Abstract
Built environment organisations face global challenges between business units, especially since the coronavirus pandemic (COVID-19) has profoundly disrupted the construction industry worldwide, including the management of construction megaprojects (CMPs). This research aims to develop a competency framework, for global integrated delivery (GID) transformative initiatives and future of work (FOW) global initiatives, to manage integration between lean construction (LC) practices and integrated project delivery (IPD) on construction megaprojects (CMPs) in contemporary multinational engineering organisations.
‘Mixed research methods’ involves a two-stage quantitative and qualitative research approach. In the context of CMPs, stage one consisted of a qualitative research methodology comprising a literature review to examine competencies, COVID-19 impacts, responses and key drivers (KDs) to integrating LeanIPD&GID; stage one outcomes propose a conceptualisation of LeanIPD&GID, a competency framework and FOW global initiatives. Stage two involved an empirical questionnaire survey for a set of 30 KDs arranged into five factor clusters (FCs), 226 respondents from 23 countries with an extensive cosmopolitan experience; analysis adopted structural equation modelling (SEM), descriptive and inferential statistics, percentage scoring analysis, principal component analysis (PCA) and Eigenvalues.
In the context of CMPs, stage one outcomes delivered a conceptualisation of LeanIPD&GID, a proposed competency framework and FOW global initiatives. Stage two concluded that the most significant KDs are ‘collaboration in design, construction works and engineering management,’ ‘coordination and planning of construction work,’ ‘senior organisational management support,’ ‘boosting implementation of LC, and integrating project delivery’, and ‘earlier and precise 3D visualisation of designs’. BIM adoption in the MENA region is higher than LC; the second is still taking its first steps, while IPD has little implementation. LeanBIM is slightly integrated, while LeanIPD integration is almost not present.
The research findings, conceptualised LeanIPD&GID principles, a proposed competency framework and FOW global initiatives, provided future research streams and directions; the study has provided a competency framework and FOW global initiatives for effective practical strategies for enhancing integration of LeanIPD&GID transformative initiatives on CMPs and will allow project key stakeholders to place emphasis on boosting LeanIPD&GID KDs.
