高科技廠房於規劃設計階段成本管理之探討

Abstract

中文摘要

工程專案成本之控制為整個工程專案的重點管理項目，因為如何在有限的預算經費中，有效率的控制專案成本，並順利完成工程，是專案管理人員的最終目標。雖然規劃設計階段成本管理為爾後營建作業的執行依據，但工程專案人員在進行規劃作業時，常因工作的職別不同(設計單位、主承包商、顧問、業主)或因使用性(生產設備與製程)的不同而對其所決定的會有所差異。該如何規劃討論出最合理的成本乃是專案管理人員所應關心的重要課題。 回顧國、內外文獻與成本相關教科書較少對上述問題進行深入之案例分析與探討。過去科技廠房的研究大都偏向進度、品質、營運管理與型式層面，關於造價管理的研究較少。廠房工程為複雜大型之工程，其所牽涉的層面與涵蓋範圍金額漸龐大，在規劃設計階段亟需討論與分析清楚。本研究透過問卷調查與實際案例資料分析，對工程規劃設計階段成本管理課題作一初步的探討。 根據本研究所建構的規劃設計階段造價管理架構，經問卷調查共可歸納出11項關鍵項目，其中又以柱位柱距、結構系統、建築用途系數I值與地震係數、樓層與樓高、建築物尺寸最為關鍵。本研究另依據評估項目，結合訪談記錄與實際案例分析結果作分項重點說明，以提供未來規劃設計階段造價管理所需的決策參考，並可供教育訓練使用。

ABSTRACT Cost control is one of the key items of project management of building construction. To control the cost effectively and finish the construction successfully within limited budget is the ultimate goal of project management. The building cost control in planning and design stages are the basis of future construction operation; however, the decisions made by project managers are often different due to the different background of professions ( designer, general contractor, consultants and owner), or the differences of usages, such as facilities and process of manufacture. Therefore, planning of concluding the most reasonable cost shall be one of the most concerned subjects for project manager. The documentation and textbooks relate to cost control rarely have in depth case analysis and investigation retrospectively to the subject above. Also, the research of high-tech fab often focus on the schedule, quality, and management or styles of operation, and rarely in the field of cost management. The construction of fab is big and complicated respectively, and its interface and budget grows immensely. It is important to discuss and analyze thoroughly during planning stage. This research is to study the issues of cost management in planning and design stages by collecting and analyzing interviews and actual cases. There are 11 key items of cost management in planning and design stage respectively, according to the hierarchies of cost management in planning and design stage established in this research. Among them, the column spacing, structure system, the I coefficient of structure design and earthquake variable, the number of floors and floor height, the size of building are the most important factors. This research illustrates the analysis of the interviews and case studies, based on the evaluation items, and with anticipation, can be used as reference of project management in planning and design stage in professional practice as well as in training and education.
