The introduction of 3D technology for the construction industry will probably promote specialization rather than become popular self-build. This is because the knowledge required in terms of information technology significantly differs from the knowledge required in traditional construction industry. The general contractor is responsible for production design and the creation of production data, the processing company will expand the innovative business using the NC-machine, and the sub-constructor will be undertaking assembly activity with a little profit that nobody wants to do it. However, modularization in construction production system will contribute to the development of new technology increases productivity. In addition, general contractor must show the direction of technological development of software and machine maker and integrate a variety of techniques. And popularization of 3D technology has the capability for changing the system of traditional construction industry.
