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




2.1. LOCATION OF HOUSING SITES

Kandy, Nuwara Eliya and Hatton regions are situated in Central Province and Badulla region is

situated in Uva Province. With reference to the above cited Project, WAPCOS team visited Sri

Lanka from 7th October, 2014 to 18th October, 2014 to have first-hand information of Housing

Project Sites, Meeting and discussions with officials of High Commission of India (HCI) and officials

of Plantation Human Development Trust (PHDT) and various concerned officials of Tea Estates of

the Project Area.

Figure 3 LOCATION OF HOUSING SITES IN CENTRAL & UVA PROVINCES OF SRI LANKA




The team visited and collected the information from 08.10.14 to 14.10.14 for 16 Tea Estates

spreading over Nuwara Eliya and Badulla Districts of Central and Uva Provinces along with PHDT

officials.

After completing the Site Visit, a meeting was held on 16th October, 2014 along with the Honble

Minister, Ministry of Livestock and Rural Community Development, Government of Sri Lanka, all

the Officials of Tea Estates, PHDT Officials and Second Secretary, HCI to discuss the various issues

across the table.

It was emphasized in the meeting that the Tea Estate should undertake the Topographic Surveys

to decide on the benching of the Housing sites, representative soil investigations to arrive at the

soil bearing capacity (SBC) to decide the foundation, which would be required for finalizing the

DPR and Drawings. WAPCOS requested for the following data to be made available preferably by

end of November, 2014.

Perimeter survey of the area of the proposed housing plots.

NBRO report of the proposed housing sites (English Version, if available)

Topographic survey (Contour survey) of the proposed housing sites

Soil investigations report of the proposed housing sites

Beneficiary list of these housing scheme from the tea estates

Subsequently, as per PHDT letter date 03.12.15 received through Email from Second Secretary,

HCI, Colombo it was suggested by M/s. PHDT to commence the project for 906 Number of houses

immediately based on the survey work and NBRO Report Completed/ under progress.

WAPCOS team had undertaken the site visit to Sri Lanka from 17th December, 2014 to 23rd

December, 2014. However, during the visit, it was observed the none of the Tea Estate has

completed the contour survey which has already been mentioned to all the Tea Estates officials

during the above cited meeting held on 16th November, 2014.




WAPCOS Team along with PHDT officials visited all the project sites for 2070 houses as being

prioritized by PHDT in order to emphasize the ongoing survey team at project site/ tea estate

officials regarding necessity and importance of contour survey and features to be included in the

contour survey.

The officials of HCI and WAPCOS Team had the meeting with PHDT officials. It was decided during

the meeting that NBRO Report (in English), Survey Data and Beneficiary List for 2070 houses shall

be furnished to WAPCOS on and before 10th January, 2015.

WAPCOS received the Survey Data of 1192 Housing Units in the Month of February, 2015. Also a

mail stating the revised list of 1409 houses to be considered in Phase-I was received. Based on

the Survey Data received, WAPCOS prepared and submitted the Site Planning and Cost

Estimation of Site development of 604 Housing Units, Architectural Plan of Housing Units to High

Commission of India, Colombo, during first week of April 2015.

In order to finalize the Architectural Plan of Housing Units, Site Planning, Cost Estimate of Housing

Units and Site Development Cost, WAPCOS team visited Sri Lanka from 5th April-10th April, 2015.

During the visit, WAPCOS team had discussions and meeting with the Second Secretary, High

Commission of India, Colombo, The Secretary, Ministry of Plantation Infrastructure

Development, Government of Sri Lanka and the Officials of PHDT, Sri Lanka.

Site Development Works includes Site Clearance, Bench Cutting, Construction of Road Pavement,

Storm Water Drain, External Water supply Line, and Electrification Works & Street Lighting. The

following aspects observed needs to be considered:

The Site Development Cost shall vary from site to site depending on terrain / contours.

Therefore every site will have different site development cost.




The Basic community facilities such as school, dispensary, bus stand, water supply,

electricity, sewerage needs to be addressed separately for these housing units, by Govt.

of Sri Lanka.

The Site Development and Construction of Housing Units shall be carried out under a

single tender package for each site for effective and faster execution of work

Confirmatory Boreholes needs to be undertaken for each tea estate for assessing the

geotechnical Data and Soil Property to confirm the soil bearing capacity (SBC).

Based on the availability of Survey data the 1134 housing Units will be included under Phase-I.

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

2.3.1. Population and Density

As per 2007 census, the population of Central Province was 2599000 peoples spreading over an

area of 5575 Sq. km and the density of the area is 466.2 per Sq. km. The population is a mixture

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.

3.3 GEOTECHNICAL DATA- NBRO REPORT

National Building Research Organization (NBRO) under the Ministry of Disaster Management is

the national focal point of Sri Lanka for all landslide related studies and services. The Geotechnical

Investigations through NBRO have been conducted for proposed housing sites. Based on these

NBRO reports and site conditions, the sites have been identified by Tea Estate and PHDT. The

NBRO reports of above mentioned sites is under the translation by PHDT. However a sample

NBRO report has been enclosed as Annex-II

The Geotechnical Investigations gives an overview of the site pertaining to proposed structures.

The Investigations will elaborate the terrain, prior known land use, general area geology,

groundwater etc. The various explorations and tests are translated into specific loading criteria,

PROJECT PROPOSALS

4.0 GENERAL

The scope of the assignment covers the Project Management Consultancy Services for design and

Construction supervision of 4000 housing units in Central and Uva Province. However based on

the site availability and its conditions, 862 housing units are being proposed in Phase-I.

The works mainly consists of construction of housing units, infrastructure works like road,

drainage, water supply, sewerage, landscaping, etc. The proposals for the planning and designing

of the project area are prepared and presented in this Chapter.

The work undertaken by WAPCOS from Oct 2014 (i.e. signing of agreement) was presented to

the monitoring committee during the meeting held on 09.05.14 at HCI, Colombo. The officials

from PHDT were also present. During the meeting it was discussed that under Phase-I, 1134

number of houses shall be constructed spread over at 9 Division of 5 Estates in Central and Uva

Province. Initially WAPCOS has prepared the site layouts for 1034 houses. However, based on the

site conditions and availability of area, the 862 number of housing units are being proposed.

The area proposed for each housing unit is 550 sq.ft. of built up area with total plot area of

7 perches ( 1905.75 Sq.ft) per house as per local requirement (1 perch = 272.25 sq.ft) ,this area

is excluding common area for community infrastructure.

However, each house will require minimum approx. 10 perches which will include internal roads

for planning purpose.

Tentative cost of each housing unit of 550 sq.ft works out to LKR 13.00 Lakhs. The housing cost

does not include Common Water Supply from Source to these individual houses, Common Power

Supply from Source to these individual houses, Access Road, Internal Roads, Common Street

lighting (solar lighting with panels) and Storm Water Drainage System.

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.
