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
