Workflow

inferred: 중소 건설사 안전관리자 — 공식 기상 특보·현장 온도·휴식시간을 매일 대조하고 작업중지 근거를 기록

Problem

Safety managers at small construction and landscaping companies must separately retain official weather information, on-site measurements, and worker break records during extreme heat or rainfall. If an accident or schedule-delay dispute occurs, presenting the basis for a work-stoppage decision at a specific time can be difficult.

Solution

The service combines site location, official weather alerts, and mobile check-ins to create a timeline of work stoppages, breaks, and resumptions, with evidence suitable for submission to the contracting organization. As site decisions and actual work outcomes accumulate, the data supports operating criteria by work type and identifies recurring high-risk time periods.
