- PurposeThe purpose of this paper is to explore the impact that cost overruns and time delays exert on large public construction projects to clarify how past and current research regard factors causing cost overruns and time delays in large public construction projects.Design/methodology/approachThis paper, which is based on an analysis of a literature selection consisting of 40 journal articles, investigates and ranks the occurrence of and the explanations for cost overruns and time delays in large public construction projects. The study makes use of a kiviat diagram/radar chart in order to visualize multivariate data.FindingsAggregated rankings of important causes of cost overruns and time delays are reported. These show a strong emphasis on the management aspect as a primary cause of cost overruns and delays. Additionally, there seems to be a trend toward deemphasizing the role of financial considerations in explaining cost overruns and delays. It is argued that there needs to be a more rigorous assessment of the impact that each factor has on cost increases and delays based on factual observed data as opposed to retrospective accounts from questionnaire respondents.Research limitations/implicationsOnly public construction projects have been considered. The results will not be directly applicable to privately funded construction projects and/or projects of a smaller size.Originality/valueThe use of trend data, as illustrated in a kiviat diagram, showing how different ranking factors causing cost overruns and time delays has changed in importance over time.

Konferensbidrag (refereegranskat)abstract
- In construction-related education, leadership development is generally a scarce feature in education curricula. Yet, the critical need of "good" leadership at all levels of construction-related organisations is being increasingly highlighted in research and in practice. In this paper, we focus on how leadership competence at middle-manager level, e.g. site managers, may be enhanced and we examine how higher education may address this need. The overall aim is to suggest how leadership development may be introduced and/or improved in programs and courses. Rather than using a questionnaire or individual interviews, the data was collected in three focus groups. Each group addressed one level of higher education: vocational, bachelor and master, respectively, and included practitioner, teacher and student stakeholders. The focus groups were recorded. The field notes and the photographic documentation strengthened the reliability of our interpretations. The paper describes how focus groups were used, discusses the aggregated findings from the groups and suggests some ways in which education curricula can be improved to incorporate transferable leadership development and competence to contexts in which graduates will operate.
