Introduction:
National High-Speed Rail Corporation Limited (NHSRCL) (the “Employer”) was incorporated on 12th February 2016 under the Companies Act, 2013 with an object to finance, construct, maintain and manage the High Speed Rail Corridor in India. The Company has been modelled as ‘Special Purpose Vehicle’ in the joint sector with equity participation by the Central Government through the Ministry of Railways and two State Governments viz. Government of Gujarat and Government of Maharashtra.
- The Company would be ushering India into the category of few countries of the world (about 15) using the High Speed Railway System. The High-Speed Rail (HSR) project apart from being a technological marvel, would afford many quantifiable benefits like saving in travel time, vehicle operation cost, reduction in pollution, job creation, reduction in accidents/ enhanced safety, imported fuel substitution, and reduction in pollutants. The project would also boost the infrastructure and add to the growth of the economy.
- HSR would be an integrated system having overall optimization of various components, viz. Hardware, Software, Human-ware, and their interface, etc. National High-Speed Rail Corporation Limited (NHSRCL) is in the process of preparation of Detailed Project Report for new High speed rail corridor from Varanasi-Patna-Howrah. The length of this corridor is approximately 787 km.
Scope of Work :
The complete scope of work for this tender is divided into two parts:
Survey & identification of overhead, over ground and underground utilities along the proposed route of Varanasi-Patna-Howrah High Speed Rail (VHHSR) Corridor.
Brief Details:
The proposed Varanasi-Patna-Howrah (VHHSR) High Speed Rail Corridor is planned along major expressways/ national highways, greenfield areas and may be passing through arterial roads of the intermediate city road network for High Speed Rail connectivity between different cities along the corridor. Large number of overhead, surface and sub-surface utility services viz. electrical transmission lines, electric distribution lines/poles, traffic signals, telephone cables, sewers, water mains, storm water drains, gas/oil pipelines etc. are anticipated to be existing along the proposed alignment. The utility services may have to be planned for shilling, modification to enable construction of HSR structures and/or to ensure safety & adequate clearance as per HSR requirements.
As such, these utilities may critically affect the construction works and project implementation time schedule and costs, for which necessary planning / action needs to be initiated in advance. In view of above intent, the contractor/agency shall plan, execute and perform following activities, as a minimum:
- Survey, identification of infringing:
- electrical lines of different voltage class namely LT, HT, EHT etc. belonging to Central/State Govt. authorities or their undertakings, Private entities, including electrical connections for bore well/ tube well for agriculture purpose or otherwise.
- Railway OHE installations.
- Telecom Towers/Lines, Telephone Poles, S&T Installations etc. This survey would be both for above such utilities on the ground or above ground; either crossing or miming parallel to the proposed corridor width defined in following paras.
- Utility services on the Ground or above Ground: The details of existing utility services on the ground or above ground shall be picked up through total station/DGPS and visual inspections. All identified utilities shall be surveyed for accuracy by DGPS/DGPS control points to be fixed by the agency. All identified utilities shall be marked on proper UTM co-ordinates.
- Following details would be collected and included in the report for identified electrical lines/crossing(s) & other identified utility services in the relevant format as per Format-I attached along with TOR & also good quality photographs of identified infringing utility services properly indexed (along with soft copies). Details would include voltage class, ground clearance, span length, coordinates of tower/pole at entry & exit of HSR RoW, crossing (feeder/line) particulars, village/tehsilIdistrict in which the electrical line/crossing falls, Utility owner particulars amongst others.
- Underground utility services: Includes electrical/power cables, OFC, Sewerage, Pipelines (Water, Gas, Petroleum etc.) & other utility services amongst others. All identified utilities shall be surveyed for accuracy by DGPS/DGPS control points to be fixed by the agency. All identified utilities shall be marked on proper UTM co-ordinates.
- Entire Route & other selected stations, Depots, OCC locations: Detailed drawings of existing underground utility services for the entire route & other selected stations, Depots, OCC locations shall be collected from the concerned departments/various stakeholders and the same shall be identified/ picked up by total station/DGPS at site through tell-tale signs and verified with drawings collected from concerned departments/organization.
- For entire route & selected locations for underground utilities: Following details would be collected and included in the report for identified underground utility services in the relevant format as per Format-2 attached along with TOR & also good quality photographs of identified infringing utility services properly indexed (along with soft copies). Details inter alia would include type of utility, depth, material, co-ordinates at entry & exit of HSR ROW, crossing particulars, village/tehsil/district in which the crossing falls. Utility owner particulars amongst others.
- The existing utility services shall be identified within the proposed Right of Way/Land boundary. The route length, width of right of way and area of stations, sub-stations and other infrastructure planned for the corridor is provided with this tender. Further details of proposed alignment shall be provided by NHSRCL to the successful bidder at the time of contract agreement. The details is defined as follows:
- Tentative route length is approximately 450 km. Tentative Route is attached at as per attached in Vol-5 (Tender Drawing).
- Width of ROW for the main line mute (expect stations, Depot, OCC etc.) would be approximately 30 meters (15 meters from the center line on each side)
- Dimensions of Station (as mentioned at Clause 1 above) are as follows:
- Length=2000 meters (1000 meters from mid-point on both directions)
- Width= 200 meters (100 meters from center line on both sides)
- Dimensions of Depots & OCC are as follows:
- Length=2384 meters
- Width= 725 meters 2.2.4
- The agency is required to establish its own ground control control points for the purpose of survey of identified Utilities Services on the corridor. The agency will superimpose the coordinates of Utilities services surveyed/identified on corridor, with respect to Ground Control Points (GCP) established later at site by other Contractor of Employer, in case they are made available before the completion of contract. The agency to submit the final report after making good the shortcomings if any in comparison with GCPs of other contractor. The permissible limit of error of closure is 1 in 50,000 in horizontal control & 124K mm (where K is circuit length in Jon) for vertical control.
- Identification of Power Sourcing options (suitable Grid Substations, shortest optimal Transmission line/HV cable route & length) for Traction Substations (TSS) & Distributions Substations (DSS) along the proposed route of Varanasi-Patna-Howrah High Speed Rail (VHHSR) Corridor by interaction with power utility companies & through preliminary survey.
