 11277 is the determination of enough size fractions to enable the construction of a reliable particle-size-distribution curve.
BS ISO 11277 does not apply to the determination of the particle size distribution of the organic components of soil, i.e. the more or less fragile, partially decomposed, remains of plants and animals. It is also realized that the chemical pretreatments and mechanical handling stages in BS ISO 11277 could cause disintegration of weakly cohesive particles that, from field inspection, might be regarded as primary particles, even though such primary particles could be better described as aggregates. If such disintegration is undesirable, then BS ISO 11277 is not used for the determination of the particle size distribution of such weakly cohesive materials.
