In this episode of Developing WA, Kai Armstrong sits down with Russell to dive into all things forensics. Russell doesn't just design hydraulic systems, he gets called in as an expert witness when they fail and somebody ends up in court, usually by a lawyer acting for their client or a loss adjuster at an insurance company.

You'll hear why roof plumbing is no longer a licensed trade in WA, who actually carries the blame when a building fails and who walks away clean, and the dispute where both sides spent $800,000 each on legal fees to argue about a $600,000 repair.

Who's Actually to Blame When a Building Fails

In this episode of Developing WA, we’ve pulled together some of our best conversations so far. Kai Armstrong and Russell Green of OTG Hydraulic Consulting dig into what WA’s building boom is hiding and what happens when a building fails, and Russell sits down with Vadim Boyko of PROEKT to talk about why apartments are still a hard sell in Perth.

You’ll hear about the $250,000 claim that started with a failed box gutter on a high-rise in Scarborough, why Vadim reckons Perth is allergic to apartments, and the hot water pipe Russell says he’d run from if he were buying an apartment in Perth.

Best of Developing WA: Leaks, Blame and Perth’s Apartment Problem

In this episode of Developing WA, Kai and Russell go through the 2025 AS 3500 changes and what they actually mean on site. Parts one, two and four have been mandatory in WA since 1 May 2026, and Russell walks through the ones people are most likely to get caught by.

You'll hear what the new flexible hose classes mean for the flexi sitting under your sink, why a waterless urinal can now need a flushing device fitted to it, and why stormwater is the only unregulated section of AS 3500 in WA — the section behind 95% of the disputes Russell gets called into.

The waterless urinal that now needs a flush

In today's episode, Kai joins Russell to talk about what WA's building boom is doing to construction quality.

You'll hear why WA's shift to desalinated water is quietly wearing out plastic pipes years before they should fail, why the code covering box gutters and storm water is the one chapter of the plumbing standard nobody actually regulates, and why Russell thinks the industry needs to slow down instead of racing every project to 100 percent.
