Following are some important points to remember for civil site engineers to make the construction work easier while maintaining a quality of construction;

  • Lapping in reinforcement is not allowed for the bars having diameters more than 36 mm.
  • Steel Char maximum spacing is 1.00 m (or) 1 No per 1m2.
  • In steel dowels, a rod minimum of 12 mm diameter should be used.
  • Steel Chairs minimum of 12 mm diameter bars to be used.
  • Longitudinal reinforcement should not less than 0.8% and more than 6% of gross C/S.
  • The minimum bars used for a square column are 4 No’s and 6 No’s for the circular column.
  • Main bars used in the slabs shall not be less than 8 mm (HYSD) or 10 mm (Plain bars) and the distributors not less than 8 mm and not more than 1/8 of slab thickness.
  • The minimum thickness of the slab should be 125 mm.

Civil Engineering Tips for Civil Engineers

  • Freefall of concrete is allowed maximum to 1.50m height.
  • Lap slices shall not be used for bar larger than 36 mm.
  • Water absorption of bricks limited not more than 15 %.
  • PH value of the water used should not be less than 6.
  • The minimum Compressive strength of Bricks is 3.5 N / mm2.
  • Binding wire required in steel reinforcement is 8 kg per Metric tonne.
  • For soil filling work as per IS code, 3 samples should be taken for core cutting test for every 100m2.

2) period for Soffit formwork to slabs – 3 days (props to be refixed after removal)

3) The period for Soffit to beams props – 7 days (props to refixed after removal)

4) Beams spanning up to 4.5m – 7 days

5) Beams spanning over 4.5m – 14 days

6) Arches spanning up to 6m – 14 days

7) Arches spanning over 6m – 21 days


Minimum Nos. Of Concrete Cube Sample for Given Volume of Concrete

  • 1 – 5 m3 = 1 Nos.
  • 6 – 15 m3 = 2 Nos.
  • 16 – 30 m3 = 3 Nos.
  • 31 – 50 m3 = 4 Nos.
  • Above 50 m3 = 4 + 1 Nos.

Who is the Father of Civil Engineer?

John Smeaton
John Smeaton (8 June 1724 – 28 October 1792) was a British Civil Engineer back in the 18th century and has since come to be known as the Father of Civil Engineering. His designs of ridges, canals, lighthouses, harbours and mills were a great milestone in Civil Engineering. His some works can be found across the UK.
