Fundamental Observation :
i In the EC issued, Basement 3 not included but
constructed at site.
We have obtained approval for parking of
6,247 cars and 12,131 two wheeler parking as
well as 25 bus parking within campus, for
which we have obtained EC for basement 1 and
2, Stilt level and the remaining as surface
parking.
During construction, we have provided one
more additional basement and stilt level for
parking, to avoid heat island effect due to open
parking planned earlier.
ii EC was issued for only 1 – IT block, but 4 IT
blocks constructed.
We wish to clarify that it is an IT Park
comprising of the blocks A,B,C,&D as per our
initial application and presentation to the
committee
iii EC was issued only to have Retail shop with
Basement -1, G.F and 3 floors, where as 13
floors are constructed.
Non-Processing Zone consisting of Hotel, Retail
and Residential has not yet been constructed.
Besides our revised amendment application dt
27.11.13 was made for amendment of product
mix from Retail /Residential to office towers.

24. Organic Waste Converter (OWC)
“ The Organic Waste is converted into homogenized
odour free output within 20 minutes through Bio
Mechanical Process and is converted into COMPOST
within two weeks which can be used in gardens and
landscape applications. With this system we are
effectively disposing food waste scientifically there
by reducing landfill burden to that extent. We are
collecting the food waste from our Food court and all
our tenants cafeteria. The waste segregation is
initiated at primary collection stage itself to use the
waste effectively. As an average we generate 100 to
150 kg per day from our waste. We have a separate
trainedteam inrollto take uptheservicedaily”

32. Flood and natural disaster management /
Earth Quake Resistance
1. Ramanujan IT City has been designed in accordance to the standard codes IS 456
and IS 875for structure and other imposed loads.
2. For Seismic structural stability it has been desi gned in accordance to the code
IS 1893:2002for Zone –IIIcriteria.
3. The Chennai Disaster resilience report classifies our site in Zone X, Wherein, the
overall resilience is slightly above average.
4. The Flood risk areas in this Zone is Velacherywhi ch is 5 Kmsfrom the site and
Adyarwhich is 3 kmsaway.
5. The site is also located at 2.25 Kmsfrom the Coastal Regulatory Zone (CRZ)
6. The approach road –OMR is at a height of +4.1 mabove MSL (Main sea level). The
internal roads are at +5.0 mabove MSL (0.9 m above road level)and the ground
level is at +5.52m(1.4 above road) hence suitable precautions have be en taken
while designing this campus to mitigate floods. The site is also equipped with
suitable storm water drains on the periphery.
7. The habitable area starts with the Amenity level which is at +11.82 m above MSL
(7.7 m above road level)hence more safety for the occupants.

33. Site Photographs during
Monsoons
Entry Gate & Internal Roads during heavy
rains in Dec’ 2015:
•No water stagnation inside the site.
•All Terrace & Surface water run offs
were managed by collection & proper

40. Landscape Features
nLandscape has played a major part in reducing
the Heat Island effect in the campus
nMajor portion of the podium area is covered
with greenery thereby reducing the heat
transmission to the lower floors and glare on to
the façade
nIn the Ground floor too care has been taken to
reduce the glare with extensive vertical
landscaped compound wall and planters along
the entire stretch
nThe top soil had been preserved at site during
excavation and same has been used for
landscape in site
nCare has been taken in choosing native species
of plants thereby reducing the water
requirement and survival of same.

41. Landscape Features
nRecycled water from STP is used for
landscape water requirement
nSprinklers have been installed to minimize
wastage of water
nRecycling of water in water bodies has also
helped in reducing the water consumption
in landscape
nMore than 90 % of the cars are located
undercoverinbasements.
nCare has been taken in choosing trees in
Ground level to seeto it the sametakes not
more than 5 years to grow full height and
give adequate cover to the open car parks
located in the external areas, thereby
reducingtheHeatIslandeffect.

42. Parking
-5 Levels of ample car parking –Reduces heat island effect as a result of covered car park
-Epoxy flooring to reduce wear and tear

43. •Rain water harvesting percolation pit with over flo w connection to the system with
micro filter.
•STP has been designed to handle 100% waste water fr om the campus.
•Water efficient flush & flow fixtures have been ado pted.
•Water recycling using treated water for the Toilet flush, landscape balance for the
cooling tower make up ,drift and evaporation losses (sewage recycled to the extent of
95 % )
•Variable speed secondary / tertiary pumps which ens ure that chilled water is supplied
according to demand.
