Abstract: The transformer substationis an important componentin the power grid project, which greatly impacts the social people's livelihood and production.The structure of the substation itself is relatively simple and regular, but with various kinds ofrelated equipment and complex circuit layout, theconstruction of substation also faces some difficulties. Inevitably, there will be some incomplete design considerations, on-site rework wastes, and progress laggings. The application of building information model technology in engineering construction management is one of the approaches to solve the above problems. This paper takes the Wendonghigh mountain 220KV substation project in Taizhou as an example, to illustrate the relative works with BIM application.
