Purpose The purpose of this paper is to investigate critical success factors (CSFs) that enhance integration between building information modelling (BIM) and lean construction (LC) practices on construction mega-projects. BIM and LC have gained momentum in the past decade. Design/methodology/approach The Delphi survey technique was used to gauge opinions of a panel of 16 experts through a two-round Delphi questionnaire survey. Panel responses were scrutinised using inferential and descriptive statistical techniques. Findings In total, 30 CSFs were identified in the literature. The top ranked factor out of 30 that supports LeanBIM synergy was “collaboration in design, construction works and engineering management”. Other top rated CSFs were centric on people, data and technology elements. The research findings are important for project stakeholders, organisations, contractors, engineers and local authorities who implement LC and BIM synergies in construction mega-projects. Originality/value The research findings are important for project stakeholders, organisations, contractors, engineers and local authorities who implement LC and BIM synergies in construction mega-projects. The research recommends further hands-on training to increase the integration of BIM and LC practices in the architecture, engineering and construction industry and to enrich the extant body of knowledge in construction of mega-projects.

Purpose The construction industry encounters substantial challenges in its evolution towards sustainable development and to the adoption of building information modelling (BIM) technology and lean construction (LC) practices on construction mega-projects. This study aims to present critical challenges and to investigate the interactions of BIM and LC on construction mega-projects encountered by key stakeholders in their efforts to integrate BIM and LC. Design/methodology/approach A qualitative research approach is adopted to introduce and validate LC principles and BIM functionalities resulting from a detailed analysis of extant literature, followed by a conceptual analysis of the interactions between BIM and LC on construction mega-projects. A quantitative questionnaire survey is then used. Descriptive and inferential statistical tests are used for data analysis, and analysis of variance tests elaborate and validate results. Findings The research yielded ten BIM functionalities and ten LC principles, which are categorised in four principle areas and four BIM functionality groups. A research framework for analysis of the interaction between BIM and LC is then compiled. Originality/value Research findings and the proposed framework will enhance the adoption of BIM and LC practices on construction mega-projects and allow project key stakeholders to place emphasis on tackling crucial challenges and barriers identified in this research. The framework will guide and stimulate research; and as such, the approach adopted up to this point is constructive. The identified interactions between BIM and LC on construction mega-projects show positive synergies between the two.

This paper attempts to contribute towards investigating the existing literature base of stakeholder management (SM), provide a compilation, and define any gaps in this area. Besides, explore different groups of critical success factors (CSFs) and grouping these actors. This study is based on reviewing the literature. Therefore, more than a hundred research papers were searched by the key terms specified in a preceding literature review. Succeeding tours of abstract research surveys resulted in forty-two research papers being picked for the compilation. SM constructs were identified, and the following crucial analysis defined the literature base gaps. The most notable outcomes are the absence of research that has studied BIM-based stakeholder management, especially in mega projects. Additionally, further investigations are still required to study the SM influence throughout the different stages of the project life cycle and study the impact of project type and contract type in SM. However, there is still considerable debate about the SM nature and merits approach. This study presents a comprehensive gathering of all earlier identified SM processes through a structured approach. Additionally, a more realistic and practical methodology for the development and implementation of SM will emerge, and twenty-seven CSFs associated with SM in construction projects are identified. The study is expected to have a theoretical contribution to this subject, especially in the context of the Qatari construction industry.

Purpose The construction industry is facing massive challenges due to the huge construction development, and stakeholder management (SM) practices, especially on megaprojects. The purpose of this paper is to investigate critical success factors (CSFs) encountered by key construction stakeholders to enhance SM practices on mega construction projects (MCPs). Design/methodology/approach A questionnaire survey is carried out among the most important construction companies in Qatar. Three steps are used to finalize and evaluate the questionnaire before proceeding with the full survey, validity, pretesting and pilot study. Quantitative data analysis was conducted using the Statistical Package for Social Science software. Findings This paper identifies the key factors contributing to improving SM performance in MCPs; none of these is uncommon, but here they come together in a more integrative way. Research limitations/implications The limitations related to this research are briefly outlined as follows: the research was carried out in the State of Qatar. So, the findings are limited to the Qatari construction industry. The construction industry in Qatar is different from other countries where public projects have the priority to develop the infrastructure of the country prior to the world cup competition. The scope of this research is limited to MCPs. The impact of low awareness and knowledge of SM is not considered. However, the study is still reasonable and fortunately suitable to evaluate SM in MCPs. Practical implications Identifying these factors is expected to assist project participants in MCPs in improving projects’ performance and completing construction within the predefined time and cost. Originality/value This study makes a significant contribution through identifying the CSFs that lead to develop efficient SM in MCPs. Moreover, the research findings are important for project stakeholders, organizations, contractors, engineers and local authorities who implement SM in MCPs. Moreover, it will enhance the application of SM practices in construction megaprojects and allow project key stakeholders to place emphasis on tackling the crucial challenges identified in this research.
