For contracting entities, following SCI tables reduces liability, improves project outcomes, and aligns with international best practices (e.g., FIDIC White Book for Independent Supervision). For engineers, adhering to SCI minimums is a professional obligation, not a market suggestion. Any bid below those tables should be presumed technically non-viable.
1. Introduction: The Role of the SCI in Technical Auditing The Sociedad Colombiana de Ingenieros (SCI), founded in 1887, is the oldest and most prestigious professional engineering guild in Colombia. While not a government regulatory agency, the SCI serves as a technical consultative body, an ethics tribunal, and a reference point for professional fees. One of its most influential contributions is the publication of suggested minimum fee schedules for engineering services, particularly for Interventoría (project auditing/construction supervision).
Ultimately, the SCI’s fee guidelines are a tangible expression of the principle that you cannot supervise a complex work with cheap, underpaid eyes . The fees and percentages above are illustrative based on SCI historical publications. Engineers and entities should consult the latest Boletín de Tarifas from the SCI’s Centro de Arbitraje y Consultoría or the Comisión de Tarifas for current values in COP.
| Direct Project Cost (COP) | Complexity Level | Suggested Monthly Fee (COP) | % of Monthly Work Value | |---------------------------|------------------|-----------------------------|---------------------------| | < 500 million | Low | 15 – 25 million | 3.0% – 5.0% | | 500M – 5 billion | Medium | 30 – 80 million | 2.5% – 3.5% | | 5B – 50 billion | High | 90 – 250 million | 1.8% – 2.5% | | > 50 billion | Very High / Mega | 280M – 800M+ | 1.2% – 1.8% (sliding) |
