# Calculate the Complete Quantity of Pipe Support Foundation

**Calculate the Complete Quantity of Pipe Support Foundation**

**calculate the volume of concrete and rebar excavation backfilling etc**

footing and pedestal. quantity of backfilling materials. a number of the base plate.

I have some given data

I have one pipe support drawing they have mentioned in all detail.

length of pipe support foundation =2.5m

width of pipe support foundation=1.5m

height of footing =0.500m

Total height of pedestal =1.5m

above ground =0.300m

length of pedestal =0.450m

width of pedestal =0.350m

**Now we calculate the excavation of pipe support**

total excavation of pipe support foundation = L×W×H

total excavation of pipe support foundation =2×1.5×1.7=5.1m³

this is the exact excavation of the foundation but for working space, we will do 600mm all side extra excavation. and 100mm for lean concrete. so its means the excavation is

**total excavation=3.2×2.7×1.8=15.552m³**

Now lean concrete

lean concrete is all side 100mm extra and the thickness of lean concrete is 100mm

so

**lean concrete =2.2×1.7×0.100=0.374m³**

Now concrete for the footing

concrete for footing =L×B×H

**concrete for footing =2×1.5×0.500=1.5m³**

now concrete for pedestal or column

concrere for pedestal or column= L×B×H

**concrere for pedestal or column=0.450×0.350×1.5=0.236m³**

this concrete is for one pedestal but we have 2 pedestals or columns for pipe support

**so total concrete for two pedestals =0.236×2=0.472m³**

**now we calculate the quantity of rebar for footing**

footing rebar

dia of the long bar =12mm

spacing of footing =200mm

dia of short bar=12mm

**Now calculate the footing long bar **

cutting length of long bar= total length -2(C.C)+2 bends

cutting length of long bar=2000-2(75)+2(19d)=2000-150+2(228)=1394mm=1.394m

Nos of long bar = width of footing/spacing+1

Nos of long bar =1500/200+1=8.5=9bar

total cutting length of long bar =nos of bar×length of one bar

**total cutting length of long bar =9×1.394=12.546m**

Now

cutting length of short bar=widht of footing-2C.C+2bends

cutting length of short bar=1500-2(75)+2(19d)

cutting length of short bar=1500-150+2(19×12)

cutting length of short bar=1500-150+456=1806mm=1.806m

Nos of short bar =total length/spacing+1

Nos of short bar =2000/200+1=11bar

total cutting length of short bar=nos of bar×length of one bar

**total cutting length of short bar=11×1.806=19.866m**

Now we calculate the weight of the short and long bars at one time because the dia between the short and long bars is the same so that why.

the total length of long and short bar =length of short of bar+length of the long bar

the total length of long and short bar =12.546+19.866=32.412m

weight of long and short bar =d²/162.25×total length

**weight of long and short bar =12²/162.25×32.412=28.766kg=29kg**

Now calculate the vertical bar

dia of vertical bar=16mm

height of pedestal or column=1.5m

length of pedestal=450mm

width of pedestal=350mm

cutting length of vertical bar=total height of pipe support foundation-bottom c.c -2dia of the bottom bar -top c.c +bottom bends+top bends

cutting length of vertical bar=2000-75-2(12)-50+(18d)+10d

cutting length of vertical bar=2000-75-24-50+(18×16)+10×16

cutting length of vertical bar=2000-75-24-50+288+160=2.299m

we have 8 nos of the vertical bar

we have 2 pedestals =8×2=16 nos

total cutting length of vertical bar =nos of bar×length of one bar

**total cutting length of vertical bar =16×2.299=36.784m**

weight of vertical bar=d²/162.25×total length

**weight of vertical bar=16²/162.25×36.784=58.038=59kg**

now

we calculate the stirrups length and nos of stirrups

we have two types of stirrups one is a rectangle shape and one is a diamond shape

Now 1st rectangle stirrups

Nos of rectangle stirrups =total height of pedestal/spacing+1

**Nos of rectangle stirrups =1500/150+1=11nos**

**we have 2 column=11×2=22nos**

cutting length of stirrups=2 sides 350+2 sides 250+2bends

cutting length of stirrups=2(350)+2(250)+2(9d)

cutting length of stirrups=700+500+2(9×10)

**cutting length of stirrups=1200+180=1380mm=1.380m**

the total length of stirrups =nos of stirrups×length of one stirrup

**the total length of stirrups =22×1.380=30.360m**

Now calculate the diamond stirrups

no of diamond stirrups=nos of rectangle stirrups

22=22

cutting length of stirrups=4 sides of diamond stirrups +2bends

cutting length of stirrups=4(215)+2(9d)=860+2(9×10)=1.040m

total cutting length of stirrups=nos of stirrups×length of one stirrup

**total cutting length of stirrups=22×1.040=22.88m**

Now calculate the weight of both stirrups

dia of stirrups =10mm

the total length of stirrups=length of rectangle +length of diamond

** total length of both stirrups=30.360+22.08=52.44m**

weight of diamond stirrup =d²/162.25×total length

**weight of diamond stirrups =10²/162.25×52.44=32.32=33kg**

**now we calculate the backfilling **

backfilling of pipe support foundation up to ground level.

Quantity of backfilling=quantity of total excavation – Quantity of total concrete footing, pedestals, and lean concrete

total concrete=footing and pedestal concrete+lean concrete

total concrete=2.346+0.374=2.720m³

**Quantity of backfilling=15.552-2.720=12.832m³**

**Nos of base plate =2**
