BHUBANESWAR: Odisha Rail Infrastructure Development Ltd (ORIDL) had floated two separate tenders for appointing the General Consultant (GC) for conducting the Aerial LiDAR Survey, preparation of Feasibility Study, Alignment Design, Detailed Project Report (DPR), Cost estimation and preparation of Land Plans and documents for land acquisition in connection with construction of new electrified BG Rail line for the 275 km Jagannathpur-Rairakhol and 78 km Rajathagarh-Kaipadar Road sections in the state of Odisha falling in the jurisdiction of East Coast Railway. ORIDL will be the employer and the consultancy firm will be providing services to ORIDL. The standards of output required from the appointed agency/firm are to be of the highest standards both in terms of quality and adherence to the agreed time schedule.
Reconnaissance Engineering and Traffic (RET) Survey for the project has already been conducted by East Coast Railway in the year 2013 with route length of 81.7 Km. ECoR has prepared a revised RET Survey report in the year 2018 changing the alignment to connect Kaipadar Road with Naraj Marthapur station instead of Rajathgarh station with a route length of 68.5 Km. The proposed alignments and location of stations have been indicated in the RET Survey reports. The consultant is required to examine both the RET survey reports and is expected to optimise the alignment and designs for achieving better economy in cost as well as time of construction.
The purpose of this GC consultancy is to study and start from what has already been reported in earlier reports of East Coast Railway as described, verify them including through fresh survey including fresh detailed topography survey using Aerial LiDAR Technology (with the help of helicopters/aircraft), collect the hydrological data and design the waterway of bridges, design the alignment and formation levels, carryout Final Location Survey, prepare GADs and Engineering Drawings for a new Railway corridor taking off from Rajathgarh/Naraj Marthapur station on Barang – Talcher route and joining at Kaipadar Road station on Howrah – Chennai route of East Coast Railway (AND) Jagannathpur station on Howrah – Chennai route and joining at Rairakhol station on Angul – Sambalpur route of East Coast Railway.
The GC is required to finalize the exact and optimum route length and track length under the scope of this contract and to conduct desk study of earlier survey reports, railway alignments, data, drawings and plotting the earlier alignments including suitable and alternate connections with at either end in consultation with ORIDL and ECoR on Google Earth/KMZ format and broadly checking whether the route selected earlier is the best one and prepare other possible alternatives for decision. It is also the responsibility of GC to study the proposed serving stations, identification of locations for bridges, cross-drainage structures, level crossings / ROB / RUB and marking of high tension/low tension wire and any road crossing etc. Aerial LiDAR survey (using Helicopter/aircraft) with horizontal & vertical ground control network along the proposed / possible alignments to establish X, Y, Z co-ordinates along alignment and taking coordinates of stations, yards etc., as may be required for the purpose of setting out and construction of the proposed railway corridor and to design the alignment with a Ruling Gradient of 1 in 100 (compensated).
Apart from various high level scope of works and services, the GC shall also be liable to execute the Scanning, Digitization, Geo-referencing (w.r.t WGS-84 co-ordinate system) of Survey of India (SOI) topo maps/Geological maps/forest maps/revenue maps etc. and their use in design of the alignment for identification of environmentally/geologically sensitive areas and for preparation of land acquisition/forest clearances plans as per direction of Engineer. The Consultant shall procure, collect and use the relevant maps from the concerned agencies.
Along with the tender, the tenderer is required to submit a broad methodology of execution of works to fulfil the scope of work.
