Introduction

An eight storied residential building have two parts. These are

sub-structure and super-structure.

In a construction process both theoretical knowledge and practical work

are equally important.

The longevity of construction work depends on monitoring of a ‘Site

Engineer’. So he is an important person of a project.

7

Objective

The main objective of this project is to plan over constructionand to progress the construction process.

To acquire practical knowledge.

To increase monitoring work during construction process.

To decrease amount of wastage materials.

To optimum use of time and manpower.

To make the project economical.

SlabForm work procedure:

After completed the column casting work, start slab with beam centering.

Use bamboo posts @ 2' c/c for slab centering.

After that use timber for slab centering.

Fixed the end of steel sheet with wood by nails.

Level the form of slab.

21

Figure: Centering of slab

Reinforcement placing:

Bottom layer:

Binding for bottom layer

reinforcement, mainly use two

categories.

First one is short direction

reinforcement.

Second one is long direction

reinforcement.

22

Figure: Slab reinforcement placing

Crank bar :

Crank bar should be used in both way of slab.

Extra top bar:

Extra top bar are to be used on every crank bar.

23

Clear cover:

Clear cover 1" was taken

in every slab.

Figure: Clear cover of slab

24

Slab Casting:

At first slab casting by

concrete.

After that concrete place in

column and beam joint,

then concrete place over whole

slab.

Carefully compaction of concrete

by Vibrating machine.

25

Figure: Compaction of concrete

Brick WorkWorking procedure of brick

wall:

Select the first class bricks.

Chipped and cleaned the

surface and made layout.

Joint mortar was proper compacted by steel

trowel.

26

Figure : Brick work

English bond was ensured.

Vertical and horizontal alignment was maintained.

1st lift brick work was, for 5" wall 4' and 10" wall 5'.

Curing for 14 days was ensured.

27

Lintel Work

Working procedure of lintel:

After completed 7' height brick wall,

lintel mainly made above the door and

window.

For large span lintel used bamboo

posts.

According to wall wide, completed the

centering and shattering.

28

Figure: Lintel centering and shattering

Fixed the end of wood with brick wall

by nails.

Used reinforcement in lintel.

Casting properly, ratio is 1:2:4.

Properly curing at least 7 days.

29

Figure : Reinforcement place in lintel work

Preparation of background:

At first clean the masonry and RCC surface properly.

If any part of the walls so high, then cut the high part.

The surface of wall kept moist for at lest 6 hours before plaster is started.

30

Figure : Preparation of background

High part

Preparation of mortar:

1

In my working site, there

weren’t reputed

contractor and experience

full subcontractor.

I informed project manager.

Then he changed them and also

employed new contractor and

subcontractor.

2

Contractor didn’t

maintained proper work

schedule.

I regularly communicated with

them and increased observation.

So many unskilled mason

and labour were in my

construction site.

So, I have tried to handle

unskilled labour and mason and

sometime trained them.

SL. Problem Identified Suggestion

04 Building project neighbor

side there were no proper

safety of during construction

time.

I used Hessian cloth with

bamboo bracing to project

neighbor side, from the brick

bats, plaster mortar etc.

05 Suppliers didn’t supply

good quality sand, during

plastering work.

I have informed to the top

management and they

supplied good quality sand.

39

Conclusion

Durability of a building depend mainly on proper construction process and

proper use of materials.

I have supervised slab work, brick work, plaster work, sanitary & plumbing

work etc.

After supervision of my construction site, I have learned a lot about

theoretical background and achieve practical experience. It seems to me

that the practical knowledge is essential to be an efficient engineer.

40

Recommendation

Standard quality of material should be ensured first

Leakage into joint of formwork should not allowed

Unclean reinforcement should not used

During casting vibrator should be straight instead of inclined

Before casting vertical and horizontal level should be checked for all

formwork

Every day before closing of works, the site should be cleaned
