Description

A multi-professional coordinated construction management system based on BIM technology

Technical Field

The present invention relates to the technical field of building engineering construction, and in particular to a multi-professional work type coordinated construction management system based on BIM technology.

Background Art

The core of BIM technology is to establish a virtual three-dimensional model of a building project in a computer, and use digital technology to provide a complete and actual building project information database for this model. This database not only contains geometric information, professional attributes and status information describing building components, but also contains information on non-component objects (such as space and motion behavior). With the help of this three-dimensional model rich in building project information, the degree of information integration of building projects is greatly improved, thus providing a platform for engineering information exchange and sharing for stakeholders in building projects. Combined with more relevant digital technologies, the engineering information contained in the BIM model can also be used to simulate the state and changes of buildings in the real world, so that before the building is built, stakeholders can make a complete analysis and evaluation of the success or failure of the entire project.

Nowadays, BIM has already completed the transformation from pure theory to engineering application. As a new development trend and direction of the construction industry, it has brought huge challenges and opportunities to the entire construction industry from design to construction, and then to the subsequent management and operation. With the help of BIM models, designers can make detailed comparisons of existing plans and make scientific and reasonable optimizations based on actual conditions. As the actual builders of the project, construction units can also obtain more and more reliable technical information through BIM models to achieve refined construction and ensure construction quality: project managers can use BIM ideas combined with 4D simulation construction technology to more efficiently carry out project management. In addition, during the normal operation of the building structure, mature BIM models can also provide great help to the maintenance and overhaul of facilities in property management.

Construction organization is an important means of scientifically managing construction activities. It determines the content of construction preparation work at each stage and coordinates the relationship between various construction units, professional construction types, and various resources during the construction process. Construction organization design is a comprehensive technical, economic, and organizational solution to guide various activities throughout the construction project. It is the product of the organic combination of construction technology and construction project management. The use of BIM technology can solve the current situation of high difficulty and irrationality in construction organization.

DETAILED DESCRIPTION

According to an embodiment of the present invention, a multi-professional work type coordinated construction management system based on BIM technology is provided.

The present invention is further described in conjunction with the accompanying drawings and specific embodiments. As shown in FIG1 , a multi-professional type of work coordinated construction management system based on BIM technology according to an embodiment of the present invention comprises the following components: a visual building model unit 1, a real-time construction monitoring unit 2, a project progress prediction unit 3, a type of work process coordination unit 4, a construction risk assessment unit 5, a project cost estimation unit 6, a project comprehensive evaluation unit 7 and a project database 8;

The visual building model unit 1 is used to construct and display a visual BIM information model;

The visual building model unit 1 includes an original engineering database 101, a building model building module 102, a construction data synchronization module 103 and a model output classification module 104;

Wherein, the original engineering database 101 is used to store the original engineering data of the building to be constructed;

The model building module 102 is used to build a three-dimensional visualized BIM information model of the building to be constructed according to the original engineering data;

The construction data synchronization module 103 is used to obtain the engineering construction data collected in real time during the construction process, and synchronize the engineering construction data into the BIM information model as a parameter input;

In addition, the construction data synchronization module 103 uses the COBie standard for data exchange and synchronization, and the data exchange and synchronization formats include IFC-STEP, ifcXML and Spread-sheetML.

The advantages of adopting the COBie standard are as follows:

(1) The COBie standard exists throughout the entire life cycle of a construction project, and people involved in the project at all stages can add and modify data information.

(2) COBie data divides the information data generated in the project more reasonably. The COBie standard divides information according to spatial areas. When dividing areas, it does not simply divide and distinguish by horizontal and vertical coordinates as in the BIM model, but integrates countless small spaces with the same attributes through the natural attributes of the space. Such spaces are no longer just independent individuals, and the division is clearer, which helps facility managers find the location of facilities more quickly and accurately when performing facility maintenance, so that facility management work can be carried out efficiently.

(3) The COBie data management method adds descriptions of building facility resources, documents and other information. By retrieving and viewing document data, the location and specific properties of a building component can be quickly and accurately understood. In addition, the COBie standard is an internationally accepted standard that does not simply serve a certain software, but sets certain standards for information delivery according to the information needs of facility management. It can better solve the problem that different software cannot work together due to different data interfaces.

A multi-professional coordinated construction management system based on BIM technology according to claim 8, characterized in that the intelligent identification and analysis of risks existing in the construction process in combination with the BIM information model to achieve risk warning includes the following steps: Building a risk identification rule base based on the BIM information model, defining the risk factors existing in the construction process as a number of rules, and numbering the rules; Search and match by rule number, extract the rules and find the corresponding rule premise; Calculating the credibility of each rule in combination with the fact case base; Summarize the number of risk factors in the construction process of a single construction project, and calculate the credibility of multiple rule combinations as the risk assessment value. The formula is:

; If the risk assessment value is greater than or equal to the preset threshold, it indicates that there is a risk hazard and a risk warning is issued, and the assessment result is transmitted to the security risk knowledge base, and the risk prevention and control measures are matched and output in the risk measure library; If the risk assessment value is less than the preset threshold, it indicates that there is no risk hazard; In the formula,

represents the risk assessment value;

Indicates the weight value of each risk factor;

Indicates the confidence level of the rule represented by each risk factor.
