In the embodiment of the present application, there may be various ways to create the BIM. In specific application, the BIM of the project in the construction stage can be established according to engineering requirements, and detailed nodes are optimized. Specifically, when building the BIM, the engineering civil engineering model in the BIM is built by Revit software, the steel structure part is built by Tekla, all part models are integrated after being built, the parts are exported into an obj format file in a data output mode, and the integrated BIM is imported into a BIM platform.

In practice, the ready-mixed concrete file may be in the form of an electronic version of the ready-mixed concrete order or the like.
Specifically, the staff can fill the premixed concrete entrustment book in a system, and automatically generate a two-dimensional code at the upper left corner of the premixed concrete entrustment book through the system, wherein the two-dimensional code contains all information in the premixed concrete entrustment book, and the method comprises the following steps: and the related information such as casting position, casting time, concrete volume, concrete label and the like.

In step S104, the method may include: identifying a key path in the double-code network graph, comparing front edges, and determining the progress state of each part in the project on a key node and the total construction period, wherein the progress state can be one of the following states: advanced status and days in advance; a normal state; hysteresis status and hysteresis days. Therefore, the method and the device can identify the key path through the double-code network diagram and automatically calculate the conclusive data of the engineering construction progress through the front-line method.
In this embodiment of the present application, the progress status determining system 22 may be specifically configured to identify a critical path in the double-code network graph, perform a frontier comparison, and determine the progress status of each part in the project on a critical node and a total construction period; the progress status is one of: advanced status and days in advance; a normal state; hysteresis status and hysteresis days.

In step S105, the advanced or delayed state and the number of days of different parts may be displayed in a form of deepening color, so as to achieve the function of three-dimensional visual early warning. For some examples, step S105 may include one or any combination of the following: 1) rendering a part in the building information model through a first set color when the progress state of the part is an advanced state; 2) when the progress state of a part is a normal state, rendering the part in the building information model through a second set color; 3) rendering a part in the building information model through a third set color when the progress state of the part is a lagging state and the lagging days are less than or equal to a preset threshold value; 4) when the progress state of a part is a lagging state and the lagging days are larger than the preset threshold value, rendering the part in the building information model through a fourth set color; wherein, the color depth of the fourth setting color can be larger than the third setting color, and/or the color depth of the third setting color can be larger than the second setting color, and/or the color depth of the second setting color can be larger than the first setting color. Therefore, the early warning device can display the early, normal and lagging states of different parts through different colors, and quickly identify different lagging days in the lagging state through the depth of the color, so as to achieve the early warning effect. By checking the color of each part in the BIM, related personnel can intuitively and clearly know the advance or delay condition of each part of the construction progress in the construction site. Particularly, the method is more visual and clear aiming at the delay condition of the key nodes of the milestone, and is convenient for managers to take corresponding measures in time, so that the aims of early warning and correcting the delay of the construction period in time are fulfilled.
For example, the first setting color may be set to "green" in advance, the second setting color may be set to "blue" in advance, the predetermined threshold may be set to n (n is an integer not less than 1 indicating the number of days), the third setting color may be set to "red", the fourth setting color may be set to "deep red", so that a component whose progress status is an advanced status will appear to be "green", a component whose progress status is a normal status (i.e., actual progress is performed according to the original progress plan) will appear to be "blue", a component whose progress status is a delayed status and the number of delayed days is less than or equal to n will appear to be "red", a component whose progress status is a delayed status and the number of delayed days is greater than n will appear to be "deep red", so that the advanced and delayed statuses are intuitively judged through the display color display of the BIM, and when the time lags for different days, the BIM model has different deepening degrees and is clear at a glance, and the function of early warning is achieved through color inspection.
In practical applications, the predetermined threshold may be freely set according to practical situations, and the predetermined threshold may be set as a fixed value (e.g., an empirical value) or may be set as a dynamically changing value, for example, the data may be dynamically adjusted based on the engineering-related information.
In the embodiment of the application, the BIM platform can also display the progress state through the data link behind the platform project list, so that managers can conveniently and visually see the progress condition of the project so as to manage the project. Or the BIM platform can display the progress status in a navigation bar in the form of an interface, so that managers such as project leaders and company leaders can conveniently view the progress status.
