For example, for a road engineering plan, the project plan may include a affair template which is named soil protection and descent, the workload includes earth and stone excavation, transportation, backfilling, ground leveling, precipitation, drainage and earth wall support, and the task amount configuration unit is used for configuring the type and the number of the workload and setting a corresponding numerical range; the digital model unit is used for initializing a GIS model of a project, when the GIS model is lost, a public GIS model (3 Dtiles, geojson) is built in a transaction template, an upper layer of the GIS can be used for identifying schedule arrangement of the project, and the input configuration unit sets input data sources comprising a temperature and humidity sensor, a project range, a risk area and a site sensor monitoring point; the risk calculation configuration unit is used for configuring the risk calculation unit to realize risk assessment, and comprises the following steps: construction is not permitted under geological conditions, construction is not permitted under meteorological conditions, and an engineering safety system does not reach the standard, GIS space analysis is combined with sensor monitoring data analysis, so that a risk coefficient is output, if the risk coefficient is 0, construction can be performed, if the risk coefficient is 100, construction is forbidden, and GIS visual display is performed on risks.

The engineering affair item can be obtained after the configuration of the affair template, the engineering affair item is activated when the engineering affair item is initialized, the engineering task amount management unit stores a list of civil engineering amount and a task plan, an API related to the weather class in the input unit can directly apply data in the affair template, a sensor related to a construction site inputs and prompts a user to input an address of an information source or an address of a database by providing a user interface, a user chart inputs are related to the user, and the user can input information such as PDF, excel and the like by providing the user interface; performing attribute binding on the engineering affair item and the Polygon of the layer of the GIS model, and updating the position of the Polygon point when the task quantity is changed; the risk calculation unit of the engineering affair item outputs results of no risk, low risk, medium risk and high risk according to the risk index obtained by calculation; the corresponding results may additionally include other attributes such as risk range, risk type, which may be output in JSON format or saved directly into the database.

The transaction template identifier can avoid creating engineering transaction items which have the same name but do not belong to the same type of transaction when creating the engineering transaction items.

The workload of the engineering affair item can be measured, so that the actual progress is the ratio of the completed progress to the overall progress, such as 10%,25%,50% and 95%; when the workload is adjusted by the risk assessment system, the corresponding schedule is changed accordingly. The corresponding schedule representation may also be expressed in terms of milestone events such as work development, license acquisition, project halving, and acceptance.

Taking a non-engineering type affair template as an example, for a planning and designing template as an example, the affair template comprises work of non-actual engineering quantity, such as a land application report and a construction land approval book, a terrain measurement and land dial measurement result report, a construction land file transfer, a construction land planning license (including temporary), and a diagnosable opinion related to ring appraisal. Taking the construction site planning license (including temporary) as an example, the corresponding transaction template can be set as a digital model attribute: a layer of the construction area related to the geographic information model; the workload is that the preparation of declaration materials is completed, and the handling of planning licenses is completed within a specified time; an input configuration unit; user input or government public information query acquisition; an output configuration unit: binding the engineering affair item with the Polygon attribute of the layer of the GIS model, and updating the point position configuration of Polygon when the task quantity is changed; risk matching defines that no permission results on a given web site are obtained within a contracted time.

The workload of the engineering affair item can not be approximately measured with the actual field type engineering quantity, but the actual progress only comprises incompletion and completion, and the corresponding progress can be represented by using milestone nodes, such as project start, license application, material submission and project acceptance.

Other transaction templates contained within the project template may be initialized in a similar manner to obtain a list of engineering transaction items, which may include both field type transactions as well as written transactions.

The scheme relates to two types of typical engineering task quantities, however, the affair template is also suitable for creating other types of engineering affair items, such as decoration engineering, the total workload is the engineering quantity corresponding to the total used materials, the current progress is the workload corresponding to the completed materials, and the data source is report information input by a user or verified purchase information or BIM information; corresponding project schedules of 0, 20, 50%, etc.; if the safety training or the project communication meeting in the process of the project is carried out, the progress information is 0, 10 percent, 8230, 100 percent respectively according to the times of the meeting; and a risk calculation unit can be set to prompt risks according to the loss of safety training.

In one embodiment of the invention, the transaction template further comprises a common information model unit for initializing a digital information model of the engineering project according to the engineering workload. Because the basic conditions of the projects are inconsistent, not all projects can be provided with GIS or BIM in the bidding stage, in addition, in the project starting process, a project plan is changed by an owner or the project plan is required to be changed according to local conditions in the construction process, in this case, an information model for the project is missing, and a digital information model of the project should be initialized by introducing the model or multiplexing other models. In the invention, more than one digital model can be obtained by processing the models of the historical items, after sensitive information is removed, a desensitized digital model can be obtained, and the digital model can be used for initializing digital information models of other items. For typical scene purposes such as interior decoration projects, for the engineering quantity similar to the design structure, a digital information model can be obtained by adjusting the workload, such as modifying the material, quantity and unit price, and is used for tracking the project at the later stage.

As an improvement of the above technical solution, the project template further includes an activation configuration unit, configured to configure a dependency relationship of the engineering transaction items, where the dependency relationship includes a dependency relationship between the engineering transaction items or a dependency relationship between the engineering transaction items and the digital model. Because engineering projects are often performed in parallel, and a dependency relationship may exist among a plurality of workloads, for example, equipment installation should be performed after civil engineering is completed, the dependency relationship among engineering affair items can be configured by activating a configuration unit, so as to be used for the dependency relationship among key nodes according to a construction site.

the risk evaluation module does not evaluate the engineering affair items in the inactivated state when evaluating the risk, and the information input module only forwards the input information to the activated engineering affair items. When the engineering affair item is activated, the engineering management unit registers the engineering affair item to the information input module, and when the engineering affair item is completed, the registration of the corresponding engineering affair item is removed, so that the information cannot be forwarded to an unrelated interface, and the data management risk of the project is reduced.

As an improvement of the above technical solution, the engineering transaction item unit includes a transaction item initialization unit for initializing the engineering quantity of the engineering task quantity management unit, and the transaction template further includes an initialization configuration unit for initializing the transaction item initialization unit of the engineering transaction item. Due to the complexity of the construction project, the project amount may change in the process of project progress, so that an initialization unit and an initialization configuration unit may be configured to perform accounting on the actual workload in the project initialization stage, thereby avoiding the workload shortage or the repeated calculation of the workload.

As an improvement of the above technical solution, the system further comprises a rendering unit, and the rendering unit is configured to generate a view for prompting the risk information according to the engineering transaction item. When a CS architecture is employed, risk assessment and presentation can be provided in the form of, for example, a large data screen.

As an improvement of the above technical solution, the bidding document contains a building information model, and elements of the building information model contain a first task label;

or the text description of the bid document contains a first task label;

the first task label is used to indicate a division, progress node, or milestone event of the construction project. The milestone events of the thermal power plant are different according to engineering projects, for example, for thermal power projects, the milestone events can comprise the steps of excavating a main plant, pouring first tank concrete on the foundation of the main plant, hoisting a boiler steel frame, hoisting a heating surface until the thermal power plant is started for the first time in a complete set. The task tag of (a) may be consistent with an identifier of the transaction template within the database or may be matched to the transaction template through a mapping. For example, when the project transaction item is a claim approval item, the task tag may include the name of the approval item and be included in the technical document, and when the bid document is parsed, the task tag is parsed to the project transaction item of the claim approval item.
