Can screw piles be installed close to an existing structure?

Yes, genuinely well suited to this — screw piles’ low-vibration, mechanically-screwed installation makes them a particularly good option for work close to existing structures, compared to methods involving more disruptive excavation or drilling.

This is exactly why screw piles are frequently chosen for extensions, additions, or structures near an existing building, where minimising disturbance to what’s already there genuinely matters.

Even so, proper assessment of the existing structure and appropriate clearance is still part of correct engineering practice — “low disruption” doesn’t mean no consideration is needed at all.
