Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular to a bridge dynamic assembly and resource allocation method based on BIM technology. Background Art

[0002] At present, with the continuous development of bridge technology, the complexity of bridge structure and construction is increasing. The entire bridge construction process is usually divided into multiple processes, each of which involves corresponding engineering quotas, such as personnel, machinery, and material inputs, and different processes are connected in time. When dealing with complex bridge construction, due to the complex and changeable construction conditions, the construction organization design is adjusted according to the actual progress of the site. For example, if the execl table is used, due to the mutual influence between different processes and engineering quotas, the adjustment is only made through the execl table. Not only is the process complicated, but it is also relatively lagging, which leads to low efficiency in the turnover of resources such as machinery and materials between different projects. Summary of the invention

[0003] The present application provides a method for dynamic bridge construction and resource allocation based on BIM technology, which solves the technical problems of delayed construction adjustment according to actual progress and low resource turnover rate in related technologies.

[0004] The present application embodiment provides a bridge dynamic construction and resource allocation method based on BIM technology, which includes the following steps:

[0005] Establishing a BIM model of the bridge in the BIM system, dividing the bridge into multiple components according to the BIM model, dividing the construction process of each component, and performing engineering quantity statistics;

[0006] Enter the construction process, theoretical duration and connection sequence of each component into the BIM system to automatically generate a construction schedule for the bridge project;

[0007] Determine the corresponding engineering quota according to the engineering quantity of each component, enter the engineering quota of each process into the BIM system, and automatically generate an engineering quota demand plan in combination with the construction schedule of the bridge project;

[0008] The construction schedule and engineering quota demand plan of the bridge project are revised according to the actual construction progress, and the construction schedule and engineering quota demand plan of the bridge project are dynamically adjusted;

[0009] Resources are allocated according to the bridge project construction schedule and engineering quota demand plan.

[0010] In one embodiment, the engineering quantity statistics are performed by sub-items of the project.

[0011] In one embodiment, the components of the bridge include at least pile foundations, abutments, piers, main towers, main beams, and cable-stayed cables.

[0012] In one embodiment, the bridge project construction schedule and the engineering quota demand plan are modified according to the actual construction progress, and the bridge project construction schedule and the engineering quota demand plan are dynamically adjusted, including:

[0013] The actual construction time of the previous process is entered into the BIM system to dynamically generate the bridge project construction schedule and engineering quota demand plan for the next process.

[0014] In one implementation, when the actual construction time of the previous process is entered into the BIM system, the actual start time and the actual completion time of the process are entered on a daily basis to correct the theoretical duration.

[0015] In one embodiment, allocating resources according to the revised construction schedule and engineering quota requirement plan of the bridge project includes:

[0016] Establishing a resource waiting library in the BIM system;

[0017] Determine the idle resources of a project according to the revised construction schedule of the bridge project and the engineering quota demand plan, and enter the idle resources into the resource waiting to be transferred library;

[0018] The required resources are determined based on the revised construction schedule of the bridge project and the engineering quota demand plan of other projects, and the resources are automatically matched through the resource pool.

[0019] In one embodiment, the resource waiting library includes a company-level proprietary equipment library and a company-owned material library.

[0020] In one implementation, when automatically matching resources, the matching priority is determined based on the distance.

[0021] In one implementation, the closer the distance between the resource and the project, the higher the priority.

[0022] In one embodiment, the dynamic construction and resource allocation method for bridges based on BIM technology also includes: classifying and entering the total contract price corresponding to each process, and automatically generating actual output value statistics based on the actual construction progress of each process.

[0023] The beneficial effects brought by the technical solution provided in the embodiments of the present application include:

[0024] The present application provides a method for dynamic construction and resource allocation of bridges based on BIM technology. The entire construction period is controlled based on BIM technology. The bridge is divided into multiple components through a refined BIM model.

[0030] This embodiment provides a bridge dynamic construction and resource allocation method based on BIM technology, which includes the following steps:

[0031] Step S1, establishing a BIM model of the bridge in the BIM system, dividing the bridge into multiple components according to the BIM model, dividing the construction process of each component, and performing engineering quantity statistics;

[0032] Step S2: input the construction process, theoretical duration and connection sequence of each component into the BIM system to automatically generate a construction schedule for the bridge project;

[0033] Step S3: Determine the corresponding engineering quota according to the engineering quantity of each component, enter the engineering quota of each process into the BIM system, and automatically generate the engineering quota demand plan in combination with the bridge project construction schedule;

[0035] Step S5: Allocate resources according to the bridge project construction schedule and engineering quota demand plan.

[0036] This embodiment provides a method for dynamic construction and resource allocation of bridges based on BIM technology. The entire construction period is controlled based on BIM technology. The bridge is divided into multiple components through a refined BIM model. The construction process, theoretical duration, connection sequence and engineering quota of each component are entered into the BIM system. The bridge project construction schedule and engineering quota demand plan are automatically generated, and refined statistics are achieved. The theoretical plan is dynamically adjusted according to the actual construction progress entered, which makes the operation more convenient and more real-time, avoiding plan delays. At the same time, resources can be allocated simultaneously to improve the turnover utilization rate of equipment and materials.

[0037] Each step is described and explained in detail below.

[0038] The meanings of some nouns are as follows:

[0039] BIM: The definition of BIM by the International BIM Alliance (BuildingSMARTInternational) is:

[0040] BIM is an abbreviation of the English phrase, which stands for three different but interrelated functions.

[0041] Building Information Modeling (BIM) is a business process that generates building information and applies it to the design, construction and operation of a building, allowing stakeholders to access the same information simultaneously through the interoperability of different technology platforms.

[0042] Building Information Model (BIM): It is a digital expression of the physical and functional characteristics of a facility. It can be used as a source of information knowledge shared by relevant stakeholders of the facility and become a reliable basis for decision-making throughout the life cycle of the facility, including planning.

[0043] Building Information Management (BIM): It is the organization and control of business processes by using information in digital models, with the aim of improving the effectiveness of information sharing throughout the life cycle of assets. Its benefits include centralized and intuitive communication, early comparison of options, sustainability, effective design, professional integration, site control, completion data, etc., which can be used to effectively develop processes and models for the entire life cycle of assets from planning to retirement.

[0044] Project quota: refers to the quantity standards of labor, materials, construction machinery and equipment, construction days and related rates required to complete a qualified construction and installation project of specified measurement units under normal construction conditions.

[0045] Sub-item project: A sub-item project is a component of a single or unit project, which is a project that divides a single or unit project into several sub-items according to structural parts, road section length, construction characteristics or construction tasks; a sub-item project is a component of a sub-item project, which is a project that divides a sub-item project into several sub-items or projects according to different construction methods, materials, processes and road section lengths. It is the smallest construction project that cannot be divided any further.

[0046] In one embodiment, in step S1, the engineering quantity statistics are performed by engineering quantity statistics according to the sub-items of the project.

[0047] Through the above scheme, the engineering quantity statistics are carried out by dividing the project into parts and sub-items, and the engineering quantity statistics are more detailed, which is convenient for better organization of construction and management.

[0048] In one embodiment, in step S1, the components of the bridge include at least pile foundations, abutments, piers, main towers, main beams, and cable stays.

[0049] Through the above scheme, the bridge is divided into various main components. Of course, in other embodiments, the bridge can also be divided into more components or other forms according to actual conditions. The finer the division, the more accurate and detailed the subsequent calculation resources will be.

[0050] In step S2, the construction procedures of each component are sorted in order and then entered, and the preceding and succeeding procedures are set. The theoretical duration can be determined based on existing engineering experience, and the automatically generated bridge project construction schedule is a theoretical plan.

[0051] In step S3, when determining the corresponding engineering quota according to the engineering quantity of each component, the amount of personnel, machinery, and materials required for the engineering quantity of each process are calculated according to the corresponding specifications as resource input; when automatically generating the engineering quota demand plan in combination with the bridge project construction schedule, the plan can be generated by year, month, day or other requirements.

[0052] In one embodiment, in step S4, the bridge project construction schedule and the engineering quota demand plan are revised according to the actual construction progress, and the dynamic adjustment of the bridge project construction schedule and the engineering quota demand plan includes:

[0053] The actual construction time of the previous process is entered into the BIM system to dynamically generate the bridge project construction schedule and engineering quota demand plan for the next process.

[0054] Through the above scheme, the construction schedule of the bridge project can be dynamically adjusted according to the actual construction progress, and the engineering quota demand plan can be dynamically adjusted synchronously. The corresponding resource requirements such as personnel, machinery, and materials can be automatically calculated and counted synchronously.

[0055] In one embodiment, when the actual construction time of the previous process is entered into the BIM system, the actual start time and the actual completion time of the process are entered on a daily basis to correct the theoretical duration.

[0056] Through the above solution, the actual start time and actual completion time of the process are entered on a daily basis, and the actual construction time is controlled more accurately, which helps to improve the efficiency of the overall construction period control.

[0057] In one embodiment, step S5, allocating resources according to the revised bridge project construction schedule and engineering quota demand plan, includes:

[0058] Step S51, establishing a resource waiting library in the BIM system;

[0059] Step S52: determining the idle resources of a certain project according to the revised bridge project construction schedule and engineering quota demand plan, and entering the idle resources into the resource waiting to be transferred library;

[0060] Step S53: Determine the required resources based on the revised bridge project construction schedule and engineering quota demand plan of other projects, and automatically match the resources through the resource to-be-adjusted library.

[0061] Through the above solution, resources are automatically matched according to the dynamically adjusted bridge project construction schedule and engineering quota demand plan, which improves the turnover utilization rate of resources, enables the scheduling of materials across projects and subsidiaries, and reduces costs.

[0062] In one embodiment, the resource waiting library includes a company-level self-owned equipment library and a company-owned material library.

[0063] In one embodiment, when automatically matching resources, the matching priority is determined according to the distance. Of course, in other embodiments, other priority principles can also be adopted.

[0064] In one embodiment, the closer the resource is to the project, the higher the priority.

[0065] Through the above scheme, the regulation cost can be effectively controlled because the shorter the distance, the lower the freight.

[0066] In one embodiment, the method for dynamic bridge construction and resource allocation based on BIM technology also includes: classifying and entering the total contract price corresponding to each process, and automatically generating actual output value statistics based on the actual construction progress of each process.

[0067] The above scheme will help to count the completed project volume and actual output value and better organize the construction.
