Electrical pre-installation
Electrical pre-installation. Useful electrical information and guidance in Barcelona.
Main information
What it includes
Electrical pre-installation for a building under construction or before finishes: conduit, boxes and circuit routing before walls are closed.
Typical process
Assess the plans or planned layout → plan the circuit routing → install conduit and boxes → check before walls are closed.
Scope and availability
Built for the construction phase where partition walls can still be worked on before final finishes are applied.
Frequently asked questions
At what point in the build is the pre-installation done?
Before walls are closed and finishes applied, while the routing can still easily be adjusted if needed.
Can future circuit upgrades be planned in already?
Yes, it's worth planning for this at this stage so walls don't need opening later.
Who installs the final fittings (sockets, switches) afterwards?
Can be done in the same final build phase or in a later visit, as agreed.
