Removing of both Bar Screen which is hold on electric hoist at the height of approximate 4 metre from the ground level will be taken out by hydra to clear the site for making workable space from to put on safer side near the bar screen chamber.

Breaking of work which need fixing of grouting of main I-Section beam of size 300x140 on both side of running Raw Water Channel by manual labour / concrete breaker etc. as required by job on both side of boundary wall.

Removing of complete structure of guide Bar Screen Channel by cutting of all part with wall & I-Section beam etc. which control the guide of bar screen from the under Bar Screen with the help of hydra etc. as required.

Cost of M.S Platform (03 Nos.) for fixing of M.S Triangular frame with I-Beam of size 300x100, length 5 Mtr.- 6 Nos. with M.S I-Beam of size 200x100, length 1.25 mtr. duly welded on incoming RCC Channel by taking proper safety precaution / measurement for support of chequered plate of size 5 Mtr. x 1.25 Mtr. x 8mm thick on M.S Frame duly welded etc.

Making of M.S Frame triangular structure made from the U Channel of size 300x90mm in triangle shape by 4 meter height with distance of 1 mtr., 4.5 Mtr. Taper, 3 Mtr. in horizontal position and 4.2 Mtr. in cross support for U Channel and 4.2 Mtr. width to make a complete structure for fixing of U Channel to support as guide of manual bar screen in flow of water in channel as per designed for Bar Screen fixing arrangements.

Railing arrangement for platform as per site requirement.

This complete structure fabricated as per triangular shape with proper support is to be fixed in under water structure with proper alignments. There is putting support of hydra outside the channel to pull in against the flow & one end against I-Section Beam & also making alignment with U channel in such way that this structure is to be welded in existing I-section beam of size 300 x 140. This process will be continuous upto complete structure fixed in all respect with in almost 8 points as required by the job. This continuous work will be doing in 2 to 3 days time as it is with holding of structure in straight position. After complete fixing of triangular structure frame in the under water by welding of complete structure in all respects with proper support so that the guide at channel of bar screen should not be disturbed during the operation & the operation of bar screen should not be disturbed during the operation process continuous.

Painting of platform and both bar screen by manual labour & repainting both bar screen & other structure is required by job. After complete fixing of structure these both bar screen is put in the guide by hydra in other position one by one. Also operating on system in this operating level.

The bar screen which is lying outside of system lifting by hydra to outside that is to be repaired by welding & if any structure damage will be replaced by cutting of damage structure & welding in respect to movement free up & down ward.

The both side of bar screen which is lying outside duly repaired is to be fixed in U guide with the help of hydra in the proper guide with proper alignments etc. as required & making proper operation by electric hoist which is fixed in I-section beam in these alignments.

Complete civil work as required by site. This includes all brick & CC work.

Testing & commissioning charges of complete job.
