SECTION 2.0

SCOPE OF WORK 2.0 GENERAL

The work mainly comprises of topographical survey and final location survey for Techno-Economic Feasibility Study and preparation of DPR for the fast harbor suburban Rail corridor along CSTM - Vashi - Panvel Railway section (60km) of Central Railway, Mumbai or as decided by the Engineer-in-Charge. Activities to be performed are as follows: Fixing the pair of main control points with the help of DGPS along the proposed

alignment at an interval of 5 Km (maximum). Topographical Survey along the proposed route alignment including precise

Leveling of Control points & Profile Leveling. Precise leveling and preparation of Longitudinal Section along centre line of

proposed alignment. Topographical survey for providing approach roads, terminal station, traffic

integration area, Depot etc. Final location survey including fixing of pillar after finalization of alignment.

2.1 WORK CONTENT 2.1.1 Topographical Survey

The work involves carrying out a detailed engineering topographic survey along the existing sub urban Rail corridor not less than 100m wide or up to Railway boundary/built up lines including existing stations/yards showing setback of 15m minimum beyond Railway boundary (whichever is more) or as decided by Engineer-in-charge. Generally, the proposed fast harbour sub-urban corridor would be running along the existing Railway track from CSTM - Vashi - Panvel of Central Railway with connectivity to proposed Navi Mumbai Airport. However, as per site requirement, the alternative alignment from CSTM to Rey Road station may be considered along the D. Mello or through MbPT area. Thus, survey may be carried along the existing road wherever required as decided by Engineer-in-charge. . i) As the suburban route is highly congested in terms of train operation hence,

contractor should follow all safety regulations while survey work and to the extent possible run the traverse for fixing the intermediate traverse points between DGPS control points on both side of the corridor generally along the railway boundary, so that maximum details can be taken up with minimum disturbance. Contractor should also make necessary arrangement to work in night hours also.

ii) Atleast four teams (Two Surveyor in each team) shall be deployed at site for

topographical and final location survey work till its final completion.



iii) The main DGPS control points and intermediate traverse point shall be fixed

A rod of 20 mm diameter and 350 mm long of Mild Steel shall be provided at the center of pillar to mark location of traverse station. Top of control point shall be at same level as that of adjoining ground level. Each control point shall be painted to mark its number. It is deemed that cost of control points is included in item No.1&2 of BOQ. No extra payment shall be made on this account. The all control points shall be maintained until survey is taken over by RITES till the completion of final location survey.

iv) Before the commencement of Topographical Survey, the contractor has to

establish main control points with the help of DGPS not more than five km interval along the corridor and then run closed traverse for fixing the intermediate traverse points at suitable interval (maximum 500m) for detailed topographical survey work. Each intermediate traverse point will be finalized after taking mean value of observed coordinates from 3 successive triangulation control point and minimum two sets of observations. The accuracy of intermediate control point should be 2mm. For main control points, the contractor has to maintain the leaner accuracy 1: 50000 between the DGPS point. The contractor has to provide all raw data and calculations as and when required by EngineerinCharge of its representative verification.

coordinates supplied by survey of India. The drawing shall be generated on UTM coordinate system only. However, contractor has to provide latitude, longitude and TM coordinates also.

vi) The main DGPS control points and intermediate traverse point shall be fixed

on cement concrete pillars made of grade M-15 (1:2:4), rectangular in shape and size of 300mm x 300mm x 600mm. A rod of 20 mm diameter and 350 mm long of Mild Steel shall be provided at the center of pillar to mark location of traverse station. Top of control point shall be at same level as that of adjoining ground level. Each control point shall be painted to mark its number. It is deemed that cost of control points is included in item No.1&2 of BOQ. No extra payment shall be made on this account. The all control points shall be maintained until survey is taken over by RITES till the completion of final location survey.
