工程品質之提升，為國內經常性之議題，尤其是公共工程施工品質，最為社會大眾關切，而工程品質之關鍵，在於工程之設計與規劃、工程之管理、施工之品質及材料之品質，因此工程材料之檢驗實為工程品質之重要環節，而材料品質之檢驗，即與工程材料之測試實驗室有關。行政院公共工程委員會及大多數工程單位指定並接受TAF認可實驗室出具之報告，但因部分認可實驗室之報告品質受到質疑，造成TAF之認證公信力受到影響；行政院公共工程委員會並進一步要求TAF加強認證實驗室之監督與管理。 因此，本研究將針對國際符合性評鑑機制/架構/標準、TAF之認證作業/規範/發展狀況及國內施工品質管理制度進行瞭解，探討TAF土木工程測試領域實驗室認證現況及實驗室經營管理問題，並提供回饋性建議，期能提升認證公信力，使各界均能了解並接受符合性評鑑機制及認證，進一步促進國內工程品質之實質提升。 The enhancement of the construction work quality, particularly the public ones, has become a current issue and drawn lots of the public’s attention. The key to the public construction quality lies in the design, planning and management of construction works, as well as the quality of construction execution and construction materials. Thus, the test results of construction materials, issued by testing laboratories for construction materials, are crucial to the construction quality. The PCC and most construction related government sectors request for and accept construction materials test reports issued by TAF accredited testing laboratories. However, some doubtful test reports, issued by TAF accredited laboratories, have caused adverse impact on TAF accreditation credibility. For this reason, the PCC has also been continuously requesting TAF for monitoring and management of its accredited laboratories. This study focuses on the current status and the business managerial aspect of TAF accredited civil engineering testing laboratories. It looks into the international conformity assessment mechanism / structure / criteria and TAF procedures / criteria / development. Feedbacks and comments are also provided for the purpose of promoting the accreditation credibility. The goal is to make conformity assessment mechanism and accreditation been recognized and accepted; and eventually facilitate the substantial enhancement of construction quality.
