| Summary: | 碩士 === 國立雲林科技大學 === 營建與物業管理研究所 === 99 === With the increasing age of the paving road system in Taiwan, its structural conditions and ability to last longer along with lower maintenance has become a more frequent problem. The repaired quality is different from place to place. After summarizing literatures on the factors that affect pavement quality, this study probes into the management level at all stages of the life cycle. This study focuses on urban road pavements to help managers understand all the various factors into better quality of paving.
During this study a reoccurring problem which came from poor communication within the public sectors personnel was found. It ultimately resulted in schedule delays. More problems have also arisen within the developmental stage of planning in the private sector. The importance of quality execution at delivering the best final product is more important than the individual views of the public sector .
SEM path analysis found that there were some key important issues for pavement quality along with life cycle phases, as followed:
Planning phase: Geological surveys were not carried out as to local planning procedures.
Design stage: The designer did not provide detailed or specified drawings pertaining to a specific project.
Bidding stage: Contractors failed to oversee the management of construction and the quality of final execution. Individual error is the result of poor management.
Construction phase: Inadequate supervision during construction resulted in improper procedures being used and essentially resulting in bad construction. Compaction procedures were not followed and the base was uneven paving.
Operational phase: Manhole covers and pavements began to converge.
Maintenance phase: During maintenance procedures, transportations of materials were inappropriate and dangerous and should be evaluated by public sectors and scrutinized by managers.
The most essential and important part of the planning phase is ultimately the daylight working hours. This is essential to production and productivity. Contractors need to manage all aspects of a work site from staff all the way down to materials used. Perfection and a final end product worth being proud of should be every contractors first and only goal.
