METHOD STATEMENT FOR BRICKWORK
METHOD STATEMENT
FOR BRICKWORK
1. INTRODUCTION / SCOPE
Ø This method statement covers the requirements, equipments and
procedures to be used for brickwork.
2. OBJECT / PARAMETER
Ø Following documents shall be considered as reference for execution of
the job:
a.
Architectural GFC drawings provided by
consultant.
b.
Site instructions.
3. MATERIALS
Ø Bricks, Cement, Stone Dust/River Sand, Water, 6mm dia. MS bars.
4. PRINCIPLE
Ø An assemblage of bricks properly bounded together in mortar is called
brickwork. In normal brickwork, the bricks are arranged and bedded in mortar in
such a manner as to form a homogeneous mass of the structure.
5. APPARATUS / EQUIPMENT
Ø Kanni, Plumb, Bucket, Thread, Scraper, Brick Hammer, Spirit Level or
Bubble Tube, Right Angle, Steel Tape, Fanti.
6. HEALTH AND SAFETY PROVISION
a.
The work place is to be free from all
kind of debris.
b.
Specific safety measures are to be followed
as applicable.
c.
All working platforms are to be
inspected.
7. PREPATORY WORK
a.
Obtain relevant approved GFC drawings.
b.
Chipping on the contact area of vertical RCC
surface to be done and chicken wire mesh to be fixed with cement slurry.
c.
Layout should be done as per the drawings
and the same to be approved by the Project engineer before commencing of brickwork.
d.
Arrange all materials such as bricks,
dust, cement and steel.
e.
Cement for next day early hour work to be
issued in advance.
f.
Empty cement bags, of 3’ width to be laid
before starting of brickwork.
g.
Arrange any support structure like
staging for working at heights.
8. WORKMANSHIP
a.
Face side of brickwork should have proper
joints cut (pointing) and all the joints on un-face side shall be filled with
cement mortar.
b.
In a brick wall no combination of face
and un-face side should be seen in the same wall.
c.
A definite pattern to be followed in the
entire project for the face and un-face side in the outer brick wall of the
buildings.
9. PROCEDURE
a.
Bricks should be cured within 30 minutes
before its use.
b.
Layout shall be done according to the GFC
drawing and same is to be approved by the engineer in-charge..
c.
Proper mortar mix should be prepared through
mixture machine only i.e. for 9” brickwork, 1:6 (1 cement: 6 stone dust), and
for 4.5” brickwork, 1:4 (1 cement: 4 stone dust).
d.
For 9” brickwork, brick shall be laid in
English Bond, unless otherwise specified.
e.
For 4.5” brickwork, brick shall be laid
in stretcher bond unless otherwise specified.
Stretcher Bond
f.
All loose material, dust to be removed from
RCC surface with wire brush and surface to be wetted with water.
g.
Chipping should be done on all RCC
members so as to remove any extra concrete on the slab/column and chicken wire
mesh to be fixed with slurry (on vertical RCC member).The total gap between RCC
and brickwork should not be more than 15mm ,this thickness includes
cement paste, chicken wire mesh and thickness of mortar.
h.
Brick are to be laid as per the layout,
on the bed of mortar, with frog of the brick facing upward and leaving mortar
thickness within a range of 10-15 mm on all four side of brick.
i.
Each brick shall be properly placed and
set in position by gently pressing into the mortar bed with handle of trowel.
j.
On placing the next brick, joints between
the two bricks is to be fully filled with mortar, so that no hollow space is
left between the bricks.
k.
Complete layer of brick is to be laid in
the stated manner.
l.
Instead of breaking full brick, brick
bats are to be brought in use and to be used as closure near the end.
m.
Brickwork should be in proper line, level
and plumb.
n.
Diagonal and right angles of the room
should be as per requirement.
o.
All courses should be laid truly
horizontal and all vertical joints in the alternate course shall come directly
one over the other.
p.
4.5” wall should be properly keyed in
main wall/partition wall, as and where applicable.
q.
1 number 6mm dia MS bar should be used
after every 3 layers of bricks in 4.5” thick brickwork.
r.
Last course of brickwork near beam/slab
bottom should be properly packed with mortar leaving no gap in between them.
s.
Brick joints on the face side should be
filled with mortar & should be raked out up to a depth of 6 mm.
t.
Joints on un-face side to be filled with
mortar and to be cleaned using wire brush/coconut broom, on the very same day
of brickwork.
u.
Mortar fallen on the laid empty cement
bag, is to be collected & brought in use at an interval of every one hour.
v.
Quantity of mortar prepared should be sufficient
enough, such that no mortar is left after the closing of work.
w.
Clean the area after finishing of work.
x.
Date of brickwork should be marked to
monitor the curing period.
y.
7 to 10 days curing should be done.
10. INSPECTION
a.
Chipping has been done.
b.
To check layout as per drawing with
dimension and diagonal.
c.
Mortar mixing is of specified ratio and is
done through mixture machine only.
d.
1 number 6mm dia MS bar should be used
after every 3 layers of bricks in 4.5” thick brickwork.
e.
Bricks should be cured within 30 minutes
before its use.
f.
Brickwork is in line, level and plumb.
g.
All the vertical joints in alternate
courses should be in the same vertical line.
h.
Area is clean after completion of work.
i.
Brick joints to be maintained 6mm deep.
j.
Date of brickwork has been marked.
k.
Joints have been filled and raked
properly.
