Railway Works & Supplies Tenders

Dismantling of existing structures like culverts, bridges, retaining walls and other sturcture comprising of masonry, cement concrete wood work, steel work, including TandP and scaffolding wherever necessary, sorting the dismantled material, disposal of unserviceable materials and stacking the serviceable materials with all lifts and lead of 1000m as per Technical Specification Clause 202

Excavation in foundations by mechanical means in all types of soils, boulders, WBM roads, including rock not requiring blasting including dewatering by manual or mechanical means etc. as per specifications with all contractor’s own machinery and equipment, crossing of track, shoring, strutting, timbering and buttressing with sand /clay bags and all such measures necessary to retain in position the sides of the foundation pit and including backfilling, rolling the excavated material with watering, ramming, levelling the site and disposing off the surplus/unusable earth to low lying area within railway boundary with all leads & lifts as per directions of Engineer. Note:- 1. The rates are inclusive of all safety measures to be adopted for protection of structures in the vicinity of works. 2. Payment shall be made only for design profile and no payment shall be given for any over cut. 3. The excavation shall be done by any mechanical means to suite site conditions etc. 4. Disposing off the surplus/unusable earth to outside railway boundary with all leads & lifts as per directions of Engineer will be paid separately under relevant item.

Running track site:- Replacement of old sleepers ( TSR) by dismantling existing track of all types of sleepers by making 13m loose rail panel (or any suitable length panel) with old sleepers & SH rail (for removing existing track) with wider base sleepers / revised wider base sleepers at density of 1660 sleepers per Km assembled with loose rail panel (or any suitable rail length panel of SH rail)in PQRS Depot and placing over ballast properly during traffic block after removing panels of old sleeper and SH rail of 13 m loose rail panel (or any suitable length panel) with the use of contractor's PQRS Machine by providing auxiliary track with gauge of 3400mm (either with the use of existing rail from existing track or with new rail over metal/ wooden sleepers, to be provided by Railway, 500 Nos./rail km on both rails) and providing fish plates for joining loose SH rail over wider base sleepers / revised wider base sleepers for continuity of track and maintaining track parameters as per Para 522 of IRPWM 2020 to keep the track fit for 30kmph. SH rail over new wider base sleepers / revised wider base sleepers to be replaced with new/earlier existing rail on running track (with replacement of rubber pad, liner & greased ERC and greasing of liner contract area. Grease to be used should be of Servogem RR3 from Indian oil) as soon as loose rail length of track reaches 500m/750m (as per decision of Railway site engineer i.e. SSE/JE/ P Way). Loading of track 1 panel( SH rail over old normal sleeper and tied with ERC) of approximately 13 m length over Railway wagons and unloading of track panels of the length of 13 m ( or any suitable length) and wider base sleeper / revised wider base sleeper will be done during traffic block. TRR with the rail of the length of 250 m to 500m which was removed initially for AT, will have to be done as soon as track of loose rail exceeds 500m length. The whole process will continue till completion of work. Auxiliary Track (AT) will have to be removed with advancement of TSR work as per direction of Railway (SSE/JE/P Way). b) PQRS Depot: - Track panel with SH rail of 13 m or any suitable length over wider base sleepers / revised wider base sleepers will be made with necessary fittings in PQRS Depot. Loading of these panels over Railway Wagons and unloading of released track panels (released from running track) consisting of all types of rails & sleepers from Railway wagon at PQRS depot using Contractor's own portal crane including dismantling and stacking each component of track properly at designated locations. Note: This item of Through sleeper renewal with wider base sleeper / revised wider base sleeper is a composite item and all activities as required will have to be done by the Contractor with his/her own PQRS Machine & other machines, tools and plants including all other resources as per requirement of the work ( in PQRS Depot and during traffic block in running track). Railway will provide wagons and locomotive free of cost for loading/unloading and transportation to/from PQRS Depot/ work site (running track) for loose rail panels with normal old sleepers and with wider base sleepers / revised wider base sleepers. Nothing extra will be paid except the rate as mentioned against the item. Railway will also provide metal/wooden sleepers required for AT, free of cost. Various activities which are involved in TSR work are elaborated in "sequence of activities provided with tender schedule". (For Final product and Notes refer Annexure-A).
