碩士 === 明新科技大學 === 營建工程與管理研究所 === 99 === “Construction cost” is that every investor wants to minimize; on the other hand, every investor wants to maximize “net profit”. Hence, it is valuable to study how to achieve “minimum construction cost and maximum net profit”. Many studies focus on reducing the cost but their approach and analysis are not on the base of real practice on the construction site. This research aims to employing site experience of the researcher and the survey of expert’s interview to understand the effective factors in reducing the cost to a reasonable level. The questionnaire includes the following information: A. The management of the construction company; B. The control of the volatile basic-unit labor; C. Cost of execution. This study uses Analytic Hierarchy Process (AHP) tool as the method to analyze the collected thirteen cases. It shows that the effective factors in reducing the cost. The results are arranged in the order of effectiveness: 1. The establishment of prompt and the effective reward system; 2. The separation of power of the company and the work-site purchase from the human resource office, but under a centralized control; 3. Cautious selection of contractors, who can grow with the company; 4. An authoritative budget system; 5. The control of personnel in an effective scale to reduce labor cost; 6. The collaboration among the departments of construction, purchase, and sales; 7. The improvement of working conditions and work morale to encourage effective work; 8. The establishment of strategic alliance under the principles of the scale of the cases; 9. Within a reasonable scope, the reduction of work schedule to reduce the management cost; 10. The training of laborers in technical work to achieve the goal of the division of labor. The first effective factor, “the establishment of prompt and the effective reward system” shows 0.4618 in AHP. The second in line, showing 0.3370 in AHP, is “the separation of power of the company and the work-site purchase from the human resource office, but under a centralized control”.
