Abstract

Purpose

Delay causations in infrastructure projects are well reported in normative literature. However, very little is known regarding the environment-related causations which can assist in developing mitigation strategies. This study aims to examine critical causations of overruns in marine construction projects.

Design/methodology/approach

A total of 73 delay factors, grouped into 16 themes, were identified from literature. Data relating to the significance of each factor were collected through a questionnaire survey administered to 151 respondents. A total number of 126 valid responses were retrieved. Reductionist methodology was used to identify the statistical significance of each delay causation.

Findings

All 73 variables analysed in the study are significant, including communication issues amongst stakeholders, inadequate planning, safety issues, deficient technical instructions and inappropriate management approaches. Others include design and construction issues, issues with project organisational structures, political and cultural factors, environmental uncertainties and complexity in resource management. The study also found estimation errors, owner's attitude, financial issues, delay in approval processes, construction strategies and unavailability of appropriate technologies for the work as influencing factors. These findings are consistent with earlier studies on other forms of projects, but they further confirm that they are very relevant to marine projects.

Research limitations/implications

Due to the diversity of marine projects, overrun factors are likely to manifest in different ways in varying project circumstances. In addition, economics, technologies and local legislation often influence project situations differently.

Practical implications

The implications of these findings will assist in growing the practicality of scheduling and contract administration theories in marine projects. Although delay causations that have been reported in normative literature are relevant to marine construction, however, some of the causations are more severe in marine projects. It is important that planners and project stakeholders are mindful of this such that they can develop their expectations to tolerate variability rather than trade impracticable blames.

Originality/value

Determining delay factors specific to marine construction projects assists stakeholders and project management community in developing dedicated strategies applicable in scheduling to prevent and correct obstructions caused by overruns. Since projects are different in types and sizes, delay observations cannot be generalised.

Abstract

Purpose

Teachers can be regarded as key figures in climate change education (CCE). Therefore, the purpose of this study is assessment of Iranian lower secondary teachers? level of knowledge, attitudes and practices toward CCE in a less-touched-upon context.

Design/methodology/approach

The present study used a cross-sectional survey design, which used a specially designed questionnaire administered in ten high schools (five boys’ and five girls’ lower secondary schools). A sample of 108 lower secondary school teachers was selected through a multistage stratified random sampling technique. The gender structure of the sample was 48.1 per cent male and 51.9 per cent female subjects. To determine the status of teachers’ knowledge, attitudes and practices, the obtained quantitative data were classified into three categories on a scale of 100 per cent: good status (more than 75 per cent), moderate status (50-75 per cent) and weak status (less than 50 per cent).

Findings

The findings revealed that the involved teachers were equipped with an appropriate knowledge, i.e. 22.2 per cent good and 52.8 per cent moderate levels of knowledge. Furthermore, the subjects’ level of attitude was moderate (44.5 per cent); however, their level of practice was weak (52.8 per cent). In terms of gender, male subjects’ knowledge and attitude levels were higher than those of female subjects. However, female subjects reported higher levels of practice in comparison with male subjects. Overall, the results of this study highlighted the necessity of improving lower secondary teachers’ CCE in general and of the level of their attitudes and practices in particular.

Originality/value

The present study sheds more light on the change management and environmental education within the Iranian context. The results of this study accentuate the necessity of presenting more CCE programs for teachers. Furthermore, curriculum planners can take advantage of the obtained results to carry out curriculum reforms.
