This article focuses on the research of construction progress management and collaborative construction technology based on BIM technology of buildings. Firstly

BIM technology provides support of information sharing

communication and collaboration

conflict detection

and other aspects for construction collaboration. Secondly

by constructing progress models

optimizing progress simulation

etc.

it can achieve precise management of construction progress

assist in collaborative construction in aspects such as multi-disciplinary collaborative design and construction

and collaborative management of construction resources

and enable dynamic monitoring and adjustment of progress. In addition

the application of BIM technology can effectively control construction progress and improve collaborative efficiency

but there are problems such as inconsistent technical standards

insufficient personnel skills

and high costs. It is necessary to establish standards

strengthen training

and reduce costs to promote its widespread application.
