| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 103 === Many constructed projects have problems of interface conflict, design changes, constructability and so forth. They are caused by poor planning and resulted in schedule delay and supplementary budget. Since design quality control will heavily affect the success of the project. This study will explore piping design, which needs the most interface integration and is the most complex among projects of domestic production facilities plants.
This research focused on the detail design stage, and analysis of the factors affecting quality of piping design. This research put forward 36 factors to be considered in piping design and suggestions for selecting graphic software through sorting contents of the pipe design work and engineering design drawings. Meanwhile, sorting out the factors was through expert questionnaire survey. The collected survey data were tested by descriptive statistical, analysis reliability analysis, one-way analysis of variance and paired sample test methods. And the follower 12 items were significantly identified and recommended for consideration in the selection graphic software as followed:
(1)「ability to interface integration with other engineering function.」
(2)「convenience for modify the design, flexible piping design modifications.」
(3)「detected mistake on modeling automatically.」
(4)「correct in piping material take-off.」
(5)「correct in to generate piping isometric drawing.
(6)「To build 3D piping model according to piping material specification.」
(7)「The period of build 3D piping model - to be short.」
(8)「The period of build 3D pipe support model - to be short.」
(9)「To execute interference check」
(10)「the interoperability of data base between the different software」
(11)「the compatibility between the different software」
(12)「set up a fertile piping Catalogs (ANSI-ASME, JIS, DIN, AWWA ...)」
The above 12 items would facilitate the selection of an economical design tool with better manpower arrangement, as well as with better design quality.
