Preparation of work area for Excavation
Erect warning signs to warn others of excavation work or trenches and the associated risks.
Where pedestrian access is restricted by excavation or trenching works, provide safe and adequate marked walkways for use by pedestrians around the works.
New workers on site must check with Site Supervisor for locations of all excavations.
Arrange for flashing warning lights and/or temporary lighting to be operational when dark.
Check for underground services – dial before you dig (DBYD) and note the service location, type, depth and any restrictions that apply;
Obtain any appropriate approvals from the utility or service providers.
Make sure that no conductive objects are in contact with or are likely to come in contact with any live conductors / overhead transmission lines etc.
Hand excavate if exact location of services is unknown.
Make sure nearby footings, slabs, walls or other existing structures are not damaged by excavation works.
Ensure that during the excavation structural engineering drawings and specification are followed.
Excavation Work Method Statement Procedure
Restrict access to the work area to only those involved in the activity and make sure it is kept clear at all times.
All workers must wear high visibility clothing and boots at all times, and hardhats, hearing protection, dust mask and gloves as required;
Provide clear access for vehicles to enter, exit and move on site.
Designate a responsible person to direct vehicles and do not stand on the downhill side or directly behind a moving or unloading truck;
Keep clear of the load gate when releasing the pin;
Check for overhead wires, structures and branches especially when tipping;
Ensure that the excavator operator has seen you if you are near by; and make sure trucks can exit steep or muddy sites when empty.
Make sure no workers enter an unsupported section of excavation or carry out any excavation work without supervision.
Shore up sides of excavation if ground is unstable or if greater than 1.5m deep.
Approved shoring methods include pre-cast panels, trench shields, soldier sets and sandbags.
Both benching and battering of walls are also methods of work which minimize the risk of rock and/or soil slipping into the excavation.
Compaction with a vibrating roller must not be carried out within 600mm of any utility infrastructure.
Make sure all excavated or fill materials are placed a minimum of 600mm away from the edge of the excavation.
Where excavated or fill materials need to be placed closer than 600mm from the edge of the excavation, make sure an effective barrier is installed to prevent them from falling into the excavation.
Make sure at least 2 workers are present on site at all times during the work activity in case of emergency.
Ensure that operator has the appropriate certificates or experience to operate the equipment;
Make sure the equipment is in good working condition and regularly maintained;
Wear high visibility clothing, hearing protection, hardhats and boots;
Make sure operator has seen you when working near moving plant and;
Trench digging works
Make sure no workers enter an unsupported section of trench or carry out any trenching work without supervision.
Use the correct tool for the task and train workers in it’s correct use;
Check tools are in good working condition;
Make sure that trenching supports are appropriate to the site conditions.
Make sure safe ladder access is available for all workers.
Ensure spoil heaps are positioned at least 900mm away from the trench.
Make sure at least 2 workers are present on site at all times during the work activity in case of emergency.
Use of backhoe for Excavation / Trenching
Make sure operator has the appropriate certificates or experience to operate the equipment;
Ensure the equipment is in good working condition and regularly maintained;
Check with Site Supervisor to identify details of underground services
Arrange for a worker to act as a spotter and maintain a safe distance from the machine;
Spotter to make sure the operator can seen you when working near moving plant and is to wear high visibility clothing, hearing protection, hardhats and boots;
The backhoe operator is to be aware of spotter’s location at all times and maintain a safe distance.
Hand excavate using a shovel to locate services at approximate location.
Make sure excavations and trenches are battered or benched if they are deeper than 1.5m.
Ensure that excavated materials are stockpiled at least 2m away from the excavation work area.
