| 1 | Charges for drawal of ESP collecting plates of size 750 width x15 m long from central stores/ MTPS-II, loading into trailer lorry, transporting and unloading at ESP \"O\" mtr. level including transporting charges and hydro mechanical crane |
| 2 | Drawal of ESP spare materials such as Emitting Electrodes, Collecting and Emitting frames and all related internals from Central Stores / MTPS-II to ESP area. |
| 3 | Opening ofmanhole doors in 23 mtr & 13.5mtrelevation and closing all the manhole doors after dismantling, cutting and removal ofField and internals including hire charges T&P required, consumables and all labour charges etc., |
| 4 | Mechanical cleaning and water washingin ESPpass fields, including collecting plates, emitting electrodes rapping mechanism, structuresand closing all the manhole doors including consumables, lead, lift, T&P etc., |
| 5 | Removal of damaged / eroded/wornout ESP collecting electrodes (plates) of sizes of 750mm width X 15000 mm Long from ESP fields. The electrodes are to be disconnected from shock bars by cutting the shock bar bolts, nuts, scaffolding are to be erected at required elevation for lifting the 15 m long electrode to the top of the ESP roof. Derrick arrangements are to be erected with 4 Nos of collecting electrodes |
| 6 | Shifting of eroded / damaged ESP collecting electrodes from 30 mtr elevation to ESP ‘0’ mtr elevation and cutting it into 2 to 3 pieces and loading it to the vehicle and to central stores. |
| 7 | Cutting and removing the damaged ERM, CRM shafts, emitting Electrodes, CRM & ERM ladder & supporting structures, plain bearings , etc from ESP field as per direction of Engg in charge. |
| 8 | Shifting the eroded ESP shock bar guide plate & baffle plate from ESP 14 mtr to 0 mtr and loading it to vehicle, transporting and devolute at Central Stores/MTPS-II. |
| 9 | Removal of damaged collecting electrode supporting frames, lifting the ESP roof, shifting from 30mtr level to \"0\" mtr level. |
| 10 | Shifting of eroded / damaged ERM, CRM shafts, emitting Electrodes, ERM ladder, etc from to ESP ‘0’ mtr elevation and cutting it into 2 to 3 pieces and loading it to the vehicle and to central stores. |
| 11 | Removal of inner and outer casing longitudinal ESP roof plate by gas cutting or using welding electrodes, insulation wool mattress and Fixing, welding the same outer and inner casing longitudinal roof plate including cost of consumables and T & P and cost of welding electrodes and renewal or putting back the same insulation wool mattress after completion of work. |
| 12 | Erection of completed ESP field internals along with its accessories by transporting, lead, lifting (to the top of ESP roof at 25M elevation), fit-up leveling, inserting the 15M long collecting electrodeinto the ESP casing chamber oneby one with special tool & placing at the required place/ row and connectingthe bottom with shock bars by huck-bolt arrangements, tightening with special tools, erection of rapping mechanism, suspension & support frames for collecting & emitting electrodes, CRM & ERMmechanism, support insulators, insulation, alignment, completed welding of all supports, frames and modification of the BHEL make ESP internals such as collecting and emitting electrode supporting and suspension frame, ERM & CRM, ERM & CRM driving mechanism, Insulatorsetc., and as per direction of site Engineer all charges including cost of specialT &P \"s and consumables. |
