Abstract
BIM technology plays a strong role in all stages of construction projects to avoid information loss and resource loss. However, due to the high cost required for its own deployment and the reluctance of project parties to share information, the project progress and quality are adversely affected, which hinders the deployment and application of BIM technology in construction projects. The construction of BIM technology cloud platform can effectively reduce the input cost of all participants, introduce the whole process element tracking and reminding mechanism and establish the element change correlation screening mechanism, which can effectively promote the circulation and sharing of engineering information, ensure the steady progress of the project, and protect the interests of all participants.
