Trenchless & Pipe Relining SWMS Templates

Yes. CIPP relining typically engages two HRCW categories under WHS Regulation 2025 Schedule 1, clause 291: work in or near a confined space (host pipe, launch pit, manhole) and use of hazardous chemicals (styrene-based or epoxy resins). A SWMS is mandatory before work starts and must address atmospheric monitoring, ventilation during steam and UV cure, SDS-driven PPE selection, and emergency retrieval. The model Code of Practice: Confined Spaces and the Hazardous Chemicals Code both apply.

If workers enter the manhole, pit or host pipe, yes — a confined space entry permit is required under WHS Regulation 2025 Part 4.3, regardless of work duration. AS 2865 governs safe entry procedures, including atmospheric testing for oxygen, LEL, H2S and CO before and during entry. Where relining is completed entirely from the surface via robotic cutters and remote inversion, confined space duties may not trigger, but adjacent manholes used for liner access usually still require permits.

A SWMS is a legally required document under WHS Regulation 2025 for any HRCW activity, with prescribed content: hazards, controls, how controls are implemented, monitored and reviewed. A JSA (Job Safety Analysis) is a broader risk tool with no statutory format. HDD frac-out, pipe bursting near services, and hot-tapping all involve HRCW triggers (energised services, pressure, confined spaces), so a compliant SWMS — not just a JSA — must be prepared, signed by workers, and available on site.

Yes. Hot-tapping potable or raw water mains is controlled under AS/NZS 3500 and water authority technical specifications, focusing on contamination, pressure containment and isolation. Hot-tapping gas or hydrocarbon pipelines falls under AS 2885.2 and requires qualified pipeline welders, a documented hot-tap procedure, fitness-for-service assessment of the host pipe, and engineering sign-off. SWMS content for gas hot-taps must reference ignition control, gas detection, and emergency shutdown — controls not typically required for water applications.

The core SWMS content is harmonised because WHS Regulation 2025 applies in all jurisdictions except Victoria (OHS Regulations 2017) and WA (WHS Regulations 2022, which mirror the model). What changes is referenced authority — Dial Before You Dig (now BYDA), state water authority technical standards, and local council trade waste conditions. Templates should remain regulation-anchored and project-customised: site address, supervisor, plant, services located, and permit references added per job rather than per state.
