國內公共工程經常發生進度落後之狀況,進而導致延誤完工時間、逾期罰款等問題。為解決時程延遲可能問題,承包商通常向機關提出展延工期或趕工計畫,經由機關審核後同意承包商展延完工工期及進行趕工計畫。而實務上國內機關雖有展延工期及趕工計畫的表單及參考範本,但對於審查的項目無一標準協助機關審查廠商所提送展延及趕工計畫申請的佐證資料完整性及合理性,審查人員僅能依自身經驗做判斷。本研究蒐集國內外機關內部在展延工期及趕工計畫審查的程序規範資料,接著彙整不同機關針對審查流程及準則,並透過專家訪談進行歸納與檢核,建立可供國內機關在審查展延工期及趕工計畫審查作業參考之準則,以利機關審查人員在進行展延及趕工計畫審查作業時有明確的參考依循。;Public construction works commonly encounter the problem of falling behind schedule, and consequently result in delaying target project duration and occurring delay penalty. For dealing with the possible schedule delay problems, the contractor usually proposes the Extension of Time (EOT) and Construction Acceleration Plan (CAP) that require to be reviewed and approved by the client. Some government agencies have application forms and reference example for EOT and CAP; however, there is no standard review principle for checking the integrity and rationality of contractor’s submittals about EOT and CAP. In general, the reviewers conduct review works merely on their experience. This study collects the manuals and specifications about EOT and CAP in Taiwan’s governments and the literature, summarizes common procedures and key review items and principles, interviews with domain experts for issues identification and outcomes review, and finally proposes operation procedures and review principles for EOT and CAP. It is anticipated that the proposed operation procedures and review principles for EOT and CAP could be a valuable reference for the reviewer.
