Abstract: Following the new trend of technological and industrial innovations in which internet technologies are increasingly incorporated, "digital technology" and "digital economy" has become essential to economical and social development. Being indispensable for digitalization of the construction industry, the BIM technology has long been relying on software with American and European origins, which undermines the development of large-scale project modelling and data management. In light of the situation, an autonomous and controllable BIM technology was developed based on the BIMBase platform in this paper. By building BIM database using self-developed graphics, data management and rendering engines, the issues involving the efficiency of modelling, data management and display are addressed. The efforts above boosts the innovation of Chinese engineering and software companies.
