Amount

Providing, installation, testing & commissioning of electro-mechanical pumping machinery along with allied works at T/well Gujjar Basti Tarore under WSS Gujjar Basti Tarore on turnkey basis under Languishing Project. The complete job involves the following:

Submersible pump sets: Providing, installation, testing & commissioning of 02 nos. (01 working + 01 standby) 5000 GPH x 100 mtrs head submersible pump sets (submersible pump along with energy efficient 4/5 star rating 3-phase water lubricated wet type submersible motor) of nationally reputed make viz. KSB/ Calama/ Kirloskari only conforming to relevant IS codes with accessories at T/well Gujjar Basti Tarore.The job includes providing of new submersible pump & motor sets with thrust pad assemblies and coupling of the submersible pump with the motor. Fabrication of graded reducer fabricated out of G.I. pipe of requisite length and dia as per pump outlet dia, threaded at one end to hold delivery end of pump and welded at other end with heavy duty MS flange for pump’s fitting with flanged column pipe. 02 nos. nuts of size 16 mm are to be welded on opposite side of reducer so that clamping bolts of a tie-rod can pass through it. Coupling of the pump and motor assemblies. Fabrication of tie-rod clamping arrangement for clamping the pump & motor fabricated out of 40 x 6 mm MS flat with turn buckle arrangement made out of heavy duty 16 x 80 mm bolts welded at both the ends. The U-shaped clamp should pass though the bottom of the thrust pad of the motor and the bolts welded at its both ends should pass through the nuts welded on the opposite sides of the reducer for proper tying of the pumpset. Filling of the cooling jacket of motor with distilled water ensuring the system free of air bubble by making the water to circulate from inlet port through outlet port of motor followed by plugging of the same properly. Testing of the coupled pumpset by lowering the same in the test pit at workshop for checking the discharge of the pump and performance of the motor at zero head. Shifting of the pumpsets to site. Fabrication & fitting of MS well cap for covering of the top of tubewell with slots for passing of the delivery pipe & submersible cable along with modification of delivery line and also 2-1/2' x 2-1/2' top cover for the roof opening as per site requirement. Providing of new 6 sqmm submersible copper cable of reputed make KSB/L&T/Havells/Polycab only in place of old worn out submersible cable, 90 mtrs. in length, making of connenction of submersible motor with submersible cable with high grade patch roll & insulation tape and then lowering of the new submersible pumpset along with the column pipes one by one in the tube well after providing & fitting of nuts, bolts and rubber insertion sheets etc. The complete job includes cost of the submersible pumpsets, G.I. pipes, submersible cable, providing, fabrication/fitting charges of GI pipes with flanges/ nipple with flange & MS U-clamp, nuts/bolts, patching roll, rubber gaskets, lowering charges, all labour, carriage charges and taxes etc. Complete job including testing of submersible pumpset after making all electrical connections of the submersible motor with the LT control panel at site.

Installation of voltage stabilizer: Installation, testing & commissioning of 63 KVA voltage stabilizer (to be provided by the Department) by shifting of the stabilizer from Divisional store Vijaypur to site on mechanical transport, unloading it by crane, dragging it inside of the pump room by crane / manual labour. Shifting it to appropriate place. Check for any moisture inside the oil tank by opening of the drain valve, checking of the MCCB, changeover switch etc. and then rectification of any fault, if any, identified before installation of the stabilizer at site. Filling of the transformer oil approx. 200 litres (provided by the Department). Make inter-connection of the LT cable from electric transformer to voltage stabiklizer & then from voltage stabilizer to main switch on the panel board by providing of heavy duty thimbles & proper crimping of the thimbles to the LT cable with crimping tool at each end. Complete job in all respects including testing of stabilizer first on no load & then on full load at site.

Testing & Commissioning: Testing and commissioning of submersible pump sets, voltage stabilizer and fully automatic LT control panel along with all electro-mechanical system on load at site by checking of electrical system by identifying any loose electrical connections, their re-taping thereof and proper operation of the star-delta starter. Complete job in all respects as per site conditions.

Painting: The job also includes proper painting on the wall with black & white enamel paint mentioning clearly the particulars of the machinery / equipment installed under Languishing project at theT/well station.

Note: The intending tenderer should visit the site before quoting to fully acquaint himself with the site location, nature and quantum of job. The job shall be undertaken after completion of pump room building.
