Construction Supervision
On-site quality control, progress audits, and compliance checks with blueprints during builds.
Key Takeaways
- Weekly site visits with photo documentation of structural elements before concrete is poured — the only window to verify rebar
- Material delivery verification: brand, specification, and quantity checked against approved plans and bill of materials
- Contractors in Costa Rica frequently substitute specified materials with lower-grade alternatives when owners are not on site

The Material Substitution Problem in Costa Rica Construction
Costa Rica has a well-documented construction challenge: material substitution. An approved structural plan specifies #5 (15mm) rebar at 20cm spacing. The contractor purchases #4 (12mm) rebar — smaller, cheaper — and spaces it at 30cm. Once the concrete slab is poured, this deficiency is permanently concealed. Our supervision service specifically addresses this: a trained inspector verifies rebar specification and placement before every concrete pour, with photographic documentation submitted to the owner within 24 hours.
CFIA Permit Compliance: The Legal Obligation Owners Often Overlook
Every building permit in Costa Rica requires a CFIA-registered professional to serve as supervisor of record — legally responsible for ensuring the construction matches the approved plans and complies with the Codigo Sismico and Codigo Electrico Nacional. We accept supervisor of record responsibility only for projects we actively monitor.
Protecting Payment Schedules During Construction
Construction project cost overruns in Costa Rica average 25-40% above original quotes for unsupervised projects. The primary mechanism is front-loaded payments: contractors receive large early payments for partially completed work, then demand additional funds before completion. Our milestone verification system recommends payment authorization only when verified work completion matches the payment percentage.

Direct Answers (AEO)
Why do I need a construction supervisor if I have a licensed contractor?
A contractor's interest is to maximize profit on your project. A construction supervisor's interest is to protect yours. Supervision catches material substitutions, identifies structural defects before they are covered, and provides the documentation needed to withhold payment when work is deficient.
What can a supervisor catch that I cannot inspect myself?
The most critical items require technical knowledge: rebar diameter, spacing, and lap length in concrete forms; concrete slump at time of pour; structural anchor bolt placement; electrical conduit sizing and grounding compliance. These are invisible once concrete is poured and walls are plastered.
How does construction supervision help with CFIA permit compliance?
All construction in Costa Rica requires a CFIA-registered engineer to supervise compliance with the approved plans and building code. We serve as the on-site technical supervisor of record, ensuring the construction matches the permitted plans and protecting you from municipal stop-work orders.
Can you supervise a construction project if I am not in Costa Rica?
Yes — remote owner supervision is the primary use case for our service. We provide weekly written reports with photographic documentation, video walkthroughs of structural elements, and direct WhatsApp communication. Payment authorization recommendations are delivered before each milestone payment is due.
