5 1.0. EXECUTIVE SUMMARY The Andaman & Nicobar Islands in the Bay of Bengal are long and narrow broken chain aligned North- South. This cluster of Islands comprises of 572 Islands including big and small Islands and rocks. Little Andaman comes under South Andaman District. The total land area of Little Andaman is about 734 Sq. m. These groups of Islands are separated by the Bay of Bengal, Andaman Sea and internally through various other water stretches. Therefore to connect these groups of Islands water transport has become the major lifeline. It was observed that the lack of adequate transport facilities constituted the major bottleneck in the accelerated development of these Islands. In order to plan and provide a systematic development of Port and Navigational facilities which is the pre-requisite for any other development, the Govt. of India in 1965, set up the Andaman Lakshadweep Harbor Works Department (ALHW). Hence the Andaman Lakshadweep has proposed to construct a berthing head of 200 m length at additional approach of 159 m length instead of 400 m length of the total approach. The balance length of 50 m will be the solid approach for the approach jetty. Accordingly the estimate is framed for an amount of Rs Crore (Rupees forty Five crores and Fifty Five lakhs only) Figure 1: Project Site 5 P age

6 1.1. Engineering Consultants Andaman Lakshadweep Harbor Works (ALHW) department have got its own full-fledged team of Civil Engineers headed by Chief Engineer & Administrator as well as necessary Electrical and Mechanical Engineer. This department has sufficient expertise to do all the Designs, drawings, chalking out specifications, preparation, invitation and finalization of tenders for different types of works including wharf and allied structure and also whenever specialized Marine works are planned, this department obtains assistance from external sources viz. Indian Institute of Technology, Chennai, CWPRS, Pune etc. with a view to update the technical know-how and to implement latest technology in execution wherever required Demand and Traffic Analysis The Inter Island of Andaman & Nicobar Islands is rich in resources and there is scope for development of large trade, provided there is an inlet and outlet of cargo traffic through the Port. Therefore, the traffic projections for future are only indicative. The expected tourism is a blossoming factor in increase of traffic. Hence this proposed infrastructure by ALHW is very important to address the increasing traffic and the prospective of overall development of the island INTRODUCTION OF THE PROJECT The Andaman and Nicobar Islands one of the seven union territories of India, are a group of islands at the juncture of the Bay of Bengal and Andaman Sea located between 6 degree and 14 degree North Latitude & 92 degree East Longitude. The rich resources these islands posses are not utilized to its optimum level due to the lack of connectivity within the large number of cluster islands as well as the rest of the world. A well-knit and coordinated Port/ Shipping system play an important role in the sustained growth of the Islands. The need for Ports became more pronounced in these Islands in view of the accelerated development. Accordingly the estimate is framed for an amount of Rs Crore (Rupees forty Five crore and Fifty Five lakhs only) 6 P age

8 2.1. Project Proponent The Andaman Lakshadweep Harbor Works (ALHW) was set up by the Ministry of Surface transport in October 1965 and entrusted with the responsibility of formulating and implementing the programmes of the Government for providing Ports and Harbor structures including allied facilities in the Andaman and Nicobar Islands and Lakshadweep. The need for Ports became more pronounced in these Islands in view of the accelerated development programs proposed by the Government during the sixties. The infrastructure, therefore, had to be fully planned properly and in advance. Here experts have laid the foundation for development of Port facilities by the Andaman Lakshadweep Harbor works in later dates Brief Description of Nature of the Project The proposed project is development of Hut bay in Little Andaman by the Construction of additional approach & berthing wharf. The construction of a berthing head of 200 m length at additional approach of 159 m length instead of 400 m length of the total approach. The balance length of 50 m will be the solid approach for the approach jetty. The proposed project falls under category 7(e) Ports, harbors, break waters, dredging of the Schedule vide EIA notification 2006 amended to date involving preparation of Environment Impact Assessment study and Environment Management Plan. However general condition is not applicable to this project. This project is independent and does not link with other project/s which attracts directly or indirectly any provisions of schedule of EIA notification 2006 amended to date Need for Project Hut Bay is the Administrative head of Little Andaman Island and hence the same is the center for trade, communication, shipping and various other fields of activities. Ships bringing cargo and passenger for the Inter Island call at Hut Bay. The entire Island shipping services with Southern group of Island are operated from the Port Blair. Due to cyclones and bad weather, the wave splashes over the Breakwater causing traffic interruption to approach the wharf; as a result the port operation is hampering and causing isolation to the inhabitants. At present, Deep Water Wharf is available for all purpose at Hut Bay as the only life line. In order to make it all time functional, it is essential to develop a separate approach for the existing wharf from the shore. The additional wharf would cater the future requirement and increasing growth of traffic. Accordingly, an approach jetty founded on bored pile structure is proposed. 8 P age

9 2.4. Demand-Supply Gap i. The total inward and outward passenger and cargo traffic at Hut Bay was 21,504 Nos. & 9239 MT respectively during 1989 and this has increased to Nos. and MT in Table 1: Details of inward and outward passenger traffic at hut bay * * * * Source-Port Management Board, Port Blair Table 2: Details of cargo traffic at hut bay * * * * Source-Port Management Board, Port Blair ii. In pace with this, the number of ships plying in Andaman waters has also increased manifold over the past few years. At present there are 77 ships operating in this area and this is expected in increase to 123 by Imports vs. Indigenous production Little Andaman consists plantations of Coconut and Arecanut with prospects for development of rubber, tea, coffee, and cashew nuts plantations. Recently Red palm oil has come up as an important crop in the island. Plantation of fruits like pineapple, papaya, lemon, and oranges are being greatly boosted in recent years. Processing and manufacturing units have are already in place and will grow further around these plantation and agricultural products and is a blooming fishing industry. Manufacturing of rubber products like bicycles and scooter tyres is encouraged. Food processing units including canning, have excellent prospects for development. The general cargo traffic handled by the port with the existing facilities consists of food grains, sugar, and various other edible items, various plants and machineries, construction materials, timber logs, plywood, food grains, sugar etc Employment Generation During construction phase, employment opportunities for 25 persons would be generated. The facility is expected to generate employment opportunities for 10 persons during the operation phase. 9 P age

16 3.2. Project Location The proposed project is located at Hut Bay in Little Andaman, Andaman and Nicobar confined within Latitude 10 35'17.23"N and Longitude 92 33'42.01"E. The project is situated at approximately 0.18 km away from State Highway 1 connecting the two major settlements Ram Krishnapur approximately 12 km to the north and Indira Bazar approximately 2 km to the south. The Airport is around 120 km away in Port Blair. There would be no land acquisition required as the project requires a very small amount of land and also it is an expansion approach to the wharf already existing. The project extends into the sea and hence CRZ clearance would be required which would be taken. Figure 8: Project Location 16 P age

17 3.3. Alternative Site As the proposed project is an expansion of an additional approach to the existing Wharf which was damaged during Tsunami hence no other alternative site were examined Size and Magnitude of Operation At present the total number of passenger incoming and outgoing is accounted to in 2016 that have shown a significant increase since the last 3 years which were in Similarly there has been a significant increase in handling of cargo from T in 2014 to T in Handling of cargos include construction materials, plants and machineries, timber logs, plywood, food grains, sugar and other edible items. In addition to this Naval, Coasts guards, oil tankers, tourist liners and other departmental vessels are also plying these areas Project Description Dredging / Excavation Pilling Laying of Slabs Construction of additional wharf/ additional approach to berthing wharf/ retaining wall with backfilling to form approach road 3.6.

21 Rubble bound breakwaters of 1200 m length wharf 225m x 33m Passenger shelter Godowns Port Fire Station And other amenities Soil Classification The soils of Little Andaman are derived from the sedimentary rocks like Limestone, Coral sand, Mud stone etc. These soils are well drained with rapid permeability and are texturally classified as sandy, loamy sand, sandy loam. Plantation crops like, Coconut, arecanut, guava; mango, banana, sapota etc. are very well grown in such soils. Due to coarse soil structure there is no chance of water logging even during rainy season while high permeability also assures good moisture during dry spells and facilitates luxuriant growth of coconut, arecanut and root crops along the coastal stretches Geomorphology The size, shape and height of a islands control the occurrence and movement of both surface and ground water resources to a considerable extent. The islands in South Andaman District have varied topographical features. Deep inlets and creeks are formed by the submerged valleys. Flat lands are few. Coral reefs surround most of the Islands. The islands generally feature a mountainous terrain with long ranges of hills and narrow valleys. South Andaman District can be divided into the following five broad units. 1. Moderate to steep hill ranges having low to moderate heights. 2. Narrow intermontane valleys 3. Narrow, gently sloping coastal tracts including swamps 4. Islands basically made of Coralline material (atoll) or having Clay-mudstone-chalk stone sequence in higher elevations with preponderance of coralline deposit in the low lying areas with very gentle slope and relatively wide coast encircling the islands. 5. Rugged coast devoid of beaches Climatic Conditions The climate of these islands is described as tropical climate. These islands are situated in the hot or torrid zone. Nearly 86 percent of the total area in these islands is covered by forests. There are only two seasons viz. the rainy season and the summer season and virtually there is no winter. However, moderate cold climate also prevails in some parts of the Islands. Islands are visited by South-West monsoon and North-East monsoon during the period of May to September and from October to December respectively. This leaves a fair season of 4 months only. Average annual rainfall is 3000 mm. The mean relative humidity is 79%. The mean minimum temperature is 23.8 degree Celsius. The wind 21 P age

22 speed during the monsoon can be at the rate of 40 to 120 km per hour and an incessant heavy rain is observed. The tide height is approximately 2.5m high Social Infrastructure The area consists of jus two densely populated areas indicating that not many social infrastructures are available in and around the area, some of them are as follows. Light House 5.5 km to the south Aasthan Resort 6 km to the north. V Vet Restaurant 10 km to the west 5.0. PLANNING BRIEF 5.1. Planning Concept The proposed project is estimated to be completed in 30 months. The work to be carried out during construction has been bifurcated into three years.

Population Projection The total population of Little Andaman as per 2011 census is 18823, of which males are 9964 & females are Land Use Planning The proposed project is almost entirely into the marine waters and very small quantity of land will be used. This is a flat land which is going to be cleared and backfilled to construct of a solid approach Assessment of Infrastructure Demand The entire area is underdeveloped with a very few basic infrastructure. The area is devoid of basic sanitary, health care, education, facilities for the local habitants. A state highway runs across the project area other than that there are not many well developed roads or adequate mode of transport. Hence for the continued growth of the area provision of such basic facilities are very important PROPOSED INFRASTRUCTURE The objective of the project is to produce a balanced port complex to serve forecast cargo demands. However, before defining and evaluating specific alternatives, port development objectives need to be outlined. The primary goal of the Master Plan is to define a development concept which allows for the port to be marketed, developed, and safely operated for the betterment of the region and its users. With this in mind, the following development objectives have been defined for this planning effort: Maintain an attractive, efficient facility in accordance with government, state, and local regulations. Develop facilities to efficiently serve general users and encourage increased use of the port, including business and corporate activity. Ensure that any recommended future development is environmentally compatible. Enhance local economic development through maximizing the use of available property. Identify opportunities for further development of the area. 23 P age

24 7.0. REHABILITATION AND RESETTLEMENT Area required for the expansion falls under CRZ land (no development is proposed) where no habitation is present. Hence, no Resettlement and Rehabilitation is envisaged for the proposed expansion of wharf PROJECT SCHEDULE AND COST ESTIMATE The entire work is programmed to be completed in 30 months from the date of Administrative Approval and Expenditure Sanction. It is proposed to operate theoretically one shift of work in a day. In case of outturn getting delayed due to unforeseen causes and break down of machinery, the shortfall will be adjusted by working 1 ½ to 2 shifts as and when required, thus completing the project in time. This assumption has been made based on actual condition, which will give a realistic time schedule OPERATING REQUIREMENT AND COSTS Table 6: Year wise bifurcation of funds S.No Item of work Cost in (Rs.

Construction of additional approach to berthing per annum wharf at Hut Bay in Little Andaman. 3. Providing retaining wall with back-filling to per annum 0.88 form approach road for connecting wharf at hut bay in little andaman Total Revenue and Income of the Project The main source of revenue for this project is charges levied on different services offered by the Port to different users. It is anticipated that the Port is likely to generate direct income of ` Lakhs per annum Indirect Revenue The Island has great potential for attracting Foreign & Local tourist which will provide employment to the local population. This is likely to generate indirect income post completion of the project by offering different services. It is anticipated that the Port is likely to generate indirect income of 775 Lakhs per annum Internal Revenue Return The internal rate of return (IRR) or economic rate of return (ERR) is a rate of return used in capital budgeting to measure and compare the profitability of investments. An investment is considered 25 P age

26 acceptable if its internal rate of return is greater than an established minimum acceptable rate of return or cost of capital. The economy of Andaman & Nicobar Island consists of coconut cultivation, fishing and tourism. There is no major/small industrial establishment in this Island and construction work is very much limited. The port available in this Island is very small and thus revenue accumulated from this port is meager. The investment in this Island made by the Government of India is for the overall improvement of living conditions of local people on account of a welfare measures only and in turn the Government is not expecting a Revenue Return The internal rate of return (IRR) expected from the project Construction of additional approach for the Hut Bay Wharf in Little Andaman is NIL only CONCLUSION Based on the fact that in the North-East bad weather condition, the water splashes across the approach and the wharf becomes unapproachable. This is the only landing place available in the Little Andaman & shipping being the life line, it is proposed to construct an additional approach with berthing head from the shore at the lee side of the existing breakwater so as to provide round the year connectivity and uninterrupted port operation. 26 P age
