Screw Pile Services – Consultation, Supply, Approvals & Installation
We provide end-to-end screw pile solutions for residential, commercial and infrastructure projects—covering site consultation, engineered specification, premium supply, safety approvals, installation and certification. Our approach prioritises structural performance, compliance with Australian Standards, and a clean, efficient install that keeps your program moving.
What We Do
Consultation & Design Input. We review drawings and soil information (or help organise a geotechnical investigation) and recommend pile types, diameters, helix configurations and design capacities aligned with AS 2159 (Piling — Design & Installation). Where required, we coordinate a structural engineer to provide signed calculations and certificates.
Supply. We source high-quality, Australian-certified steel screw piles and accessories manufactured to suit your loads and site conditions, with traceable mill certificates and weld procedures in line with AS 4100 (Steel Structures).
Approvals & Safety. We assist with the documentation councils and building surveyors typically require—geotech reports, engineering drawings, installation methodology, OH&S plans and testing records—coordinated to the National Construction Code (NCC/BCA) and relevant state requirements.
Installation & Verification. Our trained operators install with calibrated torque monitoring to confirm capacity in-situ, followed by proof/load testing as specified in AS 2159. On completion, you receive installation logs and an engineer’s Certificate of Compliance for handover.
Why Screw Piles?
Fast & clean. Minimal spoil, low vibration and immediate load-readiness mean other trades can proceed without curing delays.
Versatile. Reliable in variable soils, reactive clays, high water tables and tight-access sites. Ideal for boardwalks, decks, modular buildings, house restumping/underpinning, and commercial footings.
Lower impact. Reduced site disturbance and ease of de-installation support sustainability aims and sensitive environments.
Our Process
- Scope & desktop review: plans, loads, access and utilities (including Before You Dig Australia utility checks).
- Geotech & engineering: soil investigation (if needed) and engineered specification/capacities.
- Approvals pack: NCC/BCA-aligned method statements, SWMS, and documentation for your building permit.
- Install & records: calibrated torque install, verification testing and as-built reporting.
- Certification & handover: engineer sign-off, test results and compliance artefacts ready for surveyor/council.
Typical Documents We Provide
Geotechnical report (where applicable), engineered drawings & calculations, SWMS and OH&S plan, installation torque logs, proof/load test results, material certificates, and an engineer’s Certificate of Compliance.
Safety, Compliance & Licensing
We operate to the standards, codes and licensing frameworks that apply to screw piling in Australia. Requirements can vary by state/territory and project scope; the links below point you to the primary references and regulators.
Core Technical Standards & Codes
- National Construction Code (NCC / BCA) — overarching building performance and compliance framework.
- AS 2159 — Piling: Design & Installation — design actions, installation, verification and testing for piles (including screw piles).
- AS 4100 — Steel Structures — materials, fabrication and structural steel requirements.
- (Project-specific) Earthworks/retaining references such as AS 4678 — Earth-Retaining Structures where relevant to the design.
Work Health & Safety (WHS)
- Safe Work Australia — Construction Work — model WHS guidance for plant, high-risk construction work, and SWMS.
- State regulators (examples): WorkSafe Victoria, WorkSafe Queensland.
- Utility services location: Before You Dig Australia (BYDA) — mandatory asset location enquiries prior to ground penetration.
Licensing & Practitioner Registration
Exact licence classes differ across states. Always confirm the appropriate builder/contractor class for “piling/deep foundation work” with your local regulator and ensure a registered professional engineer signs the design and as-installed certification.
- VBA (Victoria) — Building practitioner registration and building permit framework.
- QBCC (Queensland) — Contractor licensing; check the class that covers piling/deep foundation works.
- National training competency (operators): RIICFW308 — Conduct screw piling operations (and related units as applicable).
Engineering Certification & Testing
Designs and as-built installations should be certified by a suitably qualified, registered engineer. Verification methods typically include torque correlation and/or proof/load testing in accordance with AS 2159, with results issued in the final compliance pack.
FAQs
Do screw piles work in reactive or saturated soils?
Yes—helical pile geometry can be engineered for expansive clays and high water tables. Final capacities are set by your geotechnical conditions and verified during installation by torque and/or load testing.
Can you install in tight access areas?
We use compact, high-torque equipment and modular shafts/segments, enabling installs in constrained sites with minimal disturbance.
What will council/building surveyors ask for?
Typically: geotechnical report (if needed), engineered design, SWMS/OH&S plan, installation torque logs, proof/load testing (where specified), and an engineer’s Certificate of Compliance—aligned to the NCC/BCA and AS 2159.
