Download CAD & PDF | Cast In Situ Pile Details, Estimate & Construction Process
Piles are column elements in a foundation that have the function of transferring the full load from the superstructure. Piles move the whole mass compact and less compressible to the surface or to the top of the rock.
According to cast in place, the pile is of two types: (I) Pre Cast Pile and (II) Cast In Situ Pile.
Cast In Situ Pile Details, Estimate & Construction
In this article, we discuss the cast in situ pile estimate, details drawing and the process of construction. And also free download the pile estimating spreadsheet and pile details pdf.
Cast In Situ Pile Details
A designer should provide complete guidelines for piles.
Pile layout and pile specification should always be precise for a good foundation.
If you make a better Pile of details read the full article of ” Make Pile Details In AutoCAD With DWG and PDF”
Pile Layout Plan
Clean pile point measurement from the gridline.
Must be mentioned to pile to pile distances in their group of the piles or pile cape.
Should consider ACI or regional building code system.
Pile Layout Plan
Design Specification
Clayerly draw pile size and length.
Draw the number of Rebar and spacing of the spiral bar.
Must be mentioned on the clear cover with a separate figure.

Cast In Situ Pile Estimate
From our above drawing:
Estimate for 24″ Dia Pile and Boring Length from E.G.L.= 75’6″, Casting Length is = 70′ (Don’t cast 5′-6″ EGL to Upper Pile Casting Level), but Rebar Length is = 69′ (Minus: EGL to Upper Pile Casting Level and Bellow 1 feet CC Casting)
Estimate of Casting
The casting Length is 70′ the concrete mix proportion ratio is 1:1.5:3 or f’c=3000psi [Mentioned in the drawing]
Casting volume:
= (πr^2 x Length of pile casting)
= (3.1416 x 1’^2 x 70′)
= 220 cft
Cement: (220 x 1.5)/(1+1.5+3)= 330/5.5 = (60 x 1) = 60 cft [1bag cement equal to 1.25 cft] so, 60/1.25 = 48 bag cement.
Sand: (220 x 1.5)/(1+1.5+3)= 330/5.5 = (60 x 1.5) = 90 cft sand.
Stone or Coarse Aggregate: (220 x 1.5)/(1+1.5+3)= 330/5.5 = (60 x 3) = 180 cft stone.
Note: But in reality, 5% to 20% fewer materials are taken
Estimate of Reinforcement or Rod
Reinforcement or Rebar Length is = 69′
Spiral Length = 66′
Stirup Center to Center = 6″ or .5′
Clear cover is =3″
16 mm Main Rod: (Number of Rebar X ( Length of Reber + Lapping ) x Weight of steel bars per feet) = (8 x ( 69′ + 2′) x 0.48) = (568′ x 0.48) = 273 kg
10 mm Spiral Rod: [((66 / 0.5) + 1) X ( 2π(12″ – 3″ )/ 12)] x 0.188 = (133 X 4.712) x 0.188 = 627 x 0.188 = 118 kg.
Total need 273+118 = 391 kg
