Fachadas y parcela

Etapa de trabajos exteriores que abarca la instalación y acabado de sistemas de fachada y zócalo, la gestión del agua superficial y subterránea del terreno, la conformación de pendientes alejadas del edificio, la preparación para paisajismo y la instalación de iluminación exterior. El objetivo es evitar la entrada y acumulación de agua en la envolvente, asegurar la durabilidad de las superficies y facilitar posteriores trabajos de paisaje y servicios. La ejecución depende de las condiciones climáticas, la exposición y la coordinación con estructuras y acabados interiores.

Resumen de control del stage

Resumen de la etapa

Facade and site works are the stage where envelope performance is either protected or quietly undermined by final levels, splashing water, blocked drainage, and rushed external completion. The budget risk here is high because defects often look cosmetic at first, but the underlying cause is usually water path, clearance, or interface logic at the building edge.

Quality gates del stage

Inspect facade interfaces at openings, plinths, terminations, and movement joints before final cleaning and handover pressure push teams to close too early.
Verify finished ground, paving, and planter levels against plinth and damp-protection clearances, not against visual preference alone.
Flow-test inlets, channels, and stormwater release paths after site levels are complete, not before the last landscape changes.
Protect finished facade surfaces during paving, grading, and landscape works so final defects are not dismissed as minor damage.
Do not sign off external completion without maintenance access and a clear drainage-cleaning logic.

Checklist por work package

Facade systems and finish continuity #ST8-FAC-FACADE-001

The facade should be accepted as an operating envelope, not as a painted surface. The critical controls are continuity of layers, interface discipline, and protection from late site damage.

Qué verificar

Inspect openings, penetrations, movement joints, and finish terminations as one continuous weather line.
Verify flashings, drip edges, and sealant joints are installed to shed water away from the wall, not only to close visible gaps.
Check that late site operations have not chipped, stained, or bridged critical facade details.

Qué suele salir mal

Facade teams complete their scope correctly, but later paving or landscape work destroys the interface logic.
Sealant is used to hide poor geometry instead of completing a proper movement detail.
Facade staining starts early because water is allowed to rebound or track from nearby surfaces.

Site drainage and stormwater release #ST8-SITE-DRAIN-003

Site drainage is the external operating logic of the project. If outlets, inverts, and maintenance access are wrong, water will test the weakest edge of the building first.

Qué verificar

Confirm drains, channels, gullies, and outlet levels still work after final paving and landscape build-up.
Perform a practical flow review so water movement is verified in the real finished geometry, not assumed from design intent.
Check inspection covers, cleanouts, and access routes remain usable after decorative completion.

Qué suele salir mal

Drain routes were correct on drawings but are no longer correct after field level changes.
Inlets are placed where they are easy to build, not where water actually collects.
Maintenance access is buried or obstructed by landscape or hardscape decisions.

Final grading and building-edge falls #ST8-SITE-GRADE-004

Final grading is where the site either protects the building or starts feeding water back toward it. This package must be checked against the real edge conditions of doors, plinths, drains, and neighboring surfaces.

Qué verificar

Verify falls away from the building with spot levels at doors, corners, plinths, and drain approaches.
Check that topsoil, mulch, and decorative stone do not erase the designed clearance or create hidden dams.
Confirm transitions between paving, planting, and drainage features preserve the intended water path.

Qué suele salir mal

The drawing fall is correct, but the field finish becomes flat after multiple trade adjustments.
Landscape materials are topped up late and bury drainage or plinth clearances.
Local ponding appears at corners and entries because grading was treated as visual shaping only.

Evidencia antes de aprobar

Photo set of facade interfaces, plinth zones, movement joints, and final terminations after external works are complete.
Spot levels or as-built confirmation for finished ground, plinth clearance, drain inverts, and outlet levels.
Drainage flow-test record and maintenance-access map for inlets, channels, and inspection points.
