Abstract: BIM technology refers to building information models. Strengthening the application of BIM technology in building construction management can effectively improve the effect of building construction management. At the same time, it provides help for the correct application of BIM technology in building model design work, and then develops a sound construction Plan, accurately collect construction information, strengthen the refinement of construction links, save construction costs while ensuring construction quality, and strengthen cost management. Based on this, this article conducts an in-depth analysis of the application of BIM technology in construction management of construction projects, aiming to provide valuable reference and reference for more people in the industry
