Construction of Coffer dam with base width 4.00 mtrs, top width 3.00 mtrs & 3 m height above ground level in the nallah side of the structure to prevent water from entering the site with suitable materials like jungle ballies drum sheets etc on both side and filling non pervious soil in between with proper compaction. The coffer dam should have strength to withstand the water pressure during flood including bailing out water continously during construction if structure including dismantling the coffer dam fter completion of work.

Extra for laying reinforced cement concrete in or under water and/ or liquid mud, including cost of pumping or bailing out water and removing slush etc., complete. cum 794.65 Note For Item No. 5.31:- The quantity will be calculated by multiplying the depth measured from the subsoil water level up to the centre of gravity of the R.C.C. under subsoil water with the quantity of R.C.C. in cubic metre executed under subsoil water. The depth of centre of gravity shall be reckoned correct to 0.1 m. 0.05 m or more shall be taken as 0.1 m and less than 0.05 m ignored. No extra payment shall be made for placing reinforcement or centering & shuttering under sub - soil water conditions.

Extra rates for quantities of works, executed: Note for item no. 2.24:- The extra percentage rate is applicable in respect of each item but limited to quantities of work executed in these difficult conditions. The unit, namely, metre depth, to be considered for payment, shall be the depth measured from the sub soil water level up to the centre of gravity of the qty executed in difficult conditions. The depth shall be reckoned correct to 0.10 m, 0.05 m or more shall be taken as 0.10 m and less than 0.05 m ignored.
