摘要

當既有空間不敷使用或開發計畫分期執行時，常需於既有基地進行增建工程。由於進行此類工程時，一方面需維持既有建築物之使用功能；另一方面又必須兼顧既有與增建工程施工安全性，故規劃時往往捉襟見肘。另外，當建物老舊時，也常需於原工址進行改建工程。由於國內工程界缺乏相關施工案例，因此工程往往僅能採土法煉鋼方式進行，缺乏完整之施工規劃，故希望藉由實際案例，來探討此一棘手問題。本文主要提供增建與改建工程實際成功案例，以供往後類似工程之參考。

It is often necessary to call for Expansion Engineering of the existing buildings when the existing building space is insufficient for usage or when staged development is implemented. However the planning of Expansion Engineering is more difficult than other engineering works. Because not only the original functionality of the buildings must be maintained, but the safety of construction must be included into consideration as well. In particular, if the original buildings were aged and reconstruction work must be conducted on the same site. Due to the shortage of case studies, domestic contractors usually rely heavily on experiences and therefore lack proper planning in dealing with expansion/reconstruction engineering work. It is our sincere hope that by providing the actual and successful expansion/reconstruction work, we can explore this issue and provide further reference for later work.
