| Summary: | 碩士 === 國立交通大學 === 土木工程系 === 91 === In the recent years, Taiwanese government energetically has promoted several major construction projects. According to the schemes issued by the Executive Yuan in 1995, the Public construction Commission (PCC) started a serious of fundamental, integrated, and interrelated plans on the “Technical Database Integration Program for Public Construction Works (or termed as four-in-one plan)”. Under this integration program, each plan must horizontally and vertically connect to the other so that the program can work effectively.
While the government has actively promoted this program, practitioners have criticized this four-in-one plan and argued that this program cannot support the project tendering efficiently. The objectives of this study are to in-depthly analyze the workability of these programs individually and integratedly. Such an analysis is performed by using a questionnaire survey and the Data Flow Diagrams (DFD) technique. The analysis results reveal that several drawbacks can be found in the horizontal integration between these programs. To overcome these drawbacks, this investigation further uses the DFD technique to develop an information flow model to improve the current four-in-one plan. The improved plan is expected to work successfully in generating the project tendering packages (including design plans, specifications, and estimation) automatically. The research results are demonstrated by an example of “cantilever retaining wall” construction project.
