A switch position is not a service record
Do not treat a switched-off appliance, a closed valve or an unused meter as confirmation that demolition can proceed. Ask the relevant utility, qualified trade or project professional to establish the required work and the evidence that it has been completed. Do not attempt a disconnection yourself.
Distinguish the building from the work area
A full structure removal differs from a bathroom renovation or commercial strip-out. Some services may need to remain for occupied areas or base-building systems. Mark the removal boundary and the service interfaces so one trade does not assume another has already dealt with them.
Make handover visible
Keep the responsible contacts and any written confirmations with the project scope. Discuss access for service work and what must happen before demolition can start. If a previously unknown service is found, stop the affected work and have it assessed rather than improvising around it.
Bring these details to the conversation
Keep these items together so the people assessing the work are looking at the same scope.
- Affected utilities and retained systems
- Utility or trade contacts
- Required confirmations
- Dependencies before the removal begins
