This method is suitable for shafts generally larger than bored shafts. The shaft remains fully supported and lined for its entire length. Caissons may be pressurised in certain circumstances with compressed air to provide temporary ground support and reduce water entry at the shaft bottom. Control measures should be implemented to eliminate or minimise, so far as is reasonably practicable, the risks associated with caissons. The Guide Tunnelling (Australia): Specific Hazards, Risks and Control Measures – Caissons mobile app cover specific hazards, risks and control measures for caissons.

“I’m not a tech guy and I was able to pick this thing up in probably an hour, and actually start to build apps. I’ve done them over lunch when I’ve gotten frustrated with a process that didn’t exist in our company. So for non tech people who’ve got a problem, the support here is awesome and I’d recommend it to anybody, not just in our industry.”
