STANDARD WASTAGE CONSIDERATION FOR BUILDING MATERIALS

A Vision To Clear Solutions.


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 %
