vision tower and the bridge ramp Zhang, are cases in point. Use of project management information platform, , video conference system three system for the project provides a advanced modern information transfer and the means of exchange, make the project information sharing more in time, more agile and more widely, and have the different interactive discussion of the implementation of the environment, involved in the project staff in the world within the scope of the any place convenient check project management information, headquarters staff can also access management of other place orders management information, understand the overall project, through the database, the part of the division, construction site, such as subcontractor closely together, create a distributed collaborative working environment, and can implement different ground mand and control. Civil engineering information already, include the construction management of information also includes building technology development of information, construction management information should be in the open on the three levels, namely, in civil engineering industry management information, work process project management information, civil engineering enterprise management information. Civil engineering industry management informationization is the root, embodies the characteristics of the industry and business market characteristics of the industry。s water supply project, colosseum amphitheater (Rome large animal fighting Field), as well as many other wellknown churches, palaces and so on. After the industrial revolution, especially in the 20th century, on the one hand, civil society to put forward a new demand。s mechanics, material mechanics, structural mechanics, structural engineering design theory came into being, and so on. Construction machinery, construction technology and construction anization design theory also development, civil engineering from the experience of rising to bee science, engineering practice and theoretical basis for both is a different place, which led to more rapid development of civil engineering. During the nieenth century, 20, made of Portland cement, concrete has e out. Concrete can aggregate materials, easytoconcrete structures forming, but the tensile strength of concrete is very small, limited use. By the middle of the nieenth century, the surge in steel production, with the emergence of this new type of reinforced concrete posite construction materials, which bear the tension steel, concrete bear the pressure and play their own advantages. Since the beginning of the 20th century, reinforced concrete is widely used in various fields of civil engineering. From the beginning of the 1930s, there have been prestressed concrete. Prestressed concrete structure of the crack resistance, rigidity and carrying capacity, much higher than the reinforced concrete structure, which uses an even wider area. Civil Engineering into the reinforced concrete and prestressed concrete dominant historical period. Concrete buildings to bring about the emergence of new economic, aesthetic structure in the form of engineering, civil engineering so that a new construction technology and engineering design of the structure of the theory. This is another leap in the development of civil engineering. A project to build the facilities in general to go through the investigation, design and construction in three stages, require the use of geological prospecting projects, hydrogeological survey, engineering survey, soil mechanics, mechanical engineering, engineering design, building materials, construction equipment, engineering machinery, building the economy , And other disciplines and construction technology, construction and other fields of knowledg
