| Summary: | 碩士 === 國立成功大學 === 土木工程學系碩博士班 === 95 === Coordination is the critical factor of successful construction projects. Due to uniqueness of the construction project and habits of engineering personnel, coordination is usually not well planned and results in spending much time and money, yet the performance is not as expected.
This study investigates the method of coordination and time allocation of engineers with other four type projects. (sanitary sewer, road, building and plant).
Coordination can be classified into nine methods: meeting, site visits, informal discussion (including face to face and telephone communication), correspondence, schedules, plans, reports, and contract documents. Top level managers spent more time on meeting (26%). Middle level engineers spent more time also on meeting (22%). First-line engineers spent more time on site visits (25%). Engineers all spent more than half of their time in individual work.
Meeting took a lot of time of engineers. Six types of meeting minutes were collected and analyzed. The results show that schedule is the most common topic in meetings, and non-technical occupied 46% of all issues. These non-technical issues such as work coordination and interface communication can not be ignored in construction coordination.
In the investigation of other four types of construction projects, it is found that contractors spent most time on site visits (40%). The contractors of public sanitary sewer and road work projects spent most time on site visits (46%, 53%), but only spent 3% on information collection. On the contrary, the contractors of private building and plant work spent more time on information collection (7%, 8%). The result implied that requirements of private owners require more facts based deta.
In summary, the engineers spent time on the first three coordination methods are site visits, correspondence and meeting. In addition, the percentage of site visit alone is high, so its effectiveness is worth further study.
