👉WHAT IS QUANTITY SURVEYING

➡️Quantity surveying means generally materials take off preparation and measuring of quantities Such as length,Area,Volumes and Pcs for Construction projects

🏷Quantity Surveying can be cover different tasks like

*⃣preparation of specification.

*⃣Taking measurements of Construction works.

*⃣preparation of approximate cost estimate at the very early stage of the project.

*⃣preparation of detail cost estimate at different stages.

*⃣Valuation of property.

🏷PURPOSE OF QUANTITY SURVEYING

👉How to Calculate Staircase Concrete Volume

💫This infographic explains the step-by-step method for calculating the concrete quantity required for an RCC staircase.

🏷Calculate the number of steps using total height ÷ riser height.

❇️Find the horizontal length using steps × tread.

⏺Determine the waist slab length with the Pythagorean theorem.

⏺Compute the waist slab volume and single step volume separately.

⏺Add all step volumes to the waist slab volume to get the total concrete volume.

✅ Total concrete required for this staircase = 1.5 m³

👉Cement, Sand & Brick Quantity Estimation 1 Cubic Meter Brick Masonry Work

💫Brick masonry calculation is used to estimate the required number of bricks, cement, and sand for constructing 1 cubic meter of brick wall.

❇️Standard brick size with mortar is considered as 20 cm × 10 cm × 10 cm.

🚧Number of Bricks: ≈ 500 bricks
🚧Cement Required: ≈ 63 kg (about 1.25 bags)
🚧Sand Required: ≈ 9.28 ft³
🚧Mortar Ratio: 1 : 6 (Cement : Sand)

🏷This estimation helps civil engineers, contractors, and site supervisors calculate material quantities accurately, reduce wastage, and manage construction costs efficiently.

Concrete Block Calculation Guide

This guide shows how to estimate the number of concrete blocks, mortar, sand, and cement required for a 1 m² block wall.

A standard concrete block size of 400 mm × 200 mm covers 0.08 m², so approximately 12.5 blocks are needed per square meter. It also provides a simple method for calculating mortar and material quantities for masonry work.

Key Points

✅ 1 m² wall = 12.5 concrete blocks
✅ Standard block size = 400 × 200 mm
✅ Mortar is used to bond blocks together
✅ Sand and cement quantities can be estimated from mortar volume
✅ Useful for site estimation and material planning
