Engineering rough-in work sequence
Rough-in engineering fixes the routes that later disappear behind floors, walls and ceilings. The main risk is not only missing pipes or cables, but conflicts, poor access and untested hidden work.

Secuencia recomendada de trabajo
01 Coordinate routes and service zones
Prevent MEP clashes before cutting, chasing or closing structure.
- Overlay plumbing, drainage, electrical, low-voltage, ventilation and AC routes.
- Reserve shafts, ceiling voids, service access and equipment clearances.
- Confirm condensate drainage, fresh-air routes and exhaust discharge points.
Punto de control: Rough-in installation should not start until service routes and access zones are coordinated.
Herramientas, equipos y acceso: Coordination drawings, Laser level, Chalk line, Access zone markup
02 Install conduits, pipes, ducts and sleeves
Place hidden services in the right position with future maintenance in mind.
- Install pipework, conduit, cable trays, drains, sleeves and supports.
- Maintain slopes for drainage and condensate lines.
- Protect penetrations, fire/smoke barriers and waterproofing interfaces.
Punto de control: Wall or ceiling closure should wait until supports, slopes and penetration details are checked.
Herramientas, equipos y acceso: Pipe cutter, Conduit bender, Core drill, Duct tools, Support fixings
03 Test and record hidden work
Make hidden engineering auditable before finishes create expensive access problems.
- Pressure-test water systems and leak-check drainage where possible.
- Continuity-test cable runs and label both ends.
- Photograph routes with dimensions before closing walls, floors or ceilings.
Punto de control: Do not close assemblies until tests, labels and photo records are complete.
Herramientas, equipos y acceso: Pressure test pump, Multimeter, Cable toner, Label printer, Photo log

Consumos de material para planificaci贸n
Los consumos son referencias de planificaci贸n. Las cantidades finales deben comprobarse con planos, especificaciones, normativa local y fichas de proveedor.
| Material o recurso | Base | Rango de planificaci贸n | Unidad | Nota |
| Electrical conduit | Gross floor area | 1.5-3.5 | lm/m2 | Higher for smart-home, lighting scenes and dense outlets. |
| Water and drainage pipe | Wet room | 6-14 | lm/room | Fixture count gives better accuracy. |
| AC refrigerant and condensate routes | Indoor AC unit | 3-12 | lm/unit | Depends on outdoor unit distance and drainage route. |
| Ductwork surface area | Served floor area | 0.20-0.60 | m2/m2 | Use for ducted AC or fresh-air systems. |
Controles de calidad antes de avanzar
- MEP routes are coordinated with structure, ceiling levels and access hatches.
- Drainage and condensate slopes are visible and checked.
- Water systems are pressure-tested before closure.
- Hidden work photo archive includes routes, dimensions and labels.
