Payment Units – Common materials and their standard units in BOQ Which of the following statements correctly pairs the material with the usual unit of payment?

Introduction / Context:
BOQ unit conventions reduce ambiguity in supply and measurement. Bricks, cement, lime, and aggregates have standard units of account widely used in schedules of rates and tender documents.

Given Data / Assumptions:

• Standard materials for masonry and concrete.
• Prevailing practice in government/CPWD/PWD schedules.

Concept / Approach:
Identify the most common unit used in pricing and supply for each material and confirm consistency with mainstream schedules of rates.

Step-by-Step Solution:
Bricks ⇒ per thousand (1000 nos.).Cement ⇒ per 50 kg bag.Lime ⇒ per quintal (100 kg).Brick aggregate ⇒ per cubic metre (m^3).

Verification / Alternative check:
Cross-checks with typical SOR/BOQ templates confirm these units are standard entries for procurement and billing.

Why Other Options Are Wrong:

• a–d are each correct; hence the combined choice is “All of the above”.

Common Pitfalls:
Confusing “per tonne” versus “per quintal” for lime, or quoting aggregate by tonne instead of the volumetric unit specified in the BOQ.

Final Answer:
All of the above
