Errors that are almost common in the field of civil engineering

I want to repeat again about the mistakes that often occur in the field work, especially the civil engineering world.
Previously we have seen and work, and learn from experience we often encounter, from my experience working as field supervisor of the building project, this is often me encountered when the construction worker wrongly connecting the steel reinforcement, the worker connect the iron with the appraisal logically his thinking,

Then I as a direct field supervisor reprimand the error in the connection of iron, then I immediately explain the procedure of the iron connection terms that is by using the formula, because the iron has a tensile force, when we incorrectly connect it will affect the force of the earthquake, strong force Press concrete and affect on structure ..

Well, i will show an example of the picture I have made, with this picture maybe friends who work in civil engineering world will be easier to understand it,

This is what I can Post simple and easy pictures for everyone, especially for those working in civil engineering world is already familiar,
More and less I am Hive account@aguess please apologize to readers and for those who see it,

That thank you..
