PROJECT AREA
2.0 INTRODUCTION
Central Province is one of the nine provinces of Sri Lanka, the first level administrative division of
the country. The provinces have existed since the 19th century but did not have any legal status
until 1987 when the 13th Amendment to the Constitution of Sri Lanka established provincial
councils. The Central Province is situated primarily in the central mountainous terrain of Sri
Lanka. It is the 6th largest province by area and is home to 2.5 million people. The province is
bordered by North Central
Province to the North, Uva
Province to the East, North
Western Province to the West
and Sabaragamuwa Province to
the South and West. The
Province's capital is Kandy.
The cities of Matale and Nuwara
Eliya are also located within the
Central Province. The province is
famous for its production of the
famous Ceylon tea, planted by
the British in the 1860s after a
devastating disease killed all the
coffee plantations in the
province. The Central Province
attracts many tourists, with hill
station towns such as Gampola,
Hatton and Nuwara Eliya. Figure 2 Index Map Showing Location of Housing Sites in Central & Uva Provinces of Sri Lanka

2.2. CLIMATIC CONDITIONS
The climate is cool, and many areas about 1500 metres often have chilly nights. The western
slopes are very wet, some places having almost 7000 mm of rain per year. The eastern slopes are
parts of the mid-dry zone as it is receiving rain only from North-Eastern monsoon. The
Temperatures range from 24C at Kandy to just 16C in Nuwara Eliya, which is located 1,889 m
above sea level. The highest mountains in Sri Lanka are located in the Central Province. The
terrain is mostly mountainous, with deep valleys cutting into it. The two main mountain regions
are the central massif and the Knuckles range to the east of Kandy.
2.3. DEMOGRAPHY

2.4. ECONOMIC PROFILE
The country's economy has traditionally been based on agriculture, which now contributes less
than 20% to the gross domestic product and employs about a third of the work force. The
emphasis is on export crops such as tea, rubber, and coconuts (all plantation-grown). Cinnamon,
cardamom, pepper, cloves, nutmeg, citronella, tobacco, cocoa, and coffee are also exported.
Rice, sugarcane, grains, pulses, oilseed, fruit, and vegetables are grown for local use and
consumption. Petroleum refining is important and amorphous graphite, precious and
semiprecious gems, mineral sands, clay, and limestone are mined. Port construction,
telecommunications, and offshore insurance and banking are also important industries. The
island's swift rivers have considerable hydroelectric potential.
The port of Colombo, on which most of the country's railroads converge, handles most of the
foreign trade. Exports include textiles and apparel, tea and spices, diamonds, emeralds, rubies,
coconut products, rubber goods, and fish. Textile fabrics, mineral products, petroleum,
foodstuffs, machinery, and transportation equipment are imported. The United States, India, and
Great Britain are the largest trading partners.

Footing Detail
Foundations are of types like isolated footing, combined footing, strip footing, raft footing, pile
foundations etc. They are selected based on structural requirement and soil conditions.
Reinforcement detailing of footing is as much important as site investigation for the type of
footing and structural design of footing.
Reinforcement Cover: The minimum thickness to main reinforcement in footing should
not be less than 50mm. Footing is in contact with earth surface directly, and 40mm for
external exposed face such as surface levelling PCC.
Minimum reinforcement and bar diameter: The minimum diameter for main
reinforcement should not be less than 10mm.
Detailing method of Isolated Footing: The isolated footing are generally square or
rectangular in plan based on structural requirement and forces acting on the column.
Reinforcement Distribution in Footing: In the case of two-way rectangular footings,
reinforcement is distributed across the full width of footing in long direction, however for
short direction, the reinforcement is distributed in the central band as per calculations
below. The rest reinforcement in short direction is distributed equally on both sides of
the central band.
