Updating Financial Contingency in Execution of Typologically Diverse Construction Projects

The article presents research findings on updating financial contingency estimates for typologically diverse construction projects. The research was carried out from 2006 to 2024 on a sample of 41 investment tasks, represented by five different construction sectors, in which 547 measurements were made of the deviation of the earned cost of construction works from its planned values. The study found significant variability in the cost performance index (CPI) across different construction types. Box plots were determined, and their statistical interpretation made it possible to determine the actual financial contingency, the variation in which in the groups of residential, office and hotel buildings, as well as shopping and logistics centres, is in the range of 3% to 30%. The article concludes with recommendations for banks financing investment tasks in the direction of making financial contingency more realistic when making sustainable lending decisions.
