Basic things to learn for fresher civil
engineer:-
This post is only on Site work (Checking
& Managing).
Checking
Let’s go
with basic checking like
1.
Column checking
2.
Slab checking
3.
Concrete checking
4.
Footing checking
As
a civil engineer we have to check R.C.C work & Shuttering work (form work)
as well as finishing work
which is very important.
Column Checking:-While an engineer goes for checking column he/she
should know what things should be checked in column
1. Center line
2.
Starter or Column
3.
Concreting
As there is practice of direct making column mold without starter .I have
written starter or column in check list.
First we should know what center line is, Center line tells us what is
the position, phase, center point of column.
For checking center-line of column one should have center-line plan and he/she should check the column
number which is to be checked and the column distance in x and y direction
which is in plan given in terms of distance between column which is to be
checked and other column in that alignment.
After checking the distance you should get the appropriate distance
between two columns. IF you get the correct distance mentioned in drawing by measuring
that distance with measuring tape your column is in proper position now you can
set up the starter or directly set up the mold for column that depend upon the practice
of an engineer.
Now checking goes in 2 type
R.C.C and Shuttering.
Shuttering:-
As the mold of column is set you should check the shuttering material do
it has leakage or hole and the alignment of column (vertical & horizontal).
In Indian site language if we say (modhia
aur side line me hona chaiye).
Check if proper oiling is done on mold from inside. Proper oiling of mold
helps in god finishing smooth surface and it becomes easy to remove shuttering
without damaging shuttering.
After this you should check the plum of the column that is column is on
900 not tilted it is checked with help of plumb bob.
Column has four side so it is must to check plum on two side of column (longer
and shorter) side but on longer side on both end and in shorter side in the middle
and while checking plum you should check
at two point at top and at bottom
If you don't get same distance at top and bottom you should make carpenter make it correct.
In Indian site language we say it
as olamba should be equal at top and at bottom.
Last thing
to check in shuttering is Diagonal side it helps u in knowing is column proper
rectangular or it is not if no you should get it correct and check proper molding
is done or not
Both diagonal side should be equal
in measurement to maintain column rectangle in shape.
In Indian site language we say it
as katkona we should get same on both diagonal
side.
R.C.C (steel Checking):- In steel checking you should check the alignment of steel bar, number of
vertical bar and there diameter of bar as per given in the drawing(R.C.C
footing and column drawing).
Check the
links provided(Ring) if the number of vertical bar are more or steel dia is
bigger say 12mm,16mm,20mm it is provided
with Links and master link (Ring and Chipya, Master
ring).
And check
the master ring is provided alternately with links.
After checking this check if the links are tied properly with binding
wire.
AS R.C.C and Shuttering work is
checked now it’s time for concreting.
Concreting:- At time of concreting Engineer
should Check the mix proportion made by worker and homogeneity of concrete if homogeneity
is not proper he should adjust the aggregate, sand contain in the mix and Engineer should give the marking till what
length column is to be filled.
Calculation for what length
column to be filled
Floor to floor height=2.9m
Beam depth(beam having maximum
depth of all beam)=say 0.6m
The column to be filled
=2.9-0.6=2.3m
After getting the length to be filled on one column(blue column)Transfer that
length (level of filling) with help of level tube to all other column which you
need in same level.
While pouring the concrete the vibrator should be properly inserted and concrete
should be compacted to avoid honeycombing
and voids.
As concreting is in process tell the worker to check the position of
steel as it shifts as the pressure of concrete falls on it because if column
steel shifts it cannot be brought in proper place after concrete get hard which
will lead to improper distance of steel while shuttering again for further work
like slab and beam.
