Points to Remember for Civil Site Engineer

Civil Site engineer carries out multiple tasks on the construction site and repetitive works occur. So, some ideas, tips and tricks that an engineer needs to remember as fast solutions to construction problems for quicker calculations.

Points to Remember for Civil Site Engineer
There are then few items that civil site engineers can note to promote construction work while preserving building efficiency.

  • Bars with diameters greater than 36 mm are not permitted to be lapped.
  • The average distance between the chair is 1.00 m (or) 1 No per 1 m2.
  • A minimum diameter of 12 mm should be used for dowels.
  • Minimum chairs to use with a diameter of 12 mm bar.
  • No less than 0,8% and no more than 6% of total C / S reinforcement.
  • The square column minimum bar is 4 nos and the circular column is 6 nos.
  • Minimum bar in slab shouldn’t be less than 10 mm ( 8 mm for HYSD).
  • The slab is at least 125 mm thick.
  • Tolerance size + 2 mm for cubes.
  • A maximum of 1.50 m are required for free fall of concrete.
  • With bars dia than 36 mm, lap slices must not be used.
  • The absorption of water from bricks does not reach 15%.
  • The water does not have a pH value below 6.
  • Bricks’ compressive force is 3.5 N /mm2
  • The appropriate binding wire is 8 kg per MT in steel reinforcement.
  • 3 samples should be collected for the core cutting test per 100 m2 during soil filling.

Density of Materials

Reinforced concrete2310 – 2700 kg/ m3
Concrete block1920 kg/ m3
Bricks1600 – 1920 kg/m

Curing time of different types of cements for R.C.C members:

  • 7 days for Super Sulfate cement.
  • Almost 10 ( ten) days for (OPC)  Ordinary Portland cement.
  • minimum 14 days for Minerals & Admixture added cement used in construction

De-Shuttering time for different types of RCC Members:

  • 16 to 24 hours for columns, walls, vertical members and vertical from works.
  • 3 days for soffit for form works
  • 7 days for soffit to beams props
  • Almost 7 days for beam ( span upto 4.5m)
  • Almost 14 days for beam ( span over 4.5m)
  • Almost 14 days for arches ( span upto 6m)
  • Almost 21 days for beam ( span over 6m)
Also for a good engineer, its very important to maintain construction quality.
