Time on siteAbout 1 hour on site

Inspected againstAS 2870, AS 3600, the geotechnical report and the engineer's footing design

What is included in a Tarneit bored piers inspection

Pier positions and spacing against the footing plan
Pier diameter checked at the top of each hole
Depth against the engineer's design and the soil report
Founding material at the base where visible
Reinforcement cage size, laps and starter bars
Cover to the cage and centralisers
Hole cleanliness, spoil and loose material
Standing water or seepage before the pour
Steel projection into the slab or beam
Termite and service penetrations near piers
Set-out against the site plan and boundaries
Records and photographs for the engineer where required

Why it matters here

Bored piers inspections on Tarneit builds

Tarneit sits on reactive Werribee Plains clay over basalt. Where the soil report calls for piers, their depth and founding material carry the house. Once concrete is poured nothing here can be verified, and an undersized or shallow pier shows up years later as slab movement.

What we find at this stage in Tarneit

Pier depth short of the engineer's design
Cage not centralised, cover lost on one side
Loose spoil or water left in the hole
Pier positions out against the footing plan
Starter bars too short for the beam above

FAQ

Bored piers inspections in Tarneit: common questions

Does every Tarneit build have bored piers?

No. It depends on the soil report and the engineer's footing design. Many Tarneit lots are a stiffened raft with no piers, while deeper fill or reactive sites call for piers or screw piles.

How do I know if my build needs a pier inspection?

Check the engineering drawings for pier or pile schedules, or send us the plans and we will tell you.

What if piers are poured the same day they are drilled?

That is common, so timing matters. Tell us as soon as the footing date is set and we will attend between drilling and the pour.
