In recent years, the computer technology interconnection communication system and various terminal equipment system has achieved great development, and our country industry is in the critical period of management transformation, and most industry managers began to take effective measures to inject reform innovation blood, in some actual production process actively implement the standardized standardization and efficient new enterprise management mode. Although in our country is the construction industry to speed up the speed of science and technology development, but at present in the development of information technology, especially the construction engineering quality and safety supervision and management of science and technology information infrastructure related work is relatively lagging behind, lead to the construction of each link of the relevant data information is not comprehensive and timely interactive sharing, make the construction engineering information level is gradually declining. Based on this, this paper analyzes and explores the information construction of construction project quality and safety supervision and management. 展开更多
