One possible measure to streamline on-site construction and promote the modernization of construction sites is to use newly developed technologies at construction sites. In this study, as a way to make use of newly developed technology, we presented one approach to consider its application to construction sites by rationally evaluating the developed technology. As a means of rationally evaluating the developed technology, we attempted to compare conventional standard construction with construction using the developed technology.
This research uses the high-performance concrete, which does not require compaction, as an example of newly developed technology, and evaluates the application of high-performance concrete to construction sites by comparing it with conventional standard construction in terms of labor savings and shortening the construction period. In the process of examining conventional standard construction, we also examined the future direction of construction productivity by analyzing it that has been taken into account in standard cost estimation for public works projects.
