Impact

The concept of construction project development may be impaired without a good knowledge and successful management of the impact of environmental factors influencing the performance of such projects. This study aims to assess the impact of environmental factors on building project performance in the Delta State, Nigeria. The instrument used for the data collection was structured questionnaire and the target population consisted of clients (government and private developers) and four groups of professionals who were architects, builders, quantity surveyors and engineers. The tools employed were Mean Score, Spearman correlation, Kendall’s coefficient and Chi-Square. Twenty-nine variables were identified as factors having an impact on building project performance and they were categorized under clusters; political, legal, construction technological and resources, economic and financial, socio-cultural and physical. The result of the Spearman correlation analysis of time and cost overruns with the identified factors affecting project performance revealed that the clusters of Economic and financial and Political had significant relationship with time overrun on p-values of 0.004 and 0.011, respectively, while the cluster of Social and cultural had significant relationship with cost overrun with a p-value of 0.007. The research recommended that stakeholders should take cognizance of the variables under these three clusters for proper management and prevention of cost and time overruns.
