BIM and VR technology integrate big data, internet and cloud computing into building design, construction and operation through digitization, and lead the technological change of construction industry. The popularization of BIM and VR technology puts forward new requirements for civil engineering undergraduate teaching, and it's inevitable for colleges and universities to strengthen the training of talents with BIM and VR technology. This paper introduces the application status of BIM and VR technology. Based on a summary of the problems faced by the current teaching mode of civil engineering construction, combined with the teaching mode of civil engineering construction course in China, it builds a simulation teaching system based on BIM and VR technology, and explores and implements the teaching reform method of civil engineering construction.
