AI tools that help construction sites stay safe and compliant.
Chuan Works turns the paperwork of site safety — photo inspections, regulation lookups, meeting minutes and safety notices — into minutes of review instead of hours of typing. Built by a construction-safety practitioner, for the people who do the work on site.
Tools in development
Site Photo Hazard Check
Upload a site photo; get a hazard checklist mapped to the relevant articles of Taiwan's Occupational Safety and Health regulations.
- Unanchored harness at 3 m edge — 營造安全衛生設施標準 第19條 (openings & edges ≥ 2 m need guardrails, covers or nets). Action: stop work, install guardrails or a rated anchorage, 100% tie-off.
- Uncovered 1 m floor opening — same article; barricade now, secured and marked cover the same day.
- Articles it is unsure of are marked “verify” instead of guessed.
Meeting Minutes Builder
Turns a raw safety-meeting transcript into structured minutes: decisions, owners, deadlines and follow-ups from last meeting.
- Decision: toolbox talks move to 07:45 from Monday, with attendance taken
- Action: submit lifting plan for Friday crane lift — Sub A — Thu 12:00
- Carried over: level-3 guardrail, reported last week, now due Wed
Safety Notice Writer
Drafts clear, short safety notices and reminders for site group chats from a few bullet points — typhoon preparation, deadlines, incident lessons.
- The request asked to “lock tower-crane slewing”. The tool flagged that this is unsafe in a typhoon — the slewing brake should be released so the jib weathervanes — and wrote the notice accordingly.
- 【颱風安全通知】今日 17:00 前完成：綁紮鬆散物料、加固安全網、塔吊吊鉤升至最高並鬆開迴轉剎車、清理排水。完成後拍照回覆。
How we use Claude
- Claude API (vision) — reads site photos and matches what it sees to specific safety regulations.
- Claude API (long documents) — drafts safety plans, meeting minutes and notices from transcripts and notes.
- Claude Code — builds and maintains the web apps behind these tools.
- Claude Team — shared workspace for a small group of practitioners testing the tools.
