~Pipe Welding Joint Labor Hour Method~
The author has examined the "man-hours per piping welding joint" for domestic construction, presenting a guideline that is easy to understand and rational even for beginners. While recent construction methods have seen changes, such as the introduction of automatic welding machines, please be aware that the man-hour considerations in this book are based on fundamental construction methods. *Note: The various data in the figures and tables of this book are mostly provided as reference materials for explanation. In practice, please be sure to refer to the latest specialized books and materials.

basic information
In plant construction projects, accurately estimating construction costs is quite challenging. Among these, estimating the costs of piping work, which are significant, is particularly difficult. To improve the accuracy of these estimates, how to calculate the construction man-hours becomes key. Man-hours can vary due to various factors. In practice, it is essential to understand this point well and estimate man-hours that reflect the specifications and construction conditions of the relevant plant. There are published materials regarding man-hours for piping work, but many examples are presented in terms of combined work rates (per meter, per inch, per diameter inch, per ton). Understanding this content and actually utilizing it requires adjustments based on years of experience, making it a challenging task for less experienced engineers. The construction man-hour table is not only for estimates related to bidding. It is necessary data for efficiently executing construction projects, including comparative estimates during the design phase, assessment of outsourced construction costs, change and additional estimates, construction schedule management, and mobilization planning. I hope this information is helpful.

Company information
Since our establishment in 1982, with the support of innovative researchers, engineers, and consultants who resonate with our mission of providing "technical and management information to the industrial society," we have been dedicated to organizing management and technology seminars as well as publishing and selling technical materials. In recent years, the wave of technological innovation surrounding the industrial society has become more intense and faster. In such circumstances, we have focused our corporate activities on a "flexible" response to the information needs of the industrial society. At the corporate level, the number of companies participating in "REIT," which aims to meet 100% of their business power needs with renewable energy, is increasing rapidly. There is also a growing interest in the 17 goals of the "Sustainable Development Goals (SDGs)" related to global challenges concerning the economy, society, and the environment, and ESG investment is gaining attention. Given this situation, we are convinced that technologies centered around energy and the environment, such as those addressing global warming, will become key technologies for the future world. We will continue to focus on information related to "energy" and "environment," and we are committed to providing truly useful information for society and our descendants.
