Building construction schedule management is one of the important steps in construction management and its construction process. The existing research work related to building construction plan is mainly based on construction experience, completed relevant engineering cases or construction plan templates, which cannot realize the accurate collection of information based on specific construction projects, and then make the construction design scheme and construction site conditions to achieve dynamic and accurate matching. The construction plan and cost control strategy are optimized scientifically and efficiently. Based on BIM technology, the secondary development can convert the information, and then dynamically match the construction situation to generate the schedule, improve the accuracy and efficiency of construction projects, and dynamically optimize the building model, space structure, construction strategy, etc., thus solve the accurate positioning of the building structure in many cases, and improve the unity, efficiency, and economy of information in all aspects of building construction.
