Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cost control, and particularly relates to an intelligent construction cost control method and system. Background Technique
[0002] Construction cost control refers to the process of, during the implementation of a project, based on the prediction of the project cost, through a series of effective management and control measures, strictly supervising and regulating the human, material, financial and other resources consumed during the construction process, promptly discovering and correcting deviations, so as to ensure that the actual cost of the project does not exceed the predetermined planned scope and achieve the cost target.
[0003] During the construction of building construction and municipal engineering, there are some deficiencies in the construction cost control in the project cost process of the construction party: 1. Project managers often overly focus on the cost control during the construction process, but the cost control during the construction process is often closely related to the cost management in the initial planning and design, bidding stage, and later acceptance and operation and maintenance stages of the project. As a result, there is a lack of cost planning and control for the entire life cycle of the project during construction cost control, making it difficult to optimize the overall cost, resulting in the inability to promptly discover whether there are abnormalities in different construction cycles, and at the same time, the authenticity, integrity, and timeliness of cost data cannot be guaranteed, and reliable support for cost control cannot be provided, causing decision-making mistakes or cost out-of-control for personnel; 2. Construction costs include explicit costs and implicit costs. Implicit costs include the extension of construction time caused by the construction being affected by the environment. Such construction costs cannot be predicted in a timely manner, resulting in a weakened accuracy of construction cost control; 3. When there are abnormalities in construction cost control, it is impossible to perform abnormal scheduling and supplementation of the construction costs of the project cost, further affecting the control efficiency and control convenience of construction costs.
[0004] Therefore, an intelligent construction cost control method and system are proposed to solve the above problems. Summary of the Invention

The construction environment parameters in housing construction and municipal construction are predicted based on the construction environment parameters of the three cycles. If the difference between the average value of the construction environment parameters of the three cycles and the environmental standard parameters is greater than 10, it is judged that the construction execution of the next cycle is abnormal, indicating that the construction of the next cycle is stagnant, and the reporting system sends a voice alarm; The construction early warning unit is used to receive the prediction results of the construction impact unit in real time through the data receiving instrument, and when the construction execution of the next cycle is abnormal, the reporting system sends a voice alarm.

The system according to claim 1, characterized in that: The impact scheduling end includes a result receiving module, an abnormal scheduling module, a supplement calculation module and a supplement tracking module; The result receiving module is used to receive the construction costs and construction execution prediction results corresponding to different construction processes in different periods in real time through a data receiving device; The abnormal scheduling module includes a periodic scheduling unit and a personnel scheduling unit; The periodic scheduling unit is used to set the construction cost scheduling decision according to the construction costs corresponding to different construction processes in different periods and the construction execution prediction results. The initial state of the construction cost scheduling decision is made according to the planning scheme, and the current state of the construction cost scheduling decision is made according to the abnormal construction cost results and the construction execution prediction results; The personnel scheduling unit is used to report to the system when abnormal environmental parameters are predicted for the next cycle, make scheduling adjustments to the construction space, convert outdoor work to indoor work, convert construction personnel working outdoors to construction personnel working indoors, and extend the working hours of construction personnel working outdoors.
9. The system according to claim 8, characterized in that: The supplementary calculation module is used to calculate the construction delay costs caused by environmental anomalies in real time, make up the construction delay costs for different construction processes in different periods, and repeat the real-time calculation of the construction costs; The replenishment tracking module includes a replenishment self-tracking unit and a cost control tracking unit; The complementary self-tracking unit is used to track the construction cost caused by the current state of the construction cost scheduling decision in real time through a data tracker, and calculate the difference between the construction cost caused by the current state of the construction cost scheduling decision and the construction cost caused by the initial state of the construction cost scheduling decision. If the difference is less than 0, it means that the construction cost scheduling is effective, and if the difference is greater than 0, it means that the construction cost scheduling is invalid; The cost control tracking unit is used to track the construction cost scheduling tracking results of building construction and municipal engineering in real time through a data tracker.
10. An intelligent construction cost control method according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Configure the IP address information of the construction cost remote control area server; Step 2: Enter the construction detection end, formulate a planning scheme for the construction project, detect the cost parameters of the entire life cycle of the project in real time, promptly determine whether the costs of different construction cycles are abnormal, and verify the authenticity of the data in real time. If abnormal, the reporting system will issue a cost control abnormality warning reminder and make an abnormal cycle identification signal; Step 3: Enter the cost prediction end, collect explicit costs and implicit costs in the construction process in real time, where implicit costs are set according to the environmental impact of the construction, and predict in advance whether construction will be stagnant through the environment; Step 4: Enter the impact scheduling end. When construction delays or construction stagnation occurs, the construction cost of the project cost is abnormally scheduled and supplemented in real time through the planning plan of the construction project, and the construction decision of the planning plan is adjusted to ensure construction cost control.
