That industry is large, solid and progressive, leading the world in the size of its construction industry relative to GDP, in the modernity and quality of its constructed facilities, in the size and quality of its physical research laboratories, and in its private and public investments in construction research and development. The Japanese have built an integrated approach toward incorporating new technologies into their design and construction projects and lead in such areas as large-scale bridges, tunnels, soft-ground construction, congested area construction, high performance construction materials, automated "jack-up" erection techniques for high-rise buildings, and computer visualization of residences for prospective buyers. The United States leads in computer integration of design and construction, the economy of constructed facilities, and global positioning systems. The Japanese are generally faster in providing nationwide acceptance of innovations. The Japanese industry has taken strong measures to increase the pace of its internationalization, but still lags both United States and European competitors in market penetration, in large part due to the currently strong yen. Recent economic pressures have reduced the Japanese allocation of resources to construction R&D. The United States and its construction industry can benefit from the practices and innovations developed by the Japanese. While a direct transfer of the Japanese R&D approach and the emerging technologies may not always be feasible, the opportunities for modified application and the potential value of increased U.S. investment in construction R&D should not be overlooked. The U.S. industry would derive considerable benefit from the establishment of a U.S. public/private sector program both to conduct multidisciplinary R&D and to efficiently disseminate evaluated technology focussed in the construction field. KEY WORDS: Construction; construction industry; innovation; Japan ix EXECUTIVE SUMMARY Construction is a major U.S. industry, and the quality of the constructed facilities it produces is important to the competitiveness of all U.S. industry and the quality of peoples' lives. In 1994, new construction amounted to over $500 billion, 8% of the GDP, and employed 6 million people. The global industry is manyfold greater. There is thus both an opportunity for international trade in construction products and services and a concurrent risk of substantial foreign penetration into the U.S. market. Technical leadership is essential to competitiveness in construction in the developed world. Therefore, as part of an effort to benchmark the international competitiveness of major U.S. industries, the Technology Administration of the U.S. Department of Commerce requested this appraisal of technology and innovation in the Japanese construction industry. The project was co- sponsored by the National Science Foundation, the National Institute of Standards and Technology, and the Department of Energy. The study was conducted by an interdisciplinary panel of experts from the private and public sectors. Following collection and review of earlier studies of the Japanese construction industry, especially two organized in 1990 by the Japanese Technology Evaluation Center (JTEC) and the Civil
