Scope of Works.


The purpose of this Method of Statement for block work 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 block work and all related activities. This will include storage of materials, mortar, block work layout, laying of blocks, and curing.

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 (blocks, Block Accessories) are approved by Consultant.

MEP conduits and accessories lay out and installations has been approved by Consultant.

Method of statement was approved by consultant.

The Site Engineer shall ensure that the necessary Statutory Authorities approvals have been received.

 Reference.

 Approved drawings for construction.

Contract specification.

Approve project quality & safety plan.

Approved Material Submitter.

Approved Method Statement.

Delivery Storage & Handling.

Store delivered blocks on elevated platforms in dry location. If blocks stored in not enclosed location, cover the top & side with waterproof sheeting’s and securely tied. If block becomes wet, do not install until they dry.

Store cement materials on elevated platforms, under cover and in dry location. Do not use cement materials that have been damp.

Store aggregates where grading and other required characteristics can be maintained, and contamination can be avoided.

Store block accessories, including metal items must be stored properly to prevent accumulation of dirt and oil.

Materials which have been cracked / damaged during delivery or storage shall be removed from the site and to be replaced with acceptable materials.

Mortar.

For ready-mix: refer to the approved material submitter and manufacturer recommendation for application details. The ready-mix materials shall be kept in proper storage to protect it from moist.


Laying of Blocks.

Block work layout / setting out of wall must be check in advance for accurate spacing of surface and bonding pattern with uniform joint thickness and accurate location of openings, movement type joints return and offsets. 

Avoid using less than half size unit of blocks as much as possible, particularly in the corners, jambs, and where possible locations. 

If cutting is required to provide a continuous pattern or to fit adjoining construction joint, cut blocks with motor driven saw (hammer cutting not allowed) to provide clean, sharp, chipped edges.

Allow blocks to dry before laying unless wetting of blocks is specified. Install the cut block with cut surface and where possible cut edges to conceal.

Concrete slab surfaces shall be clean and tidy prior to the start pf block work activities. Concrete surface that will have direct contact with the block wall must roughened accordingly.

The Site Engineer with the Foreman shall set the first course of block work as per approved shop drawing.

Existing concrete surface where the block work is to recommence shall be wet before work starts.

Block shall have the correct thickness of mortar and all joint shall be pointed as work proceeds.

The first course will be laid in full. Blocks behind distribution board and electrical panel boards shall be solid or filled with mortar.

After completion of the first course of block work. Inspection request shall be raised for the QC Engineer / Consultant to check and approved the works.   

All block work shall be set out and built to the respective dimensions, thicknesses and heights as shown in the approved drawings.

All walls and partitions in the drawing without indication to the type of bloc to be used, shall be submitted for RFI prior to approval of the consultant.

Block work shall be built in maximum 6 course / layer in one day.

All block wall shall be checked vertically and horizontally, and all joints will be inspected for uniform thickness.

All block walls shall be bonded to adjacent reinforced concrete structures by approved galvanized steel ties at every third course to be fixed using nail gun.

Add wall ties between block wall and slab or beam for every 1200 mm as per approved material details.

All block work shall be provided with galvanized expanded mesh (as per approved material) every 3 layers or as per approved detail.

Approved material for expanded mesh must be added in every corner of block wall (T/L section) including the chasing for MEP services. Refer to the approved detail.

Top course of block walls and partitions that terminated at soffit of beams / slabs shall be built with full size block (cut pieces in not advisable).

All blocks around the openings must be solid (as per approved detail).

6 layers of solid block must be used for toilet walls.

Restraint post shall be provided at 6-meter intervals. Horizontal stiffener beams shall be provided in the wall does not exceed 4-meter height.

QC Engineer / Consultant to witness the depth of drilling holes prior to chemical application for steel post anchoring.

Concrete lintel shall be used as per approved detail.

 Fire resistant product for fire stops shall be of appropriate type suitable for specific application in specification (refer to the fire zone area in the approved drawing).

Block wall shall be built so that the gap between the top of wall and soffit of beam / slab is 10-mm minimum and shall be packed by backing rod (for fire rating zone area indicated in approved drawing).

Install control joint materials (filler board) as block work is in progress. Do not allow materials to cross in control joints without provision to allow partition movement.

Construct vertical and horizontal control joints as per the location mentioned in the approved drawing.

All block walls and partitions shall be cured by sprinkling water 3 times a day for a period not less than 3 days after installation.

Construction Tolerances for Block Work.

Courses: Level and true to line.

Faces, angles, and features: should be in Plumb.

Permissible deviations:

Position in plan of any point in relation to the specified building reference line and/ or point at the same level       ± 10 mm.

Straightness in any 5 m length        ± 5 mm.

Vertical up to 3 m height              ± 10 mm.

Vertical up to 7 m height              ± 14 mm.

Overall thickness of walls               ± 10 mm.

Level of bed joints up to 5 m           ± 13 mm.


Testing for Block Works.

Compressive strength of blocks must be check as per the following limits, solid blocks must be not less than 7 to 10 N/mm2 and hollow blocks must not be less than 5 to 7 N/mm2. Random checking will be done.


Repairing, Pointing and Cleaning.


All block that are loose, chipped, broken and stained or otherwise damaged shall be removed and replaced. This shall be installed in fresh mortar grout and pointed to eliminate the evidence of replacement.

Pointing – During the tooling joints, the voids, and holes shall be enlarged except for the weep holes and shall be filled with mortar. All joints including corners, openings, and adjacent construction shall be pointed to provide a neat and uniform appearance. Where required, joints shall be prepared for the application of sealant.

In progress cleaning – clean the block wall masonry as work in progress by brushing to remove mortar fins and smears prior to pointing the joints.

Final Cleaning – any mortar is thoroughly set and cured; the masonry will be cleaned as follow. Any large mortar particle will be removed by hand with wooden paddles, non-metallic scrape, hoes, or chisels.

Protection – do not uniform floor or roof load for at least 12 hours, concentrated load for at least 3 days after building the block wall or column. Where required during the construction, cover the top of walls, projection, or sills with waterproof sheeting at the end of each day work.

Prepare and issue and Inspection Request for Final Inspection.
