近年來建築工程逐漸要求導入建築資訊建模（Building Information Modeling，BIM）技術，透過協同作業、減少衝突及變更設計的發生，進而提升工程效率與品質。現行國內編列BIM費用方式大多以工程費之百分比做為編列BIM預算參考值，此作法雖然可以推估費用，但實務上仍缺乏一致性參考百分比及明確之規定，且無法反應合理投入的人力及時間。本研究主要目的係分析國內建築工程運用BIM技術之費用編列問題，進而提出適用於國內建築工程以服務成本加公費法估算BIM費用之架構與步驟。本研究針對機關委託PCM、統包兩項工作，利用案例分析執行BIM技術所需之工作項目、投入人力與時間，同時輔以調查目前BIM人員薪資單價資訊，建立BIM預算編列完整程序，提出「機關應用BIM技術費用估算原則」，最後透過實際案例檢核與專家訪談以驗證其可行性與合理性。此外，本研究也針對直接相關的六項預算編列重要議題，進行討論，並提出看法與建議。期望本研究提出的BIM費用估算方式，將有助於日後機關在編列BIM預算時應用，以使廠商在有明確的BIM範疇與合理預算下執行工作，以改善國內應用BIM技術之環境。;Recently, the BIM (Building Information Modeling) technique has been adopted in building construction projects, with which project execution efficiency and quality have been improved due to enhanced collaboration, reduced conflicts and decreased change orders. Currently, the budgets for executing BIM are estimated based on a percentage of construction costs. This approach is capable of estimating the budgets, but there is no consistent reference percentage and regulation for use. Even worse, the approach can not reflect a reasonable manpower or timesheet for executing BIM works. The purposes of this research are to investigate the problems of estimating BIM budgets in building construction projects, and then to propose a framework and detailed procedures of BIM budgets estimate based on a cost-plus-fee approach. For the BIM works in the contracts of Professional Construction Management and Design-Build, this research has reviewed work items, manpower and timesheets in real cases, collected the price information for different BIM manpower, and then proposed principles of estimating BIM budgets for a client. The workability and reasonability of research outcomes have been validated by real cases and BIM experts. Furthermore, this research also discusses six issues related to estimating BIM budgets and proposes recommendations on those issues. It is anticipated that the proposed approach is beneficial to the client for estimating reasonable BIM budgets and consequently makes BIM contractors completing their works with clear regulations and reasonable costs, that can improve BIM execution environment in Taiwan.
