Structural design tools that replace the spreadsheet.

Consistent, controlled calculators for the checks and design flows that practising structural engineers run, from desk to site. Developed for New Zealand design practice.

Why engineers leave spreadsheets

SpreadsheetsStruxCalc
Methods and limits need documenting alongside the formulas.Each tool states its calculation basis, scope and limitations.
Saved values can be mistaken for current results.Reopening a project recalculates its results from the saved design data.
Input checks depend on how each workbook is maintained.Tool-specific input checks and file validation are part of the workflow.
Layouts and report formatting vary between files.Project-file and report controls follow a shared workflow across the tools.
