AERIAL LIDAR SURVEY USING AIRCRAFT/HELICOPTER An Aerial LiDAR survey using an aircraft or helicopter, complemented by aerial photography, shall be conducted for the area of interest covering the proposed alignment. The survey includes the identification and establishment of control points (Horizontal control by DGPS Triangulated Network and Vertical control by leveling w.r.t. GTS Benchmark), hydrological survey for minor bridges, river and water body crossings, as per the scope of work and technical specifications between Hyderabad–Chennai (705 km). Data capture will be carried out for a 600m-wide corridor (i.e., 300m on each side of the proposed alignment). However, data processing will be conducted for a 100m-wide corridor (i.e., 50m on either side of the alignment). Preparation of 3-D topograpgical Map as per technical specifications for design of final aligment. Additionally, the scope involves the supply of an all-in-one desktop PC, data processing, and submission of all deliverables, including the identification and establishment of control points as per the scope of work and technical specifications outlined in the tender document. Supply of two numbers of All in one Desktop PC (HP, DELL, ASUS) - i9/i7, 12th generation processor with minimum 32 GB DDR4 RAM, 1 TB SSD, Intel UHD 770/NVIDIA graphics card or higher along with windows latest operating system, with 3 years onsite warranty, to suit the verification and utilization of all LIDAR processed data and outputs along with all licensed softwares (3D Civil/Autocad, Open Rail, Global mapper, Adobe Professional, and any other software required for the project) (except required for processing of LIDAR raw data) required for the project with validity for 1 year from the actual date of completion of the project.Video file merged for entire length of corridor in 4k quality in mp4 format with a Speacial video player with 4K Monitor & Player for viewing the videos.

List of all the permanent Control Points and reference Pillars with coordinated (in grid and ground system) in Tabular form. All the drawings are to be made with a scale of 1:1000 or as per the instructions of client. The locations of Permanent Control Points, Reference pillars, and GTS benchmarks shall be shown with X,Y,Z co-ordinates various maps, plans etc.For all other activirties and deliverables please refer the specifications and Tender Document. Payment Terms: 90% of the payment will be released upon completion of fieldwork and submission of data and reports. 10% of the payment will be released upon acceptance by the Railway.

PERMANENT CONTROL (CP) POINT PILLARS The erection of cast in-situ RCC pillars (1:1:2) of size 500mm × 500mm × 1000mm, with 300mm projected above ground level, shall be carried out for Master Control Points. Secondary Control Points shall also be established, with the provision of a 700mm-long M.S. angle (50 × 50 × 6mm), fitted with brass nailing for marking the Control Points. Additionally, the CP pillar number shall be engraved on an MS plate (125mm × 125mm × 5mm) embedded in concrete using four 6mm diameter rods of 150mm length, as per the attached drawing. Each pillar shall have the following reinforcement: 4 longitudinal bars of 10mm diameter 8mm diameter rings at 150mm c/c spacing The foundation size of the pillar shall be 800mm × 800mm × 150mm, with a PCC (Nominal mix 1:2:4) base. (Wherever feasible, marking should be done on an existing permanent structure. Otherwise, RCC pillars shall be erected with the permission of the Procurement Officer. Payment shall be made only for actual pillars erected at the site.) Refer to the attached drawing for further details. Payment Terms: 90% of the payment will be released upon completion of fieldwork and submission of data and reports. 10% of the payment will be released upon acceptance by the Railway.
