Driven Pile Installation (Precast)

Precast concrete piles are manufactured off site and driven into the ground using impact or vibratory hammers.
Piles can be up to 20 metres long and weigh several tonnes, requiring crane lifts for positioning.
Impact driving generates extreme noise levels exceeding 100 dB at the operator position.
Vibration from pile driving can affect adjacent structures, requiring pre-condition surveys and monitoring.
The pile head must be protected with a helmet and dolly to prevent damage during driving.
Broken or damaged piles during driving can eject concrete fragments at high velocity.
Pile pitching — lifting and guiding the pile into the leader — is a critical high-risk lifting operation.
Buried services must be cleared from the pile location before driving begins.
Ground heave from displacement piling can affect adjacent piles and nearby structures.
All piling operatives must hold CPCS or NPORS certification for the specific rig category.

Noise exposure	Impact pile driving generates extreme noise that causes permanent hearing loss without mandatory hearing protection.
Lifting hazard	Long, heavy precast piles require precise crane lifts — a dropped or swinging pile can be fatal.
Vibration damage	Pile driving vibration can crack adjacent buildings, damage services, and disturb neighbours.

Do

Don't

Wear double hearing protection (plugs and muffs) during impact pile driving operations
Prepare a lift plan for pitching each pile into the leader with the crane
Install vibration monitors on adjacent structures before pile driving commences
Inspect each pile for cracks, damage, and correct reinforcement before pitching
Maintain an exclusion zone around the piling rig during driving operations
Clear buried services from each pile position using the permit to dig system
Protect the pile head with the correct helmet and dolly to prevent concrete spalling
Monitor pile set and driving resistance to confirm design capacity is being achieved
Brief the piling crew on the pile schedule, sequence, and adjacent structure risks
Record driving logs including blow counts, set, and any refusal or damage incidents

DON'T stand within the exclusion zone during pile driving operations
DON'T pitch or handle piles without a crane lift plan and trained slinger
DON'T drive piles without hearing protection — noise levels cause instant damage
DON'T continue driving a pile showing signs of cracking, spalling, or deviation
DON'T drive piles without vibration monitoring where adjacent structures are at risk
DON'T allow pile driving over uncleared buried services
DON'T use a damaged pile helmet or dolly — replace before driving resumes
DON'T ignore ground heave readings affecting previously installed adjacent piles
DON'T allow untrained or uncertified operatives to operate the piling rig
DON'T start driving without confirming the pile type, length, and toe level are correct
