運用資料流程圖建構先期規劃需求整合流程模式

Abstract

公共工程於先期規劃階段的需求整合作業對後續工程進行順利與否有著極重要的影響。在此階段，工程主辦機關（業主）需要整合各種需求據以概估工程經費，進而擬定徵選建築師之招標文件。實務上各工程主辦機關多為非工程專責機關或有專業人力不足的情形，常使業主無法明確的整合出需求，以致將錯誤及不足的需求訊息傳遞給建築師，進而衍生出後續設計階段需經過冗長且複雜的需求探討作業，後果往往導致工程成本浪費與期程的延宕。 本研究模式係建構在「各機關辦理公有建築物手冊」內容中，敘述先期規劃作業辦法及規定的基礎上，配合專家訪談瞭解先期規劃整合作業內容之主要整合重點，再予以探討實務案例於執行先期規劃需求整合作業的操作經驗後，利用資料流程圖（DFD）模式化方法將先期規劃需求整合作業操作過程予以系統化的呈現出來，模式之功能除了引導使用者進行需求整合作業外，更提供一個具體化的作業流程，以使使用者知道該得到哪些作業資料或資訊，且進行哪些作業步驟以完成需求整合作業，以提高需求整合作業之效率及整合內容之確實。

Public construction in owner’s needs of construction projects of advanced planning phase has a respectable influence for subsequent development. In this phase, the construction competent authority (the owner) may integrate all needs to estimate expenditure generally, and then frame the auditioning architect documents. In the practice, the owners are not major in construction or lack of professionals, and the owners would not able to integrate needs particularly so that convey the erroneous and insufficient needs information to architect, moreover, derive lengthy and perplexed needs conference operations in the post-design phase that results in consequence of consumed construction cost and delayed progress. The model of this study is based on the regulations and rules of advanced planning in The Operations Companion of Establishment Transacting Public Construction and collates the interviews of professional to realize the integration emphasis about owner’s needs of construction projects, and then, after probes into the practical examples about experiences of the projects, applies data flow diagram (DFD) to derive the projects systematically. The functions of model not only guide users to integrate needs but provide a concrete operation process, which informs users about what information and which operations steps they needs; so that may upgrade the efficiency of owner’s needs of construction projects and implement the integration distinctly.
