The purpose of this paper is to investigate the causes of road construction delays in Ghana and identify appropriate mitigation measures.
The initial approach involved an empirical analysis of 48 road projects to quantify the extent of time. This was followed by a survey of the perception of road agency and donor partner officials of the critical causes of road project delays.
About 70 per cent of road projects experience delays and 52 per cent experience cost overruns. The average time overrun and cost overruns of road projects in Ghana was 17 months and US$1.15m (or 22.5 per cent), respectively. The five most critical causes of road construction delays were delay in finance and payment of completed work by owner (client-related); inadequate contractor experience (contractor-related); changes in scope by the owner during construction (client-related); delay to furnish and deliver the site to the contractor (client-related); and inflexible funding allocation for project items (donor-related).
The most critical constraint of this study is the fact that findings are based on only the views of industry professional experts. It may be assumed that despite using broadly used terminology to refer to the causes of project delays, the interpretations by respondents may have differed from those intended. Further research could look at the correlation between time overrun and cost overrun using principle component analysis.
The identified delay factors are not unique to the road sector. From both academic and practical perspectives, the results emphasizes on the need for a holistic and integrated risk management model for the entire construction industry in Ghana.
The paper examined the causes of road project delays in the Ghanaian context and recommended remedial measures.
