5.3 Detail Procedure
5.3.1 Preparation and Survey work
- Prior to the commencement of excavating works, the surveyor will establish control points in
suitable locations to control excavating area, confirming the construction drawings of excavation
areas to be attached as addition to this method statement distribute details to all concerned
parties as required.
5.3.2 Excavation work
- Excavation shall be done in a safe and sequential manner on the basis of the prepared plan
drawings and in accordance with the instructions by the Engineer.
- The excavation method is either machine, manual cut or both and take care it to not disturb the
soil below.
- During excavation, it is necessary to make drainage ditch slope to sump pit as precaution in
case raining and ground water occurs during construction.
- Ground water will be drained by water pump with hose line is allocated to sump pit then
discharge to the river. Contractor shall monitor ground water level and continuously run the

dewatering pumps to maintain dry working platform when ground water is encountered.
Additional pumps will be added if the pumping capacity is insufficient.
- Excavated soil to be loaded to dump truck and transported to the stockpile. Unsuitable material
and waste material shall be removed from site to the waste yard in accordance with the
specification requirements.
5.3.3 Excavation up to design level
- During excavation, pile may be cut above the design cutoff level if necessary. Excavation shall
be taken care between the piles using small bucket (< 0.5 m3) or manual shoveling.
- After completion of excavation, dimensions and elevation of bottom area will be checked by
surveyor. The bottom will be leveled and compacted.
5.3.4 Sand back filling
- After completion of foundation concrete work and other concrete work under the ground, sand
back filling will be executed in uniform horizontal layers across the full area of the foundation
without segregation.
- Approved suitable material should be used for backfilling. Compaction standard shall be
employed in the execution of this work.
- Fill materials shall be distributed evenly to the backfill area to a specified thickness of
compaction = 150mm thick and compacted by compactor to a specified compaction factor.
Sprinkle water to the earth fill in compliance with the allowable moisture contents specified
before start compaction.

- Termite material shall be submitted by the separated document to the Engineer for approval
before start work.
· Application
- Application procedure shall be submitted by the separated document to Engineer for approval
before start the work.
6. QUALITY CONTROL
· Compaction of Backfilling
- After excavation, the bottom surface of pit shall be compacted to not less than 95% of
maximum dry density by vibratory plate compactor and the slope shall be trimmed off to avoid
collapse of pit wall.
- The fill material shall be checked and accepted by the Engineer before carrying out the work.
· Survey of excavated area
- After completion of excavation, dimensions shall be checked and recorded as attachment 1.
Tolerance of bottom elevation is ±10mm
7. SAFETY CONTROL
· Fundamental Policy
- “Safety is the First Priority"
· Key Activities
- Implementation of Safety & Health Education
- Prevention of Heavy Machinery Accidents
· Development and implementation of Activity
- Implementation of Safety & Health Education
- Pick up hazardous factors of each work activity and always reflect them at the safety meetings.
Point out them every day at the meetings in order to let individual worker to renovate his safety
consciousness.
- Prevention of Heavy Machinery Accidents
- Be consistent with inspection at beginning of works (including working ground), regular
maintenance of machineries, designation of working area and provision of a proper signalman.
· Others.
