Taking the construction of a liquid chemical terminal in northern China as an example project，this paper builds a three-dimensional information model for the terminal project and supporting facilities according to the design drawings. Through the application of building information modeling（BIM）technologies to collision inspection of structural components，simulation of liquid loading and unloading operation areas，and visual process and technical disclosure，the paper effectively solves various problems in the design and construction process，such as the low efficiency of technical disclosure，the conflict between the installation positions of pipes and steel frames，the collision of pile shafts with pile group foundations，and the conflicts among liquid loading and unloading operation areas. The application of BIM technologies reduces communication costs and provides a technical means for fine project management. It solves the collision problem at the design stage to reduce the risk of rework during construction. This paper serves as an exploration of technical routes and solutions for the application of BIM at liquid chemical terminals.
