Strategies in environmental education

The causes of environmental changes, including climate, are neither fully understood nor identified, nor do scientists agree about their nature. Yet, their impact is such that action cannot be delayed. This involves spreading public awareness through environmental education and sensitization. Hence a need to reach, to educate the poorly informed public at large. With the classroom as the base, “town meetings” and eco‐tourism may constitute potentially useful approaches towards that goal.     

Climate change: the views of forestry students in a Greek university

The trend to global warming is one of the most important problems of our time. This paper reports the findings of self‐management questionnaires, in regard to views held on the issue of climate change by the students of the Department of Forestry and Management of the Environment and Natural Resources of the Democritus University of Thrace.     

Monte Carlo simulation of construction costs using subjective data

The objectives of construction projects, from the client's point of view, are well known, and techniques have been developed to help practitioners achieve them. Ensuring that projects contribute towards protecting the environment is not yet one of these objectives. However, in almost all countries, issues relating to the environment are receiving attention from governments, non-governmental institutions and commercial organizations in most sectors of the economy, as well as from the general public. Statutory measures are being taken by governments to effect pollution control, resource conservation and protection of natural ecosystems. Productive enterprises are reviewing, and where necessary, changing aspects of their operations to address these concerns and comply with the increasingly more stringent requirements. Many environment-related statutes, regulations, codes and general policies have implications for the construction industry, affecting where constructed items are located, how they are planned and designed, the materials and components used, the techniques and equipment adopted, and how the completed facilities are maintained, altered and, ultimately, demolished.

After giving an overview of the factors contributing to, and the nature of, general developments relating to the environment {especially in the area of government policy), the implications of these trends for the construction industry are considered. Actions being taken by the industry in these regards are next discussed. It is suggested that the consideration of issues relating to the environment should be part of the culture of the construction industry everywhere, and that there is a case for making the environment the fourth client objective on construction projects.     

Effective construction planning

This paper examines the relationships between construction planning efforts and construction planning effectiveness. The influence of the project's environment and organizational characteristics of construction firms on planning efforts and planning effectiveness is also investigated. A sample of 26 building projects was studied and the results were analysed using simple correlations. Three factors were found to have a significant effect on improving construction planning effectiveness: increases in planning time prior to commencement of work on site, the extent to which emphasis is placed on the determination of construction methods during construction planning and the frequency of revision of construction plans after commencement of work on site. Significant relationships were also found between project environment variables and organizational characteristics of construction firms and planning efforts and planning effectiveness. Implications of the results are that construction planners should systematically evaluate alternative plans, sufficient time should be allowed for proper planning, thorough reviews are needed whilst work is in progress, the planning effort needs to be relevant to the environmental context of the project and the firm should be appropriately organized. Suggestions are given for future research studies.     

Predicting construction firm performance: an empirical assessment of the differential impact between industry‐ and firm‐specific factors

It is obvious that the performance of firms hinges upon the dynamics of both industry‐ and firm‐specific factors. A less obvious, and perhaps a more important, line of inquiry is that to the extent that they have a bearing on firm performance, how much do these two groups of factors respectively predict firm performance? To date, performance differences among construction firms that stem from industry‐ and firm‐specific differential effect has remained largely unexplored. Using a dataset comprising 526 firms across various construction‐related sectors, the sector‐by‐sector firm performance variation that is attributable to the heterogeneity of both industry‐ and firm‐specific characteristics was empirically examined. That statistically significant results of different effect sizes are found indicates that although these factors are often assumed to be intertwined it is possible to study their respective impact on firm performance. Future studies could usefully replicate and extend this study to construction firms in other countries to further investigate what drives firm performance under different national, industry and firm contexts.
