Investigation and Documentation: Measure Before You Move

A scene of on-site investigation. Personnel are setting up a laser scanner and cameras under the roof truss, grid markers are affixed to the walls, and they hold as-built drawings and annotated damage locations. Old photos and drawings from previous years are spread on the ground for comparison. No demolition work has begun yet. Avoid: directly entering the construction phase, having no drawings or measurement tools on site, replacing actual measurements with baseless imagination, depicting the investigation as a supplementary record after construction has already started.

一個現場調查的畫面。人員在屋架下架著雷射掃描儀與相機,牆上貼著網格標記,手上是現況實測圖與損壞位置的標註;地面攤開歷年的老照片與圖面做比對。還沒有任何拆除動作。避免:直接進入施工階段、現場沒有任何圖面與量測工具、用憑空想像取代實測、把調查畫成已經動工後的補記錄。
