Conducting Aerial Topographical Survey with DGPS integrated RTK/PPK UAS DRONE basedphotogrammetric and Lidar to capture ground features and assets along the given alignment 1 including Yards. TerrestrialBased Lidar System shall also be conducted to get uniform accuracy and data through out on the final approvedalignment. Survey will be done for width of around 100m. In mid-section and around 250 m in yard. However finalwidth requirement shall be as approved by Engineer-in-charge. Following output should be delivered: 1. Topographicalbase map in AutoCAD format of 1:500 scale having all the naturals & manmade features such as buildings, road, tracks,platforms, walls, yards boundaries, fences, signals, electrical mast, FOBs, LCs, RUB/ROBs etc. In .DWG or .DXF format.2. Contours at an interval of 50 cm in DWG or DXF format. 3. Digital Elevation Model of 1m resolution in ASCII formatand DWG format. 4. 3cm resolution (GSD) Ortho- photo in ECW or TIFF format which can be opened in CAD. 5. List ofControl points established onto the Ground using DGPS (every 2 km as primary control points on existing permanentStructures.) 6. RTK (every 250 m) along with their Latitude, Longitude and elevation. 7. NSSDA report showingaccuracy achieved in comparison to control points established. 8. Digital Terrain Model showing accuracy achieved incomparison to control points established. 9. Preparation and supplying of Yard Plans (ESPs) of various Stations alongthe alignment showing proposed position of track and related structures based on concept plan on Auto Cad and submitin CD along with miniature A4 size yard diagram. 10. The levels shall be provided at every 25 M interval and each 5 Mfor cross section upto 30 M beyond toe/edge of bank/cutting of BG formation for cross section and must be shown inplan. 11. The Reduced level/Rail level shall be connected with standard bench mark. 12. Longitudinal section (L-Section)/Cross section and alignment plan will be prepared on computer in Auto CAD and submitted in soft copy as wellas hard copy. 13. Index plan and index section in soft copy as well as hard copy. 14. Processed 3D point cloud in LASformat. The item also include staking of approved alignment with RCC Pillars (150 x 150x 900mm size with 300mmprojected above ground level) at an interval of 500m, (with wooden pegs 50 x 50 x 450mm size) at every 20m wheretrack is away from the existing track or where it is advised by Engineer-in-charge. (Cost of wooden pegs is inclusive).The RCC Pillars shall also be fixed on curves indicating transition portion, apex point, crown of curve, beginning and endpoint of circular curves, (5 locations for each curve) at major bridges two pillars one or either side, including submittinglist of distance and coordinates of centre line of proposed BG line from centre line of existing BG line at every 25minterval. He shall also submit the list of existing infringement to the proposed BG alignment as per latest SOD for BG.The proforma for the same shall be approved by Engineer-in-charge. Payment Schedule for Item No.1 of Schedule : A.70% payment shall be made on submission of the report. B. 30% payment shall be made on approval of the work bythe Railways.
