1. PROJECT COST IS NEAR ABOUT 200 CRORE

2. NINE TOWER

(RESIDENTIALBUILDING,HOSPITAL)

3. EACH TOWER HAVE G+18 FLOOR

CPWD &NATIONAL BUILDING CODE ISI 456-2000

Area is bounded by GI sheet A temporary layout by the help of lime

within area

Help of JCB machine at the required depth(1300mm from ground surface)

Levelling of excavated soil surface

• 100mm thickness

• Grade M10(1:4:8)

• Use of machine mixing

• Placing as well as leveling

• Concrete (M40, grade)• Steel (Fe 500 grade)• Water( used for curing , mixing , soil

compaction, grouting)

Column layout on pcc by the help of total station According to drawing

This foundation are used in following cases-

1. When the bearing strength of soil is very low2. Characteristics of soil changeable3. Soil strata should be loose like as marchland4. Avoiding the differential settlement of building It is more economical and simple as compare to pile foundation.

• THE MAIN BAR & DISTRIBUTION BAR HAVE 30MM DIA AT BOTTOM NET.

• AS THE PROCESS FOR TOP NET & FOR SEPRATION THESE NET CHAIRS ARE USED

• CHAIR IS THE STEEL BAR THAT USED TO SEPRATED THE TOP AND BOTTOM NET.

• FIXED THE COLUMN REINFORCEMENT AT THE POSITION OF COLUMNS AND BOUNDED BY THE 24GAUGE WIRE.

• COLUMN HAVE 16 NOS. @ 30MM DIA.

• LAP LENGTH OF COLUMN 50D OF BAR.

• (IN CASE OF USED DIFFERENT DIA OF BAR LAP LENGTH IS PROVIDED ACCORDING TO GREATER DIA OF BAR.)

• VERTICAL TIESE PROVIDED 10MMØ @150MM C/C.

• AFTER MIXING THE CONCRETE FROM CONCRETE PLANT , IT SOULD PLACED ON SITE WITH HELP OF PIPE LINE.

• FOR COMPACTING USED NEEDLE VIBRATOR 1MIN. AT A PLACE .

• GENERALLY VIBRATOR HAVE 4000CYCLE/MIN.

• DIA OF VIBRATOR NEEDLE HAVE 60MM.

• Layout of column

• Reinforcement (according to drawing)

• Shuttering

• Checking of shuttering in inclination with help of plumb-bob

• Testing of material at site(cube test, slump test)

• Concreting

• Needle vibrator used max 1 min. in a place

Slump test used to check the workability of concrete .

Slump test have some appratus-

1. mould-

Bottom dia 20cm & upper dia 10cm

Height 30cm

2. tamping rod

16mm dia & length 60cm

In slump test material have filled in 4 layer.

Each layer tamping 25th times.

• CUBE USED TO CHECK THE COMPRESSIVE STRENGTH OF CONCRETE

• SIZE OF CUBE 15CM ×15CM ×15CM

• AFTER 28 DAYS CURING OF CUBE, FIXED IN THE COMPRESSION MACHINE AND CHECK THE COMPRESSIVE STRENGTH.

• SUTERING OF SLAB AND BEAM DONE AT SAME LEVAL.

• GENERALLY SUTTERING HAVE USED OF –PLYWOOD , STEEL PLATE, MATELIC PROP.

PROVIDED 8MMØ @150MM C/C IN SLAB. PROVIDED 3NOS.20MMØ IN TENSION ZONE &

2NOS. IN COMPRESSION ZONE IN BEAM. PROVIDED EXTRA REINFORCEMENT AT EACH END

OF SPAN TO RESIST THE SHEAR FORCE.(3NOS. 16MMØ @ LENGTH L/7)

PROVIDED VERTICAL STRRIPS AT 150MM C/C IN BEAM.

AFTER REINFORCEMENT USED THE CONCRETING PROCESS.

• Lap length 47 time of main bar dia.

• Column cover 40mm

• 1/3 bars to be overlapped at one location

• Tie bars dia.- 12mm

• Spacing at beam column connection joint- 100m c/c

• Column will not be cast much than 2m height.
