ESTIMATION OF STAIRCASE | QUANTITY OF BARS FOR 20 STEPS | COST OF STEEL BARS

General Guidelines for Design of Staircase Calculation:
The following are some pointers to be considered while planning a staircase:
• The respective dimensions of tread and riser for all the parallel steps should be the same in the consecutive floor of a building.
• The minimum vertical space or headroom above any step or the stair should be 2 m.
• Generally, the number of risers in a flight should be restricted to 12.
• The width of the stair should not be less than 850 mm. The standard width of any stair may be between 1.1 to 1.6 m. In public use buildings like malls, cinema, shopping center larger width of stair can be used.
