To integrate and analyze construction information of sports stadiums, airport terminals, conference and exhibition hall, health care facilities, super-tall building types, and infrastructures, etc., this paper studies deeply and systematically on "big engineering data services platform" through key technology support of machine learning and tsecondary development of object-oriented technology from the key points of modern engineering controls. With in-depth analysis and summary engineering data information, the paper establishes a variety of comprehensive index on the basis of construction, design, procurement, construction, operation and maintenance, etc., which could realize forecast analysis, data mining, data visualization, and other functions, comprehensively promote management personnel at all levels in the control of the general contractor works, and enhance the intelligent control of the general contractor technology. The paper combines the design of major projects, subcontract, product supply chain resources, construction organization, and the technical difficult point plan, the new technology as well as the data resources in operation, which helps to give full play to the scale of the enterprise, all kinds of engineering construction of resources integration and sharing, therefore makes all kinds of construction resources to better serve engineering general contracting management and supports enterprises to realize low cost operation and high quality development.
