RVNL shall make payment for such work.
Track Laying & Linking:
- 60 Kg/90UTS rails on PSC sleepers with density of 1660 sleepers per km with 350 mm ballast cushion shall be provided for the main line. In station yards, for the loop lines, 52 Kg rails on PSC sleepers with a density of 1660 sleepers/Km with 350 mm ballast cushion have been proposed. The main line is proposed to be provided with LWR / CWR. Loop lines shall be provided with SWP/ LWR.
- Yards will be tracked. Glued joints shall be provided wherever required. 60 Kg points and crossings on PSC fan shaped layouts have been proposed.
- Hard Stone ballast of 65 mm size with 350 mm cushion on the main line and the turnouts and 350 mm cushion on loops and sidings shall be provided.
- The work also involves slewing / regrading of existing tracks and relaying / dismantling of Pway and Points & crossings, wherever necessary.
- After the formation is ready and cleared by the Engineer for track linking the rails (Single Rails/3 Rail Panels) shall be unloaded on the formation.
- Flash butt welding shall be done to convert the single rails into LWR/CWR as per plan approved by RVNL by the contractor’s portable road trailer mounted flash butt welding machine. If there is delay in formation being ready, single rails can be converted into 3/4 Rail Panels in depots and then these 3/4 Rail Panels can be converted into LWR/CWR after transferring them to formation.
- PSC sleepers shall be transported by road and stacked near level crossings.
- The required quantity of ballast to the maximum extent (not less than 2 Cum per meter length) shall be brought by contractor’s dumpers on the formation and spread on the proposed alignment by contractor’s grader. The grader should spread and level the ballast in a width of 3.2 meter (Bottom) and cushion of 200 mm.
- The remaining quantity of ballast shall remain on the common cess of existing/proposed track, leaving clear space for linking of auxiliary track.
- After laying of ballast is completed in a particular stretch between level crossings then auxiliary track shall be laid at a gauge of 3400 mm with centre line matching the proposed track.
- Now the sleepers shall be lifted from the stacks near the level crossings with the help of hydra and kept on the formation between auxiliary track for being picked up by portals for leading them to point of laying in case portals are proposed to be used for transport and laying of sleepers.
- Contractor shall bring his own mechanised portal equipment which will be capable of traveling on the auxiliary track and will transport the sleepers from L-Xing to the location of linking.
- At the location of laying, the sleepers shall be laid at the required spacing ensuring that the centre line of sleepers matches with the centre line of proposed track. Instead of portals, sleeper laying equipment which does not require use of auxiliary track, can also be used for laying of sleepers.
- After the sleepers are laid on the ballast bed of 200 mm thickness, contractor shall arrange his own Rail Threader to pick up the auxiliary track rails from both sides and lay on the PSC sleeper at Rail Seat to complete the laying of track.
- The ballast lying along the track shall be put in the track in the cribs and shoulders for taking up the work of lifting the track to provide a required cushion of 350 mm.
- Track shall be lifted and aligned by small track machines. The lifting and aligning machine should be light in weight and should be transportable by road from one site to another. This lifting, aligning and tamping may be required in 2-3 phases until the desired clear cushion and proper alignment is achieved.
- Behind the lifting aligning machine, a contractor’s small track machine capable of tamping to be deployed. The Tamping machine should have 8 Nos. of tamping tools so that one sleeper can be tamped completely per insertion. This light duty tamper should be self propelled and should be transportable by road from one place to another.
- The contractor shall unload additional ballast over the track by his own mechanized means or manually as per site conditions and directions of Engineer to achieve desired ballast profile.
- For achieving the desired cushion and to fill the inter-space of sleepers as well as crib ballast as per final profile, whatever ballast will be required in phases to be unloaded by the contractor with his own equipment and machinery.
- The contractor, after a sequence of linking, lifting, aligning and packing with his own tools, plants and equipment shall bring the track parameters in floating condition within the tolerance limits as specified in IRPWM.
- The track thus laid shall have speed potential of 45 kmph. After this Railway’s heavy ontrack tampers shall be made available for machine packing to achieve normal sectional speed.
- Two packings shall be done by the contractor with Railway’s heavy ontrack tampers. After the first tamping the track shall be made suitable for speed potential of 75 kmph. The second tamping (final tamping) shall be done in design mode and the track shall be made suitable for maximum permissible sectional speed.
- Profiling of ballast shall be done to achieve the ballast section as prescribed in IRPWM.
Civil Work:
- While planning for the work of transportation of bridge construction materials to the bridge site., the finished formation of earth work in banks and cuttings with or without blanket layer should not be used for plying of trucks or other vehicles used for transportation.
- This restriction has specially been imposed to save the top surface of the formed formation from forming pits and ruts, which later are likely to accumulate water and pose problems for maintenance.
- The mechanical means required to meet the stipulations mentioned in the above sub Para should be arranged by the Contractor.
- Railway land, if available and spareable, shall be provided for the purpose of stacking of material and setting up of concrete batching plant, etc. However, the Contractor shall be responsible for arranging any such requirement of land and arranging/developing any required approach to site of work, etc at his own cost.
