目前縣市政府進行橋梁之管養皆以「公路養護規範」為依據，其中規定公路橋梁至少兩年檢測一次。現行檢測方式多以目視檢測法為主，併以非破壞性檢測為輔。根據統計，縣市政府轄下約有1萬8千餘座橋梁，但檢測作業之詳實度尚有不足。 本研究以縣市政府橋梁檢測契約與執行方式為探討核心，蒐整近三年共20份縣市政府橋梁檢測契約，並訪談橋管機關承辦人員及檢測作業執行廠商以了解橋梁檢測執行現況，彙整出影響橋梁檢測費用最大的三個因子為（1）是否使用特殊工具，（2）橋梁總數，與（3）橋版面積；影響檢測工期最大的四個因子則為（1）橋梁劣化程度，（2）天候，（3）橋梁地域，以及（4）是否使用特殊檢測工具。本研究並對橋梁檢測發包方式，以及承辦人員教育訓練不足提出改善之建議。最後，為避免檢測不實之情況產生，本研究探討橋梁檢測作業三級品管辦法，透過查核之方式以確保橋梁檢測結果之品質，以提升國內橋梁維護管理水準。 “Road Maintenance Codes” provide the basis of bridge maintenance activities for County and City governments. The Codes regulate that bridges are to be inspected visually once per two years, accompanied by non-destructive inspections if necessary. Currently there are about 18,000 bridges governed by County and City agencies. However, it often can be found that the bridge inspection results are not professionally correct, and could be possibly due to unreasonable contract prices or duration. This research collected 20 contracts that were performed in the last three years and interviewed personnel who were related to or responsible for the inspection. Results of this research consist of two sets of influence factors for inspection costs and inspection duration, and suggestions to training and quality assurance mechanisms of bridge inspection. The top influence factors for inspection costs are (1) using of special inspection tools, (2) total number of bridges, and (3) total areas of bridges while the top influence factors for inspection duration are (1) degree of bridge deterioration, (2) weather, (3) location of bridges, and (4) using of special inspection tools. These results are expected to be useful references to the personnel who are concerned with the quality of bridge inspection.
