STANDARD WASTAGE CONSIDERATION FOR BUILDING MATERIALS:

STEEL MATERIALS:

·                     Allowable wastage for steel works is 3 %( i.e. cutting/bending wastage).

·                     For reconciliation purpose, + or -2% allowable for rolling margin in this accounts.

·                     Above 25 mm dia of rods 5% wastage should be considered.

CONCRETE MATERIALS:

·                     Concrete pouring or placing time & during loading, transportation lot of concrete it will be waste.So normally concrete wastage 3% considered.  

TILES MATERIALS:

·                     Tiles loading,transportation and placing time lot of broken and cutting it will be happened.

·                     Tiles wastage normally 5% Considered.

PAINT MATERIALS:

·                     Paints applying at the time some paints it will fall on the ground.so during time wastage it will be happen.

·                     Paints wastage normally 2% Considered.

GRANITE MATERIALS:

·                     Granite materials loading,transportation and placing time lot of broken and cutting it will be happened.

·                     Granite wastage normally 5% to 8% will be Considered.

BRICKS MATERIALS:

·                     Bricks materials loading,transportation and placing time lot of broken and cutting it will be happened.

·                     Bricks wastage normally 5% will be Considered.

CEMENT MATERIALS:

·                     Cement materials loading,transportation ,mixing ,shifting & placing time  lot of wastage it will be happened.

·                     Cement materials wastage normally 1.5%  to 2% will be Considered.

COARSE AGGREGATE MATERIALS:

·                     Coarse aggregate materials loading,transportation and placing time lot of wastage it will be happened.

·                     Coarse aggregate materials wastage normally 5% will be Considered,

FINE AGGREGATE MATERIALS:

·                     Fine aggregate materials loading,transportation and placing time lot of wastage it will be happened.

·                     Fine aggregate materials wastage normally 10% will be Considered

STRUCTURAL STEEL MATERIALS:

·                     Structural steel materials fabrication time  lot of cutting and wastage it will be happened.

·                     Structural steel materials wastage normally 5 to 10% will be Considered

As Per Study  done at different Locations Considering different atmospheric conditions,the average wastage of materials are.

·                     Cement = 1.3%

·                     Reinforcement Steel =3.35%

·                     Brick =4.42%

·                     Course Aggregate = 4.49%

·                     Sand = 3.56 %
