All construction activities for building can be summarized in the following
manner.
5. SITE PREPARATION:
As the foundation work for all the structures for this site are already
complete. So that area around the structures will be properly prepared
for the accessibility of materials.
The surveyor (both Engineers & Contractor) will identify benchmarks
and finalize them jointly in accordance with all the terms and
conditions.
Before setting out any activity, all levels /elevations will be determined
first.
6. SETTING OUT/CARRYOUT:
The surveyor will layout before execution of any activity.
7. FORMWORK:
Before start of formwork, surveyor will mark the points/line and will
convey this information to area Foreman/Incharge.

inspection and approval before placing of steel.
METHOD OF STATEMENT
Engineer will confirm the acceptance of this activity after review of
these items in writing.

on steel reinforcement where required.
Supports will be provided where required to keep the reinforcement in
position.
Where anchor bolts or any embedded item, the foremen/site supervisor
will ensure that these arrangements are securely tied with rebar/welded.
Once the steel reinforcement is completed, the engineer will be
requested for necessary inspection and approval before concreting.
9. STRUCTURAL CONCRETE:
When the steel request approved by the Engineer in writing and
allowed for proceedings further then necessary arrangements will be
made for concreting.
An approved ready mix concrete supplier will supply the structural
concrete for approved mix design if necessary before transportation
concrete mix, the Engineer will requested to Visit the mixing site.
Concrete temperature shall be checked.
Temperature of water shall be checked.
Pouring will start after clearance from Engineers
Mechanical type of vibrator will be used for consolidation of concrete.
The size of the vibrator will be selected depending on volume of the
concrete in pour and space available.
Care will be taken to maintain the Engineering properties of concrete.
METHOD OF STATEMENT
10.
Removal of formwork will be in accordance with the authorize
limitation for achieving the desired strength of concrete.
A due care will be adopted to avoid any damage to concrete during
removal of formwork.
11.
TERMITE TREATMENT:
The chemical used for anti-termite proofing would be got approved
from Engineer.
Once the approval from the Engineer is obtained, then the termite
proofing will be carried out where required, i.e Timbering, under the
floor foundations before and after earth filling.
14.
PROTECTIVE COATING:
After completion of the curing period, hessian cloth will be removed.
Application of 2 coats of approved bitumen paint shall be carried out at
required places.
The acceptance criteria for protective coating will be according to the
relevant specification as approved by Engineer.
13.
CONCRETE CURING:
Immediately after pouring & completion of the surface finishing in any
section, the exposed surfaces shall be left for the hardening.
Freshly placed concrete floor shall be placed protected to prevent loss
of water by covering with damp hessian cloth.
Concrete shall be kept constantly damp for to authorize the desired
strength as mentioned in specification
Concrete pouring date & time will be written on each sample.
12.
FORMWORK REMOVAL:
BACKFILLING:
The backfill material will be sourced from suitable/approved site.
Backfilling material will be placed in layers according to the
specifications
The layers will be moisturized and compacted to 95% compaction
Compactions will be done by compactors
The compacted surface will be approved by Engineer on request.
METHOD OF STATEMENT
An acceptable test layer approved by Engineers will allow the next
layer of backfill to be placed.
This process will continue until the structure is completely backfilled.
15.
After completion of termite treatment, Bitumen coating & Backfilling,
following steps will be followed.
Lean concrete 2 thick will be placed on compacted fill material
After curing of 2 PCC blinding, polythene sheet of 1000 gauge shall be
placed.
BRC wire mesh (200X200X6mm) on concrete spacer block.
