Following picture shows the shuttering used for slabs.
This kind of steel shuttering is very useful as it reduces the plastering works. More over wooden logs are hard to remove and also cause breaking of edges. The steel shuttering when used with proper oiling is much easier to remove and also offers excellent finishing. All large projects use this kind of shuttering, only small house constructions are still using wooden planks and that too only in developing countries
This procedure I came across in one of the site.Just for info to Beginners. This test is called WINSOR probe test.
When the concrete is done and its up and you want to know the strength of concrete with minimum damage,this is the one of the test.
Engineer will select the location.In this case its in column.

Follwing picture shows the shuttering for slab and beams at a construction site. On close inspection we can see that this picture shows the drop panels too.
Right click on the picture and click on view image to see the actual sized picture
The following picture is taken at a construction site and it shows the beam reinforcement. In any beam reinforcement, two things should always be kept in mind. These are Proper Lap and Ld
In case these are not properly provided as per the design the entire beam purpose is lost and beam loses its required strength. It has been found that if the beam is not properly reinforced, the entire structure is bound to collapse
The following picture shows how Piles are used to retain soil. Piles are very useful way to prevent the sliding soil. More over as we go deep and deep, excavation becomes a prime source of concern for site engineers as soil keeps on flowing. More over in some cases it can become a source of accident. So piles are a great relief to site engineers.
An image showing the brick wall just after construction. Its the stage before plastering.
We are thankful to Mr Satyendra K Sharma for bringing following points into notice:-
Picture of the wall shows that the masnory has been done without proper technical supervision.Following defects could be noted.
This picture shows the provisions of electric conduits before the concreting process.
This is the picture of water pipe which is placed for rain water drainage
This is the picture of fan box which is placed in the roof before its casting.
This picture shows the beam column junction. The steel seems to be piercing from each other but actually its arranged in such a manner that a proper beam column joint is formed
