Section 5: Terms of Reference (TOR)

1. Background:

Nganglam Drungkhag under Pemagatshel Dzongkhag has 3 Geogs namely Norbugang (442 HH), Chhokorling (256 HH) and Dechheling (513 HH). The total population of Nganglam is around 14,117. Its elevation ranges from 200m to 2200m and the climate varies from sub- tropical to cool temperate.

The major existing government, corporate and private infrastructures and facilities in Nganglam include, but not limited to, Drungkhag Administration, BHU Grade I, RBA, RBP, Middle Secondary School, RNR Range Office, Helipad, Dungsam Cement Corporation Limited, Bhutan Telecom, Druk Satair Quarry, Bhutan Post, RICB, Bhutan Oil Distributor, Dungsam Polymers and Druk Gypsum.

Nganglam is strategically located in the Eastern Bhutan in terms of its distance to the 6 Eastern Districts. With the completion of the construction of the following road networks, Nganglam would be within a day’s drive to the 6 Eastern Districts. Nganglam-Dewathang (75 km), Nganglam-Gyalpoizhing (74 km),Nganglam-Panbang (55 km), Nganglam-Pemagatshel (120 km) and Nganglam is close to the Indian market, namely Partshala and Potali which are 48 km and 38 km away, respectively. To facilitate trade and commerce, there is a proposal from the Indian side to connect Potali by railway. This connectivity would not only further reinforce Nganglam’s access to Indian market, but it would also enhance its access to Bangladesh.

As Nganglam is strategically located and within a day’s reach to the six Eastern Districts and part of central Bhutan and also because of its proximity to the India and Bangladesh, there is a high potential in setting up a dry-port to clear customs and store in-coming and out- going goods. Such facility would facilitate and promote trade and commerce in the Eastern Bhutan, in particular.

The existence of large stretch of cultivable land and favorable sub- tropical climate to produce pineapple, passion fruit, mandarin, banana, and sugarcane on a large scale and Nganglam’s close proximity to India and Bangladesh demonstrate the commercial viability of agro- business in Nganglam. Further, Nganglam can also source such agro-based raw materials from Monggar which produces them in large quantity.

A large stretch of government land in Rinchenthang, Nganglam suitable for Regional Hub development overlaps with Biological Corridor (BC-5), which is critical for the free movement of animals between Royal Manas National Park (RMNP) and Khaling Wildlife Sanctuary (KWS). Rinchenthang was also earmarked for new Nganglam Township for which Local Area Plan (LAP) was prepared and two water distribution tanks with capacity to supply water to 50,000 people were constructed.

Prior to the preparation of Regional Hub development plan in Nganglam, it is immensely essential to have details topographical datasets. Therefore, the Department of Human Settlement (DHS) intends to carry out detailed topographical survey (ground survey) using total station for the proposed study area. 2. Descriptions of the proposed Survey Area:

The total area identified to conduct topographical survey is about 1236.00 Acre (≈ 5.0 Sq.Km). It consists of about 60% forest coverage mostly with shrubs and bushes. The proposed survey boundary starts from Bypass Road (under construction) in the South-East, following the Biological Corridor till it reaches Nganglam-Partsala existing road.

Follows along the road and crosses the streams below Jazama. It follows along the existing access road leading to Tangzema. Connects to stream(west of Tangzema), follows along the stream covering all the settlement of Tangzema. It joins in the confluence of streams above Sa-tsalo. Follows above Sa-tsalo settlement and connects to Nganglam Lower Secondary School till it reaches to Dungkhag Guest House and covers all the existing town and crosses Kirung Ri in the North. From North, it covers Higher Secondary School and follows along forest boundary till it reaches to the centre of existing town and follows along the Nganglam-Deothang proposed highway (under construction) and covers RBA campus in the East. It follows along the thick forest above Jazama and connects to Nganglam-Partsala road and covers the settlement above the road and follows along the existing road till it reaches to Bypass road (under construction) in the South East.

For details , refer the image map (Reference Map-1) for the proposed survey area. 3. Objectives:

To carryout topographic survey for the area identified for Regional Development to facilitate preparation of Development Plan of Regional Hub of Nganglam. The assignment includes, i) establishment of permanent ground control points and ii) Detail topographic survey (as per scope of the work with the scale 1: 1000)

4. Scope of Work:

The scope of the work of the survey includes the following:

4.1. Control Points. Establishment of bench mark (horizontal and vertical control points) on the ground at strategic locations to carry out detailed survey.

Sufficient permanent control points must be constructed at strategic places and coordinated both horizontally and vertically.

Control points should be established evenly/uniformly throughout the survey area. If the control points are established using GPS, survey stations should have inter visibility at least between two control points.

The coordinates system shall be based on National Reference System (Drukref Local Coordinate System)

The accuracy of the control points should be of secondary/tertiary level accuracy.

The structure of the survey stations should be as per the requirement of the client.

Upon completion of ground control survey, a report consisting of description of the station and coordinates (X, Y, Z) and traverse /control network maps should be submitted to the procuring agency along with the inception report before starting the detail survey. The detail survey should commence only upon mutual acceptance of the accuracy of the control point.

4.2. Detailed Survey.

All notable physical features both man-made and natural which shall be, but not limited to, buildings, monuments, burial grounds, cremation grounds, places of worship, posts,

Section 5 : Terms of Reference 50

pipelines, existing roads and stream/ river/ canal crossings, cross-drainage structures, septic tanks, manholes etc. which are found on the ground should be surveyed.

4.3. Contour Survey.

Contour survey must be carried out in consideration to finally generate a map/data with contour interval of 1 meter. The spot heights should also be picked up as to incorporate any elevation variation of 1meter on the ground considering Bank Top and Bank Toe (bunds). Spot heights should also be given at a grid mesh of 5-10M depending upon the terrain but wherever there is change of elevation of the ground, spot heights should be taken to indicate it.

4.4. Instruments and software requirement

Precise GPS instruments shall be used for the control points if NLC’s control points do not exist on the ground. Total station with angular accuracy of 2”/3” and distance accuracy of 1.5 mm+2 ppm should be used for the detailed survey. LISCAD and AutoCAD Software of compatible versions shall be used for data processing.

4.5. Work Process

Control points should be established within the survey area with the accuracy of secondary/tertiary level control points by means of traverse using the control points. Upon completion of the provision of the control point, the detail survey should be carried out.

The data editing should be carried out daily basis in LISCAD See file and update regularly in the field.

Upon completion of the detail survey, the data set should be finally edited in LISCAD See file and export to AutoCAD drawing. The final edited survey data/map should be delivered both in LISCAD See. file and AutoCAD drawing with proper colour codes and layers.
