Scope of Work: I) Establishment of Ground controls by DGNSS: * Establishment of Ground Control Network with 1 CM absolute accuracy * Primary Control Static DGPS survey with 1 Hrs. uninterrupted observation (As per desired accuracy) control Point shall be Paint marked on permanent structures at the rate of 1-2 points per 250 Acres as per site requirements. * Additonal Benchmark Control Point usinn DGPS RTK at the rate of 8-10 Points per 250 Acres shall be paint marked on permanent structures/designed GCP Board to ensure control for full area. * Collecting the Rail Level available on station or SOI GTS benchmarks/ CORS network and transferring the reduced level to the primary control points and bench mark control points established II) As built Survey including topographical details using Drone based LiDAR System in Railway Colony Area. * Setup of Engineering grade RTK/PPK based LIDAR suitable to capturing various features in Railway Colony area, Flying Height between 70-100 mtr as per site requirement. Flying speed shall be suitable to capture the minimum Lidar point cloud density 100 Points per meter. Extra ares of 50 metre width should be covered as per the area of interest provided by Railway. * 3D Point Cloud Data capturing using engineering grade survey drone system including extraction of data for the whole area of interest. * Data Processing is to be done using High LiDAR processing software's including trajectory computation data aligning, merging, generating 3D point cloud, capturing of area feature. Development of the plans and other drawings III) Following Output Should be Delivered: * Processed 3D point cloud in LAS format - Accuracy of the Data Horizontal Accuracy shall be 2 cm- 5 cm RMSE and Vertical Accuracy shall be 2 cm - 5 cm RMSE. Georefrenced Orthophoto of the total area of interest in dwg/pdf format. Extraction of all the features such a s buildings, roads, water bodies, electric poles, bridges, parks, drains, encroachment area (if any) etc and submission of data in .shp format. Preparation of Topographical map and submission of data in dwg format. For (a) TATA, (b) CKP, (c) ROU, (d) JSG, (e) BNDM, (f) DPS, (g) ADTP, (h) SINI and (i) CBSA. Total 7124800.00
