📜 Relevant IS Codes for RCC Concrete Measurement

IS 456:2000 - Code of practice for plain and reinforced concrete (M20/M25 grade specifications)
IS 1200 (Part 2):1974 - Method of measurement of building and civil engineering works – Concrete works
IS 10262:2019 - Concrete mix proportioning guidelines for RCC

📐 A. Isolated Trapezoidal Footing Concrete Quantity (C1 to C13)

Trapezoidal footing calculation using formula method as per IS 456:2000

📐 Trapezoidal Footing Formula

Total Volume = Volume of Bottom Rectangular Portion + Volume of Trapezoidal Portion

Volume of Trapezoidal Portion = h/3 × (A₁ + A₂ + √(A₁ × A₂))
Where: A₁ = Bottom Area (L×B), A₂ = Top Area (L×B), h = Height of trapezoidal portion

Footing ID	No.	Bottom L×B (ft)	Top L×B (ft)	Trapezoidal Height (ft)	Quantity (cu.ft)	Quantity (cum)
Trapezoidal Footing Calculation for C1 to C13 as per drawing dimensions
C1, C10	2	4.75×4.5	1.25×1.75	1.0	52.11	1.48
C2, C4, C5, C7, C8, C9	6	5.0×4.75	1.25×1.75	1.0	168.72	4.78

Total Footing Concrete Quantity (C1 to C13)					346.26 cu.ft	9.81 cum

📌 Sample Calculation for C1 Footing (Trapezoidal)

Bottom Portion: Length 4.75 ft × Width 4.5 ft × Depth 0.75 ft = 16.03 cu.ft

Trapezoidal Portion: h/3 × (A₁ + A₂ + √(A₁×A₂)) = 1/3 × (21.375 + 2.1875 + 6.84) = 10.02 cu.ft

Total for 1 footing (C1): 16.03 + 10.02 = 26.05 cu.ft (0.74 cum)

For C1 & C10 (2 footings): 26.05 × 2 = 52.11 cu.ft (1.48 cum)

📊 B. Column Concrete Quantity (Up to Plinth Level - C1 to C13)

RCC column from footing top to plinth level as per IS 456

📐 Formula: Column Concrete Quantity = Number × Length × Width × Height

📊 Column Concrete Measurement Sheet (Up to Plinth)

Column ID	No.	Length (ft)	Quantity (cu.ft)	Quantity (cum)
Columns C1 to C13 up to plinth level - dimensions as per structural drawing
C1 to C13	13	As per column schedule drawing	67.88	1.92
Total Column Concrete (C1 to C13 up to Plinth)			67.88 cu.ft	1.92 cum

📊 C. Ground Beam Concrete Quantity (GB1 to GB25)

RCC ground beams as per structural drawing and IS 456

📐 Formula: Ground Beam Quantity = Number × Length × Breadth × Depth

📌 Note: Ground beam dimensions as per drawing. 9"×15" beams have breadth 1.25 ft, depth 1.25 ft. 6"×15" beams have breadth 1.0 ft, depth 1.25 ft.

📊 Ground Beam Concrete Measurement Sheet (GB1 to GB25)

Beam ID	No.	Length (ft)	Quantity (cu.ft)	Quantity (cum)
Ground Beams GB1 to GB25 (9"×15" and 6"×15") - as per structural drawing

Total Ground Beam Concrete Quantity (GB1 to GB25)			197.53 cu.ft	5.60 cum

📦 D. Total RCC Concrete Quantity (Footing + Column + Ground Beam)

Total RCC Concrete = Footing Concrete (C1-C13) + Column Concrete (Up to Plinth) + Ground Beam Concrete (GB1-GB25)
= 346.26 + 67.88 + 197.53 = 611.67 cu.ft
= 17.32 cum (1 cu.m = 35.315 cu.ft)
