Supervisor and safety officer shall monitor the lifting work. 9. Application of Lean Concrete Before pouring of lean concrete surveyor should confirm the levels of excavation area and make marking of lean concrete level as per the approved drawing. FDT result should be equal or above 95% of proctor value to start concreting work. The form-work of 100mm thickness for blinding will be fixed, alignment and leveling should be done properly prior to start pouring concrete. Lean concrete will Casted at the joint of cable area wide of 2700mm x 8000mm in a length.

A two layers of polyethylene sheet of 150 micron will install on the compacted blinding area by using the approved material. Sketch drawing will submit to NG showing the casting area,pump location and access of the concrete trucks and check point. Safety precaution shall be taken into consideration starting from the site entrance including the pump and trucks access till casting area. Proper light will be available when concrete pouring continues till night. The concrete trucks will be unloaded at work site within 90 minutes of batch loading time of concrete. Casted blinding will be cured properly with covering hessian clothes before start installation of hessian clothes it should be wet. The concrete will be cure for two to three times in day for a period of seven days. The surface preparation will fallows to make surface of concrete smooth,crack free and reduce undulation of the surface with approved material prior to start waterproofing work After the surface preparation of the lean concrete raise the inspection to NG prior to start waterproofing. 10.
