Every Calculation.
One Workspace.

OZR Labs calculators are built to Australian Standards including AS 1170.1, AS 1170.2, AS 1170.3 (loading), AS 3600 (concrete structures), AS 4100 (steel structures), AS 2159 (piling), AS 4678 (earth retaining), AS 2870 (residential slabs), AS 4600 (cold-formed steel), AS 1720.1 (timber), and AS 5216 (anchors). Every check is clause-referenced throughout.

No. OZR Labs is entirely browser-based. Open it on any device — Windows, Mac, iPad, or Linux — and all calculators run natively in your browser. No plugins, no desktop installs, no version management. Your data is saved to your account automatically.

Yes. Your account syncs across all devices. Sign in from the office, from a tablet on site, or from your laptop at home — all your saved projects are accessible from anywhere.

Solo ($15/month) gives you access to one calculator of your choice from the live suite — excluding Wind Site Analyzer and Pad Footing Designer, which require Individual or above. Individual ($39/month) unlocks all live calculators including Wind Analyzer and all Pad Footing modes, making it the best value for sole practitioners. Professional ($69/month) adds firm branding on PDF reports, 2 included seats (expandable to 5), full project version history, and priority email support — built for small engineering firms.

OZR Labs generates clause-referenced PDF calculation sheets documenting all inputs, assumptions, intermediate results, and final checks. These are designed to be peer-review and submission-ready. Final engineering responsibility remains with the reviewing RPEQ or equivalent who signs off the calculations.

Yes. Plans can be cancelled or changed at any time from your account settings. Monthly plans cancel at the end of the current billing period. Annual plans are non-refundable but can be downgraded at renewal. No lock-in contracts.
