5. BUILDING TYPOLOGY The first five floors of the main
building is used for a high-end
shopping mall and the remaining
47 floors of the main building is
utilized for a commercial offices
and five star hotel on top 5 floors.
There are segregated office space
from 6th to 14th floor with toilets
also provided on all these floor.
The central core is surrounded by
the office spaces and refuge area
at 24 m of height.

building is used as a parking
garage for both the building and
the remaining 19 floors is
residences. Parking provided for
about 2000 cars with super
efficient driveways and
personalized access controls

TYPICAL PLAN

7. STRUCTURE SYSTEM
● The structure comprises a
concrete core and post tensioned
concrete slab and spandrel beams.
● The average centre to centre
distance between columns is 9.5m
● The column is of 1.8m x 1.8m
● The tube system concept is based
on the idea that a building can be
designed to resist lateral loads.
● This assembly of columns and
beams forms a rigid frame that
amounts to a dense and strong
structural wall along the exterior of
the building.

18. Features
: ● Units of one grid bay x one floor height
factory finished (1.5x 3.9)
● Pressure equalized drainage system.
● Three barrier weather gasket system.
● Microwave cured EPDM gaskets for
better performance.
● Exposed gaskets of Silicon gaskets for
better UV resistance and performance.
● Continuous drainage at every floor.
● Complete unitized panel is factory
finished under control condition
● Special process of structural glazing in
controlled factory condition
● Glass totally free from stresses as glass
held by structural sealant
● Economical design with advance
technology
● Complete split mullion and split
transom profile becomes structural
value hence optimized material content
Heat Resistant Architecture.
The special quality glass used in the
construction reduces the thermal gain
of the building by 15%. So even at the
peak of the heat you will feel cooler,
even without the air-conditioning.
Fastest Vertical Elevation.
The Commercial Tower in Kohinoor
Square has 47 elevators with separate
elevator banks for different floor levels,
ensuring minimal wait time. This system
is called the Compass Navigation
System, which divides traffic between
the various elevators, ensuring a wait
time of no more than 29 seconds.

19. Facade Details:
● The façade consists of faceted unitized
aluminum curtain walls with provisions for high
performance double glass façades on the
tower. The towers are linked by a podium with
a façade of custom point-supported glazing on
specialty steel trusses.
● Diamond edges of the building having
aluminum flashing with LED lighting are the
unique feature
● The Unitized Panel with 15 mm vertical
movement would accommodate floor
movement, slab edge deflection, building creep
and thermal expansion at every floor unit. No
scaffolding required for unitized panel
installation. This is done by floor crane / panel
hoisting. Hence the installation is very fast at
site.
● The type of glass used were Spandrel glass as
DGU of 30mm (6mm HS + 18mm Air gap +
6mm HS) and Vision glass VLT –-36 per cent,
SHGC between 0.23, U value of 1.5 W/m2.k
(BTU 0.26). As per architectural intent, Grey
appearance of glass was used. The glass was
selected on the basis of higher external
Reflection value & Lower internal reflection
value.

21. FOUNDATION
The combined pile raft foundation
system is used.
It is a geotechnical composite
construction that combines the bearing
effect of both foundation elements raft
and piles.
The pile raft foundation system has
recently been widely used for many
structures, specially in high rise
buildings.
