臺灣位處地震帶及溫暖潮濕海島型氣候,導致建築物滲水問題層出不窮,因此尋求建築物防水施工流程之失效模式並建立預防機制為防水工程極為重要課題。本研究以L防水工程公司為例,探討防水工程之失效模式與效應分析 (Failure Mode and Effects Analysis,簡稱FMEA),希望透過 FMEA 的系統性分析工具,達成防水施工作業客觀評量,讓防水施工作業有評估標準,以提供防水工程施工流程一套客觀參考標準。 本研究首先,針對防水工程施工前、施工中及施工後之作業流程加以分析,提出18項潛在失效模式;其次,經由專家意見調查來評定每一項潛在失效模式之嚴重度、發生度及難檢度;然後,經由計算風險優先指數,並考量嚴重度等級高於9之潛在失效模式,據此確認風險性較高之失效模式;最後,針對這些中高風險之潛在失效模式,提出預防性措施以及萬一失效發生之補救方式的建議,以提供給L工程公司及防水工程業者之管理參考。 研究結果發現,FMEA手法運用在防水工程施工中4項高風險之失效模式中可能發生並造成高嚴重度失效模式中需立即改善,6項中風險之失效模式中需採取行動預防可能發生失效模式及依RPN值高低前3項低風險執行改善措施,對防水工程施工要項進行風險評估,提出改善優先順序,以利研擬相關對策,已達到預防之目的。 It's led to such problem of building seepage that Taiwan is located on seismic zone and marine tropical climate area. It's becoming one of the most important subjects of construction waterproofing to find out failure mode and effects analysis (thereafter referred to as FMEA) and prevention. The study is exploring FMEA of waterproofing construction on basis of an example of L Waterproofing Construction Company, and creating construction process and evaluation standard of waterproof. This study firstly analyzed working process of waterproofing construction and induced 18 potential failure modes. Secondly, the risk priority number (RPN) of each failure mode was calculated in accordance with evaluating severity, occurrence, and detection of each item. Based on the RPN and severity of 9, the action criteria were set up for further FMEA analysis. Finally, the rescue and prevention plan were come out in terms of those middle and high risky level of failure modes. The research result will be recommended to L Waterproofing Construction Company as reference of management. The study found there are 4 items in high risk causing severe failure need to be improved immediately. There are 6 items in middle risk have to take action to prevent possible occurrence of failure mode and prioritize top 3 in view of RPN value for implementing actions, and risk assessment for achieving avoidance of failure. |
