4) METHOD STATEMENT:-
4.1) SERVICES/UTILITIES IN THE VICINITY OF WORK:-
4.1.1)
List of services:-
There are no services running along the work area. The sheet piling works have been completed already. Trial trenches were done before the sheet piling works
to ensure the absence of any services within the work area.
4.1.2) Protective measures:-
Even though there are no services running exactly below the piling area, there isa 500mm AC Main at a distance of 7.5 meter from the bakau piling area. Care
is to be taken that no unsafe acts are carried out near the AC main. Regular
checks are to be carried out to look for any possible leakage in the 500 AC
Main.
4.2.2) SEQUENCE OF BAKAU PILING WORKS:
1) Set out the proposed 1500RCU drain alignment as per setting-out plan.2) Excavate the trenches to the required depth for the laying of precast RC U-drain.3) When the excavation reaches the required depth, Start the installation of Bakau
piles.
4) Bakau piles are installed with the help of the Steel Dolly attached to the teeth of the excavator bucket.
5) The length of the metal dolly is 3m. The depth of excavation is 2.5m whichmeans that the entire excavator bucket will be above the strut area when the
bakau piles are completely installed.
6) The work sequence is;
The bakau pile is placed in the required location and is pressed into the soil bythe workers up to possible depth.
The workers are then to move away from the pile. The dolly attached to the excavator bucket is then lowered and the bakau pile is
inserted into the hollow part of the metal dolly. If necessary, worker will assist
in inserting the pile in to the dolly.

The metal dolly is the pressed down gradually until the whole length of the bakau pile is inserted into the ground.
The dolly is then lifted up with much care to prevent it from hitting the workersnear the work area.
The next bakau pile is placed 300mm from the previous pile and the same process is continued.

SAFETY PRECAUTION
1) Work site shall be cordon off from public access.
2) Proper barricade and signage shall be provided to warn the workers to divert
away from deep excavation
3) Work area must be cleaned and stagnant water cleared daily.
4) All workers shall wear Personal Protective Equipment e.g. reflective safety vest,
safety helmet within the site.
5) Site supervisor shall supervise throughout the entire piling works; he is wholly
in-charge of safety, supervision and traffic control in work areas.
6) Where excavators are used, care shall be taken to ensure that no materials are
stacked within the swinging area of the excavator.
5) EMERGENCY PLAN:-
5.1) EVACUATION PLAN:-Upon the occurrence of work site accident, the emergency evacuation plan is as
follows: Site work in the vicinity will be stopped The reporting of the occurrence of accident will go up the company hierarchy
i.e. workers inform supervisors/engineers, who will inform the project manager,and then the RTO and LTA will be informed
Site and safety supervisors will be taking charge of securing the area Any hurt personnel will be carefully shifted to a secure location for first aid and
subsequent evacuation to nearby hospital Unhurt work personnel will be gathered at a safe with headcount accounted for.
They will receive further instructions Accident area to be investigated and subsequently cleared.
