2.0 PROJECT BACKGROUND 2.1
State Profile
2.1.1 The name West Bengal stands as a misnomer for the first timers as the state is actually located in the east of India. Having 9.1crores inhabitants, it is the fourth-most populous state in the country bordered by countries of Bangladesh, Nepal and Bhutan and the Indian states of Odisha, Jharkhand, Bihar, Sikkim and Assam. A major agricultural producer, West Bengal is the sixth largest contributor to India’s net domestic product. 2.1.2 West Bengal also boasts of rich flora and fauna having 15 wildlife sanctuaries and 5 national parks. Sundarban National Park a mangrove forest area in the Ganges delta which has been declared a biosphere reserve is one of the largest reserves for Royal Bengal Tiger. It also houses wide variety of bird, reptile and invertebrate species. 2.1.3 The proposed ROB lies in the Bishnupur town of Bankura district. It is also referred to as Mallabhum after the Malla rulers of this place who ruled during 17th and 18th century. Bishnupur is famous for its terracotta temples built by the Malla rulers. These temples are the best specimen of the classical style of Bengal architecture. Royal patronage in the region also gave rise to Bishnupur Gharana (school) of Hindustani Classical music in the late 18th century and the Bishnupur School of painting. The Bishnupur Gharana is rooted to Dhrupad style of music. Bishnupur is mostly plain land lying 59m above MSL. 2.1.4 There are many temples in this region which stand testimony to the exquisite craftsmanship of the artisans of the region. The temples were crafted from the local laterite and brick and covered with terracotta tiles depicting scenes from the epic Mahabharatha. Apart from the temples, terracotta pottery, artefacts and even jewellery made in this very traditional material is famous. The most famous of the terracotta products are the handmade beautiful jars, disks, horses, elephants, Ganesha and Nataraj. The potters here derive their inspiration from the glorious history of kings, soldiers and wars. Bishnupur is also known for its silk, particularly the Baluchari sarees. Bellmetalware, conch-shell and terracotta jewelry is also available here.

Sheet: 11 of 36 Date: February 2015 Revision: R0
Climate
3.3.1 The climate, especially in the upland tracts to the west, is much drier than in eastern or southern Bengal. From the beginning of March to early June, when the monsoon sets in, hot westerly winds prevail, the thermometer in the shade rising to around 45 °C. The westerly winds die down around sunset and allow cool winds to blow from the south. Nor'westers are frequent during this period and help to mitigate the excessive heat. 3.3.2 The monsoon months, June to September, are comparatively pleasant, as the weather is not as sultry as in other parts of Bengal. The total average rainfall is 1400mm, the bulk of the rain coming in the months of June to September. 3.3.3 Winters are pleasant with temperatures dropping down to below 27 °C in December. 3.4
Land use
3.4.1 Most of the land near the vicinity of project location is agricultural land or forest land. 3.5
Terrain Classification
3.5.1 The nature of terrain near the project location is plain in nature. 3.6
Geography
3.6.1 Bankura district has been described as the connecting link between the plains of Bengal on the east and Chhota Nagpur plateau on the west. The areas to the east and north-east are low lying alluvial plains, similar to predominating rice lands of Bengal. To the west the surface gradually rises, giving way to undulating country, interspersed with rocky hillocks. Much of the country is covered with jungles. 3.6.2 The area consists of two different tracts. The western portion marks the gradual descent from the table land of Chhota Nagpur to the delta of lower Bengal, consisting largely of spurs projecting from the western tableland and of low swelling ridges. However, there is no marked ridge of hills. In the central portion of the district there are rolling downs eventually merging with the alluvial plains. 3.6.3 The western part of the district has poor, ferruginous soil and hard beds of laterite with scrub jungles and sal woods. Long broken ridges with irregular patches of more recent alluvium have marks of seasonal cultivation. During the long dry season large extents of red soil with hardly any trees lend the country a scorched and dreary appearance. In the eastern part the eye constantly rests on wide expanses of rice fields, green in the rains but parched and dry in summer. 3.6.4 The rivers of the area flow from the north-east to the south-west in courses roughly parallel to one another. They are mostly hill streams, originating in the hills in the west. The rivers come down in floods after heavy rains and subside as rapidly as they rise. In summer, their sand beds are almost always dry. 3.6.5 The greater portion of the district consists of a rolling country covered by laterite and alluvium. While metamorphic or gneissose rocks are found to the extreme west, to the east there is a wide plain of recent alluvium. Strong massive runs of hornblendic varieties

stretch across the region in tolerably continuous lines, the general strike being nearly east and west. 3.6.6 The most characteristic geological feature of the district is the area of laterite and associated rocks of sand and gravel. At some places one finds hard beds of laterite. At other places it is decomposed and reorganized. Locally, the ferruginous rock is called kankar. The calcareous concretions, commonly used as the sources of lime, are known as ghutin. 3.7
Existing Road features The terrain at the project location is plain in nature. NH-60 at the project location consists of two lane carriageway having flexible pavement.
3.8
Existing Railway Crossing The level crossing at the project location is manned LC having a TVU of 36000 as on May, 2010. Approximately, 2 trains cross the said LC on a daily basis as per the data collected from railway cabin log book.
3.9
Existing Rail features Rail line lies approximately at level with the existing natural ground level. The cabin of level crossing lies on left side of the road. There is one rail line at the LC connecting Bishnupur station on one side to Birshamunda Halt on other side. Bishnupur railway station is located near to the level crossing.
3.10
Clearances required

General The prime objective of the management of Chaitanya Projects Consultancy Pvt. Ltd (CPCPL) an ISO 9001:2008 Certified Company is to provide services in a manner, which conforms to the contractual and regulatory requirements. In order to achieve this objective, it is the policy of CPCPL to maintain and implement an efficient and effective Quality Assurance Plan (QAP) with the full commitment of management for its ongoing vitality and relevance. Determination and conformance of our firm’s work to requirements is verified on the basis of objective evidence of quality.
6.2
Quality Goals and Objectives The objective of quality assurance is the continual improvement of the total delivery process to enhance quality and client satisfaction. Essentially, quality assurance describes the process of enforcing quality control standards. When quality assurance is wellimplemented, progressive improvement in terms of both reducing errors and omissions and increasing project usability and performance should be noted. Quality assurance should function as a "voice" for the client who expects a certain level of quality to be provided.
6.3
Concepts of Quality Assurance Quality Assurance (QA) refers to the operational activities put in place to control the quality of the service. These include such activities as providing clear decisions and directions, constant supervision by experienced individuals, immediate review of completed activities for accuracy and completeness, and accurate documentation of all decisions, assumptions, and recommendations.
6.4
Purpose of the QAP Quality control procedures, if followed, should ensure that the work is done correctly the first time. Essentially, QA is what is done to confirm that a QC program is effective and provides feedback upon which further development of the QC program can be made.
6.5
Elements of Quality Assurance Systems CPCPL has documented the QAP and shall maintain the same as a means of providing a design product that conforms to specified requirements.
6.5.1 Quality Plan Procedures - All work to be performed on the project shall be as defined by the appropriate personnel of the Consultant.
