With the Internetization of the construction industry, the construction industry has overturned people's traditional concepts, replaced by information technology, industrialization, standardization, globalization, integration and other synonyms. Large construction companies are no longer satisfied with the region, the local local business contracting, but the scope of their own business focus on the national and global scope of thinking, focusing on the "One Belt, One Road" and the Beijing-Tianjin-Hebei, Yangtze River Economic Belt, these important economic growth, and vigorously expanding the outbound market. Traditional regional territorial management is increasingly not adapted to the rapid development of the construction industry day by day, the new open market should be in order to guide the construction enterprises in foreign ports to participate in the local competition, and to provide a fair, just and open market environment for competitors, and as the local industry authorities how to judge and identify the qualifications of construction enterprises in foreign ports, personnel, performance and credibility of the situation will also become a new subject, which will Need industry authorities to the national building construction enterprise related data for uniform standards of entry and timely dynamic management to ensure information symmetry and openness, so the era of big data is bound to become the dominant player in the construction industry, and become an important tool and means to strengthen the service and supervision of the market players.

Big data is the basis of the "four libraries and one platform"

First, popularize what is the "four libraries and one platform"?

"Four libraries and one platform" and the Ministry of Housing and Urban-Rural Development of the national construction market supervision and integrity of the release of the platform, including the enterprise library, personnel library, project library, credit library, the four libraries are interconnected, the ID card can be checked personnel, the name of the unit can be checked personnel, personnel can be checked unit. The function of the platform is to solve the problems of multiple data collection, duplicate entry, authenticity verification, missing project data, difficult to collect integrity information, detachment of market supervision and administrative examination and approval, and inability to link up the two fields of "market and site", etc., and to ensure the comprehensiveness, authenticity, relevance and dynamics of the data, so as to realize the full realization of the national construction market. The goal of informatization supervision of "one data base, one network of supervision and one line of management" is fully realized.

The premise and foundation of the four libraries and one platform is big data, to ensure the comprehensiveness, authenticity, relevance and dynamics of the data; to dynamically record the market and on-site behaviors of all parties involved in the construction project through these data, to effectively realize the linkage between the construction market and the supervision of the construction site, and to comprehensively realize the information-based supervision of the construction market across the country, "one library of data, one network of supervision and one line of management". The goal of informatization supervision of the national construction market is fully realized.

Big data brings new opportunities for development in the field of bidding and tendering

The application of big data in the field of bidding and tendering is mainly in the following three aspects:

Firstly, the use of big data to establish a dynamic procurement information database, which contains the basic information of bidders and tenderers and transaction information. This information helps bidders to find the bidding programs, bid evaluation methods, contract conditions and other contents of similar projects. At the same time, the database can also provide the relevant project's previous contract conditions and various current offers, to facilitate understanding of market conditions.

Secondly, big data provides strong support for bid evaluation. The traditional bid evaluation method is difficult to grasp the consequences of various bid evaluation methods as well as different bid evaluation factors and their weight settings on contract fulfillment. Through big data technology, it can extend the bidder's procurement needs to the contractor's supply chain, analyze the impact of different bid evaluation methods and factors on the final bidding results, and realize the integrated management of the bidder's procurement, bid evaluation committee bid evaluation, and contractor performance to provide support for optimal bid evaluation and reduce the opportunity cost of bid evaluation.

Thirdly, the contractor performance information system is established with the idea of big data, which mainly contains two types of information, i.e., the basic information of contractors and the integrity file of contractors. The above information is obtained from other government departments or public ****resource trading data platforms through networking and becomes an important evaluation factor.

Achieving a nationally unified competitive environment through big data

To make big data a prerequisite for fair competition

Truthfulness, accuracy and inclusiveness are the prerequisites for the use of big data, which should be included in a two-tier meaning here.

To ensure the relative full coverage of information

On the one hand, to strengthen the construction enterprises for the height of awareness of big data, to strengthen the Ministry of Housing and Construction "four libraries and a platform" degree of importance, and to effectively recognize that the information filled in with the future development of enterprises is closely related to the enterprises should be truthful and accurate filling in the relevant information;; on the other hand, the local industry authorities should strengthen the main responsibility for the development of the construction industry and the construction industry. On the other hand, the competent authorities of the local industry should strengthen the main responsibility, and effectively realize who is responsible for the audit, who is responsible for the responsibility. Strengthen the verification of the authenticity and accuracy of the data to ensure that the data is not omitted, not misreported, not concealed.

To ensure the horizontal relevance of information

Big data is to realize the interoperability and interactivity of information, and to realize the linkage of data in various industries. On the one hand, the construction site and the market through big data to realize the "two linkage"; on the other hand, to realize the Ministry of Housing and Construction "four libraries and a platform" and the exchange of data with the relevant departments, give full play to the administrative, judicial, financial, social and other areas of the integrated regulatory effectiveness in the market access and bidding process of the full sector. Market access and bidding and tendering links fully departmental linkage response and breach of trust constraint mechanism. The formation of a full coverage of enterprise data "sky net", to realize the relevant industry sector data horizontal linkage, vertical through.

To make the big data open and transparent sunshine operation

To make the data open, service parties. To gradually realize the unification of the construction market through the openness of enterprise data. Big data mining in the construction industry, there are natural industry barriers. First of all, the data dimension is more complex, both construction data and management data; secondly, the construction industry laws and regulations in each province and city in China are different. In this case, big data mining in the construction industry has become a high threshold industry. Big data is to break the relatively closed barriers of the traditional construction industry, breaking the relationship between each other's independent enterprises and projects. With the intervention of the Internet, the Internet of Things, mobile Internet, with the construction industry unified and open construction market system is gradually established, will certainly break the barriers between the region, enterprises, personnel and performance, to achieve the process of informatization of the construction market, to achieve mutual links and communication, so as to achieve the data of the relatively open service to all parties.

To make the data accurate, sunshine operation

Data accuracy is the basis of fair competition. The data referred to here comes from the declaration and submission of enterprises on the one hand, and from the data automatically generated by the trading system on the other, both of which form the basis of big data. Ensure the accuracy of the data on the one hand, to strengthen the sense of responsibility of enterprises and industry supervision; on the other hand, big data is not a quick fix, a pool of stagnant water, not to mention the "dead" data and rigid data, but by constantly adjusting, updating, interacting, and perfecting the content of the information base, to achieve the implementation of the dynamic management of the enterprise's database, the business and the daily behavioral norms of personnel, rewards and punishments. The daily behavioral norms of enterprises and personnel, rewards and punishments, credit, performance and other timely and accurately reflected in the system platform. The system platform is a timely and accurate reflection of the daily behavioral norms, rewards and punishments, credit, performance and so on.

To realize the management improvement of construction enterprises through big data

From the comprehensive launch of the deepening reform of the construction industry in 2014 to the end of 2015, the central city work conference was held, two years in the construction industry in the survival of the environment, the production mode, the direction of development and so on, there have been radical changes. 2016 the task of deepening the reform of the construction industry is still urgent, how to take advantage of the reform of the turning point in the economic downward trend to grasp the turning point of reform.

Subverting solidified thinking

The value and importance of data in the construction industry in the future will be gradually reflected in the construction enterprise management of qualification data, personnel data, financial data, price data of material procurement, product data of equipment, product safety and quality assessment data, etc. are complex and vast. This requires us to use "big data" thinking to enhance the macro-control and micro-decision-making level of enterprise managers, big data will become an indispensable "core competitiveness" of enterprises. Construction enterprises to improve competitiveness, sustainable development, it is necessary to enterprise main business, core technology and management information to fully realize the data. This is also an effective way to reduce management costs and improve management level. The most critical thing is to change the way of thinking, decision-making methods, and fully utilize big data to formulate enterprise development strategies and make strategic decisions.

To realize the management upgrade

Internet, big data make people's vision become broader, with a global vision to think and solve problems become very necessary. For the construction industry, especially for business managers, the use of the Internet to expand their horizons is particularly important. Changing processes, changing thinking, changing management and production methods is the way out for construction people and construction enterprises to transform and develop. At present, construction enterprises have begun the construction and initial application of information technology, Beijing Sumitomo Group has begun to work and try in this area since 2005, but it still lacks a comprehensive and effective application and integration of information technology, and it is unable to manage the massive amount of project data through traditional methods, so as to realize refined management and analysis. The support of management is data, and the foundation of project management is the management of engineering basic data, timely and accurate access to relevant engineering data is the core competitiveness of project management. The core of big data application and BIM popularization in the construction industry is based on the accumulation, storage and management of enterprise core data.

Service and supervision of construction enterprises through big data

In the age of information technology, the service and supervision advantages of big data are more prominent.On June 24, 2015, the General Office of the State Council issued the "Opinions on the Use of Big Data to Strengthen the Service and Supervision of Market Main Bodies" (Guo Ban Fa [2015] No. 51) in the spirit of the document, which emphasizes that through the use of big data Strengthening services and supervision of market players, and using big data to promote the construction of a social credit system.

Reflecting the sense of service

Traditional data due to restrictions on the specific purpose and objective conditions, resulting in the government information presents a "system of stand-alone" and the split state, often working separately, mutual coordination and communication is not sufficient, so that the formation of various types of data there is reference inconsistent, not standardized, not coordinated, and other defects and deficiencies. Defects and deficiencies. In the subsequent use of data fragmentation, difficult to integrate the use of such issues, thus causing building construction enterprises to participate in the construction of a project, often in the industry in charge of a number of functional departments and offices to repeat the submission of information. Big data is to break the government system division and information barriers set up by the fences and obstacles, it is through the statistical data for multi-objective, multi-angle, deep processing and analysis, horizontal and vertical integration, to build a unified, *** enjoy the data platform, to achieve the unity of the data standards, format and *** enjoy.

Strengthening the regulatory function

Reducing the human factor and utilizing big data for market regulation is a necessary trend for the future development of market regulation. For a long time, the phenomenon of credit failure in the construction market is more prominent, enterprises bid-rigging, illegal subcontracting and subcontracting projects, key technical positions filed personnel and the actual presence of personnel is inconsistent. In the era of "big data", the integrated platform can dynamically record, through the openness of the platform between the system and data **** enjoyment, through the construction market management and effective linkage of construction site supervision, the real realization of the "data a library, supervision of a network, management of a line". Enterprises in violation of laws and regulations and enterprise basic information (qualification, personnel and data) query as well as the realization of bid-rigging, bidding offer evaluation, bid clearing work.
