- Cutting, forming or drilling through walls, floors or ceilings to allow services to pass.
- Ensuring structural integrity is not compromised.
- Chasing block and brickwork for conduits or pipes.
- Lifting and replacing floors.
- Asbestos removal.
- Plant moving services.
- Sealing holes.
- Reinstating fire, thermal or acoustic separation.
- Constructing plinths.
- Making good plaster and other finishes.
- Maintenance access requirements such as access panels, decking, platforms, cat ladders and handrails.
Builder's work in connection is generally carried out by the main contractor for a mechanical and electrical sub-contractor and other such specialist trades. However, sometimes, the mechanical and electrical works might be part of the main contract and the builders work in connection sub-contracted.
