Analysis of cost and schedule performance of international development projects

This study focuses on cost and schedule issues of international development (ID) projects. Through empirical analysis we examine ID project cost and schedule performance and the main reasons for poor project outcome. We look at 100 projects that are sponsored by the Asian Development Bank and hosted by several Asian countries. The study identifies that most late projects experience cost underrun – an unusual cost and schedule variation relation in projects. Further we identify the root causes of project delay and cost underrun. Research findings will benefit ID project professionals, organizations and the ID project body of knowledge. The study can be extended to analyse other developing country projects sponsored by different donors.     

Effect of project complexity on cost and schedule performance in transportation projects

Project complexity is a contributing factor to project performance. Understanding how project complexity interacts with management actions and project performance is imperative. This study fills this knowledge gap by empirically exploring the relationship between construction project complexity and project performance and their interaction with resource allocation. Empirical data were collected from 79 transportation projects. Due to its capability to build several regression models by adding independent variables to previous models, moderated hierarchical regression analyses were conducted to identify the underlying effect of resource allocation on the project complexity and performance relationship. The results show that: (i) project complexity was significantly correlated with schedule growth (positive correlation) but not significantly correlated with cost growth; (ii) resource allocation was significantly correlated with schedule growth (negative correlation) but not with cost growth; and (iii) resource allocation had a buffering effect where increasing resource allocation significantly decreases the effect of project complexity on schedule growth. The findings from this study contribute to the extant literature on construction project complexity by empirically showing that the impact of project complexity on schedule performance interacts with the level of resource allocation. This understanding of the role of resource allocation may help construction managers and engineers to better administer and manage their complex transportation projects. The findings also imply that organizations should appropriately evaluate project complexity to allocate necessary resources to achieve project success.

The capital budgeting evaluation practices (2014) of contractors in the Hong Kong construction industry

Capital budget evaluation plays a crucial role in financial management. This places a firm in a competitive position. Recent development points to the need for implementing capital budgeting in construction organizations due to the capital-intensive nature of construction business. The aim here is to investigate the trends in the practice of capital budget evaluation among construction contractors operating in Hong Kong over a 20-year period. A longitudinal survey approach is used; four cross-sectional surveys were conducted between 1994 and 2014. The findings indicate that ‘formal financial evaluation’ is the most common technique used for capital budget evaluation. In addition, the practice of capital budget evaluation is more pronounced in the large-sized firms. A comparative analysis of the results of the four surveys reveals that there are variations in the degree and frequency of use of capital budget evaluation techniques over the study period. Further research is needed to understand the challenges associated with the use of sophisticated capital budget evaluation techniques in the construction industry of Hong Kong.

The making and impacts of a classic text in megaproject management: The case of cost overrun research

This paper presents a case study of the making and impacts of a classic text in the field of megaproject management. It focuses on Bent Flyvbjerg, Mette Skamris Holm and Søren Buhl's article Cost Underestimation in Public Works Projects: Error or Lie?, which was published in the Journal of the American Planning Association in 2002. The paper shows that classic texts can have a significant impact on megaproject planning theory and practice. Within the academy, classic texts are those that are widely cited and come to define the theoretical terrain, types of research questions that are asked and methods used in subsequent research. They also directly contribute to new megaproject planning methods and shape the public discourse on megaproject delivery. The paper concludes by identifying the key ingredients that make a classic text.     

Impact of correlation and induced correlation on the estimation of project cost of buildings

Treatment of correlation between variables is necessary for deriving any theoretical distribution of the project cost of buildings. This paper highlights some often ignored theoretical requirements necessary for a rigorous treatment of correlations. The condition for a positive definite correlation matrix is described, along with an analytical procedure and a computer program developed to verify the positive definite condition when correlation coefficients between input variables are estimated using historical data. The analytical procedure and the developed computer program can be used in any application that obtains correlation information from historical data or as subjective judgements to be used in a functional relationship. A new concept called induced correlation is suggested to define and to treat correlation between derived variables that arise from the common (shared) primary variables in their functional forms. A published numerical example is used to highlight the stages where correlation between variables can have an impact on the estimation of moments (estimated expected value and estimated standard deviation) for the project cost of buildings, and to demonstrate the improvement in the estimation of the standard deviation of project cost as a result of treating correlations in risk analysis.
