The panel should be sturdy enough for vibration free operation and should be equipped with suitable locking /sealing arrangements. The structure should be provided suitable entry and exit holes for incoming and outgoing cables. The panel should be given two coats of anti rust primer and two coats of steel grey enamel paint. The panel should have equipped with following components / features: M.C.C.B.The panel should be fitted with an M.C.C.B. of 400 Ampere capacity, 1 no. volt meter, 1 no ammeter along with a set of CTs, 1 No. V.S.S., 1 No. A.S.S. and a set of RYB indicators at incoming side. 1. Star delta Starter:.The panel should be fitted with a fully automatic star delta starter comprises of 3 Nos. air break contactor of suitable capacity (2no 250amp for main and delta supply, 1 No.185 amp air break contactor for star operation), 1 No. timer for change over the supply of motor from star to delta, 2 Nos. push buttons for start and stop operation of motor, 1 No. indicator .1 No. MCB for the protection of internal control wiring, a neat and clean internal control wiring should be made with flexible copper cables to complete the star delta circuit of out going supplyfor pumping unit no. 1. 2.Protections device / fault analyzer: A protections devise / fault analyzer shall be fitted with the panel with capability to protect the motor by isolating the power supply of motor by de-energizing the starter/panel from following electro-mechanical faults which may otherwise damage the motor windings : A. Voltage related fault: Single phasing, under voltage, over voltage, unbalance voltage. B. Current related fault: Over current / load, dry running, unbalance current / load, earth leakage, short circuiting. C. Mechanical fault: Locked rotor, broken shaft, a. Display line current of RYB Phase and also line voltage of RY and YB phase. b. Display and indicate trip status for over load, under load, single phase, unbalance, earth fault, over voltage, under voltage respectively. 2. Bimetal overload relay: A bimetal over load relay of suitable range should be fitted with in the starter as an extra protection to protect the motor in case of failure of fault analyzer with an isolation/bye pass switch to bye pass the fault analyzer. 3. Cable-: Providing/ fitting of single core copper cable120 mm2 of 30 m (approx) in length from starter to motor. Complete job includes cost of providing/ fitting ,transportation charges ,hire charges, tool and tackles charges, hire charges of skilled and unskilled labour, To and Fro transportation charges at site of L.I.S and all kinds of taxes thereof. (B)Design, fabrication and erection of G.I/M.S shed at Lift Irrigation Scheme Dheri dhara.

The job involves bush cutting, removing of stones, pebbles etc. to enable the open surface for shed area and throwing away the same at a certain distance at a suitable place. Excavation job by digging/ laying and filling of (10’ x 1.5’ x 10’) plinth with 1:1.5:3 cement concrete mix at three sides. The job includes the erection of 4Nos. M.S channels (ISMC 100mm), 12’ long including embedding 3’ deep in the plinth at centers on opposite sides with 1sq. feet M.S plate to be welded at its bottom with properly grouting. Creating of in build super structure by way of welding 4No.s Angle iron (AA 40x40x6mm) 12’long at the top roof end to end. Also welding of 9No M.S .angle iron members, 12’long vertically and 12No. M.S angle cross members, 10’ long horizontally for all the three sides with the intermediate angle iron members. The job also includes providing and installation of 1No. M.S Bar (ISMB 150 mm) 10’ long on top at center of the shed. The job includes welding of appropriate no. of angle iron (AA 40x40x6mm) length with appropriate spacing at the top during the period of in build structure of roof for laying and fixing of GI sheets with nuts/ bolts, fastening. .Providing and fitting of 05No.s G.I sheets of 12’x2.75’ and 12 No.s G.I sheets of 10’x2.75’ with steel hooks on the super structure created for roof and sides.. Complete job includes the cost of material, carriage charges, hire charges of tools, tackles and labour charges for skilled/semiskilled labour deployed at site. The job also includes the charges for electrification of the shed at the site of LIS Dheri dhara. (C)Providing/laying of 250 mm dia. M.S Pipe measuring 18mtrs in total length to be utilized during laying and fabrication of wash out arrangement for the existing Rising Main of LIS Dheri dhara by way of cutting and welding to existing Rising Main 250mm dia M.S Pipe for installation of wash out system after connecting/ laying of new M.S pipe by way of welding with good quality M.S Electrodes for slag free welded joints with chipping and use of grinder to suitable surface finish. The job further includes fabrication of suitable M.S bends as per site conditions from the existing new M.S pipe of 250mm dia of 1.5 meter average length with a wider curve including its fitting with complete circumferentially welding job to be done at site to avoid all gaps .
