Architecture Phases in Costa Rica

Before any design work begins, a rigorous feasibility and concept phase defines what can actually be built on the property and what it will cost — aligning aspirations with physical and regulatory reality before significant design investment is made. This phase is not always formally named in small residential projects, but its functions are essential regardless of project scale. Skipping feasibility and jumping directly into design produces expensive revisions when site constraints, zoning limits, or budget reality collide with the design concept.

Site analysis in Guanacaste covers: topography survey (if no recent topo exists); orientation analysis (solar angles, prevailing winds); vegetation survey (protected trees, SINAC restrictions); soil conditions (visual assessment, preliminary borings if complex); utility service availability (ICE, AyA/ASADA, RACSA/fiber); access (road condition, municipal or private road, right-of-way width); and visual analysis (views to protect, views to screen). Zoning verification requires obtaining the official uso de suelo from the municipality: COS, CUS, setbacks, height limit, permitted uses, and any special overlay (ZMT coastal zone, tourism zone, conservation overlay).

The conceptual program defines the project’s functional requirements: number and type of spaces, approximate areas, indoor/outdoor relationships, privacy hierarchy between spaces, guest vs. private zones for rental properties, and operational requirements (kitchen type, laundry, storage, parking). A well-developed program at Phase 0 prevents the most common design error: starting with an image or style preference and then discovering the program does not fit the site or budget. Program drives design, not the reverse.

Schematic design translates the program into architectural form — floor plan options, massing studies, section sketches, and concept imagery that establishes the fundamental design direction. This phase produces enough definition to evaluate: whether the program fits the site within zoning constraints; how the building responds to sun, wind, and views; whether the design direction satisfies the owner’s aesthetic vision; and whether the preliminary budget is credible for the scale and quality defined. Schematic design is the right moment to explore fundamentally different design options — after this phase, changes become progressively more expensive.

In Costa Rica, CFIA fees to the professional team are calculated as a percentage of construction cost, set by the CFIA fee schedule (Arancel). The schedule assigns fee percentages by phase: typically 8–12% total professional fee for a residential project, split across phases approximately as: Schematic Design 15%, Design Development 20%, Construction Documents 30%, Bidding/Procurement 5%, Construction Administration 30%. Understanding this structure helps clients know what to expect at each phase and ensures the professional team is properly compensated for each stage of work.

3D visualization is standard practice for Guanacaste projects at schematic design — clients making investment decisions from abroad need compelling visualizations that communicate the spatial quality of the design, not just floor plans. Photorealistic 3D renders of key spaces (main living area, pool terrace, master bedroom) and exterior views are the most effective communication tools at this stage and should be included in the schematic design deliverable for any project above $500,000 in construction value.

Design development advances the approved schematic design into a fully coordinated design with defined structural system, MEP (mechanical, electrical, plumbing) system layouts, materials and finishes palette, and architectural details at all critical conditions. This is the phase where the structural engineer begins their calculations, the MEP engineers define their systems, and the architect develops all major interior and exterior details to the point where they can be fully drawn in construction documents without further design decisions.

Materials selection at Design Development is critical because material choices affect structural design (heavy tile vs. light wood decking affects roof structure loads), MEP coordination (which fixtures require which rough-in sizes), and budget precision. A design development set with undefined materials — “tile TBD”, “fixtures TBD” — produces a construction document set that cannot generate accurate bids, leading to either post-bid allowance surprises or low-ball bids that explode during construction. By the end of Design Development, every material in the project should be specified at least to quality level and approximate cost, enabling a reliable project budget update.

Design Development is also when the SETENA environmental assessment is initiated for projects that require it. SETENA review can take 3–9 months and runs in parallel with final design and CFIA document preparation — it should not be left until after design is complete. PDC initiates SETENA simultaneously with Design Development for all applicable projects to prevent this becoming a critical path delay.

Construction documents are the complete technical description of the building: architectural drawings, structural drawings and calculations, electrical drawings, plumbing drawings, mechanical drawings, site plan, and written specifications. All drawings must be stamped by CFIA-registered professionals in each discipline: architect (CACR), structural engineer (CFIA), electrical engineer (CFIA), and plumbing engineer (CFIA). The complete set is submitted to the local municipality through the CFIA’s APC (Administración de Proyectos de Construcción) online platform for plan review and permit issuance.

Common reasons for plan review rejection in Guanacaste municipalities: missing CFIA stamps or outdated professional registrations; incomplete structural calculations (missing load combinations, missing concrete mix design); unclear site plan (no survey reference, unclear setback dimensions); missing accessibility compliance drawings; plumbing drawings that do not show the connection to the AyA/ASADA system; and electrical one-line diagrams that do not match load calculations. Each rejection requires a formal response and resubmission, adding 3–8 weeks to the permitting timeline. A complete, well-prepared construction document set submitted once is worth far more than a fast submission that generates multiple RFIs.

CFIA professional fees paid at permit submission are calculated on the declared construction value using the CFIA fee schedule. These fees are paid directly to CFIA (not to your architect/engineer — those are separate professional fees). For a $1,000,000 construction value project, CFIA fees typically run $15,000–$25,000, split among the professional disciplines. Municipal permit fees are separately calculated by the municipality and typically run 1–2% of declared construction value. Budget these costs in your project financial model from the feasibility stage.

Once the permit is obtained, Phase 4 (Bidding) releases the construction documents to qualified contractors for competitive pricing. A structured bid process with a defined bid form, pre-bid site meeting, addendum management for questions and clarifications, and comparative bid analysis protects the owner from scope gaps and enables an apples-to-apples comparison between competing bids. Phase 4 typically runs 3–6 weeks for residential projects and 6–10 weeks for larger commercial or hospitality projects.

Phase 5 (Construction Administration) is where the architect and engineers provide oversight of the contractor’s work: reviewing shop drawings and submittals, responding to contractor RFIs, conducting site visits at critical construction milestones, certifying contractor payment applications, and documenting any field conditions that require design responses. CFIA requirements mandate that each registered professional visit the site at defined construction stages and file progress reports — these are not optional formalities but legal requirements of the registered professional’s license.

Phase 6 (Project Closeout) covers substantial completion inspection, punch list generation and resolution, as-built drawing preparation, systems commissioning, utility connection finalizations, habitability inspection by the municipality, and formal project delivery to the owner with all warranty documents, equipment manuals, and CFIA final reports. A complete closeout package — permits, as-builts, warranties, manuals, final CFIA reports — is required for insurance purposes, future sale, and financing. Projects without proper closeout documentation have difficulty obtaining full appraised value or clear title status for future transactions.
