TECHNO-ECONOMIC SURVEY AND PREPARATION OF DPR FOR PANVEL-DIVA-VASAI-VIRAR CORRIDOR 44.. CIIVIILL ENGGIINEERRIING 4.0 INTRODUCTION • This chapter covers the alignment proposals for the new suburban corridor on Virar- Vasai-Diva-Panvel section on Central & Western Railway, Mumbai ( Figure 1 ). • The collection of the existing topographic features to the required degree of accuracy was an important activity for the successful design of the proposed new suburban corridor. The route was identified contemplating the existing surface area and elevated design wherever necessary utilizing to the maximum extent of available Railway land. The Topographical Survey was conducted covering complete Railways Area along the proposed corridor and 20 m strip of private area has been also surveyed on both side of Railway Land Boundary, wherever found feasible. The proposed alignment of DFCCIL running almost parallel from Panvel up to Juichandra has also been studied/marked to avoid any infringements. 4.1 ENGINEERING SURVEY 4.1.1 Introduction • A survey team led by the team leader, conducted a reconnaissance survey along the corridor to study and find out any bottlenecks to be tackled during the field work • Topographical survey team headed by a Manager level officer was deputed to ensure the quality and progress of work. Monitoring of day to day survey progress and quality was done to ensure the collection of all ground features as per scope of work. • The Survey work was carried out along the existing railway corridor between VR - Vasai – Diva – Panvel (70 km) as well as for the the area between Nilaje-Kopar along the proposed DFC alignment, survey for proposed location of depot along the existing railway corridor between Kalwar–Dunge village. 4.1.2 Survey Methodology • For maintaining high precision in picking up maximum details in available time, the coordinates for the traverse points were fixed by using the GPS (Global Position System) between Vasai to Panvel and closed traversing was carried out between GPS point by using Total station with one second accuracy and SOKKIA Auto levels with 1 mm accuracy for levelling works. The GPS station fixed with the help of DGPS are tabulated in Table 4.1.
