have been completed and signed-off by the Consultant:
Drawing must be approved
for construction by the
Consultant.
Materials Submittals (Cement board,
Framing Stud, Track, screws, and joint filler material
are approved by Consultant.
Method of statement
was approved by consultant.
The Site Engineer
shall ensure that the necessary Statutory Authorities
approvals have
been received WIR for completed concrete works should be approved.
Repairing of concrete surfaces
prior to framing works.
Ensure all necessary protection to be provided to existing Structure, floor, Services and Ceiling against any damage.
Erect scaffold and access platforms in accordance with approved documents and safety procedures.
A toolbox talk will be initiated by the HSE Team to the personnel who will perform this activity.
Review the relevant documents to verify whether the preceded activity was completed and approved by the consultant.
QA/QC Representative will verify that all the apparatus and instruments used to check the quality of material and conditions were all calibrated with supporting documents.
Allocate a dedicated Site Engineer to supervise this activity that will ensure that this Method Statement, ITP, and other specific documents related to this activity.
Delivered materials should be verified by the QA/QC Representative and has to be inspected by the Engineer.
Store materials in dry area out of direct sun
light and as directed by the material manufacturer.
Delivery Storage and Handling.
Cement Partition and lining materials (Cement
boards, insulation's (IF REQUIRED) and Framing components), with delivery note
to be delivered to the site accordingly and
Stored, protected against from any damage.
Execution.
Layout Marking or Setting Out.
The team will conduct a
survey for specific layout marking as per Site Personnel.
The Team will carry out
layout marking as per approved drawing in accord with the
schedule of work.
The layout would be mark
with any marking line on the floor and subject for correct layout. Once the
setting out is completed, the end points will be marked with permanent markers.
The level and line for setting out would be taken from the approved Drawing
from the Contractor at site.
All layout and markings will be checked before proceeding with
the installation.
Check for right angle and alignment of the framing / first
fix
Framework for Partition.
Fixing the bottom Track to the floor matching the layout on
the floor which have been marked before starting the fixation.
Fix the first and last vertical stud only for each expected
wall partition and in the same time fix the top track to check the
alignment.
The floor tracks will also be fixed in the same manner.
The stud will be installed between the top and bottom@600 mm
Center to center tracks taking into consideration the height of the partition and joints of
studs to overlap 600 mm in both directions.
Around opening doors and A/C Ducts should be taken into
consideration for extra support channels, as horizontal track, and vertical
stud in position to receive flat faces.
The framework will inspect by Site In-charge for any
discrepancy, to rectify, if any, before proceeding the work.
Rock wool insulation “if required” and Boarding for
Partition.
First will start with Installation “if required” of First
layer one side Cement board keeping 20
mm of space around the outer frame and ducts openings for
the fire sealant “If Applicable”
to be applied
Second will put the insulation inside the partition
structure making sure of dimensions and
keeping the insulation tight inside the structure of the
partition.
After the cutting and fixing of both side Cement board, it
will start the Second layer of fire
rated gypsum board and then start the joint treatment with
fiber tape and assuring that joint
level is not exceeding the board level.
Boards will be installed along the stud direction with
plasterboard screw or using the required accessories and metal angle as per approved materials and
drawing.
The joints between each board are covered with Fiber tape.
After fixing the joint fiber tape,
the gap be filled with Putty and the surface must be smooth
using sandpaper.
Taping, Jointing and Painting.
The substrate shall be fully cured and prepared to the
required surface finish prior to
commencement of painting.
The substrate shall be free from dust, oil, grease, and wax
contaminants etc.
The substrate shall be repaired if the surface has imperfections.
Appropriate repair products
shall be used.
Any MEP embedded items (Switches, power supplies etc.) shall
be fully sealed and signed-
off.
First coat of joint filler should be applied with Tools of
Sufficient width to extend a minimum
of 50 mm beyond both sides of the center of the Joint.
Joint tape to be embedded into the joint Filler to reinforce
the joint between the Cement
Board.
Second Coat joint
filler will be applied over the dried first Coat.
Once the Second Coat is dried, surface should be sanded and
smoothed.
One coat of Primer will be applied over the board
joints.
Another One coat of
Primer applied over the entire Partition Area.
