Costs, benefits and risks of IT in construction

Construction organisations were found to be reluctant to invest in IT due to the lack of a technique that accurately assesses the costs, benefits and risks. More importantly the associated indirect costs that are often overlooked can constitute up to 80% of costs related to investing in IT.

Costs of Silver Gulls Larus novaehollandiae in an urban environment

Silver Gull economic impacts were evaluated during 1998 to 2003 in the Greater Melbourne area. Roof nesting and roosting created substantial problems. Annual cost for cleaning, maintenance, damage, repairs and mitigation was $3,570,000. Roof corrosion was $0.9 million. Reducing anthropogenic food availability is the key to reducing problems.

Remedying discrimination : the limits of the law and the need for a systemic approach

Very few discrimination complaints reach the courts each year. As with other civil litigation, the reasons for this include the cost of pursuing litigation and, particularly for complainants, the risk of losing or receiving less than the complainant could have negotiated prior.

Drawing on interviews with lawyers and non-legal advocates in Victoria and an analysis of successful cases in three jurisdictions, this article examines the remedy the court is likely to award in a successful discrimination complaint and considers the effect of this on the eradication of discrimination in society. A comprehensive examination of the remedies awarded in successful discrimination complaints in Victoria over a three year period shows that courts are most likely to order compensation at modest amounts and complainants are not regularly awarded their costs. A comparison with Queensland and the federal system reveals a similar experience. Even in those jurisdictions where wider remedies are available, courts rarely take the opportunity to make broad orders which could affect other similarly situated individuals or deter would-be respondents.

While it is necessary to remedy the complainant’s experience, it is also necessary to address broader, systemic discrimination and a compensation award cannot do this. Remedying discrimination with compensation is primarily a problem because it is reactive. Compensation does not address other instances of discrimination in society or achieve systemic change nor does it encourage compliance because the respondent is not required to take anticipatory action to prevent another complaint.

Based on the interpretive principles and extensive remedies provided in South Africa’s recent anti-discrimination and a study of remedies ordered by the South African Equality Courts and the Irish Equality Tribunal, the article proposes reforms to Australia’s anti-discrimination legislation to enable courts to make wider orders which target other instances of discrimination in addition to remedying the complainant’s experience.

Height and construction costs of residential high-rise buildings in Shanghai

A widely recognized theme of construction economics suggests that the cost of construction per square meter increases as building height rises. However, over a number of years, research conducted regarding the height and cost issue has established a classic relationship between the two factors which can be represented by a U-shaped curve. This paper describes the study of the height-cost relationship of high-rise residential buildings in Shanghai in terms of the total construction cost and elemental costs while considering the context and commonality of buildings. This research was developed as an extension of the previous work, which examined data for buildings in Hong Kong. Initial findings indicate that the curves illustrating the relationships between height and cost of residential buildings in Shanghai and Hong Kong exhibit different profiles. The dissimilarities indicate that different sets of criteria should be applied in the judgment of height that affects cost in different locations. In terms of elemental costs, the findings suggest that there are differences in the way these costs react to changes in the building height.

The economic burden of ill health due to diet, physical inactivity, smoking, alcohol and obesity in the UK : an update to 2006-07 NHS costs

Background: Estimates of the economic cost of risk factors for chronic disease to the NHS provide evidence for prioritization of resources for prevention and public health. Previous comparable estimates of the economic costs of poor diet, physical inactivity, smoking, alcohol and overweight/obesity were based on economic data from 1992–93.

Methods: Diseases associated with poor diet, physical inactivity, smoking, alcohol and overweight/obesity were identified. Risk factor-specific population attributable fractions for these diseases were applied to disease-specific estimates of the economic cost to the NHS in the UK in 2006–07.

Results: In 2006–07, poor diet-related ill health cost the NHS in the UK £5.8 billion. The cost of physical inactivity was £0.9 billion. Smoking cost was £3.3 billion, alcohol cost £3.3 billion, overweight and obesity cost £5.1 billion.

Conclusion: The estimates of the economic cost of risk factors for chronic disease presented here are based on recent financial data and are directly comparable. They suggest that poor diet is a behavioural risk factor that has the highest impact on the budget of the NHS, followed by alcohol consumption, smoking and physical inactivity.

Analysing the relationship between new housing supply and residential construction costs with the regional heterogeneities

New housing supply in Australia has been experiencing a low rate of increase in conjunction with a dramatic increase in residential construction costs since the 1990s. This study aims to estimate the relationship between new housing supply and residential construction costs with the regional heterogeneities. Based on a panel error correction model, it can be identified that there is a causal link as well as a significant correlation between new housing supply and construction costs in the Australian sub-national housing construction markets. The model developed in this research assists policy makers to better understand the nature of the supply side of the housing sector and then enact appropriate policies to improve the new housing supply in Australia.

New housing supply and residential construction costs in Australia : a panel ECM approach

The supply of new housing in Australia has been experiencing a low increase rate since the 1990s in conjunction with an increasingly strong housing demand. On the contrary, residential construction costs across Australia?s states maintained dramatic increases simultaneously. Economic theory suggests that new housing supply is correlated to the costs of residential constructions. However, few empirical studies have focused on examining this relationship for Australian housing markets. To comprehensively investigate the relationship between the supply of new housing and residential construction costs a function for new housing supply considering the effects of regional heterogeneities is introduced in this study. By estimating a panel error correction model (ECM) applicable for quantifying the correlation with regional heterogeneities, this research identifies that a causal link and a strong correlation exist in between new housing supply and residential construction costs in Australia.
