According to the deformation and movement requirements of the FAST reflector, a multipurpose analysis, including the load-bearing behavior, deformation, construction costs of the reflector supporting structure and its model, is presented in this paper. The advantages and disadvantages of steel and aluminum alloy structures are also discussed and compared through detailed design calculations und...

Brazil's Tucuruí Dam provides valuable lessons for improving decision-making on major public works in Amazonia and elsewhere. Together with social impacts, which were reviewed in a companion paper, the project's environmental costs are substantial. Monetary costs include costs of construction and maintenance and opportunity costs of natural resources (such as timber) and of the money invested b...

An integrated life-cycle assessment and life-cycle cost analysis model was developed and applied to enhance the sustainability of concrete bridge infrastructure. The objective of this model is to compare alternative bridge deck designs from a sustainability perspective that accounts for total life-cycle costs including agency, user, and environmental costs. A conventional concrete bridge deck a...

In according to quantity of various consumption materials in construction sites of complex projects such as oil industry, infrastructure, and large scale commercial, management and monitoring of materials can affect on the final time and cost of project’s activities. In today’s world of rising labor costs and labor shortages, automated materials tracking can provide some advantage to impr...

Background: Occupational accidents represent one of the major problems in developing and developed countries. Deaths caused by occupational accidents result in loss of life, lost working hours, and related costs. These accidents create a lot of waste for the community and labor organizations. Moreover, they result in socioeconomic losses such as disability, loss of work time, and increased medi...

Article history: Received 8.5.2012. Received in revised form 16.7.2012. Accepted 20.7.2012. In medium voltage optimal power distribution network routing, especially in the suburban and rural ones, it is often necessary to estimate additional construction costs of tie feeders enabling backup supply in comparison with a decrease in energy not supplied costs. This paper describes one fast approxim...

Klegeris et al. (2013) are to be congratulated for adding another important piece to our knowledge of how problembased learning (PBL) can be implemented. As the debate about PBL is less about whether it works and more about what forms of it work, studies such as this will become more important. However, the authors miss one vital outcome measure of the research—that of cost. One of the major cr...
