Everything in one place
Hundreds of ready-to-use prompts for everyday engineering tasks — copy, tweak and paste into your AI of choice.
34 structural design checks for fast sense-checks — full working and a clear pass / fail.
Standards, methods and worked precedent, searchable and at your fingertips.
Steel, timber and concrete section data, materials and a glossary — the numbers you look up all day, built in.
Open and review IFC models for a quick look — no heavyweight BIM suite needed.
Redline drawings and spot the revisions between two issues, side by side.
Capture site photos and pull text straight off a scan or drawing.
To-dos, notes, registers and project records — keep the day's admin in one place.
No cloud and no account — your projects stay confidential on your device.
Put your practice's logo and accent colour on the app and every calc sheet.
Calculations
Every check shows its full working, the clauses it draws on, and a plain pass / fail verdict — then exports to a branded calc sheet ready for the file.

Reference at your fingertips
Steel, timber and concrete section properties, a materials library and a glossary — searchable and offline, so you're not digging through PDFs or the blue book mid-calc.


Drawings & documents
Redline a drawing with clouds, arrows, notes and stamps, then compare two revisions side by side to see exactly what changed — and OCR a scan when you need the text back.

For practices & teams
Ten minutes a day lost to chasing references, refinding downloads, working around cloud access, rebuilding calcs and marking up adds up to roughly a working week per person, every year. Engineers Digital Hub gives that local place on your machine, like a toolbox to assist with the task.
