Digging out the old foundation block and then extracting out the base frame after cutting the nuts from foundation bolts using the electric cutter /gas cutter. Breaking the old RCC foundation block (4.5 x 2.5 x 3.5) ft with the help of chisel, concrete cutter, electric jack hammer and other tools / tackles. Cutting of steel members with the help of cutter step wise during the process of breaking the RCC block and stacking. Complete removal of broken concrete, soil and TMT bars from pump room in such way that the machinery and electric equipments of other pumping machinery are not damaged/ effected. Disposing of the excavated material to a distance not less than 100mtrs (approx.) from the pump room at such a place where irrigation land and water source is not polluted. Laying of new RCC foundation block of size 4 ft x3 ft x 4 ft approx. (as per size of the new base frame) by way of making surface even for laying of new RCC foundation block. Fabrication of steel mesh out of 10 mm steel bars placed vertically and horizontally at an equidistance of 6 inches duly welded on 40 mm MS angle outer frame. Laying of 6 inch concrete base at the bottom to level the surface. Placing of fabricated iron mesh in foundation pit and leveling / aligning it as per the new base frame. The job may include any other fabrication work required for proper fitting/alignment of pumping unit as per site conditions. The foundation bolts are to be welded to steel reinforcement of foundation block in proper alignment and spacing with respect to base frame properly leveled and sealed to the required position. Placing of base frame on newly constructed RCC foundation block and the already welded 06 No. foundation bolts of size 2.5 ft in foundation block. Laying of RCC foundation block of size 4 ft x 3 ft x 4 ft approx. (as per size of the base frame) by filling the concrete in the ratio of 1:1.5:3. The size of the block may vary slightly as per space availability and ground condition and should be in alignment with respect of suction and delivery pipes. The block shall be filled with rich mixture of concrete with using vibrator for compaction. The entire block as one unit is to be laid in such a way that it can damp all types of mechanical vibrations created by dynamic load of pumping unit without causing any defect to the pumping unit as well as to the block itself. Fixing of the base frame after levelling and fastening with foundation bolts.
