Scope of Works.

The purpose of this Method of Statement for blinding concrete is to outline the materials and labor required to undertake the works in a safe and controlled manner, compiling with relevant legislation, standards and codes of practice etc.

The method statement shall be briefed to all appropriate operatives to ensure that they are aware of the sequence of activities and any Client/Consultant project specific requirements.

A constant monitoring and supervision duty shall be undertaken by contractor to ensure work activities are carried out in accordance with the method statement. Any irregularities shall be immediately action.

This method statement describes the working procedures for blinding concrete and all related activities. This will include surface 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.
