隨著公共工程規模擴大與技術要求提升，監造技術服務廠商在品質管理與技術支援中扮演關鍵角色，近年因物價逐年上漲導致平均薪資連帶持續上漲，其監造服務的服務範圍及勞務成本顯著增加，特別是軌道工程等具有工程時間長且高風險的專案。然而，現行監造技術服務費未於契約訂定薪資指數調整機制及超出契約範圍之處理原則，未能反映實際投入與風險，導致廠商面臨利潤壓縮、優質廠商參與大型公共工程意願降低等問題，進而間接影響工程品質。鑑於此，本研究以國內公共工程為對象，針對現行監造技術費用編列及計價方式進行探討，並歸納於三項核心問題：(一)薪資指數調整機制不明確，致使契約未能合理反映人力成本變動；(二)契約範圍外追加配合工作之計費原則缺乏明確規定，導致廠商可能承擔額外風險；(三)計費基準未依工程類型差異進行調整，對於特殊工程之合理利潤較低。為解決上述問題，本研究透過文獻回顧、案例試算與專家訪談，提出三項具體建議：(一)制定明確且簡化之薪資調整公式、(二)建立超出契約範圍工作之處理原則，以及(三)針對特殊工程類型建議採「工程特性基數」進行計費調整。研究成果有助於提升契約公平性與預算編列合理性，進而促進監造技術服務廠商參與意願與提升公共工程之品質。;With the increasing scale and technical complexity of public infrastructure projects, construction supervision service providers play a critical role in quality management and technical support. In recent years, rising prices and wages have significantly expanded the scope and labor costs of supervision services, particularly in long-term, high-risk projects such as railway projects. However, current payment mechanisms for supervision services often lack provisions for salary index adjustment and compensation for work beyond the original contract scope. These limitations result in a misalignment between service fees and actual labor input and risk, leading to profit decreases and reduced willingness of high-quality firms to participate in large-scale public infrastructure projects, thereby indirectly affecting project quality. This study examines the budgeting and payment practices of construction supervision services in Taiwan’s public sector, and identifies three core issues: (1) the absence of a clear salary index adjustment mechanism, which prevents contracts from reasonably reflecting changes in labor costs; (2) a lack of explicit billing approaches for additional services outside the contract scope, exposing contractors to uncompensated risks; and (3) a failure to differentiate pricing standards based on project type, leading to insufficient profit margins in specialized projects. To address these issues, this study conducts a literature review, case-based cost simulations, and expert interviews to propose three practical recommendations: establishing a clear and simplified salary adjustment formula, defining compensation principles for out-of-scope tasks, and introducing a “project-type adjustment factor” for calculating fees in specialized infrastructure projects. The outcomes of this study aim to enhance contract fairness and budgeting rationality, thereby increasing the willingness of supervision service providers to participate and ultimately improving the quality of public infrastructure projects.
