In this article today I will teach you the 12 important points for civil Site engineers which are too much important at site.
Given are the point which should be apply at the Site
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
5: Use minimum 4 No’s of bars for Square column and 6 No’s of bars in Circular Column.
6: During concrete work Free fall of concrete should be not more than 1.50 meter.
8: We should not use the lapping length if the dia of steel is over 36mm
9: Earthwork excavation toward basement over 3 m should remain in stepped form
10: Electrical conduit shall not be runs in the columns.
11: Cement should be preserved in dry places on a raised platform roughly 200 mm
12: Main bars Diameter should not be less than 12 mm.
Note: The above information are too much important specially for Civil Site Engineers to keep these point and implement at site.
