For sanitary fittings in a building (e.g., WCs, flushing pipes, lavatory basins, and sinks), the specification and rate typically include the cost of the fittings and their fixing. Which selection best reflects this?

Introduction / Context:
Sanitary items are generally supplied and fixed (S&F) under BOQ items that include both the cost of the fitting and the labour/materials for fixing it as per specification. This ensures a functional installation without micro-splitting basic operations into separate items.

Given Data / Assumptions:

• Items include water closets, flushing pipes, lavatory basins, and sinks.
• Standard plumbing practice bundles cost and fixing unless stated otherwise.
• Ancillary materials (e.g., screws, putty, small sundries) are assumed included in the rate.

Concept / Approach:
Specification language typically reads “supply and fix in position” for such items, meaning the contractor provides the article, transports, sets it in place, connects as needed, and leaves it ready for use. This bundled approach streamlines tendering and execution.

Step-by-Step Solution:
Check each item: WC, flushing pipe, basin, sink—all are commonly S&F.Therefore, choose the inclusive option “All the above.”

Verification / Alternative check:
Reviewing typical SOR entries confirms that sanitary fixtures include fixing, jointing, and making good.

Why Other Options Are Wrong:

• Any single item choice under-represents the standard practice across all listed fittings.

Common Pitfalls:
Omitting fixing accessories or sealants; misunderstanding when special valves or traps are separately measured.

Final Answer:
All the above.
