This paper focuses on BIM-based structural optimization technology in construction engineering

systematically explaining the technical principles and core advantages of BIM (Building Information Modeling) technology in structural optimization of construction projects. Through practical engineering case studies

it thoroughly analyzes the practical application of BIM technology in structural design optimization

construction process optimization

and operation and maintenance phase optimization

and discusses its significant effects in improving project quality

reducing costs

and shortening construction periods. Additionally

addressing existing challenges in the application of BIM technology for structural optimization in construction projects

this study proposes corresponding solutions and development recommendations. The aim is to provide theoretical references and practical guidance for advancing the in-depth application of BIM technology in structural optimization within the construction engineering field.
