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

Working prototype

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.

Real output · fictional inspection notes
  • 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.
Working prototype

Meeting Minutes Builder

Turns a raw safety-meeting transcript into structured minutes: decisions, owners, deadlines and follow-ups from last meeting.

Real output · fictional transcript
  • 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
In use

Safety Notice Writer

Drafts clear, short safety notices and reminders for site group chats from a few bullet points — typhoon preparation, deadlines, incident lessons.

Real output (condensed) · fictional request
  • 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。

Daily Safety Incident Digest Running daily since Sep 2026

An automated pipeline that reads public incident news every day, analyses each accident with Claude, checks every cited regulation against the official law text, and produces a two-part toolbox-talk poster: what happened, and how to prevent it.

Public news & OSHA notices→Claude: group, verify, root causes, prevention→Regulation citations hard-checked against law database→Two-part poster + text check→Review queue

Fall from height — worker removing an external work platform

Hong Kong construction site · Oct 7, 2026 · 1 fatality · source: HK01 news report

Poster 1 of 2: sequence of the fall, steps 1 to 4
1/2 · What happened (steps ①–④)
Poster 2 of 2: matching prevention measures 1 to 4
2/2 · Prevention, matched to each step
  • Cause (Claude analysis): harness worn but lanyard not clipped to an anchor; lost balance stepping onto the outer platform.
  • Cited regulations: Construction Safety Standards Art. 17, 19, 23; OSH Facilities Rules Art. 281 — all verified against the official text.

Struck by a road roller during resurfacing

Road works, Vietnam · Oct 2, 2026 · 1 fatality · source: news report

Poster 1 of 2: worker in the path of an operating road roller
1/2 · What happened
Poster 2 of 2: exclusion zone, spotter, high-visibility clothing
2/2 · Prevention: exclusion zone, spotter, clear-before-rolling
  • Cause (Claude analysis): worker cleaning inside the roller's travel path; driver did not see the worker (inferred).
  • Cited regulations: OSH Facilities Rules Art. 116, 21-1, 21-2 — verified.

Facts come from the linked public news reports; steps marked “inferred” (研判) are the model's reasoning, not official findings. Analysis and poster text are written by Claude; poster illustrations are rendered by a separate image model. Posters are in Traditional Chinese for Taiwanese site crews.

Real outputs

Screenshots of unedited Claude API output from our prototypes, run on fictional inputs (Oct 8, 2026).

Meeting Minutes Builder output: decisions, action items with owners and due dates, carried-over items
Meeting Minutes Builder — a messy transcript becomes decisions, owners and deadlines.
Hazard check output: hazard, applicable regulations with verify flags, corrective actions
Hazard Check — each hazard mapped to regulations; uncertain article numbers are flagged “verify” instead of guessed.
Safety Notice Writer output: warns that locking tower-crane slewing in a typhoon is unsafe, then writes the notice
Safety Notice Writer — the request said “lock tower-crane slewing”; the tool flagged it as unsafe before writing the notice.
