Abstract
The existing project cost control algorithms do not consider the task coupling characteristics in the project cost, and the calculation is easily affected by the coupling, resulting in a large mean square error. Therefore, a BIM based real-time control algorithm for complex construction cost is proposed. Firstly, BIM method is used to optimize the allocation of engineering resources. Secondly, considering the coupling of tasks in project cost, demand side management structure is used to decouple. Then, the equivalent approximate control model is established to calculate the cost factors to realize the cost control of the project. In order to verify the feasibility of the design algorithm, the simulation results show that the control response of the design algorithm is higher, and the root mean square error is lower, which meets the original intention of the design.
