Keeping pace with the development of the industry, comprehensively improve the construction quality of the prefabricated building, so that the construction and quality inspection of the integrated monolithic concrete structure project can be more rational and evidence-based. The Shandong Provincial Academy of Building Sciences took the lead in revising the "Assembly of Integrated Concrete Structure Engineering and Quality Acceptance Regulations" (DB37/T5019-2014), and participated in the "National Assembly Building Industrialization Base" by Changda Building Technology Co., Ltd. The preparation of the revised draft of this procedure, the general manager of Changda Jianke Zhoukejia participated in the establishment of the establishment team and the first working meeting.

       The development of prefabricated buildings is a major change in the way of construction and an important measure to promote the transformation of new and old kinetic energy and the development of new urbanization. It is conducive to improving labor productivity and quality and safety. It is conducive to promoting the deep integration of construction industry and information industrialization, cultivating new industries and new kinetic energy, and promoting the elimination of excess capacity. In recent years, China has actively developed and explored prefabricated buildings. Since the State Council executive meeting deliberated and approved the "Guiding Opinions on Vigorously Developing Prefabricated Buildings", the policy of developing prefabricated buildings from the central to local governments has been introduced in 2016. The preparation and promulgation are also on the agenda. In 2018, prefabricated buildings became the focus of construction work in various regions.

       In today's increasingly fierce competition in the construction industry, Changda Jianke provides customers with modern, livable building solutions integrating design, manufacturing, transportation, assembly, decoration and intelligent home through technology research and development and industrial integration. In the future, the company will further optimize the design of prefabricated products, greatly improve the quality and performance of building products through product upgrades, and improve the overall quality of the building; comprehensively create the modernization, standardization, standardization and branding of the construction industry.
