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.

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).
