Typical Flat Plan

Cont.Project Type: Residential Towers No. of Towers : 27 Total Units(Flats): 4000 Total Area Covered : 30 Acre Tower Type: Tower A: G + 32 Tower A1: G + 35 Tower A2: G + 38 Tower B: G + 32 Tower B1: G + 38 Tower D: G + 38Structural Details It is R.C.C Framed structure.STRUCTURE DESIGN LIFE: 100 YEARSInterior Flat Specification 2/3/4 BHK spacious apartments Clear Room Height: 3100mm (3.1m)FoundationThe construction site is close to Yamuna river so the water table is high and also the soil is sandy (i.e. poor shear strength),so Pile foundation is designed for structure with 2600 mm thick pile cap (Raft) covering entire tower area. Water Level at construction is high so Initially dewatering is done prior to the start of foundation work. After dewatering soil is excavated to a certain required depth and compacted at OMC (optimum moisture content) required.Major activities of foundation workExcavationPile workPile load testPile chippingdewateringRaft layout, reinforcement work & casting workFoundation DetailPile Length= 15m Pile Diameter= 450mm Maximum no. of Piles used= 295 Type of Piles= cast-in-situSpacing centre to centre= 1200mm Reinforcements used in Raft= 32mm and 25mm Steel grade= Fe-500DReinforcement WorkSlab R/f & shuttering work Steel Grade: Fe 500D Concrete Grade : M25 Steel Bar Dia. used: 6mm,8mm,10mm, 12mm Nominal cover: 25mm Qty. of steel / floor: 21 tonne. Type of shuttering used Conventional & system shutteringMajor activities involve in slab castingBBS preparation as per structural drawingcutting of steel as per size & shape shown in BBScolumn layoutshifting of steel to work placebar banding workcolumn shuttering & plumb checkcastingcuringDe-shutteringBar bending schedule


Continue.Chair Used as spacer b/w top & bottom Reinforcement in slabDetails of chair bar (for 150 mm thick slab)Diameter of bar generally taken 10 mm.Generally the total length of chair bar used in the slab of 1.2 m.Generally it has two legged, length of one leg approx. 400 mm.Length of middle portion of chair bar approx. 400 mm, and height is about generally taken 80 mm.

Steel Grade : Fe 500D Qty. of steel /Floor including tie bar: 55 ton Steel bar Dia. used: 12mm to 32mm Mechanical joint for column longitudinal reinforcement is provide using coupler/reducer in case dia. of steel is > 16mm & lap of 36D is provide for bar dia. 16mm. Grade Of Concrete: M50

Typical Column TieShuttering/FormworkForm work is the term given either to temporary or permanent moulds into which concrete or similar materials are poured.

Types of form work/shutteringConventional shuttering. Traditional shuttering (Pranav system).
