Basics of Civil Engineering:Part-I
1. Height of building = 3.15m.
2. Height of Parapet wall should be 1m.
3. Height of window = 2.1m.
4. Minimum thickness of slab = 125mm.
5. Minimum thickness of lintel = 15cm.
6. Thickness of DPC = 2.5cm.
7. Maximum diameter of the bars used for lapping is 36mm. Bars having more than this diameter are not allowed.
8. Minimum diameter of bars used in Slab = 8mm.
9. Minimum diameter of bars used in Column = 12mm.
10. Minimum number of bars used in Square or Rectangular Column = 4 bars.
11. Minimum number of bars used in Circular Column = 6 bars.
12. Maximum diameter of bars used in Slab = 1/8 x thickness of slab.
13. Maximum Chair spacing = 0.75m.
14. Chairs minimum of 12 mm diameter bars to be used.
15. Minimum diameter used for Dowels Bars is 12mm.
16. Longitudinal reinforcement should not be less than 0.8% and not be more than 6% of gross area of cross section.
17. Binding wire required in steel reinforcement is 8kg per MT.
18. Weight of 1 cement bag = 50kg.
19. 1 bag of cement = 1.25 cubit feet =0.0347 cubic meter.
