12. 3.2PROCESS OF LAYING A SLAB:
In this all the sophisticated equipments are used to finish the work in easy and
simple method. The thickness of each slab is 20cm and between 2 wings a strip is not casted
immediately but casted after 25 days known as Expansion strip. The steel rods used in
construction are THERMAX STEEL from Germany.
Also shaft spaces are provided in slab for plumbing work
Figure 3.4, 3.5 views of shafts on and below the surface of the slab
Figure 3.6, 3.7 describes work of electrical conduting and cup locks support
After framing using shutter boards filmed with shuttering oil, electrical
conduting will be done, here cup locks are used to support the frame, and then concrete is
poured over the frame with the help of hydraulic jack and concrete pipes which are used to
pump the concrete from transit mixer to the place where slab has to be laid. To prevent
coagulation inside pipes, first a cream slurry cement paste has to be passed through pipes for
smooth flow of concrete
12

13. Tower cranes are used to move the required material from one place to other in
site both vertically and horizontally. The tower cranes can with held the wind force up to
height of 30m, beyond which they need to be clamped to nearby column of building for
support.Each tower crane costs about Rs.95 lakhs
Figure3.8 view of the tower crane from the site office
3.3BATCHING PLANT:
M40 concrete mix is used here for the construction of structure. A separate batching plant is
present near the site for the construction of lake verandahs and hill crest structures.
Figure 3.9 batching plant with a transit mixer

14. Figure 3.10, 3.11 describes the control panel and closer look to batching plant respectively.
A Transit mixer is used to transfer concrete from batching plant to the work site.It
carries around 7cubic mtr volume of concrete and takes about 15 min to load.
The main components of batching plant are
Control panel
Silos
Cement storage godown
Small tower crane for pushing ingredients into mix using trayThe batching plant
consists of silos which are used to store flyash and chemicals accelerators and
retarders.

fine aggregate (pit sand, dead river sand),cement, fly ash, water ,chemical admixtures .The
W/B Ratio of M40 Mix is 0.32
The chemical admixtures used are MYK Save mix SP
3.4Q/A & Q/C LAB (Quality assurance &quality control lab):
In this lab the quality and strength of various building materials like cement, sand,
concrete, water, coarse aggregate are tested using various testing machines and apparatus like
vicat apparatus,
Compression testing machine
flakiness and elongation index gauges,
volume measuring jars
digital weighing scale(20kg max. and 2gm accuracy)
sample collecting trays
pycnometer

3.5LAYING OF COLUMNS:
Figure 3.15 represents view of various columns from below ground surface
16

17. Figure 3.16, 3.17 describes frame work for column concreting and tor rings respectively.
Columns are laid under utmost care. steel rods are firmly placed and these
are connected using different types of TOR RINGS with the help of binding wire. About 8
Tor rings are provided at spacing in every column. Basically tor rings are of different types
like rectangular, square type, triangular, trapezoidal used for connecting various amount of
steel rods.tie rod, ropes are used to place the shutters firmly around the column where the
concrete is to be laid. Once the shutter is firmly placed then the concrete is filled manually till
0.5 mtr in order to avoid HONEY COMBING. M40 grade concrete is used for laying
columns. The date on which concreting is done to a column is written on column so that care
has to be taken to cure it for 14 days
17

18. Figure3.18 the checklist for column concreting
Prior to concreting of a column it should fulfil all the requirements of the
checklist for the column concreting ,it checks all the activities and should meet the
acceptance criteria after checking the report will be signed by Foreman, Site engineer and
Sector engineer before giving a nod to concreting

23. CHAPTER 4
CONCLUSIONS
From the field study report, it is evident that the construction is going on full swing, but
from according to the project monitoring chart, the project is lagging behind the schedule for
a period of about 6 months.
As dated on 1st june2012 the construction for slab for 3th floor is going on and still
about 24 floors are to be constructed. The schedule to hand over the project is dated for
January, 2014 at the earliest.
To accomplish this task the work should be done in 2 batches of workforce throughout
the day and the developers should lend more financial support than present.
Gracing the Hulimavu Lake, this most happening realty destination for the elite will be
a self-sufficient and all encompassing community where its residents will prosper forever.
