“…Corrupt consultants request different gratifications from contractors that end up reducing contractors' profit margin or leading to a loss. Results from this study amplify the call for enforcement of public procurement guidelines in public projects (Zadawa et al, 2018). A significant relationship exists between the design and management risk centre and PRIC (b = 0.306).…”

Purpose Globally, road projects are notorious for riskiness, which often results in cost overruns. In developing countries, these risks are amplified by economic instabilities and institutional failures. Majority of road projects in these countries are awarded to notedly inept indigenous contractors. Currently, research on the relationship between risks and cost performance of road projects has predominantly focussed on the client’s perspective. Effects of risks on contractors’ cost performance (profit) are inadequately investigated in literature. The purpose of this paper is to determine the relationship between direct risks and cost performance of road projects by indigenous contractors of developing countries from the contractors’ perspective. Design/methodology/approach The multivariate structural equation modelling technique was used to analyse purposively obtained data from indigenous contractors that recently completed road projects in Nigeria. Findings It was observed that a significant positive relationship exists between the aggregate project risk, i.e. project risk index of cost (PRIC) and cost performance of the projects. Significant positive relationships were also found to exist between identified cost risk centres and PRIC and between risk factors and cost risk centres. The risk centre site environment and location contributes the most to PRIC. Research limitations/implications Indigenous contractors of developing countries are to analyse the identified risk factors and centres prior to bidding for road projects and carefully manage them during project execution. Originality/value Future studies of risks in road project should aim to obtain project risk indices of costs for the projects.

The validation involved rewording to avoid ambiguous statements (Zadawa et al, 2018). Smart-PLS3 software with PLS algorithms option was performed to obtain measurement indicators.…”

“…A lack of compliance in public procurement affects transparency and accountability and leads to failing public construction projects, for example, in Nigeria (Zadawa et al, 2018), Gaza strip (Tayeh et al, 2018) and the UK (Gledson et al, 2018). In Australia, when comparing the public with the private sector, Kling (2008) suggested that the private sector leads to efficient and less costly procurement practices.…”

Purpose The propose of this study is to focus on the mediating role of compliance with procurement regulatory frameworks in implementing public road construction projects. Design/methodology/approach A cross-sectional research design was adopted. Structured questionnaires were developed in a three-step process including generating items, purifying measurement items and validating measurement items. Variables were anchored on a five-point Likert scale because it is an efficient unidimensional scale that ensures all items measure the same thing and widely applicable in construction research. Findings The findings show that compliance with a public procurement regulatory framework significantly mediates the relationship between familiarity with a public procurement regulatory framework, monitoring activities, sanction on staff and contractors’ resistance to non-compliance and public road construction project success. However, compliance with a public procurement regulatory framework does not mediate the relationship between the professionalism of staff and perceived inefficiency with public road construction projects’ success. Research limitations/implications Limited mediation studies and examples in the public road construction subsector affected this study to comprehensively investigate and compare study findings. Furthermore, the study adopted a cross-sectional research design that limits responses to one point in time. Finally, the study missed out other participants in different organizations and departments that could have had relevant information. Social implications The study contributes to public procurement and construction management research fields by uncovering this strong mediating role of compliance with a public procurement regulatory framework that collectively would help the government to implement public road construction projects successfully. Because no single factor can reliably attain objectives, blending these factors through a hybrid governance system would enable the government to achieve value for money, increase the quality and quantity of paved roads and save funds that can be channeled to other priority sectors for economic development. Originality/value Despite scholarly efforts to establish project success factors, studies have been limited to factors directly impacting the project success without considering a mediating effect among the factors that affect the success of these projects.

“…These challenges impact project performance, often with cascading effects on other projects. Researchers have reported examples of performance problems due to issues with cost and time in projects in different countries, for example, in Australia [8], Nigeria [9], Gaza Strip [4], UK [10], Ghana [11], and Kenya [12].…”

Key Success Factors and Their Impact on the Performance of Construction Projects: Case in Qatar

View full text Add to dashboard Cite

The success of a construction project depends on different factors, the knowledge of the project managers, and the type of project being developed. In this paper, based on a review of the literature, 23 factors are identified as critical and they are grouped into top-management support, project manager’s skills, project team skills, and stakeholder-management knowledge. A framework with 23 hypotheses is developed to assess the relation between these factors and project performance. The analysis of the framework is conducted based on the responses obtained from a survey of 266 engineers working on construction projects in Qatar. The results show a positive relationship between critical success factors and project performance. The highest positive perception is shown for stakeholder engagement by the top management (mean = 5.589 ± 0.582) and the lowest positive perception for the need to predict stakeholder influence (mean = 3.939 ± 0.852). The analysis of the relative importance of these factors shows that the top-management support category is ranked highest for the success of a project. Although the perceptions are based on Qatar’s study, the success factors, their relationship with project success criteria, and project performance are global; therefore, the framework could be tailored and applied in different project contexts.
