Abstract

In Japanese steel fabricators, significant time is devoted to drafting fabrication drawings compared to the fabrication process itself, highlighting a need for efficiency improvements. A primary issue is the inadequate consideration of constructability at the design stage. Steel fabricators often sign contracts based on partially completed designs, leading to frequent modifications from the creation of fabrication drawings up until just before fabrication begins, which hampers productivity improvements. To address this challenge, this study proposes separating and contracting engineering from fabrication early in the design phase through front-loading detailed design. If front-loading is feasible, it could reduce the frequency of changes and corrections, improving the drawing process and potentially enhancing efficiency in steel fabricators. Furthermore, the study explores what constitutes feasible engineering for front-loading, considering that steel fabrication involves aspects beyond mere structural design.
