Design & analysis toolkit
The complete calculation library, organised like Tekla Tedds and GEO5: steel, concrete, timber and masonry design, foundations, retaining walls and slopes, ground engineering, site investigation, pavements and traffic, hydraulics, bridges, and analysis and loading. Each calculation runs in your browser, shows its formulas, pass/fail checks and a drawing with standard engineering hatching that redraws as you type, and exports a live-formula Excel workbook.
Disclaimer: for preliminary and educational checks only. These are not certified designs. Results follow Australian Standards conventions (AS 3600, AS 4100, AS 2159, AS 2870, AS/NZS 1170, AS 1170.4, AS 1720, AS 3700, AS 4055, AS 5100, AS 4678, AS 1289, AS/NZS 1170.2 and 1170.3, QUDM, ARR 2019, Austroads) and published methods (FHWA, BS 8081) with simplifying assumptions stated in each tool. Check against the current standard and have a qualified engineer review before use.
