Abstract: Based on the whole-process engineering consulting service model, this paper designs a digital management platform suitable for such services through the research of innovative technologies like the BIM lightweight engine, BIM and GIS integration, and intelligent construction site data integration. The login page module is taken as an example to demonstrate the black-box testing process. Results show that after simulation testing with scenario methods, the expected inputs and outputs of each module meet the requirements, and the simulation performance is satisfactory.
