Building services: The 80/20 walk for the critical spots

Whether several trades are working at once or you find it hard to place the exact stage: do not get lost in technical details now. On your walk, focus on the building-services spots that become most expensive once plaster or floor build-up follows.

The red list: what you need to check immediately

Chased walls and structure

Horizontal or particularly deep chases in load-bearing walls are tricky. Photograph and inform site management before plastering.

Services on the bare floor

Kinked, damaged or overlapping pipes and cables can only be repaired with great effort after the floor build-up.

Open pipe ends without caps

Missing caps allow construction debris into pipes, causing hard-to-reach blockages later.

Debris and damage between trades

Cable offcuts under pipes or holes in vapour barriers are happily poured over — later causing poor sound insulation, cracks and disputes.

Interfaces you should document now

  1. Limit walk to open walls and floors

    Photograph open chases, floor services and pre-walls before they are covered. Ignore already finished areas.

  2. Photograph every issue twice

    Photograph the room first, then the spot with a folding rule for scale. Note the location and working area.

  3. Secure open ends and interfaces

    Check the tight fit of pipe caps and photograph any missing protective covers.

  4. Report issues before covering

    Inform site management in writing and request clarification before work continues.
