WHAT IS PEDESTAL IN FOOTING ?

 During foundation you should always be careful that there is no water present in the excavation pit and the depth should be accurate. So for that you need manwork and labourers to maintain it's accuracy. So before going further for any work just be careful that the depth of foundation is accurate and no error should be made. Because the structure of a building is fully depend upon foundation. And this is general sense that the all the building loads are carried to the foundation i.e., footing. 

Before doing any foundation work first of all brick soiling is to be done or sand filling. The building where high rise structures are made, sand filling is done; but the house with ground floor, brick soiling is sufficient. But from where you will get the bricks. Obviously you will have to order or bring it from bricks factory where bricks are made. And after bringing the bricks where you will placed them?  (Actually all these practical knowledge are not taught in the college so you will have to build up your own practical skills by learning at the site.) So just see at the site if there is a free space living there, if there then then stag it with proper order with the help of the workers. And after that you can use it for your work. 

Okk, now there are some important steps you should have to follow during foundation and pedestal column. No matter how much difficult the work is, but the main important thing is that you should have to be careful for the starting days while making the foundation. Because, one silly mistake can make the whole structure fail. 

There are many specific mistakes that the mistry makes during foundation work. First of all he dosen't make cutting in the accurate level which later becomes difficulty in placing the shuttering. Second thing he should have to clear out the water from the excavation pit. This seems to be difficult but by using water pump it makes the work easy. The shuttering should be placed in right position at 90 angle. 

There are also many different kinds of situations happens at the site such as briming up of water level above foundation, Column head not placed in proper position, mix of concrete is not appropriate etc. all these things can happen. 

Just careful about the failures that happens at the site. Some failures such as seepage of soil, loosen soil. Rise of water level, unnecessary rubbish falling at the site, using wooden bit at the site for foundation. All these small small things should be taken care of.
