| Summary: | 碩士 === 國立中央大學 === 營建管理研究所 === 101 === In Taiwan, owner prepares budget for construction overhead by a fixed percentage fee, most of them in the scale of 5% of the contract value. This fee does not count in accord to duration, site, or construction sophistication of the project configuration. By interviewing construction overhead budget experts and reviewing related literature, a parametric model by Multiple Regression Analysis for construction overhead is proposed. Construction owners can adopt it to budget construction overhead objectively.
The core of the study is to establish parameters used in the model. Nonetheless, due to insufficiency of data, the limit of this model is: Project Duration between 525-1002 days, Project Cost between 217.961 to 160 million, and the Difficulty Score (require the use of assessment methods in this study) is lower than 3. Different companies using this model will have errors, but the overall accuracy will still be above 80%.
