Expected out-turn of brickwork in cement mortar (foundation and plinth) Per mason per day, what is the typical out-turn (productivity) for brickwork in cement mortar in the foundation and plinth courses, under normal site conditions?

Introduction / Context:Out-turn (or productivity) norms are widely used in estimation and rate analysis to plan manpower and time. For brickwork in foundation and plinth, a standard benchmark per mason helps in preparing realistic schedules and costs.

Given Data / Assumptions:

• Brickwork is in cement mortar.
• Location of work: foundation and plinth.
• Normal working day, average site conditions (no unusual constraints).

Concept / Approach:Standard practice handbooks and departmental schedules provide indicative out-turns. Foundation and plinth masonry is generally faster than superstructure due to easier access and fewer interruptions, leading to a moderate productivity figure adopted for planning.

Step-by-Step Solution:

Verification / Alternative check:On constrained sites or with complex bonding, actual out-turn may reduce, but for normal conditions, 1.25 m^3 is consistently used in estimation references and BOQ planning.

Why Other Options Are Wrong:

• 1.00 m^3: Conservative; often used for superstructure or constrained work.
• 1.50 m^3, 1.75 m^3: Optimistic for routine planning; may occur only with exceptional productivity.
• None of these: Incorrect because 1.25 m^3 is the accepted planning norm.

Common Pitfalls:Blindly using high productivities without considering site constraints; not differentiating between foundation/plinth and superstructure masonry rates.

Final Answer:1.25 m3
