Boring/ drilling bore well of required dia for casing/strainer pipe, by suitable method prescribed in IS: 2800 (part-1), including collecting samples from different strata preparing and submitting strata chart/bore log, including hire and running charges of all equipment tools plants and machineries required for the job, all complete as per direction of Engineer-in-charge beyond 90 m & up-to 150 m depth below ground. (The drilling depth may increase or decrease at the time of execution subject to physical conditions). All kinds of soil (Diameter of casing/strainer pipe = 250 mm)

Gravel packing in tube well construction in accordance with IS 4097, including providing gravel fine/medium/coarse in required grading and sizes as per actual requirement all complete as per direction of Engineer in-charge.

Supplying, assembling lowering and fixing in vertical position in bore well, ERW (Electric Resistance Welded) FE 410 plain ended casing pipes of required dia, conforming to IS: 4270 of reputed and approved make, including painted with outside surface with two coats, of anticorrosive paint of approved brand and manufacture including required hire & labour charges fitting and accessories, all complete for all depth, as per direction of Engineer-in charge. 250 mm nominal dia The Length of casing pipe may increase or decrease at the time of execution work as per the approved casing diagram

Supplying assembling, lowering and fixing in vertical position in bore well ERW (Electric Resistance Welded) FE 410 plain slotted (having lot of size 1.6/3.2 mm) plain bevel ended pipes (type A) of required dia conforming to IS:8110, of reputed & approved make including painted with outside surface with two coats, of anticorrosive bitumestic paint of approved brand and manufacture including required hire labour charges, fitting and accessories, all complete for all depths, as per direction of engineer-in-charge. 250 mm nominal size dia. The Length of casing pipe may increase or decrease at the time of execution work as per the approved casing diagram

Development to tube well in accordance with IS: 2800 (Part I) and IS: 11189 to establish maximum rate of Potable water yield without sand content (beyond permissible limit) with required capacity air compressor running the compressor for required time till well is fully developed measuring yield of well by “V” notch method or any other approved suitable method measuring static level & draw down etc. by step draw down method collecting water samples and getting tested in approved laboratory, i/c disinfection of tube well all complete including required hire and labour charges of air compressor tools & accessories, etc all as per direction of Engineer-in-charge. The grouting & sealing of the tube well has to be done to ensure safe sanitary conditions. The well casing shall be anchord with ISMC-150 & CC block. The CC block shall be laid of size (2x2x1) Mtr in M-15 mix excluding the annular dia of the well and slopping away from it to prevent contaminated water flowing back into it. The casing pipe has to be anchord by welding ISMC-150 steel bracing of 2.00 mtr length each (04 No. bracing or channels) with cleats and sufficent welding area, bracing embedded with the cement concrete block as per the directions of the site engineer. The complete well after yield test and till desired results of water with maximum tolerance of permmisble turbid free water, thus completed and handedover to the territorial mechanical division for harnessing .
