Unkontrollierte Zusatzkosten durch schlecht verhandelte Änderungsaufträge

3 verified sources

Definition

Manual change order negotiation processes lack real-time cost benchmarking or supplier rate validation. Contractors approve labor rates, material costs, and overhead multipliers without cross-checking market rates, leading to 5–15% cost premiums on change orders. VOB Part B §2 requires transparent pricing but manual workflows skip verification steps.

Key Findings

  • Financial Impact: €10,000–30,000 per project; 5–12% overrun on change order budgets
  • Frequency: Per change order; compounds across 5–15 changes per project
  • Root Cause: No standardized unit pricing reference; manual rate approval without benchmarking; time pressure during negotiations
