Alterações de Escopo Descontroladas em Obras

2 verified sources

Definition

Residential construction projects in Brasil face uncontrolled scope alterations due to informal change management. Source [1] documents that 'many projects fail due to excess or uncontrolled alterations.' Without integrated change control systems, cost overruns accumulate as materials are ordered redundantly, labor is reassigned, and rework becomes necessary.

Key Findings

  • Financial Impact: 5-15% of project budget (typical range: R$ 50,000-500,000 per project depending on size)
  • Frequency: Occurs on 60-80% of projects with inadequate change control
  • Root Cause: Lack of formalized, documented change order approval workflows; absence of baseline scope freezing; manual tracking of modifications

Why This Matters

The Pitch: Brazilian construction firms waste 5-15% of project budgets annually on uncontrolled scope alterations and rework. Digitizing change order workflows with mandatory cost/schedule validation eliminates unauthorized modifications.

R$ 5,000-50,000 per audit finding (estimated based on typical SEFAZ fiscal enforcement ranges)

Gargalo Operacional em Aprovação de Alterações de Obra

2-5% of labor budget per project; typically R$ 30,000-150,000 annually for 50+ person workforce (10-20 idle labor days)

Decisões de Compra sem Visibilidade de Mudanças Aprovadas

3-8% of material budget per project; typically R$ 15,000-100,000 in wasted procurement

Multas por Não Conformidade com NR 18 - Segurança do Trabalho

R$ 89,624.89 to R$ 249,419.70 per project per inspection (depending on company size and non-conformities identified)

Multas por NF-e Não-Conforme em Faturas de Fechamento de Obra

Up to 100% of each non-compliant invoice value (R$ penalty); typical closeout invoice range R$ 10,000–R$ 100,000+. Additional exposure: criminal prosecution for tax evasion if deliberate.

Atraso em Recebimento por Rejeição de NF-e no Fechamento de Obra

Interest cost on delayed payment: assuming R$ 50,000 average closeout invoice, 5–14 day delay @ 0.5% daily financing cost = R$ 1,250–R$ 3,500 opportunity cost per invoice. Annual impact on 20+ projects: R$ 25,000–R$ 70,000.
