Important points Civil Engineers must know(site engineers)

1: Weight of first Class brick should be not less than 3.85kg.

2: The Tensile strength of first class brick should be 3000 lbs / sq.inch

3: The normal Height of the building should be 215 cm

4: One Hook length should be get with 9D formula where the D is dia of bar which used in stirrup.

5: Firs class brick should be absorb water 1/5 or 1/6 of brick weight.

6: Thickness of DPC should not be keep less than 2.5 cm

7: Normal Heigh of the window should be 315cm

8: The staircase Riser height of should be 6 cm which is too much comfort for the public.

9: The lintel thickness should be 15 cm

10: Normal and Local sand FM limit should be 0.5 to 0.8

Important points for Civil Site Engineers

1: The compressive strength of Bricks should be not less than 3.5 N/mm2

2: Water Absorption for 1st class bricks should be not less than 15%

3: Use the formulas: D2/162 to find the unit weight of steel in kg/m where D is dai of steel in mm

4: Longitudinal reinforcement should not be under 0.8% and over 6% of gross C/S
