Extraction of underlying factors causing construction projects delay in Nigeria

Purpose This paper aims to establish the most underlying factors causing construction projects delay from applicable. Design/methodology/approach The conducted survey of experts using systematic review vast body literature which revealed 23 common affecting delay. Consequently, this study carried out reliability analysis, ranking significance index measurement parameters (SIDP), correlation analysis and factor analysis. From result grouped a specific into three six applicable that correlated strongly with project Findings finds all test be consistent. It suggests quality control, schedule/program work, contractors’ financial difficulties, political influence, site conditions price fluctuation for delay, are in top 25% according SIDP score at same time associated Research limitations/implications is recommending prospective research should use qualitative inductive approach investigate whether any new, not previously identified, impact can discovered as it followed an approach. Practical implications includes policymakers industry Nigeria focus on measuring key suppliers’ delivery performance late materials by supplier rescheduling work activities extra or waiting workers well management team site. Also, stakeholders encouraged leverage amount data produced backlog schedules, as-built drawings models, computer-aided designs (CAD), costs, invoices employee details, among many others through aid state-of-the-art driven technologies such artificial intelligence machine learning make business decisions will help drive further profitability. Furthermore, these climatological obtained weather observations minimize bad during construction. Originality/value establishes (late supplier, poor decision-making Inclement weather)
