Starting a structural engineering consultancy in Australia is not for the faint-hearted. You're competing against established firms with decades of templates, proven workflows, and junior staff to absorb the repetitive work. You have none of that. What you have is expertise, ambition, and a billing rate that can't yet justify burning three hours on a purlin check for a shed in Dubbo.
This is exactly the gap PurlinIQ was built to close.
The problem nobody talks about in engineering startups
When engineers go out on their own, the first thing they discover is that the bottleneck isn't winning work — it's doing it fast enough to be profitable. Industrial and commercial projects almost always involve purlin and girt design. It's routine work, but under AS/NZS 4600:2018 and AS/NZS 1170.2, it's far from simple.
Doing it properly — local pressure zones applied as moving loads, lapped zones modelled with correct stiffness, deflection checks across multiple serviceability envelopes — can take a solo practitioner the better part of a day if they're working from spreadsheets or doing it manually. At $150–$200 per hour, that's a $1,000–$1,600 task that the market prices at a fraction of that.
For an established firm, that cost gets absorbed across a team. For a startup, it comes straight off your margin.
What changes with PurlinIQ
PurlinIQ automates the parts of purlin design that are complex to set up but straightforward once the process is correct: wind load generation per AS/NZS 1170.2, continuous beam analysis with lapped zones properly modelled, code-compliant capacity checks against Lysaght, Stramit, and Stratco section libraries, and a complete exportable design report ready for submission.
A check that previously took two to three hours can be completed in under thirty minutes.
For a startup billing twenty purlin jobs per month — a realistic load for a solo practitioner winning shed and warehouse work in a regional or suburban market — that's the difference between forty hours of purlin work per month and ten. Those thirty hours don't disappear. They go into winning the next project, doing the structural work that actually requires judgement, or simply not working weekends.
The credibility problem, solved
New firms face a credibility gap that takes years to close through experience alone. Clients and certifiers are cautious about reports from practices they don't know.
PurlinIQ's outputs are validated against ColdSteel, the University of Sydney's recognised benchmark software for cold-formed steel design. Every design report shows the load cases applied, the combinations considered, the analysis model used, and the capacity checks performed — referenced directly to the relevant clauses of AS/NZS 4600:2018.
That level of documentation is what peer reviewers and certifiers expect from large firms. PurlinIQ puts it in the hands of a one-person practice from the first project.
What the numbers look like for a solo practice
Illustrative scenario — not a real customer
Take a solo structural engineer who has left a mid-sized consultancy to start her own practice, winning steady work designing industrial sheds and farm buildings across regional NSW. Purlin design is the most time-consuming repetitive task in her workflow. On the timings above, switching to PurlinIQ would mean:
- Average time per purlin job dropping from 2.5 hours to 40 minutes
- Roughly 25 billable hours per month recovered
- Design reports that are more consistent and more detailed, without extra time spent producing them
At that volume, the subscription costs less per month than the revenue from a single hour of recovered time.
The figures above are modelled, not measured — they follow arithmetically from the per-job timings, applied to a typical solo workload. Your own mileage depends on job mix and how much of your current time goes to setup rather than judgement.
Why this matters more for startups than anyone
Established firms have process. They have templates refined over years, junior engineers who run the spreadsheets while seniors check the results, and clients who return out of habit. Startups have none of that institutional infrastructure.
What they do have is the ability to move fast — to adopt tools that incumbents are too slow or too comfortable to change. PurlinIQ gives a new practice the same quality of output as firms ten times its size, without the overhead that makes those firms slow.
For a market that wants fast turnarounds with defensible documentation, that's not a minor advantage. It's the difference between being competitive from day one and spending your first two years grinding through work that pays less than your time is worth.
Getting started
PurlinIQ is cloud-based — there's nothing to install, no licence server to manage, and no IT overhead. A new practice can be running production-quality purlin designs within an afternoon of signing up.
If you're starting a structural engineering practice, or you're an established sole trader looking to reclaim time on routine work, PurlinIQ is worth a look.
PurlinIQ is developed and maintained in accordance with AS/NZS 4600:2018, AS/NZS 1170.0, and AS/NZS 1170.2. Section libraries cover Z and C sections from Lysaght, Stramit, and Stratco.

Running a business takes a lot of moving pieces and parts. Getting all these elements to work in tandem is what helps – or hinders – your objectives.

Purlin design was a rite of passage: slow, fiddly, and expected to be. A structural engineer on where the hours actually went, and why speed turns out to be a risk control rather than a convenience.
