preparation, application, testing and post application.
General.
Prior to works commencing, the Site Engineer shall ensure
that the following activities have been completed and signed-off by the
Consultant:
Drawing must be approved for construction by the Consultant.
Materials Submitting for blinding / screed is approved by
Consultant.
The Site Engineer
shall ensure that the necessary Statutory Authorities approvals have been
received.
Reference.
Approved drawings for construction.
Project specification
Section.
Approve project
quality & safety plan.
Approved concrete
materials.
Approved Inspection
of preliminary work (Back filling, anti-termite, and level verification).
Blinding Procedure.
The excavation and back filling shall be completed up to the
designed foundation level. All appropriate forms shall be signed-off by
Engineer.
All compaction test
report shall be approved before proceeding with blinding works.
Surveyor will
validate the level based on the approved drawing and marking around the
blinding perimeter will be provided.
All extra soil and
loose material shall be removed from the excavated area where blinding is to be
done.
Anti-termite
treatment shall be applied if required based on the project specification.
Separate method of statement will be submitted for the application of
anti-termite.
Plastic protection (polythene
sheet) will be provided as per approved material submitter.
Spot reference level
marks to be provided using sand and cement mortal (1:3 mix) or steel pieces.
The top level of the reference point indicates the designed blinding finish
level. The spacing between reference points shall not be more than 3 meters in
any direction.
Side shutter shall be
fixed as per approved drawing and marking was provided by the surveyor.
Finishing level
should be marked on the side shutter.
The concrete shall be
in accordance to approved mixed design from approved concrete supplier with the
required compressive strength of C12/15 or 15 MPa cube strength at 28 days.
Casting will take
place using mobile pump or concrete bucket depending on casting quantity and as
per site condition.
Blinding levels shall
be determined via level mark.
Curing will be done
as per project specification. No activity will take place without completing
the required curing period as per specification.
Testing.
Compressive strength (cylinder/cubes) C12/15 as per project
specification. Sampling collection will be every 50 cubic meter, 2 cubes for 7
days, 2 cubes for 28 days and 2 cubes for spare.
