The plan of boundary
wall and we have taken the scale ¼ inch is equal to 1 feet.
There are two
columns. There is a centre line (denoted by CL) for the boundary wall. There
are two centre lines for the columns. The foundations for one column are 3 feet
and 3 feet and for second column are 2.5 feet and 2.5 feet.
But, keep in mind
that the actual dimensions of both the columns are 13.5 inches and 13.5 inches.
The breadth of the wall is 9 inches. There is one inside and one outside of the
plan. There is a plaster. The length of the wall is between two columns is 12 feet.
Now, let us see the
elevation for outside of this column. It will show the NGL which is natural
ground level FGL which is finished ground level (inside). The height of the
column or the height of the wall is 7 foot and 6 inches. The walls are continued
from both sides.
The cross section of
the column will show the dimension of the column which is equal to 2.5 feet and
the other column is 3 feet. The scale is 3/8 inches is equal to one foot.
Now, let us examine
the cross-section for the column. It uses the class D concrete. Depth is 6
inches and for the second step, the depth is 6 inches.
From foundation to natural ground, the depth from natural ground level to foundation is 30 inches.
When two sides are subtracted from the first step, then the second step becomes 22 ½ inches x 22 ½ inches. When two sides are subtracted from the second step, then the third step becomes 18 inch x 18 inch. 13 ½ inch x 13 ½ inches is the actual dimension of the column. It can be matched with top views and other views.

The height of the
column is 8 feet. For second column, the first step is 2.5 feet and the second
step is 18 inches and the third step is 13 ½ inches. The height of the second
column is 7 feet and 6 inches. We will use the mortar in 1:6 where 1 is the cement
and 6 is the sand in the first column. 13 and ½ inches brick masonry is used in
1st column. 9 inches brick masonry wall is in second column. For the column with foundation 3 feet, we
will use the plaster ratio as 1:4 where 1 is cement and 4 is sand.
Deep struck pointing
is for column having foundation equal to 2.5 feet. For column with foundation
equal to 3 feet, there is ¾’’ Groove in plaster at D.P.C. level.
