Do you provide structural certification?

We design the system and coordinate with a suitably qualified structural engineer for sign-off where required.

Can you work from drawings only?

Yes—early-stage concept design can be done from plans/sections; we’ll validate on site before construction.

Are your specs tied to one brand?

No. We write product-agnostic specs and will list acceptable systems where helpful.

Can you supervise installation?

We offer tender support and site inspections/hold points to ensure installation matches the design intent.

What standards do you align with?

AS 1657, AS/NZS 1891 series, AS/NZS 5532 (anchors), and the NCC—plus manufacturer requirements.

Consulting & Design Review

Make compliance simple—and safe from day one.

PRO HEIGHT provides independent consulting and practical system design for roof access and fall protection across Perth and WA. We align solutions to AS 1657 (walkways, guardrails, stairs & ladders) and AS/NZS 1891 (fall-arrest systems), with consideration of AS/NZS 5532 (single-point anchors) and the NCC. You’ll get clear advice, buildable drawings and a step-by-step plan to install or upgrade with minimal disruption.

Compliance audits of existing roofs and access paths
Concept & detailed design for anchors, static lines, walkways, ladders, guardrails, platforms and access hatches
Load path & substrate recommendations (coordinating structural sign-off where required)
Product-agnostic specifications and bill of quantities for tender
Scope & staging plans for live sites and multi-building portfolios
As-built verification and handover documentation
Lifecycle planning: inspection regimes, registers and maintenance intervals

Hazard hierarchy – Prioritise elimination and passive protection; fall-arrest only where necessary.
Concept options & budget – Side-by-side options with pros/cons and budget ranges.
Detailed design package – Plans/elevations, typical details, fixings, penetrations and interfaces.
