Twenty five (25) environmental factors were identified. Mean item scores of these factors were used to rank them in order of importance. The results of the study revealed that cost of borrowing was the most important factor that contributed to cost overrun with a mean score of 4.19. Weather, flood and erosion were also identified as important factors contributing to time overrun of construction projects with a mean score of 4.01 each.
