Electrical

The power and lighting backbone. First-fix goes in before walls and ceilings close; second-fix finishes the job.

Electrical runs in two passes. The first fix — conduits, back boxes and cable pulling — happens early, while walls and ceilings are still open. The second fix — fitting switches, sockets, light fittings and the distribution board — comes near the end once finishes are in.

What it covers​

  • Distribution board, circuits and protective devices.
  • Conduiting, wiring and cable management.
  • Power points, switches, data and lighting points.
  • Final connection and testing of light and power.

Where it sits in the sequence​

First-fix is one of the earliest trades, running right after demolition and alongside aircon and plumbing first-fix. It must be complete before partitions and ceilings close up. Second-fix returns late, overlapping light & sanitary fittings.

What a PM watches for​

  • Coordination with the ceiling. Lighting layout has to be set before the ceiling closes. A change after that means opening it back up — log it as a variation.
  • Licensed work. Electrical work that ties into the supply must be done and certified by a licensed electrical worker. Don't let unlicensed hands near the DB.
  • Sequencing the second-fix. Don't fit delicate fittings before painting and cleaning — they'll get damaged or dirtied.
