This study assessed the critical success factors (CSFs) of public-sector road construction projects execution from the perspective of definitive stakeholders associated with such projects by drawing on in-depth semi-structured interviews (16) and surveys (372) in Ghana, thirty-four (34) CSFs were identified. Using Relative Importance Index (RII), Spearman Rank Correlation Coefficients, and Kendall’s Coefficient of Concordance and the Chi-square test of significance statistics, the top ten most important factors in descending order are: the absence of political interference, project continuity by successive governments, adequate project funding, support from financial institutions and donor agencies and countries, government commitment to the project, absence of clientelism, absence of nepotism, no political corruption, payments of contractors on time and absence of court injunction or legal suit and land litigations. This study contributes to road construction CSFs in the context of public sector road construction in developing economies.

Government construction projects are vital to the economic development of developing countries. However, although most of these projects suffer from abandonment, little evidence exists concerning the causes that account for this setback. This paper investigates the causes of government construction project abandonment in Ghana. We used a sequential data collection approach, in-depth semi-structured interviews, and questionnaire surveys to solicit the views of project management practitioners, contractors, and clients associated with Ghana government construction project implementation. Using factor analysis and structural equation modelling, we find that Ghanaian government construction project abandonment is influenced by five sets of causes: political leadership, culture, external forces, resources (including funding) and administrative/institutional bottlenecks. Three of these sets of causes – political leadership, cultural and external forces, are the primary causes, while resources (including funding) and administrative/institutional causes are secondary causes.
