Causes of Cost Overrun in Public Construction Works from Risk Management Perspective

Maria Carolina Gomes de Oliveira Brandstetter's paper analyzes the main causes for contracting additional services in public construction works. The field study involved an analysis of contracts for new and completed works at a public higher education institution, using lexical analysis of justifications. The results indicate that the highest risk index corresponds to the project category, with 53% of addition frequency and 56% of financial impact.

Use Cases

• Categorizing causes of cost overrun based on the proposed risk taxonomy.
• Measuring financial impact per risk category via quantitative analysis.
• Reducing subjectivity in risk mitigation by associating lexical and documentary analyses.

Strengths

• Proposes a new categorisation of cost overrun causes based on a systematic literature review.
• Quantifies financial impact, with the project category showing 56% impact and 53% frequency.
• Uses lexical analysis software (Iramuteq) to analyze justifications for contract additions.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Geographic scope is limited to a single public higher education institution.
