Building

  1. Floor 1 is the lowest floor above the ground level in the building unless otherwise specified in a
    particular case. The floors above floor 1 shall be numbered in sequence as floor 2, floor 3 and so on. The number shall increase upwards.
  2. Floor level: For floor 1, top level of finished floor shall be the floor level and for all other floors above floor 1, top level of the structural slabs shall be the floor level.
  3. Plinth level: Floor 1 level or 1.2 m above the ground level whichever is lower shall be the plinth level.

Special Structures

  1. For structures like retaining walls, wing walls, chimneys, over head reservoirs/ tanks and other elevated structures, where elevations/ heights above a defined datum level have not been specified and identification of floors cannot be done as in case of building. Level, at 1.2 m above the ground level shall be the floor 1 level as well as plinth level. Level at a height of 3.5 m above floor 1 level will be reckoned as floor 2 level and level at a height of 3.5 m above the floor 2 level will be floor 3 level and so on, where the total height above floor 1 level is not a whole number multiple of 3.5 metre. Top most floor level shall be the next in sequence to the floor level below even if the difference in height between the two upper most floor levels is less than 3.5 metres

FOUNDATION AND PLINTH

The work in foundation and plinth shall include:

  1. For buildings: All works upto 1.2 metre above ground level or upto floor 1 level whichever is lower:
  2. For abutments, piers and well steining: all works upto 1.2 m above the bed level:

  4. For reservoirs/ tanks (other than overhead reservoirs/ tanks): All works upto 1.2 metre above the ground level:
  5. For basements: All works upto 1.2 m above ground level or upto floor 1 level whichever is lower.

Note: Specific provision shall be made in the estimate for such situations where the foundation level is more than 3 (three) metre depth from the plinth for all types of structures mentioned above.

MEASUREMENTS

  1. In booking dimensions, the order shall be consistent and in the sequence of length, width and height or depth or thickness.
  2. Rounding off: Rounding off where required shall be done in accordance with IS: 2 1960. The number of significant places rounded in the rounded off value should be as specified.
