To help develop this article, click ‘Edit this article’ above.
The term ‘builder’s work in connection’ (BWIC) refers to builders work that is necessary as a result of other works, typically mechanical and electrical services but also specialist installations such as; lifts, escalators, roller shutters, hoists and cleaning cradles, and so on.
For example, the installation of mechanical and electrical services might require:
- 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.
This may involve works that require building regulations approvals and possibly testing certificates (for example, cleaning cradle restraining bolts).
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.
Builder’s work in connection should not be confused general site preliminaries such as; welfare provisions, site offices, plant, site waste clearance, and so on, which are priced separately.
Estimators typically price builder's work in connection as 7% of the specialist work value.
