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.

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.
Approved

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.

or storage shall be removed from the site and to be replaced with acceptable
materials.

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.
