RAMP CALCULATION | QUANTITY SURVEY | VOLUME OF CONCRETE & AREA OF SHUTTERING

 

For a given drawing of Lift-Pit find

1. Volume of Concrete

2. Area of Shuttering

(A) Solution for Ramp:

1. Ramp at the entrance:

L = 10.547 m ; B = 4.0m ; T = 0.20m

c = Ѵ(a² + b²)

c = Ѵ(9.80² + 3.90²)

c = 10.547m

 

(a) Volume of Concrete for Ramp = area x thickness of Ramp

= L x B x D

= 10.547 x 4.0 x 0.20

= 8.437 m³

 

(b) Shuttering area for P.C.C bed = (L+B) x 2 x D

= (10.547 + 4.0) x 2 x 0.20

= 5.81 m²

 

2. Ramp at exit:

L = 10.547 m ; B = 4.20m ; T = 0.20m

c = Ѵ(a² + b²)

c = Ѵ(9.80² + 3.90²)

c = 10.547m

 

(a) Volume of Concrete for Ramp = area x thickness of Ramp

= L x B x D

= 10.547 x 4.20 x 0.20

= 8.859 m³

 

(b) Shuttering area for P.C.C bed  

= (L+B) x 2 x D

= (10.547 + 4.20) x 2 x 0.20

= 5.89 m²

 

(i) Total Concrete for both Ramps = 8.437+ 8.859 = 17.296 m³

 

(ii) Total Shuttering area for both Ramps = 5.81 + 5.89 = 11.70 m³
